Description

Technical Field

[0001] This utility model belongs to the technical field of sports and fitness products, specifically relating to a composite bow with a built-in sight and a composite bow equipped with the sight. Background Technology

[0002] In traditional compound bow designs, the sight is typically mounted on the outside of the bow shaft, creating a protruding section. On one hand, this protruding sight increases the overall size of the compound bow, severely impacting portability and making it susceptible to damage from impacts during outdoor carrying or transportation. On the other hand, traditional sights often feature bulky, half-pin designs, resulting in lower accuracy during aiming and a poor user experience, failing to meet the demands of high-precision shooting.

[0003] In existing technologies, some improvements focus on replacing the sight's materials, such as using lightweight materials like aluminum alloys and carbon fiber to reduce its weight. However, these improvements do not change the sight's external core structure, and therefore cannot solve the problems of its bulkiness and susceptibility to damage. Regarding the sight's structure, some improvements only increase material strength, without innovating key performance aspects such as the sight's refined design and optimized aiming accuracy, making it difficult to fundamentally improve the user experience.

[0004] Given the technical shortcomings of traditional composite bow sights, the development of a sight that combines portability, safety, and high precision has become an urgent need for the industry. Utility Model Content

[0005] This utility model aims to provide a composite bow built-in sight. By integrating the sight inside the bow body, it makes full use of the bow body space. Combined with innovative designs such as ultra-fine sights and integrated structure, it effectively solves the problems of size, protection, and accuracy of traditional sights, and provides a new solution for the development of composite bow sight technology.

[0006] Based on the first major aspect of this utility model, a composite bow built-in sight is provided, the sight being disposed inside the bow body of the composite bow and held between two support plates of the bow body;

[0007] The sight includes a sight ring, within which is a sight assembly consisting of an intersecting horizontal and vertical pin.

[0008] As a further preferred embodiment, the mounting position of the sight extends from the center of the bow handle to both ends by no more than 1 / 3 of the total length of the bow.

[0009] As a further preferred embodiment, the sight also includes a mounting component and a connecting component;

[0010] The mounting component is connected to the bow body via fixing and adjustment holes;

[0011] One end of the connector is connected to the mounting piece, and the other end is connected to the aiming ring.

[0012] As a further preferred embodiment, a sight adjustment platform is provided at the top and bottom of the sight ring, and multiple horizontal needles are arranged parallel to each other between the sight adjustment platforms at the top and bottom, and the two ends of one or more vertical needles are set on the sight adjustment platform.

[0013] Furthermore, the vertical needle can be adjusted by connecting it to different lateral positions on the aiming needle adjustment platform.

[0014] As a further preferred embodiment, the horizontal and / or vertical needles are made of ultra-fine wire with a diameter of 0.15-0.3 mm;

[0015] The ultra-fine wire includes fishing line, carbon fiber wire, or titanium alloy wire.

[0016] As a further preferred embodiment, the aiming pin adjustment platform is equipped with a micro tension adjustment structure for adjusting the wire tension, with a tension adjustment range of 0.5-2N.

[0017] Sight installation:

[0018] The mounting component is connected to the bow body by a locating pin or bolt. The fixing and adjustment holes include locating holes and adjustment slots for fine-tuning the mounting position of the sight.

[0019] As a further preferred embodiment, the aiming ring and connector are made of carbon fiber composite material or aluminum alloy, wherein the fiber volume content of the carbon fiber composite material is ≥65%.

[0020] The overall weight of the sight is ≤200g.

[0021] As a further preferred embodiment, the outline of the aiming ring includes a circle, an ellipse, a rhombus, or a regular polygon.

[0022] As a further preferred option, the sight is installed in a position that avoids the movement areas of the bow's wheel assembly, bow limbs, main string, and secondary string, ensuring normal drawing and firing of the compound bow;

[0023] The aiming ring is installed with its vertical axis perpendicular to the direction of the compound bow's draw string, and its deviation from the bow's deformation center axis is ≤2mm.

[0024] Based on the first main aspect of this utility model, a composite bow is provided, including the aforementioned sights.

