Description

Technical Field

[0001] The invention relates to the technical field of vehicle-mounted cameras, and in particular to a camera mounting bracket for an unmanned vehicle. Background Art

[0002] An unmanned vehicle refers to a vehicle that can travel automatically without the need for a human driver. All unmanned vehicles are equipped with on-board cameras, which are instruments that record images, sounds and other related information while the vehicle is driving. The on-board camera can have the function of presenting video and audio in real time. The on-board camera is usually installed on the inner wall of the front windshield of the car. The existing on-board camera is a small camera connected to a bracket, and the bracket is glued to the front windshield during installation. The structure is simple and the installation is convenient. When adjusting the angle of the on-board camera, the small camera is usually directly rotated to adjust the shooting angle of the on-board camera. The operation is simple. However, the above method will have the problem of excessive angle deflection when rotating the small camera, and manual adjustments need to be made multiple times to determine the accurate shooting position. The accuracy of the angle adjustment of the small camera needs to be improved, and it is also easily affected by external factors after adjustment, resulting in angle deviation.

[0003] Existing vehicle-mounted cameras also have a method of electrically adjusting the angle. For example, Chinese invention patent publication number CN112040125A discloses a vehicle-mounted camera, which drives a rotating shaft to rotate through a stepper motor, and the rotating rotating shaft drives a driving block and a driving column to rotate, thereby driving the vehicle-mounted camera body to rotate slowly. The user can easily adjust the angle of the vehicle-mounted camera body, reducing the steps of manual adjustment by the user, thereby making it easier for the user to use the vehicle-mounted camera.

[0004] However, the above electric adjustment operation only limits the rotation angle of the vehicle camera through the stepper motor. After the vehicle camera has been used for a period of time, the shooting angle will shift due to bumps in the road, and the angle of the vehicle camera needs to be readjusted, thereby reducing the stability and accuracy of the vehicle camera's shooting.

DETAILED DESCRIPTION

[0033] The embodiments of the present invention are described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways as defined and covered by the claims.

[0036] See also Figure 1 , Figure 2 and Figure 6The lower end of the rectangular plate 11 is provided with an auxiliary support member that is linked with the arc strip 13 through a linkage member. The rotating plate 12 drives the arc strip 13 to rotate and simultaneously causes the auxiliary support member to rotate in the opposite direction through the linkage member. The linkage member includes a gear 130 that is rotatably mounted at the lower end of the rectangular plate 11 through an ear plate and is located on the left side of the rectangular hole.

The auxiliary support member includes a contact arc plate 131 that is provided on the left side of the arc strip 13 and is slidably matched with the lower end of the rectangular plate 11 and is co-centered with the arc strip 13. The outer arc surface of the contact arc plate 131 is also provided with teeth that mesh with the gear 130 for transmission. The lower end of the contact arc plate 131 is hinged with an elastic block 132.

[0037] See also Figure 6 The limiting unit 14 includes a second spring telescopic rod 141 installed on the right hole wall of the rectangular hole, and an L-shaped limiting rod 142 is installed on the left end of the second spring telescopic rod 141. The horizontal section of the L-shaped limiting rod 142 passes through the left hole wall of the rectangular hole and is plugged into any limiting groove on the arc strip 13.

[0038] See also Figure 1 , Figure 5 and Figure 6 During the specific operation, the double-sided tape for fixing is manually pasted on the rotating plate 12. According to the inclination angle of the front windshield of the car to be installed, the L-shaped limit rod 142 is manually pulled to the right, and the L-shaped limit rod 142 is moved out of the limit groove on the arc strip 13. Then the rotating plate 12 is rotated, and the rotating plate 12 drives the arc strip 13 to rotate. When the gear 130 is engaged with the teeth on the arc strip 13, the arc strip 13 rotates and the gear 130 cooperates with the arc strip 131 to drive the elastic block 132 to rotate in the opposite direction to the rotation direction of the arc strip 13.

