[0002] Currently, camera technology is widely and maturely applied. In the field of optical imaging, the precision and efficiency of lens adjustment fixtures directly affect image quality, especially in scenarios such as automotive and industrial inspection. Traditional lens adjustment fixtures often suffer from unstable image quality due to their complex structure and insufficient adjustment precision.
[0003] Existing technologies use manual knobs or separate adjustment components, which have problems such as cumbersome operation and poor adaptability. Utility Model Content
[0004] The main purpose of this invention is to provide a fixture for quickly adjusting lens imaging, which aims to save time and cost of returning the lens for repair by removing the protective glass mount without disassembling the entire lens.
[0005] To achieve the above objectives, the present invention proposes a fixture for quickly adjusting lens imaging, comprising:
[0006] The base is arranged in a ring shape, and the inner side of the base is stepped to form a first segment and a second segment with the inner diameter increasing sequentially from front to back.
[0007] An adjusting cylinder is movably disposed on the base in the front-rear direction, and at least a portion of it can extend out of the rear end of the base. A protrusion is formed at the front end of the adjusting cylinder in the radial direction of the adjusting cylinder.
[0008] A compression spring is sleeved on the outside of the adjusting cylinder, and one end of the compression spring in the front-back direction abuts against the portion of the first section that protrudes from the second section, while at least a portion of the other end is disposed inside the protrusion of the adjusting cylinder;
[0009] The imaging component abuts against the front end of the regulating cylinder;
[0010] A lens assembly, including a lens barrel, is disposed on the front side of the base and detachably connected to the base along the front-rear direction; and,
[0011] An adjustment ring is rotatably connected to the portion of the adjustment cylinder extending from the rear end of the base, used to release or compress the compression spring during the rotation of the adjustment ring, thereby driving the adjustment cylinder and the imaging assembly to move in the front-back direction to complete zooming.
[0012] In one embodiment, a groove is formed on the front end face of the adjusting cylinder;
[0013] The imaging component includes:
[0014] An imaging harness is disposed within the groove; and,
[0015] An imaging chip is disposed at the front end of the imaging harness and electrically connected to the imaging harness, for converting the light signal focused by the lens into an electrical signal.
[0016] In one embodiment, the portion of the adjusting cylinder extending beyond the rear end of the base is provided with external threads for threaded connection of the adjusting ring.
[0017] In one embodiment, the base further includes a third segment whose inner diameter increases sequentially from front to back, and the front end of the third segment is open;
[0018] The fixture for quickly adjusting lens imaging also includes an adjustment and fixing fixture, which is detachably connected to the third section. The front end face of the adjustment and fixing fixture has a connecting hole for connecting lens barrels of different shapes.
[0019] In one embodiment, a sealing groove is recessed on the peripheral side of the rear end of the lens barrel, and an O-ring is provided in the sealing groove to seal with the protective glass seat.
[0020] In one embodiment, the front end of the inner side of the base is stepped to form a rearwardly facing abutting surface, and at least a portion of the front end of the imaging component abuts against the abutting surface;
[0021] The fixture for quickly adjusting lens imaging also includes a pressure ring, which is disposed inside the base and located at the rear end of the base. The front end of the pressure ring abuts against the rear end of the imaging component to press the imaging component onto the base.
[0022] In one embodiment, the outer surface of the adjustment ring is provided with an anti-slip texture.
[0023] In one embodiment, a scale is provided on the portion of the adjusting cylinder extending beyond the rear end of the base.
[0024] In one embodiment, a lighting device is also provided inside the cavity.
[0025] This utility model also proposes a vehicle-mounted lens, including a fixture for quickly adjusting lens imaging, wherein the fixture for quickly adjusting lens imaging includes:
[0026] The base is arranged in a ring shape, and the inner side of the base is stepped to form a first segment and a second segment with the inner diameter increasing sequentially from front to back.
[0027] An adjusting cylinder is movably disposed on the base in the front-rear direction, and at least a portion of it can extend out of the rear end of the base. A protrusion is formed at the front end of the adjusting cylinder in the radial direction of the adjusting cylinder.
[0028] A compression spring is sleeved on the outside of the adjusting cylinder, and one end of the compression spring in the front-back direction abuts against the portion of the first section that protrudes from the second section, while at least a portion of the other end is disposed inside the protrusion of the adjusting cylinder;
[0029] The imaging component abuts against the front end of the regulating cylinder;
[0030] A lens assembly, including a lens barrel, is disposed on the front side of the base and detachably connected to the base along the front-rear direction; and,
[0031] An adjustment ring is rotatably connected to the portion of the adjustment cylinder extending from the rear end of the base, used to release or compress the compression spring during the rotation of the adjustment ring, thereby driving the adjustment cylinder and the imaging assembly to move in the front-back direction to complete zooming.
