Description

Technical Field

[0001] The utility model relates to the field of fishing gear, in particular to a fish finder. Background Art

[0002] With the improvement of living standards, fishing has become a form of entertainment for the public, and fishing gear is a must-have tool for many fishing enthusiasts. When fishing at night, a camera with lighting is used to detect the underwater situation, so as to accurately find a suitable place for fishing or fishing.

[0003] Most of the existing fish finders use infrared rays for underwater lighting at night. The fish finder includes an outer cover, a camera, and an infrared lamp for lighting. The infrared lamp is arranged around the camera. In order to improve the infrared lighting effect and avoid the situation where the light emitted by the infrared lamp is reflected by the outer cover and affects the camera's shooting effect, the infrared lamp is usually attached to the side wall of the outer cover or fixed on the side of the outer cover.

[0004] The applicant believes that an electrical connection is required between the infrared lamp and the power supply, so the infrared lamp can only be set at a position close to the power supply at the bottom of the camera to simplify the electrical connection circuit of the infrared lamp. This low-position setting results in a relatively small lighting range of the infrared lamp. Utility Model Content

[0005] In order to expand the lighting range of the infrared lamp, the utility model provides a fish finder.

[0006] The utility model provides a fish finder adopting the following technical solution:

[0007] A fish finder comprises an outer cover, a camera and an infrared lamp, wherein the infrared lamp is arranged on the top of the camera and is arranged in the same direction as the camera lens, so that the infrared ray emission direction of the infrared lamp is the same as the direction in which the camera receives the light.

[0008] The infrared lamp is set on the top of the camera, and the height of the infrared lamp is raised by the height of the camera shape, so that the infrared lamp has a wider irradiation range. The infrared lamp and the camera lens are set in the same direction to avoid the angle difference of the light from the two, so that the illumination range of the infrared lamp can be fully captured by the camera, and the light range with zero angle difference makes the camera's shooting range brighter.

[0009] Preferably, the camera rotates in the outer cover, and the infrared lamp rotates synchronously with the camera.

[0010] When the camera rotates, it drives the infrared lamp fixedly connected thereto to rotate synchronously. The camera can take pictures 360°. The infrared lamp illuminates synchronously with the camera, illuminating the range that the camera can shoot in all directions, avoiding the method of setting multiple infrared lamps in traditional fish finders, which is beneficial to saving electricity.

[0011] Preferably, the pins of the infrared lamp penetrate through the housing of the camera, and the infrared lamp is directly electrically connected to the camera main board.

[0012] The power supply of the fish finder powers the camera, and the infrared lamp is electrically connected to the camera. Therefore, the camera can power the infrared lamp, avoiding the situation of leading out connecting wires from the top of the camera to connect the infrared lamp and the power supply, and at the same time avoiding the situation that the connecting leads of the infrared lamp affect the rotation of the camera.

[0013] Preferably, the outer cover is provided with a light shielding portion, and the light shielding portion is provided between the infrared lamp and the camera.

[0014] The setting of the light shielding portion can reduce the situation of lateral projection or refraction of light downward after the infrared lamp irradiates on the outer cover, and reduce the situation that the infrared rays "flowing" to the camera affect the color of the camera imaging, which is beneficial to improving the stability of the lighting effect after the infrared lamp is set on the top of the camera.

[0015] Preferably, the light shielding portion extends along the circumferential direction of the outer cover, and the end portion of the light shielding portion along the circumferential direction of the outer cover is closed.

[0016] Since the camera can rotate 360°, the light shielding portion provided along the circumferential direction of the outer cover can provide a comprehensive and meticulous light shielding effect for the camera.

[0017] Preferably, a base is provided under the outer cover. The base is a metal base, the power supply is placed in the base, and the camera is rotatably connected to the base.

[0018] The setting of the base makes the overall fish finder have a top-light and bottom-heavy mass ratio. When the fish finder is placed in water, the fish finder is affected by the buoyancy of the water. Since the base of the fish finder is heavier, the base is always located below the camera. Therefore, when the fish finder is placed in water, it can automatically adjust to the state where the base touches the ground with the cooperation of the buoyancy of the water.

[0019] Preferably, the outer cover includes an illumination section and an imaging section. The illumination section wraps around the infrared lamp, the imaging section wraps around the camera. The volume of the illumination section is set to adapt to the volume of the infrared lamp, the volume of the imaging section is set to adapt to the volume of the camera, and the volume of the illumination section is much smaller than the volume of the imaging section.

[0020] Reducing the volume of the illumination section can reduce the volume and weight of the outer cover, making the weight difference between the base and the device above the base larger. At the same time, it can reduce the area irradiated by the infrared lamp on the outer cover, thereby weakening the refractive index and side projection rate of the infrared rays on the side wall of the outer cover, making the illumination effect of the infrared rays more stable.

[0021] In summary, the present utility model includes the following beneficial technical effects:

[0022] The infrared lamp is arranged at the top of the camera. By using the height of the camera's outer shape, the height of the infrared lamp is increased, making the irradiation range of the infrared lamp wider. The infrared lamp and the camera lens are arranged in the same direction, which can avoid the angular difference between the two lights, enabling the illumination range of the infrared lamp to be fully captured by the camera, and the light range with zero angular difference makes the brightness of the camera's shooting range higher.

[0025] The following will further describe the present utility model in detail Figure 1 with reference to the accompanying drawings.

[0026] An embodiment of the present utility model discloses a fish finder.

