Description

Technical Field

[0001] The present application relates to the field of vehicle-mounted lenses, and in particular to a jig that can adjust the distance and angle between the lens and the chip to achieve clear lens imaging during actual image shooting in high and low temperature environments. Background Art

[0002] With the rise of intelligent manufacturing, demand for smart technology is growing, especially in the automotive sector. Intelligent driving is becoming increasingly integrated into vehicle features, becoming a competitive advantage for automakers. Features such as 360-degree surround view, reversing cameras, and automatic parking are becoming increasingly common. In-vehicle imaging systems are becoming increasingly common, and in-vehicle imaging lenses are also gaining widespread use.

[0003] Currently, most lens fixtures for real-world imaging rely on a screw connection on the fixture to adjust the lens's image clarity. This method is affected by the gap between the lens and fixture threads. Furthermore, because the fixture is typically fixed directly to the chip board, the chip's position cannot be adjusted, resulting in tilt and offset between the lens and the imaging chip. The gap between the lens and fixture threads is also affected by thermal expansion and contraction, affecting the lens's focusing accuracy. Furthermore, because the lens and fixture are connected by screw threads and have rotational play, certain lens performance tests cannot be quantified, such as the actual focal shift of the lens during high and low temperature experiments. This makes it impossible to accurately determine the lens's quality during these experiments.

[0004] A Chinese patent discloses a three-axis adjustable small gimbal (authorization publication number: CN108349593B). The disclosed gimbal may include: a first supporting body; a lens barrel, which includes a lens group and is connected to the first supporting body in a manner that is rotatable around a first axis; a roll drive unit, which is installed at a first position on the lens barrel to provide a force for rotating the lens group around the first axis and a perpendicular second axis; a pitch drive unit, which is installed to the first supporting body to provide a force for rotating the lens group around the first axis; a second supporting body, which is connected to the first supporting body in a manner that is rotatable around a third axis, the third axis being perpendicular to each of the first axis and the second axis; and a yaw drive unit, which is installed to the second supporting body to allow the first supporting body to rotate around the third axis.

[0005] In the above-mentioned three-axis adjustable small gimbal, the lens and the imaging surface are set as an integrated design, and the three-axis gimbal is used to adjust the imaging angle; the design can only change the distance between the lens and the imaging surface, but cannot change the angle between the lens and the imaging surface. When an offset occurs between the lens and the imaging surface, imaging distortion or even the inability to form an image will occur. Summary of the Invention

[0058] Example 1

[0059] See also Figures 1-6 , this embodiment provides a tool for shooting images with an adjustable lens.

[0060] The adjustable lens real-time image jig includes a base 1, a rotating platform 2, a pendulum column 3, a three-axis gimbal 4, a lens unit 5, and an imaging unit 6. The base 1 adopts a rectangular parallelepiped structure, including a top surface, a bottom surface, and side surfaces surrounding the four sides of the base 1. A hinge hole is provided on the top surface of the base 1. The hinge hole is a through hole that passes through the base 1 and connects the top and bottom surfaces of the base 1. A screw hole is symmetrically provided on each side of the hinge hole. The hinge hole is used for hinge connection with the rotating platform 2. The screw hole is used to install the first limit block. The screw hole is also configured as a through hole, passes through the base 1, and extends to the bottom surface of the base 1.

[0061] The rotating table 2 is hinged on the top surface of the base 1. The width of the rotating table 2 is set to be smaller than the width of the base 1, and the length of the rotating table 2 is also set to be smaller than the length of the base 1. The base 1 is a rectangular structure, and a hinge hole is also opened at the center of the base 1. The positions of the hinge holes of the rotating table 2 and the base 1 correspond to each other. By installing a hinge at the connection between the base 1 and the rotating table 2, and the hinge connecting the hinge hole of the rotating table 2 and the hinge hole of the base 1, the connection between the rotating table 2 and the base 1 is realized, and the rotating table 2 can rotate on the top surface of the base 1, and according to the connection position of the hinge, the rotation state of the rotating table 2 is that the rotation axis is parallel to the Z-axis direction.