[0032] In this invention, when adjusting to short focal length imaging (i.e., wide-angle), the operator releases the compression spring by rotating the adjustment ring, thereby driving the adjustment cylinder and the imaging component to move forward. The distance between the imaging component and the lens assembly decreases, and the imaging component acquires the image focused by the lens assembly, converting the image's light signal into an electrical signal and transmitting it to the vehicle system. The operator observes the image's clarity to determine if the lens is in the optimal imaging position. When the optimal imaging effect is achieved, the operator stops rotating the adjustment ring, completing the focusing process. When adjusting to long focal length imaging (i.e., telephoto), the operator releases the compression spring by rotating the adjustment ring, again observing the image's clarity to determine if the lens is in the optimal imaging position. When the optimal imaging effect is achieved, the operator stops rotating the adjustment ring, completing the focusing process. Thus, by rotating the adjustment ring to compress or release the compression spring, the lens can be adjusted for both long and short focal lengths. The operation is simple, enabling rapid and precise forward and backward adjustment of the lens. Attached Figure Description

[0042] This utility model proposes a fixture 100 for quickly adjusting lens imaging.
[0043] Please see Figure 1In one embodiment of this utility model, the quick-adjustment lens imaging fixture 100 is characterized by comprising a base 1, an adjusting cylinder 2, a compression spring 3, an imaging assembly 4, a lens barrel 51, and an adjusting ring 6: the base 1 is annularly arranged, and the inner surface of the base 1 is stepped to form a first section 11 and a second section 12 with the inner diameter increasing sequentially in the front-to-back direction; the adjusting cylinder 2 is movably disposed on the base 1 in the front-to-back direction, and at least a portion of it can extend out of the rear end of the base 1, and the front end of the adjusting cylinder 2 has a protrusion 21 formed radially along the adjusting cylinder 2; the compression spring 3 is sleeved on the outside of the adjusting cylinder 2, and the... One end of the compression spring 3 in the front-back direction abuts against the portion of the first segment 11 that protrudes from the second segment 12, and at least a portion of the other end is disposed within the protrusion 21 of the adjusting cylinder 2; the imaging assembly 4 abuts against the front end of the adjusting cylinder 2; the lens barrel 51 is disposed on the front side of the base 1 and is detachably connected to the base 1 in the front-back direction; the adjusting ring 6 is rotatably connected to the portion of the adjusting cylinder 2 that extends out of the rear end of the base 1, so as to release or compress the compression spring 3 during the rotation of the adjusting ring 6, thereby driving the adjusting cylinder 2 and the imaging assembly 4 to move in the front-back direction to complete focusing.
[0044] Understandably, when the lens moves upward, the distance between the lens barrel 51 and the imaging component 4 increases, which is suitable for long focal length imaging; when the lens moves downward, the distance between the lens barrel 51 and the imaging component 4 decreases, which is suitable for short focal length imaging.
[0045] Furthermore, this utility model does not limit the connection method between the lens barrel 51 and the base 1. The lens barrel 51 can be connected to the base 1 by thread or by magnetic attraction. The lens assembly 5 includes the lens barrel 51 and the lens inside the lens barrel 51. This utility model does not limit the specific shape, number and optical power of the lens inside the lens barrel 51, and can be adjusted according to actual needs.
[0046] In this invention, when adjusting to short focal length imaging (i.e., wide-angle), the operator releases the compression spring 3 by rotating the adjustment ring 6, thereby driving the adjustment cylinder 2 and the imaging component 4 to move forward. The distance between the imaging component 4 and the lens assembly 5 decreases. The imaging component 4 acquires the image focused by the lens assembly 5, converts the light signal of the image into an electrical signal, and transmits it to the vehicle system. The operator judges whether the lens is in the optimal imaging position by observing the image clarity. When the optimal imaging effect is achieved, the operator stops rotating the adjustment ring 6, completing the focusing process. When adjusting to long focal length imaging (i.e., telephoto), the operator releases the compression spring 3 by rotating the adjustment ring 6, and similarly judges whether the lens is in the optimal imaging position by observing the image clarity. When the optimal imaging effect is achieved, the operator stops rotating the adjustment ring 6, completing the focusing process. Thus, by rotating the adjustment ring 6 to compress or release the compression spring 3, the long and short focal length adjustments of the lens can be completed. The operation is simple, enabling rapid and precise adjustment of the lens in both forward and backward directions.