[0025] Compared with the prior art, the present invention has at least the following significant advantages:

[0026] Firstly, the prevalence of externally mounted composite bow sights presents three major technical challenges: First, space constraints. The sight protrudes from the outside of the bow, increasing its overall width by 15-25mm, significantly reducing portability and making it susceptible to damage from impacts during outdoor use. Second, limited protection. The lack of effective protection makes the sight vulnerable to impacts during transport or use, potentially causing the sight pin to deform or the connectors to loosen, affecting aiming accuracy. Third, limited aiming precision. Traditional sights employ a large, half-pin structure, typically ≥1mm in diameter, and offer only a single adjustment method, making it difficult to meet the ±1mm accuracy requirements of modern competitive shooting.

[0027] This invention achieves the following breakthrough improvements by integrating the sights inside the bow body:

[0028] First, this invention achieves a reduction in overall size. By eliminating the outer support, the bow's width is restored to its state without a sight, reducing the overall width by 15-25mm and significantly improving portability.

[0029] Secondly, this invention improves structural protection. Because the sight is held between the two support plates of the bow body, a physical barrier is formed, increasing its impact resistance by more than three times. Tests have shown that it can withstand a 200N lateral impact force without damage.

[0030] Third, this invention optimizes the spatial adaptation of the compound bow. Because the sight is positioned to avoid moving parts such as the wheel assembly and main string, the normal operation of the compound bow is ensured. Simultaneously, the adjustable slots on the fixing and adjusting holes allow for ±3mm three-dimensional fine-tuning, adapting to different user body types.

[0031] Fourth, this invention achieves a qualitative leap in accuracy through the innovative design of the sight assembly: This invention uses 0.15-0.3mm ultra-fine wire (such as fishing line or titanium alloy wire), with a diameter only 1 / 3-1 / 5 of that of traditional sights, reducing visual interference by 70%. Combined with the crosshair structure, this improves aiming accuracy from the traditional ±5mm to ±1.5mm. Furthermore, the vertical needle in this invention can be adjusted horizontally by ±5mm, and with the micro-tension adjustment device (0.5-2N tension range), rapid calibration of targets at different distances is achieved. Testing shows that it can cover ±20cm of ballistic compensation at a distance of 50 meters. In addition, the sight adjustment platform of this invention adopts a dual-platform support structure, combined with a threaded rod locking design, ensuring wire sag ≤0.1mm and vibration attenuation rate of 90%, guaranteeing the stability of the sight position during firing.

[0032] Finally, this utility model achieves multiple technological breakthroughs through systematic design: the overall volume of the composite bow is reduced by 18%, and the weight is reduced by 0.3kg, making it easy to hold with one hand and significantly improving its convenience for outdoor use; the entire structure is made of carbon fiber composite material (fiber volume content ≥65%), the sight weight is ≤200g while the strength is increased by 50%, and the temperature resistance range is extended to -40℃~120℃; through the modular sight design, the sight ring can be quickly replaced with various contours such as round and oval to adapt to different aiming needs, and the vertical pin adjustment range covers ±15° elevation compensation, making it suitable for various shooting scenarios.

[0041] The preferred embodiments of this utility model will be described in detail below to provide a clearer understanding of its purpose, features, and advantages. It should be understood that the following embodiments are not intended to limit the scope of this utility model, but are merely illustrative of its essential spirit.

[0042] In the following description, certain specific details are set forth for the purpose of illustrating various disclosed embodiments in order to provide a thorough understanding of the various disclosed embodiments. However, those skilled in the art will recognize that embodiments may be practiced without one or more of these specific details. In other instances, well-known techniques associated with this application may not have been shown or described in detail to avoid unnecessarily obscuring the description of the embodiments.

[0043] Throughout this specification, references to "an embodiment" or "an embodiment" indicate that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment. Therefore, the appearance of "in an embodiment" or "in an embodiment" in various places throughout the specification does not necessarily refer to the same embodiment. Furthermore, a particular feature, structure, or characteristic may be combined in any way in one or more embodiments.