[0062] The corresponding hinge holes on the base 1 and the rotating table 2 are also provided with fixing bolts, and the fixing bolts include a screw and a nut, and the screw includes a screw head and a stud; the screw is inserted into the base 1 from the hinge hole on the bottom surface of the base 1, and the nut is fixed on the hinge hole of the rotating column, and the screw passes through the base 1 and the rotating table 2 and is connected with the nut and bolt; the structure is set up, which can fix the positional relationship between the base 1 and the rotating table 2 after the rotating table 2 is rotated to a suitable angle to prevent it from rotating again and causing position deviation.

[0063] The turntable 2 is provided with an arc-shaped first limiting groove 21. The first limiting groove 21 can be set as at least one, and the center of any first limiting groove 21 must coincide with the rotation axis of the turntable 2; the first limiting groove 21 can be opened on the bottom surface of the turntable 2 and set to not pass through the bottom and top surfaces of the turntable 2; the first limiting groove 21 can also be set to pass through the bottom and top surfaces of the turntable 2.

[0064] In this embodiment, the specific structure is to set two first limit grooves 21, and the first limit grooves 21 are both arc-shaped with a size of 1 / 6 of a circle, and the radii of the two first limit grooves 21 are equal; the first limit grooves 21 both pass through the bottom and top surfaces of the turntable 2; when the turntable 2 is hinged on the top surface of the base 1, the first limit block is limited in the first limit groove 21, thereby realizing the limitation of the rotation angle of the turntable 2, and the first limit block slides inside the first limit groove 21.

[0065] The left and right side surfaces of the base 1 are provided with mounting grooves 11, and the mounting grooves 11 are used to install the pendulum column 3. The mounting grooves 11 are connected to the top surface of the base 1. A mating surface 12 is provided in the mounting groove 11, and the mating surface 12 is perpendicular to the direction of the X-axis. A hinge hole is also provided on the mating surface 12, and the hinge hole is provided in the middle of the mating surface 12. The hinge hole is used to be hinged to the pendulum column 3. A screw hole is symmetrically provided on the left and right sides of the hinge hole, and the screw hole is used to install the second limit block.

[0066] The side of the pendulum column 3 close to the base 1 is defined as the inner side 33, and the side of the pendulum column 3 away from the base 1 and opposite to the fitting surface is defined as the outer side 34. When the pendulum column 3 is installed in the mounting groove 11, the inner side 33 is hinged with the mating surface 12, and the outer side 34 is flush with the side of the base 1. The width of the outer side 34 is set to be smaller than the width of the mating surface 12. Such a structure can ensure that there is a gap between the pendulum column 3 and the mounting groove 11. The gap is used to allow the pendulum column 3 to rotate smoothly in the mounting groove 11 without colliding with the groove wall of the mounting groove 11 during rotation. A hinge hole is opened near the bottom end of the pendulum column 3. The hinge hole on the pendulum column 3 corresponds to the hinge hole on the mating surface 12. A hinge is installed between the pendulum column 3 and the mating surface 12. The hinge connects the mating surface 12 and the pendulum column 3, allowing the pendulum column 3 to rotate relative to the mating surface 12. The bottom surface of the pendulum column 3 is symmetrically provided with inclined surfaces 32 on both sides. The inclined surfaces 32 configure the bottom surface of the pendulum column 3 into a chamfered structure. The two inclined surfaces 32 are used to reduce the volume on both sides of the bottom surface of the pendulum column 3 so that the bottom surface of the pendulum column 3 will not conflict with the mounting groove 11 when the pendulum column 3 rotates, which is more conducive to the smooth rotation of the pendulum column 3; an arc surface is also provided between the two inclined surfaces 32. The arc surface is used to form a line-surface contact between the bottom surface of the pendulum column 3 and the bottom surface of the mounting groove 11 when the pendulum column 3 rotates, so that the rotation of the pendulum column 3 is more stable, and it also plays a certain supporting role on the pendulum column 3.