The rotating plate 12 can adjust the angle of the entire device, which is convenient for pasting on front windshields with different inclination angles, thereby improving the flexibility of the pasting mechanism 1.

[0039] See also Figure 1 and Figure 6The placing mechanism 4 includes a rectangular frame 41 installed on the left end face of the adjusting mechanism 3 through a rectangular block, and square holes are opened on the upper and lower side walls of the rectangular frame 41.

[0040] See also Figure 1 and Figure 6 During specific operation, the camera module 5 is manually inserted into the rectangular frame 41. The camera module 5 is an existing camera. The square hole on the rectangular frame 41 is used for heat dissipation of the camera module 5 and the threading of the wires connected to the camera module 5. The camera module 5 is continued to be pushed. The camera module 5 squeezes the first spring telescopic rod 42 through the moving plate 43. After the camera module 5 moves into the rectangular frame 41, the two limiting U-shaped plates 44 are rotated toward each other. After the middle vertical section of the limiting U-shaped plate 44 moves to the left side of the camera module 5, the camera module 5 is released. The first spring telescopic rod 42 drives the camera module 5 to be in close contact with the middle vertical section of the limiting U-shaped plate 44 through the moving plate 43, thereby realizing the limiting fixation of the camera module 5.

[0041] See also Figure 6 The adjusting mechanism 3 includes a circular ring 31 installed inside the rotating mechanism 2. A fan-shaped hole is opened on the ring wall of the circular ring 31 near the left side. An arc-shaped limit frame 32 coaxial with the ring wall of the circular ring 31 is fixedly connected to the ring wall of the circular ring 31 near the right side through a screw. The opening of the arc-shaped limit frame 32 is on the same side as the fan-shaped hole. An auxiliary block is installed in the middle of the inner ring surface of the arc-shaped limit frame 32. The screw slides through the auxiliary block. The inner ring surface of the circular ring 31 is rotatably connected with a clamping unit 33 through a bearing. A moving unit 34 is installed on the clamping unit 33, and a lifting unit 35 is installed on the upper end of the arc-shaped limit frame 32.

[0042] See also Figure 1 , Figure 5 and Figure 6The clamping unit 33 includes a rotating tube 331 rotatably connected to the inner ring surface of the circular ring 31 through a bearing, and two placement grooves symmetrically arranged about its axis are provided on the outer ring surface of the rotating tube 331. A rectangular bar 332 is arranged in the rotating tube 331, and an isosceles triangular prism is installed on the rear end surface of the rectangular bar 332. The front end of the rectangular bar 332 is slidably penetrated and matched with the front wall of the rotating tube 331. A rotating cap 333 is installed at the front end of the rectangular bar 332. The front wall of the rotating cap 333 is provided with two guide columns 334 symmetrically arranged about its axis. The guide column 334 is T-shaped, and the guide column 334 is threadedly connected to the front end of the rotating tube 331. The guide column 334 penetrates and slides with the rotating cap 333. A clamping branch chain 335 is connected in the placement groove, and a rubber ring is arranged on the inner ring surface of the rotating cap 333, and the rubber ring slides and matches with the outer ring wall of the front end of the rotating tube 331.

[0043] See also Figure 5 The front end surface of the circular ring 31 is provided with a plurality of plug-in holes evenly arranged along its circumference, and the rear end surface of the rotating cap 333 is provided with a protrusion that matches with any of the plug-in holes.

[0044] See also Figure 5 , Figure 6 and Figure 7 The clamping branch chain 335 includes a lifting rod 3351 that slides through the inner groove wall of the placement groove, and a clamping plate 3352 is installed at the end of the lifting rod 3351 away from the rectangular bar 332. A connecting spring 3353 is installed between the clamping plate 3352 and the inner groove wall of the placement groove. The connecting spring 3353 is sleeved on the outer side of the corresponding lifting rod 3351, and an anti-slip pad 3354 is installed at the end of the clamping plate 3352 away from the corresponding lifting rod 3351. A ball is rotatably connected to the end of the lifting rod 3351 close to the rectangular bar 332, and the ball slides together with the isosceles triangular prism and the outer ring wall of the rectangular bar 332.

