Description

Technical Field

[0001] This utility model relates to the field of barrier gate capture technology, and in particular to a lens module adjustment device and a barrier gate capture integrated machine. Background Technology

[0002] With the rapid development of smart cities and intelligent traffic management systems, integrated barrier gate and image capture systems, combining automatic control, image capture, and license plate recognition, have become core equipment for vehicle access control. In practical applications, the installation environments of these systems vary widely. For example, the barrier gate itself may be laterally offset from the lane, or it may need to be compatible with both left-hand and right-hand traffic lanes. This necessitates that the built-in capture lens module possess high flexibility, capable of precisely adjusting its field of view to ensure stable and clear capture of vehicle information.

[0003] However, existing lens module adjustment solutions generally suffer from the following drawbacks: Firstly, the adjustment mechanism typically only supports rotational angle adjustment of the lens in directions such as pitch and pan, but cannot achieve translational displacement of the lens module in the horizontal direction. In extreme scenarios where there is a significant lateral offset between the barrier gate installation position and the lane centerline, relying solely on rotational angle adjustment is insufficient to effectively and completely cover the target capture area with the lens's field of view, thus limiting the application range of the equipment. Secondly, the locking structure of existing adjustment solutions is not reliable enough. When the barrier gate equipment operates outdoors for extended periods, exposed to wind, sun, and vibrations from opening and closing the gate arm, the lens angle is prone to slight shifts. Over time, this can lead to blurred captured images, decreased license plate recognition rates, or even complete misses, affecting the overall operational stability of the system.

[0034] Figure 1 This is a schematic diagram of the lens module adjustment device provided in this embodiment of the utility model. Figure 2 This is a schematic diagram of the rotating adjustment mechanism in the lens module adjustment device provided in this embodiment of the utility model. Figure 3 This is a cross-sectional view of the rotation adjustment mechanism in the lens module adjustment device provided in this embodiment of the utility model.

[0035] See Figures 1 to 3 This utility model provides a lens module adjustment device, which includes an adapter 10, a rotation adjustment mechanism 20, and a translation adjustment mechanism 30.

[0036] The adapter 10 is used to mount the lens module 300, which includes a lens body 310, a sensor plate 320, and a lens mount 330. The lens body 310 and the sensor plate 320 are mounted on the lens mount 330. In this embodiment, the adapter 10 can be a cup-shaped or semi-enclosed rectangular component. The adapter 10 has a standard interface, and the lens mount 330 of the lens module 300 can be screwed into the adapter 10 and fixed by corresponding threads or nuts. Of course, in other embodiments, the adapter 10 can also mount the lens module 300 by clamping, screw fastening, or other methods.

[0037] The rotation adjustment mechanism 20 is the core of the lens module 300 posture adjustment. The rotation adjustment mechanism 20 includes a connector 21, a support assembly 22, and a rotation adjustment knob 23. The connector 21 is preferably a rigid connecting rod. One end of the connector 21 has an integrally formed ball head 211 or a ball head 211 fixedly connected to it. The ball head 211 has a smooth spherical surface. The other end of the connector 21 is fixedly connected to the adapter 10. This fixed connection can be achieved by threading, welding, or integral forming. For example, the top of the connector 21 is threaded and can be fixed to the adapter 10 (sheet metal part) by a fastening nut 26 to ensure that the adapter 10 and the lens module 300 on it move synchronously with the connector 21.

[0038] The support assembly 22 supports and accommodates the ball head 211. Specifically, the support assembly 22 has a concave spherical surface for accommodating the ball head 211, which engages with the concave spherical surface to allow for automatic rotation. A rotary adjustment knob 23 is connected to the support assembly 22 and is used to apply or release pressure on the ball head 211 to lock or unlock it within the concave spherical surface. In this embodiment, the rotary adjustment knob 23 can be a handle screw or a finger screw. The rotary adjustment knob 23 passes through a threaded hole on the support assembly 22, and its end extends into the concave spherical surface and abuts against the surface of the ball head 211.

[0039] For example, during the unlocking operation: rotating the rotary adjustment knob 23 counterclockwise disengages the end of the rotary adjustment knob 23 from the ball head 211 or reduces the pressure. At this time, the friction between the ball head 211 and the concave spherical surface is very small, and the operator can easily rotate the adapter 10 to drive the ball head 211 to rotate freely within the concave spherical surface, thereby achieving the adjustment of the lens module 300's pitch, yaw, and tilt attitudes.