[0044] like Figure 1 and Figure 2 As shown, the composite bow built-in sight 2 of this utility model is installed in the middle area inside the bow body 103 (with the center of the bow handle 110 as the reference, extending to both ends no more than 1 / 3 of the total length of the bow body 103), and is clamped by two support plates of the bow body 103.

[0045] This design reduces the width of the bow by 15-25mm, achieving both size reduction and improved portability.

[0046] Meanwhile, the two support plates of the bow body 103 are equipped with a hollow structure, which not only achieves lightweight design, but also enhances the overall aesthetics.

[0047] For the composite bow 1, a lighting fixture 104 can also be clamped onto the bow body 103 for mounting a lighting lamp to enable night shooting. A shock-absorbing device 105 can also be installed, which acts as a counterweight to balance the stability of the bow body 103.

[0048] like Figure 3 and Figure 4 As shown, the sight 2 of this utility model has the following structural composition:

[0049] (1) Basic components:

[0050] Mounting component 201: Adopts an L-shaped structure design and connects to the bow body 103 via fixing and adjusting holes 202. The fixing and adjusting holes 202 include... The positioning hole and the 15mm long × 5mm wide adjustment slot allow for ±3mm lateral fine adjustment.

[0051] Connector 203: A double-rod structure made of carbon fiber composite material, with a rod diameter of 8mm. Both ends are connected to mounting part 201 and aiming ring 204 respectively via bolts, or welded to mounting part 201 and aiming ring 204 to form an integral structure. Figure 3 (The design adopts an integrated approach).

[0052] Aiming circle 204: In Figure 3 and Figure 4 The device features a circular outline design (50mm in diameter) and an annular groove on the inner wall for securing the aiming pin assembly.

[0053] (2) Sight system

[0054] The aiming pin adjustment platform 205 is symmetrically arranged at the top and bottom of the aiming ring 204. The platform is 10mm wide and has horizontal positioning holes spaced 2mm apart on its surface.

[0055] Horizontal Needle 206: Uses high-strength fishing line with a diameter of 0.2mm. Figure 4 The CCP sets up 7 rods, arranged in parallel between the upper and lower platforms, with a spacing of 3-6mm. The spacing can be designed to be the same or gradually changing.

[0056] Vertical needle 207: Made of titanium alloy wire with a diameter of 0.25mm, both ends are fixed to the platform positioning holes by a micro tension adjustment device (including threaded rod and lock nut), which can be adjusted by ±5mm in the lateral direction.

[0057] The horizontal needle 206 and the vertical needle 207 form a crosshair. In almost all cases, there is only one vertical needle 207, which intersects with multiple parallel horizontal needles 206 in sequence to form multiple crosshairs. Different crosshairs formed by the horizontal needles 206 and the vertical needles 207 correspond to targets at different distances, making it easier for the operator to aim according to the distance.

[0058] The sight 2 of this invention can also be mounted on the side of the bow body 103.

[0059] This sight 2 of the present invention does not contain a lens structure similar to that of a firearm scope, effectively preventing light glare. Furthermore, the design, which uses multiple horizontal pins 206 intersecting with a vertical pin 207 to form the front sight, is more suitable for use with bows and arrows. Therefore, the sight 2 of the present invention can also be used on other types of shooting equipment.

[0060] In implementation of this utility model, lateral fine-tuning is achieved through the adjusting groove of the mounting component 201, and longitudinal fixation is achieved in conjunction with the positioning pin, ensuring that the installation accuracy of the sight 2 and the bow 103 reaches ±0.5mm. All bolt connections adopt a double-nut locking structure to prevent loosening caused by shooting vibration.

[0061] Anchor 2 can be equipped with a tension adjustment device (including a threaded rod and a locking nut). The threaded rod has a pitch of 0.5mm, and the tension of the wire is adjusted by rotation. The measured sag under 0.5N tension is ≤0.1mm, and the breaking strength under 2N tension is ≥50N.

[0062] An angle adjustment structure can also be added. That is, the vertical pin 207 is connected to the platform via a rotating shaft, and with the locking bolt, an angle adjustment of ±5° can be achieved, with an adjustment accuracy of 0.5°.

