Description

Technical Field

[0001] The utility model relates to the technical field of fishing tools, in particular to a gravity sensing float structure based on a folded flexible circuit board. Background Art

[0002] The float is a tool that reacts to the fish biting the hook when fishing. People can judge the feeding situation of the fish through the movement of the float, and thus decide the time to lift the rod, and they can also judge which fish is biting the hook through the movement of the float, so the float is an important part of the fishing harvest.

[0045] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0046] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0047] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of the features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0048] Existing micro-circuit boards are generally long sheet structures, which occupy a relatively large volume in the inner cavity of the float body. When other functional electronic components are installed on the circuit board, the overall size will be larger, resulting in the need for a larger float body to accommodate it, which is not conducive to the float remaining afloat in the water during fishing.

[0049] The utility model provides a gravity sensing floating structure based on a folded flexible circuit board.

[0050] See also Figure 1 and Figure 2 In one embodiment of the present utility model, the gravity sensing floating structure 100 based on the folded flexible circuit board includes:

[0051] The floating body 1 has a cavity inside;

[0052] A flexible circuit board 2 is disposed in the cavity, and at least a portion of the flexible circuit board 2 is disposed in a folded state; a light emitting module 3 is disposed on the flexible circuit board 2; and

[0053] The gravity sensor 4 is disposed on the flexible circuit board 2 .

[0054] In the technical solution of the utility model, the floating structure is provided with a flexible circuit board 2 in the cavity inside the floating body 1. Since the flexible circuit board 2 can be bent and folded freely, at least a part of the circuit board can be placed in a folded state when it is set in the cavity. In this way, the volume occupied by the originally large circuit board is effectively reduced, so that the structure of the entire floating structure is more compact. When carrying and using, the user can more conveniently put the floating structure into a fishing tackle box or a fishing tackle bag, saving space and improving portability. In addition, a light-emitting module 3 and a gravity sensor 4 are also provided on the flexible circuit board 2, and the light-emitting module 3 and the gravity sensor 4 are connected in communication. In this way, during the fishing process, when a fish is hooked, the floating will sink, and the gravity sensor will sense the state change of the floating body 1, thereby generating a trigger signal and feeding it back to the light-emitting module 3. After receiving the signal, the light-emitting module 3 will change the color of the light emitted, from the original color to another color, such as from green to red. In this way, the user can also find the fish hooked in time at night or in a darker environment, which improves the success rate of fishing and the user experience.

[0055] Specifically, in this embodiment, the proportion of the folded portion of the flexible circuit board 2 is not specifically limited. For example, the proportion of the folded portion to the entire circuit board can be greater than one-fifth, or the entire flexible circuit board 2 can be folded and bent. In order to realize the intelligence and multifunctionality of the floating structure, other functional electronic components such as a single-chip microcomputer or a MOS tube can also be arranged on the flexible circuit board 2.

[0056] In one embodiment of the present invention, please refer to Figure 3 and Figure 6 At least part of the flexible circuit board 2 is folded to form a folding cavity. This design not only improves the space utilization of the circuit board, but also enhances the overall structural stability of the float. In this embodiment, the gravity sensor 4 is arranged inside the folding cavity, which can make it closer to the mechanical center of the float, and is more conducive to real-time sensing of the state change of the float in the water, thereby improving the accuracy and stability of the sensing. In addition, considering that the arrangement of the light-emitting module 3 inside the folding cavity may affect its light-emitting effect, the light-emitting module 3 is arranged outside the folding cavity in this embodiment to prevent the folding frame from interfering with the light.

[0057] In one embodiment of the present invention, please refer to Figures 3 to 8 , the flexible circuit board 2 includes:

[0058] The main body section 21 is arranged in a folded state to form a folded cavity;

[0059] The first section 22 is bent and connected to one end of the main section 21; and

[0060] The tail section 23 is bent and connected to the other end of the main section 21 , and the tail section 23 is disposed close to the first section 22 .