[0040] During the locking operation: After the lens module 300 is adjusted to the required posture, the adjustment knob 23 is tightened clockwise. The end of the adjustment knob 23 will apply a normal pressure to the ball head 211, so that a huge static friction force is generated between the ball head 211 and the inner wall of the concave spherical surface, thereby fixing the position of the ball head 211 firmly and completing the posture locking.

[0041] The translational adjustment mechanism 30 is fixedly connected to the support assembly 22. The translational adjustment mechanism 30 is used to drive the rotational adjustment mechanism 20 and the lens module 300 to perform translational position adjustment along a preset trajectory. That is, the translational adjustment mechanism 30 is used to achieve fine-tuning of the position of the entire lens module 300 in the plane. In this embodiment, the translational adjustment mechanism 30 may include a base 31 and a slider 32. The base 31 can serve as a lens cover. Adjusting the slider 32 to slide relative to the base 31 can drive the support assembly 22 and the entire rotational adjustment mechanism 20 and the lens module 300 connected thereto to perform translational position adjustment on the preset trajectory.

[0042] It should be noted that the translational adjustment mechanism 30 in the above embodiment is only an example, and it can also be any other mechanism capable of achieving translational position adjustment, such as a dovetail slide. In addition, the rotary adjustment knob 23 can also be a cam clamping mechanism, a hydraulic or pneumatic locking mechanism, etc., as long as it can apply or release pressure to the ball head 211.

[0043] It is understood that the lens module adjustment device 100 provided in this embodiment of the present invention includes an adapter 10, a rotation adjustment mechanism 20, and a translation adjustment mechanism 30. The connector 21 of the rotation adjustment mechanism 20 is fixedly connected to the adapter 10, and the translation adjustment mechanism 30 is fixedly connected to the support component 22 of the rotation adjustment mechanism 20. By integrating the translation adjustment and rotation adjustment functions, it is possible to achieve multi-degree-of-freedom adjustment of the position and orientation of the lens module 300, which is comprehensive in function and highly applicable.

[0044] By providing an independent adapter 10, different lens modules 300 with different specifications or interfaces can be easily replaced, giving the entire adjustment device good compatibility and versatility, and reducing the cost of redesigning the entire device to adapt to different lenses. At the same time, the lens module 300 is indirectly connected to the rotation adjustment mechanism 20 via the adapter 10. Compared to the lens module 300 being directly connected to the rotation adjustment mechanism 20, this prevents the lens from being subjected to long-term stress, which could lead to image defocusing.

[0045] Furthermore, the ball joint structure, which uses a ball joint 211 in conjunction with a concave spherical surface, enables flexible and smooth adjustment of the lens module 300 in multiple rotational degrees of freedom, such as pitch and yaw, in a simple and compact manner. The ball joint 211 is locked by applying pressure to it via the rotating adjustment knob 23, ensuring easy operation and reliable locking, thus guaranteeing the stability of the lens module 300 after adjustment and providing strong vibration resistance.

[0046] The translational adjustment mechanism 30 can drive the entire rotating part, including the lens module 300, to make linear displacement in a specific direction (such as the width direction), realizing macroscopic adjustment of the lens module 300's spatial position. Combining translational and rotational adjustments together achieves comprehensive adjustment of the position and orientation of the lens module 300. In extreme scenarios where the barrier gate's installation position has a large lateral offset from the lane centerline, the lens's field of view can be effectively and completely covered to capture the target area through position translation and rotation angle adjustment, thereby expanding the barrier gate's application range.

[0047] Continue reading Figure 2 and Figure 3 In some embodiments of this utility model, the support component 22 in the rotary adjustment mechanism 20 has both a connecting function and a accommodating function as a support structure. The support component 22 includes a support base 221 and a ball head sleeve 222.