[0045] See also Figure 5-Figure 7When working specifically, in the initial state, the rotating cap 333 and the rotating tube 331 are in a separated state. According to the shooting angle required by the camera module 5, the rotating cap 333 is manually rotated, and the rotating cap 333 drives the rotating tube 331 to rotate in the circular ring 31 through the rectangular bar 332. The rotating tube 331 drives the camera module 5 in the rectangular frame 41 to rotate through the moving unit 34, thereby realizing the function of adjusting the angle of the camera module 5 with a horizontal axis. After the camera module 5 moves to the required angle, the rotating cap 333 is manually pushed, and the rotating cap 333 drives the isosceles triangular prism on the rectangular bar 332 to push the balls on the upper and lower lifting rods 3351, and the lifting rod 3351 is driven by force to drive the clamping plate 3352 to move toward the inner ring surface direction of the circular ring 31 The clamping plate 3352 drives the anti-skid pad 3354 to fit tightly against the inner surface of the circular ring 31, thereby realizing the positioning function of the rotating tube 331 and preliminarily fixing the shooting angle of the camera module 5. This can prevent the camera module 5 from angular deviation during use. At the same time, the rotating cap 333 drives the rubber ring to contact the rotating tube 331. The rubber ring increases the friction between the rotating cap 333 and the rotating tube 331, thereby preventing the rotating cap 333 from moving from the rotating tube 331 before installing the guide column 334. At the same time, the protrusion is inserted into the corresponding plug-in hole to limit the rotation of the rotating cap 333, thereby improving the connection stability between the circular ring 31 and the rotating cap 333, and further facilitating the improvement of the stability of the camera module 5 after the angle is adjusted. Then the guide column 334 is installed.

[0046] See also Figure 1 and Figure 6 The movable unit 34 includes a connecting rod 341 placed in the fan-shaped hole, the right end of the connecting rod 341 is fixedly connected to the rotating tube 331, the left end of the connecting rod 341 is installed with an arc plate 342, the rectangular block is fixedly installed in the middle of the outer ring surface of the arc plate 342, and buffer springs 343 are installed at the upper and lower ends of the arc plate 342. The end of the buffer spring 343 away from the arc plate 342 is fixedly connected to the auxiliary block. Initially, the end of the arc plate 342 is located between the outer ring wall of the rotating tube 331 and the inner ring surface of the arc limit frame 32.

[0047] See also Figure 1 , Figure 5 and Figure 6 During specific operation, when the rotating tube 331 rotates, the arc plate 342 is driven to rotate through the connecting rod 341. The arc plate 342 rotates and squeezes the buffer spring 343 on one side of its rotation, and the buffer spring 343 on the other side is stretched, and at the same time drives the camera module 5 in the rectangular frame 41 to rotate. The buffer spring 343 plays a buffering role in the movement of the arc plate 342, avoiding the arc plate 342 from moving too far during manual rotation, thereby improving the accuracy of the angle adjustment of the camera module 5 and reducing the time required for manual repeated adjustment.

[0048] See also Figure 1 and Figure 5 The lifting unit 35 includes a clamping frame 351 installed at the upper and lower ends of the arc-shaped limit frame 32. The left and right side walls of the clamping frame 351 are provided with through holes near the lower side. The clamping frame 351 is threaded and penetrated by a clamping screw 352. A traction rope 353 is passed through the two through holes on the clamping frame 351. A limit ring 354 is installed at the right end of the traction rope 353, and the left end of the traction rope 353 is fixedly connected to the rectangular frame 41.