[0027] Referring to Figure 1 , a fish finder includes an outer cover 2, a base 1, a camera 5, and an infrared lamp 3. The outer cover 2 is arranged on the base 1 so that a sealed space is formed inside the outer cover 2 to accommodate the camera 5 and the infrared lamp 3, and both the camera 5 and the infrared lamp 3 are arranged on the base 1.

[0028] Referring to Figure 1 , the inner peripheral wall of the outer cover 2 is provided with internal threads, and the outer peripheral wall of the top of the base 1 is provided with external threads adapted to the outer cover 2. The outer cover 2 and the base 1 are detachably connected through threaded cooperation.

[0029] The base 1 is a metal base. In this embodiment, the outer cover 2 is made of acrylic board. In other embodiments, the outer cover 2 can be made of other transparent materials, but the weight of the outer cover 2 should be less than the weight of the base 1 to make the overall fish finder form an "upper-light-lower-heavy" tumbler state. When the fish finder is placed in water, the fish finder is subjected to the buoyancy of the water. Since the base 1 of the fish finder is heavier, the base 1 is always located below the camera 5. Therefore, when the fish finder is placed in water, it can automatically adjust to the state where the base 1 touches the ground under the cooperation of the buoyancy of the water.

[0030] Referring to Figure 1 , the outer cover 2 includes an illumination section 22 and an imaging section 21. The illumination section 22 is wrapped around the infrared lamp 3, and the imaging section 21 is wrapped around the camera 5. The volume of the illumination section 22 is set to adapt to the volume of the infrared lamp, and the volume of the imaging section 21 is set to adapt to the volume of the camera 5. The volume of the illumination section 22 is much smaller than the volume of the imaging section 21.

[0031] Reducing the volume of the illumination section 22 can reduce the volume and weight of the outer cover 2, making the weight difference between the base 1 and the devices above the base 1 larger. At the same time, it can reduce the area irradiated by the infrared lamp 3 on the outer cover 2, thereby weakening the refractive index and side projection rate of the infrared rays on the side wall of the outer cover 2, making the illumination effect of the infrared rays more stable.

[0032] Referring to Figure 1 , a power supply and a circuit board are provided inside the base 1. The power supply can supply power to the camera 5. The main board inside the camera 5 is electrically connected to the circuit board. The camera 5 is rotatably connected to the base 1. The specific rotational connection structure includes but is not limited to a turntable provided on the base 1.

[0033] The infrared lamp 3 is fixedly arranged on the top of the camera 5. Utilizing the height of the camera 5 itself to increase the height of the infrared lamp 3 enables a wider irradiation range of the infrared lamp 3. When the camera 5 rotates, it drives the infrared lamp 3 fixedly connected thereto to rotate synchronously. The camera 5 can take pictures at 360°. The infrared lamp 3 illuminates synchronously with the camera 5, illuminating the range that the camera 5 can photograph in all directions, avoiding the method of setting multiple infrared lamps 3 in traditional fish finders, which is beneficial for saving electricity.

[0034] Moreover, the irradiation range of the light emitted by the infrared lamp 3 is set in the same direction as the shooting range of the light received by the camera 5. When the camera 5 rotates, it drives the infrared lamp 3 to rotate synchronously. The infrared lamp 3 being arranged in the same direction as the lens of the camera 5 can avoid the angular difference between the two lights, enabling the illumination range of the infrared lamp 3 to be fully photographed by the camera 5, and the light range with zero angular difference makes the shooting range of the camera 5 brighter.

[0035] The pins of the infrared lamp 3 penetrate through the top wall of the camera 5 and are electrically connected to the main board of the camera 5. The power supply of the fish finder supplies power to the camera 5, and the infrared lamp 3 is electrically connected to the camera 5. Therefore, the camera 5 can supply power to the infrared lamp 3, avoiding the situation of having to lead out connecting wires from the top of the camera 5 to connect the infrared lamp 3 and the power supply, and at the same time avoiding the situation where the connecting leads of the infrared lamp 3 affect the rotation of the camera 5.

[0036] Both the imaging section 21 and the illumination section 22 are cylindrical. The outer cover 2 is provided with an infrared-blocking light-shielding portion 4, which is arranged between the infrared lamp 3 and the camera 5. The light-shielding portion 4 extends along the circumferential direction of the outer cover 2, and the circumferential ends of the light-shielding portion 4 along the outer cover 2 are closed. In this embodiment, the light-shielding portion 4 is arranged on the imaging section 21 and extends along the circumferential direction of the imaging section 21 until it is closed. In other embodiments, the light-shielding portion 4 can be arranged on the illumination section 22, or can be arranged on both the imaging section 21 and the illumination section 22 at the same time.

[0037] The setting of the light-shielding portion 4 can reduce the situation of lateral light projection or light refraction downward after the infrared lamp 3 irradiates on the outer cover 2. The light-shielding portion 4 can be set as a black strip, and the shape of the strip is not limited. It can reduce the situation that the infrared rays "flowing" to the camera 5 affect the color of the imaging of the camera 5, which is beneficial to improving the stability of the illumination effect after the infrared lamp 3 is arranged on the top of the camera 5. Since the camera 5 can rotate 360°, the light-shielding portion 4 arranged along the circumferential direction of the outer cover 2 can comprehensively and carefully provide a light-shielding effect for the camera 5.

[0038] The above are all the preferred embodiments of the present invention, and the protection scope of the present invention is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