[0048] The support base 221 has a support part 221-1 and a sleeve 221-2 that are interconnected. The support part 221-1 is connected to the translational adjustment mechanism 30 by screws or bolts. Therefore, the support base 221 is not a simple block, but a composite structure composed of two functional parts (support part 221-1 and sleeve 221-2). The support part 221-1 connects the entire rotary adjustment mechanism 20 and the translational adjustment mechanism 30, serving as the basis for force transmission and position fixation. The sleeve 221-2 is used for housing and positioning. The sleeve 221-2 is a hollow tubular or cylindrical structure, and its internal space is used for installing subsequent components. The sleeve 221-2 has a first opening 221-3 and a second opening 221-4 at both ends, providing channels for the assembly and operation of subsequent components.

[0049] The ball head sleeve 222 is located at the position of the first opening 221-3 and is nested with the sleeve 221-2. The interior of the ball head sleeve 222 has a concave spherical surface for accommodating the ball head 211. That is, the ball head sleeve 222 is installed (or embedded) into one end of the sleeve 221-2 as an independent part. The concave spherical surface formed inside the ball head sleeve 222 is a precisely machined concave spherical surface used to form a spherical pair with the ball head 211 on the connector 21, which is the key contact surface for realizing rotational movement.

[0050] Essentially, the concave spherical surface used to accommodate the ball head 211 is not directly machined on the support 221, but is achieved through a separate ball head sleeve 222. This design facilitates processing and manufacturing, allowing for high-precision spherical surface machining of the ball head sleeve 222 or the selection of wear-resistant materials before it is assembled into the sleeve 221-2.

[0051] The rotary adjustment knob 23 is located at the position of the second opening 221-4, meaning that the rotary adjustment knob 23 is installed and operated from the other end opposite to the ball head sleeve 222. The rotary adjustment knob 23 is threaded to the inner wall of the sleeve 221-2, indicating that the external thread of the rotary adjustment knob 23 (e.g., a plug or a screw with a handle) mates with the internal thread of the sleeve 221-2.

[0052] In other words, the pressure is applied by rotating the adjustment knob 23 through a threaded drive. By rotating the adjustment knob 23, the self-locking and mechanical properties of the thread can be used to make it translate along the axis of the sleeve 221-2, thereby applying or releasing pressure to the ball head 211 inside.

[0053] This embodiment utilizes threaded transmission to convert rotational motion into linear pressure, and achieves reliable locking of ball head 211 through friction. At the same time, the modular and split structural design simplifies manufacturing and assembly.

[0054] When the attitude of the lens module 300 needs to be adjusted, the operator loosens the rotary adjustment knob 23 located at the second opening 221-4 counterclockwise. Due to the threaded connection, the rotary adjustment knob 23 will retract outward, thereby relieving its pressure on the internal ball joint 211. At this time, the ball joint 211 is in a relaxed state within the concave spherical surface formed by the ball joint sleeve 222, with minimal friction. The operator can easily manipulate the connector 21 connected to the ball joint 211 by hand, enabling the lens module 300 to rotate smoothly and freely in three-dimensional space (pitch, yaw, tilt).

[0055] After the lens module 300 is adjusted to the target posture, the operator tightens the rotary adjustment knob 23 clockwise. The rotational torque is converted into a powerful axial thrust through the threaded joint. Rotating the adjustment knob 23 inward, it directly or through the intermediate pressure block (such as the elastic pressure block 25 described below) compresses the ball head 211. The compressed ball head 211 will press tightly against the concave spherical surface of the ball head sleeve 222. The static friction prevents the ball head 211 from sliding or rotating within the ball head sleeve 222, thus firmly locking its posture in the current position and achieving stable and reliable posture fixation.

[0056] Continue reading Figure 2 and Figure 3 In some embodiments of this utility model, the rotary adjustment mechanism 20 further includes a guide sleeve 24 and an elastic pressure block 25.

[0057] The guide sleeve 24 is located inside the ball head sleeve 222. The guide sleeve 24 can be understood as a bushing or inner tube built into the ball head sleeve 222. The outer wall of the guide sleeve 24 mates with the inner wall of the ball head sleeve 222 or the sleeve 221-2, and the inner wall of the guide sleeve 24 forms a hollow channel. The elastic pressure block 25 is located inside the guide sleeve 24. The guide sleeve 24 provides a stable working environment for the elastic pressure block 25, preventing the elastic pressure block 25 from bending laterally, eccentrically or buckling when under pressure, and ensuring that the force is transmitted along the preset axial direction.