[0061] Specifically, the flexible circuit board 2 in this embodiment includes three parts: a main section 21, a first section 22 and a tail section 23. The main section 21 is the core part of the flexible circuit board 2, which is arranged in a folded state to form a stable folding cavity. This folding design not only improves the space utilization of the circuit board, but also enhances the overall structural stability of the float. Various electronic components, such as a gravity sensor 4, a single-chip microcomputer, etc., can be arranged inside the folding cavity to meet the intelligent and multifunctional requirements of the float. The first section 22 and the tail section 23 are respectively bent and connected to the two ends of the main section 21, and their main function is to connect the main section 21 with other circuit parts, such as power supply, signal line, etc. The design of the first section 22 takes into account the stability and reliability of the connection to ensure the efficient operation of the entire circuit board. In addition, the first section 22 and the tail section 23 are arranged close to each other, which can provide a stable support to protect the various electronic components inside the circuit board.

[0062] In one embodiment of the present invention, please refer to Figure 3 and Figure 6 , the main body section 21 includes:

[0063] The first folding portion 211 is bent and connected to the first section 22;

[0064] The second folding portion 212 is bent and connected to the first folding portion 211;

[0065] The third folding portion 213 is bent and connected to the second folding portion 212 , and one end of the third folding portion 213 away from the second folding portion 212 is bent and connected to the tail section 23 .

[0066] Specifically, the main section 21 in this embodiment adopts a unique multi-folding part design to adapt to the special use environment and functional requirements of the float. The main section 21 mainly includes three folding parts: a first folding part 211, a second folding part 212 and a third folding part 213. The design of three folding parts can not only improve the space utilization of the circuit board, but also protect the internal electronic components and prevent damage to the electronic components. In addition, the first folding part 211 and the third folding part 213 are respectively bent and connected to the first section 22 and the tail section 23, so that the circuit board can still maintain good connection performance during the folding process.

[0067] In one embodiment of the present invention, the flexible circuit board 2 can be arranged in two folding ways. The first folding way is: Figure 3 , the first section 22 and the tail section 23 are at least partially overlapped to close the folding cavity, and the tail section 23 is superimposed on the side of the first section 22 away from the folding cavity; this folding method not only allows the circuit board to form a complete closed structure after folding, but also enhances the wear resistance and pressure resistance of the circuit board. During fishing, the float may be affected by various external factors, such as the pulling of the fishing line, the impact of water flow, etc., and this overlapping design can effectively reduce the impact of these factors on the circuit board and ensure the normal operation of the circuit board. The second folding method is, please refer to Figure 6 The first section 22 includes a first extension portion 221 and a second extension portion 222 that are bent and connected to each other. The first extension portion 221 is bent and connected to the main body end, and the first extension portion 221 and the second extension portion 222 are bent in opposite directions. This bending design in opposite directions can keep the circuit board balanced during the folding process, avoiding deformation or damage caused by unilateral bending. The tail section 23 includes a third extension portion 231 and a fourth extension portion 232 that are bent and connected to each other. The third extension portion 231 is bent and connected to the main body end, and the third extension portion 231 and the fourth extension portion 232 are bent in opposite directions. This bending design in opposite directions can keep the circuit board balanced during the folding process, avoiding deformation or damage caused by unilateral bending; wherein the first extension portion 221 and the fourth extension portion 232 have the same bending direction, and the second extension portion 222 and the third extension portion 231 have the same bending direction. This symmetrical bending design not only makes the appearance of the circuit board more beautiful, but also improves the balance and stability of the circuit board. It should be noted that, in order to enhance the stability and elasticity of the first section 22 and the tail section 23 of the flexible circuit board 2, the first section 22 and the tail section 23 of the utility model are both composed of two extensions, and the first section 22 and the tail section 23 are double folded. This design not only extends the setting length of the first section 22 and the tail section 23, but also improves the elasticity of these two parts, so that they can be effectively electrically connected to the power supply. The specific folding method can be selected according to actual needs.