[0063] This invention is made entirely of carbon fiber composite material. The bow body 103 and main components are made of T700 grade carbon fiber prepreg with a fiber volume content of 65%. The aiming ring 204 can be manufactured by compression molding with a density of 1.6 g / cm³. 3 It reduces weight by 30% compared to aluminum alloy.

[0064] The overall weight of the sight is approximately 180g, of which mounting part 201 accounts for approximately 30g, connecting part 203 accounts for approximately 30g, and sight ring 204 accounts for 120g.

[0065] The following alternative solutions can also be designed:

[0066] First, the shape of the 204 aiming ring can be optimized. For example, an elliptical aiming ring with a major axis of 60mm, a minor axis of 50mm, and a wall thickness of 2.5mm can be used, suitable for wide field-of-view aiming needs. Alternatively, a polygonal aiming ring, such as a hexagonal design, can be used to increase the grip surface and facilitate manual adjustment.

[0067] Secondly, the material of the aiming pin can be expanded. High-strength fibers can be used, such as aramid fibers (e.g., Kevlar), with a diameter of 0.15 mm and a tensile strength ≥3.6 GPa. Alternatively, metal wire can be used, such as tungsten wire with a diameter of 0.3 mm and a Young's modulus of 411 GPa, to improve resistance to deformation.

[0068] Third, the installation structure can be improved. For example, a magnetic installation can be designed, with the mounting component 201 containing a neodymium iron boron magnet (N42 grade) that cooperates with the steel insert of the bow body 103 to achieve quick assembly and disassembly. Alternatively, an elastic buffer layer can be designed, such as a 3mm thick nitrile rubber pad on the contact surface between the mounting component 201 and the bow body 103, to reduce vibration transmission.

[0069] Finally, the adjustment function can be upgraded. For example, an electric adjustment system can be adopted, integrating a micro stepper motor (step angle 1.8°) into the aiming pin adjustment platform 205, enabling ±10mm lateral adjustment and tension control via remote control. Alternatively, a laser calibration module can be designed, integrating a laser emitter (wavelength 635nm) on the top of the aiming ring 204, working in conjunction with the laser receiver on the bow body 103 to achieve automatic calibration.

[0070] This invention has undergone accuracy testing. In 10 shots at a 10cm bullseye from a distance of 20 meters, the radius of impact point distribution using the built-in sight is ≤2cm, representing a 40% improvement in accuracy compared to traditional sights. The overall width of the compound bow has been reduced from the traditional 120mm to 95mm, and the weight has been reduced by 0.3kg.

[0071] This utility model's troubleshooting solution includes: a quick-release sight assembly for easy cable replacement, allowing for cable replacement within 30 seconds via a press-type buckle. It also incorporates a waterproof design, with an O-ring (Shore A hardness 70A) at the 204 stainless steel seam of the sight ring, achieving an IP65 protection rating.

[0072] like Figure 5 As shown, in the second embodiment of the sight 2 of this utility model, the sight 2 includes a double sight ring 204 structure, with one sight ring 204 in front and the other sight ring 204 in the rear. Each of the two sight rings 204 contains a sight pin structure consisting of a horizontal pin 206 and a vertical pin 207. In this design, the mounting member 201 is located between the two sight rings 204, and the mounting member 201 is connected to the front and rear sight rings 204 via connecting members 203 in both directions. Furthermore, the mounting member 201 is provided with screw holes for mounting the sight 2 onto the bow body 103.

[0073] Among them, connector 203 adopts a hollow design.

[0074] Of course, the sight 2 can also be set as a whole cylindrical structure.

[0075] and Figure 3 and Figure 4 The difference between the first embodiment and the second embodiment is that in this embodiment, the arrangement of the aiming pin adjustment platform 205 on the front aiming ring 204 is similar to that in the first embodiment, but the aiming pin adjustment platform 205 is respectively set in the upper and lower and left and right directions of the aiming ring 204, so that both the vertical needle 207 and the horizontal needle 206 can be adjusted.

[0076] In this embodiment, the aiming pins within the two aiming rings 204 are aligned with each other as a reference, thereby achieving better target aiming and improving hit accuracy.

[0077] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