[0058] The elastic pressure block 25 abuts against the end of the ball head 211 and the rotary adjustment knob 23. That is, the elastic pressure block 25 is sandwiched between the force-applying end (rotary adjustment knob 23) and the force-receiving end (ball head 211). The elastic pressure block 25 can be a rubber block or the like. It is the medium for transmitting the entire locking force and is used to convert the linear displacement of the rotary adjustment knob 23 into a controllable and continuous elastic pressure applied to the ball head 211.

[0059] It is understood that, based on the original ball head 211 locking structure, this embodiment of the invention constructs an elastic buffer locking system by introducing a guide sleeve 24 and an elastic pressure block 25. The elastic pressure block 25 is an elastic element that can wrap around the spherical surface of the ball head 211 according to its deformation. Compared to the adjustment knob 23 directly contacting the ball head 211, the elastic pressure block 25 provides a larger contact area for compressing the ball head 211, resulting in a stronger clamping force and more stable positioning. It also avoids deformation and damage caused by long-term direct contact pressure between the adjustment knob 23 and the ball head 211.

[0060] In rigid locking systems, excessive force applied by the operator can easily lead to damage to the threads, ball joint 211, or ball joint sleeve 222 due to stress concentration. The elastic pressure block 25 acts as an overload buffer. When the locking force reaches a certain level, the large reaction force of the elastic pressure block 25 provides force feedback to the operator, while simultaneously absorbing excess travel, effectively preventing permanent damage to core components caused by excessive operation.

[0061] Furthermore, the elastic pressure block 25 can continuously provide a dynamic clamping force. Even when equipment vibration or thermal expansion and contraction causes slight displacement, the elastic pressure block 25 can automatically compensate for these changes, always maintaining effective pressure on the ball head 211, ensuring long-term stable and reliable attitude locking.

[0062] Continue reading Figure 3 In some embodiments of this utility model, the outer surface of the rotary adjustment knob 23 is provided with a rotor 231, a first step 232 and a second step 233 in sequence along its own axial direction. By defining the overall outline of the rotary adjustment knob 23, it can be understood that the rotary adjustment knob 23 is not a cylinder, but a stepped shaft structure with multiple different diameters.

[0063] The rotor 231 is located on the outside of the sleeve 221-2 and is a part for user hand operation; it can be a handle or a protrusion. The mounting position of the rotor 231 is always exposed outside the main structure (sleeve 221-2), ensuring that the user can operate it conveniently at any time.

[0064] The first step 232 and the second step 233 refer to the two annular shoulders formed by the change in diameter on the shaft. These steps not only serve as a structural division of areas but also provide a reference surface for the axial positioning of other components. The rotary adjustment knob 23 between the first step 232 and the second step 233 has an external thread that connects to the inner wall thread of the sleeve 221-2. That is, the external thread does not cover the entire rotary adjustment knob 23 but is limited to the area between the first step 232 and the second step 233, making the movement stroke of the rotary adjustment knob 23 controllable.

[0065] A top post 234 is formed between the second step 233 and the end of the rotary adjustment knob 23. The top post 234 is adapted to move along the guide sleeve 24 to compress the elastic block 25 or release the pressure on the elastic block 25. In other words, the final actuating part for performing the pressurization or depressurization action is the top post 234, which is a columnar portion extending from the second step 233 to the end of the adjustment member. That is, the top post 234 acts as a piston or push rod, reciprocating axially under the guidance of the guide sleeve 24, directly interacting with the elastic block 25 to achieve force transmission.

[0066] It should be noted that a buffer 27 is provided at the position of the second step 233. The buffer 27 is adapted to abut against the guide sleeve 24. That is, a buffer 27 is provided at the shoulder position of the second step 233. The function of the buffer 27 is to abut against the end face of the guide sleeve 24 when the rotary adjustment knob 23 is rotated to the limit position, and absorb kinetic energy by elastic deformation, so that the rotary adjustment knob 23 can stop smoothly when it reaches the maximum stroke, rather than a rigid metal impact.

[0067] The buffer 27 is typically made of elastic materials such as rubber, silicone, or polyurethane, for example, an O-ring or an elastic pad.