[0068] In one embodiment of the present invention, please refer to Figure 5The flexible circuit board 2 also includes a positive electrode sheet 24 and a negative electrode sheet 25. The negative electrode sheet 25 is provided on the side of the first section 22 facing the outside of the folding cavity, and the positive electrode sheet 24 is provided on the side of the tail section 23 facing the outside of the folding cavity. When the first section 22 and the tail section 23 of the flexible circuit board 2 are folded, in the folded flexible circuit board 2, the positive electrode sheet 24 is provided on the side away from the folding cavity, and the negative electrode sheet 25 is superimposed on the side of the positive electrode sheet 24 facing the folding cavity. At this time, there is a positive electrode sheet 24 between the negative electrode sheet 25 and the needle tube battery 5, and it cannot make contact with the negative electrode of the power source. In order to facilitate the electrical connection of the positive and negative electrodes of the flexible circuit board 2 and other power sources, respectively, mutually connected avoidance holes 233 are provided on the positive electrode sheet 24 and the tail section 23, and the avoidance holes 233 are provided corresponding to the negative electrode sheet 25, so that the negative electrode of the power source can pass through and be electrically connected to the negative electrode sheet 25.

[0069] In one embodiment of the present invention, please refer to Figure 4 Since the positive electrode sheet 24 and the negative electrode sheet 25 are usually thin, they are prone to breakage or damage during use, thereby affecting the performance of the entire flexible circuit board 2. In order to improve the strength of the two electrode sheets, the flexible circuit board 2 also includes at least two reinforcing sheets 26, and at least one reinforcing sheet 26 is provided on the side of the first section 22 and the tail section 23 facing the inside of the folding cavity. The function of the reinforcing sheet 26 is to provide additional support and reinforcement so that the electrode sheet can better resist deformation and breakage when subjected to external force. It should be pointed out that the reinforcing sheet 26 is provided on the side of the first section 22 and the tail section 23 facing the inside of the folding cavity. In this way, it will not only not hinder the setting of the electrode sheet, but also ensure that the electrode sheet can effectively bear part of the stress when folded or bent, thereby reducing the burden on the electrode sheet.

[0070] In one embodiment of the present invention, please refer to Figure 1 , Figure 2 and Fig. 9The gravity-sensing floating structure 100 based on the folding flexible circuit board also includes a needle-tube battery 5, which is electrically connected to the flexible circuit board 2 to ensure the normal operation of the flexible circuit board 2 without the need for an external power supply, which is convenient for users to use. The negative electrode of the needle-tube battery 5 is a tubular negative electrode 51. This design enables the battery to better adapt to the bending and folding of the flexible circuit board 2. The tubular negative electrode 51 of the needle-tube battery 5 passes through the avoidance hole 233 and is electrically connected to the negative electrode sheet 25, which improves the connection stability between the battery and the flexible circuit board 2. Furthermore, the positive electrode of the needle tube battery 5 can be electrically connected to the positive electrode sheet 24 in two ways. One way is that when the first section 22 and the tail section 23 of the flexible circuit board 2 are overlapped, the negative electrode sheet 25 and the positive electrode sheet 24 are both arranged in the horizontal direction. Due to the arrangement of the tubular negative electrode 51, there is a gap between the positive electrode of the needle tube battery 5 and the positive electrode sheet 24 of the flexible circuit board 2, and they cannot be directly contacted. At this time, the positive electrode of the needle tube battery 5 can be electrically connected to the positive electrode sheet 24 through a conductive spring 6, and the conductive spring 6 can maintain good electrical contact performance. Another way is that when the tail section 23 includes two mutually bent extensions, the positive electrode sheet 24 on the tail section 23 can be arranged closer to the positive electrode of the needle tube battery 5 through the arrangement of the extension. At this time, the positive electrode of the needle tube battery 5 can be directly electrically connected to the positive electrode sheet 24. This connection method is simple and reliable, and can effectively reduce the internal resistance of the battery and increase the service life of the battery. It should be noted that the two extension portions of the tail section 23 need to be provided with corresponding avoidance holes 233 for the tubular negative electrode 51 to pass through, so as to achieve electrical connection with the negative electrode sheet 25 .

