Description

Technical Field

[0001] This utility model relates to the field of satellite navigation camera technology, specifically a satellite navigation camera device. Background Technology

[0002] Car satellite navigation is an intelligent system based on global satellite positioning systems (such as GPS and Beidou) that uses in-vehicle devices to determine the vehicle's location in real time and provide route guidance. Its core function is to combine satellite signals with map data to improve driving efficiency and safety. To expand their functions, most existing in-vehicle navigation devices can be connected to external camera devices for drivers to use.

[0003] The aforementioned device lacks a structure for negative pressure fixation and multi-angle adjustable fixation of the camera during use. This means that most existing navigation extension cameras can only be connected in a fixed position using screws or clips during installation and use. The camera extension flexibility is poor, and it is impossible to install the camera on the windshield or side window for the driver's use as needed. Based on the shortcomings of the existing technology, this utility model designs a satellite navigation camera device. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a satellite navigation camera device that has the advantages of negative pressure fixation and multi-angle adjustable fixation of the camera.

[0005] This utility model provides the following technical solution: a satellite navigation camera device, comprising a satellite navigation main body, a camera main body disposed at the rear of the satellite navigation main body, and a fixing mechanism disposed below the camera main body for quick fixation to glass using negative pressure.

[0006] The fixing mechanism includes a fixed base plate, a negative pressure cylinder, a threaded cylinder, a negative pressure hole, a bottom groove, a sealing ring, a negative pressure plate, a threaded column, and a screw head. The fixed base plate is located below the camera body. The negative pressure cylinder is fixedly connected to the upper surface of the fixed base plate. The threaded cylinder is fixedly connected to the upper surface of the negative pressure cylinder. The negative pressure hole is opened through the bottom of the negative pressure cylinder. The bottom groove is opened at the bottom of the negative pressure cylinder. The sealing ring is fixedly connected inside the bottom groove. The negative pressure plate slides and rises inside the negative pressure cylinder. The threaded column is rotatably connected to the upper surface of the negative pressure plate. The screw head is fixedly connected to the top of the threaded column.

[0007] As a preferred technical solution of this utility model, a fixed frame is fixedly connected to the outside of the camera body, and side shafts are fixedly connected to both sides of the fixed frame. An adjustment groove is opened on the side shaft, and an upper support plate is rotatably connected to the side shaft. A limit rod is fixedly connected to the outside of the upper support plate, and a first fixing nut is threaded on the limit rod. A rotating shaft is fixedly connected to the bottom outside of the upper support plate, and a second fixing nut is threaded on the rotating shaft. A lower support plate is slidably connected to the rotating shaft, and an adjustment vertical groove is opened through the lower support plate.

[0008] In a preferred embodiment of this invention, a light shield is fixedly connected to the front of the satellite navigation body, and a back connecting frame is fixedly connected to the back of the satellite navigation body. A connecting seat is rotatably connected to the back connecting frame, and a wire is fixedly connected to the back of the connecting seat.

[0009] As a preferred embodiment of this utility model, the threaded column is rotatably connected to the threaded cylinder.

[0010] As a preferred embodiment of this utility model, the negative pressure plate slides and rises above the negative pressure hole.

[0011] As a preferred embodiment of this utility model, the limiting rod is slidably inserted into the inside of the adjusting groove, and the first fixing nut is clamped and fixed on the outside of the side shaft.

[0012] As a preferred embodiment of this utility model, the rotating shaft slides and lifts inside the adjusting vertical groove, and the second fixing nut is clamped and fixed on the outside of the lower support plate.

[0013] In a preferred embodiment of this invention, the other end of the wire is connected to the camera body.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This satellite navigation camera device, after the camera body is connected to the satellite navigation body via a wire, places the fixing plate at the bottom of the camera body on the glass of the installation area, ensuring the sealing ring at the bottom of the fixing plate fits tightly against the glass. Then, the screw head is slowly turned clockwise to rotate the threaded column. The rotating threaded column, through its threaded connection with the threaded cylinder, slowly moves upward, pulling the negative pressure plate upward as well. At this time, the space between the negative pressure plate and the glass increases, but the pressure decreases, thus using negative pressure to firmly adhere and fix the fixing plate and the negative pressure cylinder to the glass, thereby fixing the camera body. After fixing the camera body, the first and second fixing nuts can be loosened to loosen the connection between the side shaft, the upper support plate, and the lower support plate, allowing adjustment of the camera body's height and angle. After adjustment, the first and second fixing nuts are tightened to lock it in place. This device facilitates fixing the camera body to the windshield or side window. Attached Figure Description

[0026] Please see Figure 3-4A fixed frame 201 is fixedly connected to the outside of the camera body 2. Side shafts 202 are fixedly connected to both sides of the fixed frame 201. An adjustment groove 203 is provided on the side shafts 202. An upper support plate 204 is rotatably connected to the side shafts 202.

[0028] Working principle: When a satellite navigation camera device is used, in the initial state, one end of the wire 104 is first placed on the back of the satellite navigation body 1, and the other end of the wire 104 is connected to the camera body 2. A back connecting bracket 102 and a connecting seat 103 are provided at the bottom of the satellite navigation body 1, so that the satellite navigation body 1 can perform satellite navigation while simultaneously using the wire 104 to enable the satellite navigation body 1 to also function as a camera. Side shafts 202 are provided on both sides of the fixed frame 201 fixedly connected to the camera body 2. The side shafts 202 rotate upwards. The bottom end of the upper support plate 204 is connected to the lower support plate 209 and the fixed base plate 301 via a rotating shaft 207 and a second fixing nut 208, so as to fix the position of the camera body 2 or adjust its height and angle. The bottom of the negative pressure cylinder 302, which is fixedly connected to the fixed base plate 301, is provided with a negative pressure hole 304, a bottom groove 305 and a sealing ring 306. The negative pressure plate 307 inside the negative pressure cylinder 302 is controlled by the threaded cylinder 303 and the threaded column 308, so as to use negative pressure to fix the camera body 2 arbitrarily on the windshield for use.

[0029] When it is necessary to fix the camera body 2 to the windshield or side window, first, after the camera body 2 completes the signal connection with the satellite navigation body 1 through the wire 104, place the fixing plate 301 at the bottom of the camera body 2 on the glass of the installation area, so that the sealing ring 306 at the bottom of the fixing plate 301 fits tightly with the glass. Then, slowly turn the screw head 309 clockwise to drive the threaded column 308 to rotate. The rotating threaded column 308 slowly moves upward through the threaded connection with the threaded cylinder 303 and pulls the negative pressure plate 307. As it moves upward, the space between the negative pressure plate 307 and the glass increases, but the pressure decreases. This negative pressure is used to firmly adhere the fixed base plate 301 and the negative pressure cylinder 302 to the glass, thereby fixing the camera body 2. After fixing the camera body 2, the first fixing nut 206 and the second fixing nut 208 can be loosened to loosen the connection between the side shaft 202, the upper support plate 204 and the lower support plate 209, allowing adjustment of the height and angle of the camera body 2. After adjustment, the first fixing nut 206 and the second fixing nut 208 can be tightened to lock it. This device makes it easy to fix the camera body 2 to the windshield or side window.