[0067] When the pendulum column 3 swings in the mounting groove 11 and has not swung to the extreme position, line-to-surface contact is formed between the arc surface and the bottom surface of the mounting groove 11; when the pendulum column 3 swings to the extreme position, separation occurs between the arc surface and the bottom surface of the mounting groove 11, and at the same time, surface-to-surface contact is formed between the inclined surface 32 and the bottom surface of the mounting groove 11, making the state of the pendulum column 3 at the extreme position more stable.

[0068] The pendulum column 3 is provided with a second limiting groove 31, and the second limiting groove 31 can be set as at least one, and the center of any second limiting groove 31 must coincide with the rotation axis of the pendulum column 3; the second limiting groove 31 can be provided on the inner side surface 33 of the pendulum column 3 and configured not to pass through the inner side surface 33 and the outer side surface 34 of the pendulum column 3; the second limiting groove 31 can also be configured to pass through the inner side surface 33 and the outer side surface 34 of the pendulum column 3.

[0069] In this embodiment, the specific structure is to set two second limit grooves 31, and the second limit grooves 31 are both arc-shaped with a size of 1 / 6 circle, and the radii of the two second limit grooves 31 are equal; the second limit grooves 31 both pass through the inner side surface 33 and the outer side surface 34 of the pendulum column 3; when the pendulum column 3 is hinged on the mating surface 12, the second limit block is limited in the second limit groove 31, thereby realizing the limitation of the rotation angle of the pendulum column 3, and the second limit block slides inside the second limit groove 31.

[0070] An internal thread is also provided in the hinge hole of the mating surface 12, and a screw is provided in the hinge hole of the pendulum column 3, and the screw passes through the hinge and the internal thread of the mating surface 12 to be screwed together; by setting the connection structure, when the pendulum column 3 swings to a suitable position, the positional relationship between the pendulum column 3 and the mating surface 12 can be tightened by the screw, thereby fixing the angle and position between the pendulum column 3 and the base 1, and preventing the pendulum column 3 from swinging again and causing position deviation.

[0071] The rotation of the turntable 2 and the pendulum 3 is achieved by the hinge between the base 1, the turntable 2 and the pendulum 3. The rotation axis of the turntable 2 is parallel to the Z axis; the rotation axis of the pendulum 3 is parallel to the X axis.

[0072] A three-axis gimbal 4 is bolted to the top surface of the rotating table 2. The three-axis gimbal 4 can rotate with the rotating table 2, and the three-axis gimbal 4 can perform fine-tuning of displacement in the X, Y, and Z axis directions; a lens head 5 is bolted to the top surface of the three-axis platform. The lens head 5 includes a fixing seat 51 and a lens 53. The fixing seat 51 includes a base plate 511 and a connecting plate 512 arranged on the base plate 511. The base plate 511 and the connecting plate 512 are perpendicular to each other. The base plate 511 is used to be bolted to the three-axis gimbal 4, and the lens 53 is installed in the middle of the connecting plate 512.

[0073] When the rotating table 2 rotates with the Z-axis as the rotation axis, it drives the three-axis pan-tilt head 4 to rotate, and the three-axis pan-tilt head 4 drives the fixed seat 51 to rotate, and finally drives the lens 53 to rotate; when the lens 53 rotates with the Z-axis as the rotation axis, the angle between the lens 53 and the imaging chip 62 in the X-axis direction changes, thereby realizing the adjustment of the angle in the X-axis direction.

[0074] When the three-axis gimbal 4 performs fine-tuning of the displacement in the X, Y, and Z directions, it drives the lens 53 to perform fine-tuning of the displacement together; the three-axis gimbal 4 also includes three positioning members, which are used to lock and unlock the displacement in the X, Y, and Z directions respectively.

[0075] The pendulum columns 3 are provided in two pieces, and the two pendulum columns 3 are respectively hinged in the mounting grooves 11 at both ends of the base 1. The top of the pendulum column 3 is provided with a groove, and the groove is provided with a screw hole.