[0071] In one embodiment of the present invention, please refer to Figure 1 , the light emitting module 3 comprises:

[0072] A light-guiding optical fiber 31 is disposed in the cavity, and the light-guiding optical fiber 31 extends to the outside of the floating body 1; and

[0073] The light source 32 is disposed in the cavity and electrically connected to the flexible circuit board 2 , and the light source 32 is electrically connected to the light guiding optical fiber 31 .

[0074] Specifically, the light emitting module 3 includes a light-guiding optical fiber 31 and a light source 32, and the light source 32 is electrically connected to the light-guiding optical fiber 31, so that the light emitted by the light source 32 can be guided to the outside of the floating body 1 through the light-guiding optical fiber 31. In this way, even if the floating body 1 is made of opaque material, the state and position of the float can be observed in real time in a dark environment. The light source 32 in this embodiment can be an LED lamp, or it can be other structures that generate light, as long as it is a lighting structure that occupies a small volume and can emit lights of different colors. Of course, in other embodiments, when the floating body 1 is made of a light-transmitting material, the light-guiding optical fiber 31 may not be provided.

[0075] In one embodiment of the present invention, please refer to Figure 3 , Figure 6 and Fig. 9 The light source 32 is a SMD LED lamp. Compared with the plug-in LED lamp, the SMD structure is flatter, which is conducive to further reducing the volume occupied by the flexible circuit board 2 in the cavity. The response time of the SMD LED lamp is extremely fast, and it can reach full brightness almost instantly. In addition, the LED lamp can emit light of various colors, for example, it can include two kinds of light, red and green. In order to find the position of this floating structure when fishing in a darker environment, the LED lamp can emit green light, and when a fish bites the hook, it will be converted into red light, so that the user can find the light emitted by the LED lamp in time, and observe the information of the fish biting the hook conveniently, quickly and accurately, further increase the visual sensitivity of the angler, and experience a good effect.

[0076] In one embodiment of the present invention, please refer to Figure 3 , Figure 4 , Figure 6 and Figure 7 The gravity sensing floating structure based on the folding flexible circuit board also includes a single chip microcomputer 7, which is arranged on the flexible circuit board, and the gravity sensor and the light emitting module are both connected to the single chip microcomputer 7 in communication. In this embodiment, the single chip microcomputer 7 works closely with the flexible circuit board 2, the gravity sensor 4 and the light emitting module 3 to form an efficient and stable system. In addition, the single chip microcomputer 7, as the core control unit, is responsible for receiving the signal from the gravity sensor 4, and processing and analyzing it. When the single chip microcomputer 7 detects that the signal of the gravity sensor 4 changes, it will immediately determine whether this is due to the change of the floating state caused by the fish being hooked. If so, the single chip microcomputer 7 will further issue an instruction to control the light emitting module 3 to change the color of the light to remind the user. In addition, the single chip microcomputer 7 can also adjust the working mode of the light emitting module 3 according to the needs of the user and the changes in the environment. For example, at night or in an environment with low visibility, the single chip microcomputer 7 can control the light emitting module 3 to emit brighter light; and during the day or in an environment with sufficient light, the single chip microcomputer 7 can control the light emitting module 3 to emit darker light to reduce interference with the fish.

[0077] In another embodiment of the present invention, please refer to Figure 3 , Figure 4 , Figure 6 and Figure 7The gravity-sensing float structure based on the folding flexible circuit board also includes a MOS tube 8. A MOS tube 8 can also be provided on the flexible circuit board 2, and the MOS tube 8 is communicatively connected with the single-chip computer 7. The MOS tube 8 has the advantages of fast switching speed, low on-resistance, and large driving current. In the utility model, the main function of the MOS tube 8 is to increase the brightness of the green light emitted by the light-emitting module 3. Specifically, when the single-chip computer 7 needs to adjust the brightness of the light-emitting module 3, it will send a control signal to change the size of the driving current of the MOS tube 8, thereby changing the brightness of the light emitted by the light-emitting module 3. In this way, the single-chip computer 7 can realize precise control of the brightness of the light-emitting module 3, meet the needs of users in different environments and usage scenarios, and further improve the fun and success rate of fishing.

All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