[0049] See also Figure 1 , Figure 5 and Figure 6 When working specifically, in the initial state, the clamping screw 352 does not contact the traction rope 353 part in the clamping frame 351. After the angle adjustment of the camera module 5 is completed, the traction rope 353 is tightened and the clamping screw 352 is rotated. The clamping screw 352 presses the traction rope 353 on the inner wall of the clamping frame 351 to limit the traction rope 353, thereby limiting the rectangular frame 41. The upper and lower traction ropes 353 simultaneously apply tension to the rectangular frame 41, increasing the force points of the rectangular frame 41, which is conducive to maintaining the angular stability of the rectangular frame 41 at this time, and avoiding the rectangular frame 41 from deviating up and down when the car drives on a bumpy road section. Under the joint action of the clamping plate 3352 driving the anti-skid pad 3354 to be in close contact with the inner ring surface of the circular ring 31 and the traction rope 353, the stability of the camera module 5 during shooting is improved, and the limiting ring 354 limits the traction rope 353 to avoid the traction rope 353 from moving out of the clamping frame 351.

[0050] See also Figure 1 , Figure 5 and Figure 6 The rotating mechanism 2 includes a rotating rod 21 that passes through the upper and lower ends of the rectangular plate 11 and is rotatably connected to the rectangular plate 11. A U-shaped frame 22 with an opening facing downward is installed at the lower end of the rotating rod 21. The inner end surface of the vertical section of the U-shaped frame 22 is fixedly connected to the circular ring 31. A guide cavity is arranged inside the rotating rod 21. A T-shaped rod 23 is slidably connected to the upper wall of the rotating rod 21. A circular plate 24 located above the rectangular plate 11 is installed at the upper end of the vertical section of the T-shaped rod 23. A plurality of circumferentially uniformly distributed limiting teeth are installed on the annular surface of the circular plate 24. Two limiting arc plates 25 are symmetrically arranged on the left and right sides of the circular plate 24. The lower end of the limiting arc plate 25 is fixedly connected to the rectangular plate 11. A plurality of uniformly distributed triangular teeth are installed on the opposite surface of the limiting arc plate 25, and the triangular teeth cooperate with the limiting teeth.

[0051] During specific operation, according to the required shooting angle, the circular plate 24 is manually lifted up and rotated. The circular plate 24 drives the rotating rod 21 to rotate through the T-bar 23. The rotating rod 21 drives the adjusting mechanism 3, the placing mechanism 4 and the camera module 5 to rotate as a whole through the U-frame 22, thereby changing the horizontal shooting angle of the camera module 5, realizing the adjustment of the horizontal angle of the camera module 5, and improving the flexibility of the use of the camera module 5. Then, the circular plate 24 is pressed downward, and the limiting teeth on the circular plate 24 are plugged into and matched with the triangular teeth on the limiting arc plate 25, thereby limiting the circular plate 24, and further limiting the rotation angle of the camera module 5.

[0052] See also Figure 1-Figure 7 When in use, S1: manually stick the double-sided tape used for fixing on the rotating plate 12, manually pull the L-shaped limit rod 142 to the right according to the inclination angle of the front windshield of the car to be installed, and the L-shaped limit rod 142 moves from the limit groove on the arc strip 13, and then rotate the rotating plate 12, and the rotating plate 12 drives the arc strip 13 to rotate. When the gear 130 is engaged with the teeth on the arc strip 13, the arc strip 13 rotates and the gear 130 cooperates with the arc strip 131 to drive the arc strip 131 to rotate. The elastic block 132 rotates in the direction opposite to the rotation direction of the arc strip 13. After the rotating plate 12 moves to the corresponding angle, the L-shaped limit rod 142 is released, and the second spring telescopic rod 141 drives the L-shaped limit rod 142 to reset and inserts the horizontal section of the L-shaped limit rod 142 into the corresponding limit groove on the arc strip 13, thereby limiting the position of the rotating plate 12, and then the rotating plate 12 is pasted on the front windshield from the inside of the car with double-sided tape. At this time, the elastic block 132 adaptively presses against the front windshield.