[0047] Specifically, in one embodiment of this utility model, a groove is formed on the front end face of the adjusting cylinder 2. The imaging component 4 includes an imaging harness 41 and an imaging chip 42. The imaging harness 41 is disposed in the groove; the imaging chip 42 is disposed at the front end of the imaging harness 41 and electrically connected to the imaging harness 41 to convert the light signal focused by the lens into an electrical signal. By setting the groove design, the imaging component 4 is aligned with the optical axis of the lens barrel 51, reducing signal transmission errors. The imaging harness 41 is used to transmit the electrical signal of the imaging chip 42 to the vehicle system so that the staff can observe the imaging effect. Specifically, the imaging harness 41 can be embedded in the groove and fixed with flexible adhesive, and the imaging chip 42 is fixed to the front end of the harness with a micro screw.
[0048] It should be noted that the common lens barrel 51 is generally square or round. To accommodate different shapes of lens barrel 51, in one embodiment of this utility model, the base 1 further includes a third segment 13 with an increasing inner diameter from front to back, and the front end of the third segment 13 is open. The quick-adjustment lens imaging fixture 100 also includes an adjustment and fixing fixture 7, which is detachably connected to the third segment 13. The front end face of the adjustment and fixing fixture 7 has a connecting hole for connecting lens barrels 51 of different shapes. It is understood that this utility model does not limit the specific shape of the connecting hole. When a square lens barrel 51 needs to be connected, the connecting hole can be set to square; when a round lens barrel 51 needs to be connected, the connecting hole can be set to round. In addition, this utility model does not limit the connection method between the lens barrel 51 and the adjustment and fixing fixture 7. The lens barrel 51 can be connected to the adjustment and fixing fixture 7 by thread or by magnetic attraction.
[0049] It is understandable that, since the base 1 is detachably connected to the lens barrel 51, and the imaging assembly 4 and the lenses inside the lens barrel 51 are very sensitive to dust, particles, and other contaminants, if the sealing is poor, these contaminants will adhere to the optical surface, affecting image quality and causing blurry or spotted images. Therefore, in one embodiment of this invention, a sealing groove is recessed on the peripheral side of the rear end of the lens barrel 51, and an O-ring is provided in the sealing groove for a sealing fit with the base 1. Specifically, the depth and width of the sealing groove should match the O-ring to ensure that the O-ring can be properly compressed after installation, thereby providing a good sealing effect through an interference fit within the sealing groove. Furthermore, when the adjusting and fixing fixture 7 is threadedly connected to the lens barrel 51, it is understood that the sealing performance of the threaded connection is usually insufficient to meet stringent sealing requirements. Similarly, a sealing groove can be recessed at the external thread at the rear end of the lens barrel 51, and an O-ring can be provided in the sealing groove to improve the sealing performance.
[0050] To better secure the imaging component 4, in one embodiment of this invention, the front end of the inner side of the base 1 is stepped to form a rearward-facing abutting surface. At least a portion of the front end of the imaging component 4 abuts against this abutting surface. The quick-adjustment lens imaging fixture 100 also includes a pressure ring, which is located inside the base 1 and at the rear end of the base 1. The front end of the pressure ring abuts against the rear end of the imaging component 4 to press the imaging component 4 firmly onto the base 1. By setting the abutting surface and the pressure ring, the imaging component 4 is pressed firmly at both the front and rear ends, preventing the imaging component 4 from shaking and affecting the imaging effect, ensuring that the imaging chip 42 is aligned with the optical center of the lens barrel 51, and reducing imaging distortion.
[0051] To facilitate manual operation, in one embodiment of this invention, the outer surface of the adjusting ring 6 is provided with an anti-slip texture, thereby improving the accuracy and efficiency of the operator during adjustment. Specifically, in one embodiment, the outer surface of the adjusting ring 6 is provided with a diamond-shaped or wavy anti-slip texture, with a texture depth of 0.3-0.5mm, and the material is hard anodized aluminum, which can effectively increase the friction effect.
[0052] To further improve accuracy, in one embodiment of this utility model, the portion of the adjusting cylinder 2 extending from the rear end of the base 1 is provided with a scale, which facilitates the operator to quantify the adjustment stroke and quickly locate the optimal imaging focus.
[0053] Furthermore, it is understandable that in low-light conditions such as at night, the imaging effect is poor, making it difficult for staff to determine whether they are in the optimal imaging position. Therefore, in one embodiment of this utility model, an illumination device is also provided inside the cavity to assist imaging under low-light conditions and improve image clarity. Specifically, an LED light strip with a color temperature of 5000-6000K can be embedded inside the base 1, which evenly illuminates the front of the lens barrel 51 through a light guide plate, increasing illumination without affecting the imaging effect due to the color temperature.
[0054] This utility model also proposes a vehicle-mounted lens, which includes a fixture for quickly adjusting the lens imaging. The specific structure of the fixture for quickly adjusting the lens imaging is as described in the above embodiments. Since this fixture for quickly adjusting the lens imaging adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
[0055] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