[0076] The adjustable lens real-shot image jig also includes an imaging part 6, which includes a fixing plate 61 and an imaging chip 62 arranged in the middle of the fixing plate 61; specifically, a square hollow is provided in the middle of the fixing plate 61, and the imaging chip 62 is bolted to the hollow; screw holes are provided at the left and right ends of the fixing plate 61, and the fixing plate 61 is bolted to the grooves on the two pendulum columns 3 through the screw holes at both ends.

[0077] The hollowing is used to dissipate heat for the imaging chip 62 .

[0078] At this time, when the pendulum column 3 rotates in the mounting groove 11 with the X-axis direction as the rotation axis, the pendulum column 3 drives the fixed plate 61 to rotate, and the imaging chip 62 on the fixed plate 61 also rotates with the X-axis direction as the rotation axis; the angle formed by the imaging chip 62 and the lens 53 in the Z-axis direction changes, thereby realizing the adjustment of the angle in the Z-axis direction.

[0079] The depth of the groove is set to be equal to half the length of the outer surface 34. Regardless of how the pendulum column 3 swings, the position of the center of gravity of the imaging unit 6 projected on the Y-axis is always within the range occupied by the mounting groove 11 on the Y-axis, thereby making the swing of the pendulum column 3 and the imaging unit 6 more stable.

[0080] In summary, the angle adjustment and distance adjustment between the lens 53 and the imaging chip 62 are achieved through the movement of the rotating platform 2, the pendulum column 3 and the three-axis pan-tilt head 4.

[0081] Example 2

[0082] See also Figures 1-6 , based on the above embodiment, another embodiment is provided.

[0083] An adapter ring 52 is also provided between the lens 53 and the connecting plate 512; a first mounting hole 513 is provided in the middle of the connecting plate 512; the aperture of the first mounting hole 513 is set to be much larger than the diameter of the lens 53; the adapter ring 52 is installed in the first mounting hole 513; the adapter ring 52 includes a part for connecting with the first mounting hole 513 and a part for connecting to the lens 53, and a second mounting hole 521 is provided in the middle of the part of the adapter ring 52 for connecting to the lens 53, and the aperture of the second mounting hole 521 is set to be equal to the outer diameter of the lens 53; a fastening hole 514 is provided on the top surface of the connecting part, and the fastening hole 514 extends downward into the first mounting hole 513, and a fastening screw is provided in the fastening hole 514, and the fastening screw is tightened and squeezes the adapter ring 52, thereby fixing the adapter ring 52 in the first mounting hole 513.

[0084] The second mounting hole 521 and the lens 53 are fixed with high temperature resistant glue.

[0085] Furthermore, the adapter ring 52 is made of a high-temperature resistant and elastic rubber material, and the second mounting hole 521 can expand and contract within a certain range through the properties of rubber, thereby meeting the assembly needs of lenses 53 of different sizes. When the lens 53 is bonded to the second mounting hole 521 by glue, it is only necessary to remove the adapter ring 52 in the first mounting hole 513. The adapter ring 52 connected to lenses 53 of different sizes can be installed without replacing the fixing seat 51, thereby expanding the adaptability of the adjustable lens real-shot image jig to lenses 53 of different sizes and achieving cost reduction.

[0086] Example 3

[0087] See also Figures 1-6 , based on the above embodiment, another embodiment is provided.

[0088] The base 1, rotating table 2, rotating table 2, pendulum column 3, three-axis pan-tilt head 4, fixed seat 51, and fixed plate 61 are all made of high-temperature resistant steel after heat treatment, so that the overall structure has good adaptability to high-temperature environments and can be used normally in the high-temperature environment inside the car.

[0089] At the same time, the three-axis gimbal 4 uses a product in the existing technology that can record the displacement in the three-axis directions of X, Y, and Z, so as to accurately read the defocus data of the lens 53 after the lens 53 is offset, providing a reference basis for the quality of the lens 53, and facilitating the collection of data for subsequent improvements to the lens 53.