[0068] When the user rotates the adjustment knob 23 outwards, the top post 234 retracts from the elastic block 25, and the buffer 27 on the second step 233 contacts the end face of the guide sleeve 24 before any other rigid component, thereby absorbing kinetic energy through elastic deformation, so that the adjustment component can stop smoothly when it reaches its maximum stroke, rather than with a rigid metal impact.

[0069] In addition, the buffer 27 (such as an O-ring) can also play a certain sealing role after contact, preventing dust, moisture and other contaminants from entering the ball head 211 and elastic pressure block 25 through the gap between the rotary adjustment knob 23 and the guide sleeve 24, ensuring the long-term smoothness and cleanliness of the universal structure.

[0070] Continue reading Figure 1 and Figure 4 In some embodiments of this utility model, the translational adjustment mechanism 30 includes a base 31, a sliding member 32, and a translational adjustment knob 33.

[0071] The base 31 is used for mounting to the front panel of the housing 200, such as on the panel of an equipment chassis. The base 31 serves as both a protective housing for the lens and a fixed base for the entire adjustment device. The sliding member 32 is provided on the base 31 and moves relative to the base 31.

[0072] The base 31 is provided with a guide member 311, that is, a guiding component is integrated on the base 31. The guide member 311 can be a raised slider, a cylindrical guide pin, a pin, or any form of linear raised structure. The sliding member 32 is provided with a groove 321 that mates with the guide member 311.

[0073] Alternatively, the guide member 311 can also be disposed on the slider 32, and the slide groove 321 can also be disposed on the base 31. That is, either the base 31 or the slider 32 has a guide member 311, and the other has a slide groove 321. The guide member 311 and the slide groove 321 slide in cooperation, forming a kinematic pair to limit the trajectory of translational position adjustment and ensure the determinacy and stability of the movement. In other words, the guide member 311 slides in the slide groove 321, forming a guide rail and slider cooperation mode, which limits the trajectory of translational adjustment. This trajectory can be a straight line (achieving single-axis translation), and the shape of the trajectory is determined by the shape of the guide member 311 and the slide groove 321.

[0074] The translational adjustment knob 33 is located on the slider 32 and selectively connects to the base 31. This selective connection does not mean permanent fixation, but rather an action that can be applied and disengaged. For example, the translational adjustment knob 33 can be a screw passing through the slider 32. When tightened, its end can press against the base 31, achieving connection (i.e., locking) through friction; when loosened, the pressing is released, achieving disconnection (i.e., unlocking). Alternatively, when tightened, its end is threadedly connected to the base 31, and when loosened, it will not fall off the slider 32.

[0075] The rotation adjustment mechanism 20 is mounted on the sliding member 32 by screws. The sliding member 32 is provided with a waist-shaped window 324, and the lens module 300 is located in the waist-shaped window 324.

[0076] When the translation adjustment knob 33 is released, the operator can apply external force to make the slider 32 and the entire lens module 300 thereon slide along the trajectory set in the guide 311 in the slide groove 321, thereby adjusting the position.

[0077] Once the adjustment is complete, the operator tightens the translation adjustment knob 33 to apply a locking force to the base 31, thereby locking the slider 32 in the current position.

[0078] It is understood that this utility model embodiment abandons the external, bulky general translation stage and integrates the translation adjustment mechanism 30 completely into the lens cover of the product, so that the final product has a simple appearance, compact structure and no redundant parts.

[0079] In some embodiments of this utility model, the guide member 311 has a connecting section, a guide section, and a limiting end connected in sequence. The connecting section is fixedly connected to the base 31 and serves as the sliding block of the slider 32. The guide section slides in conjunction with the slide groove 321, and the limiting end is engaged with the outer wall of the slide groove 321, indicating that the function of the limiting end is to prevent the slider 32 from falling off the translational adjustment knob 33.

[0080] The cross-sectional dimension of the limiting end is larger than that of the guide section, and the length of the guide section is greater than the depth of the slide groove 321. The cross-sectional dimension of the guide section is smaller than that of the slide groove 321, which ensures that the sliding member 32 has sufficient and smooth sliding space on the guide section and will not get stuck.

[0081] In this embodiment of the utility model, the guide 311 is an I-shaped pin. The head of the I-shaped pin has a large diameter and the middle part has a small diameter, which can not only guide but also prevent it from coming out.

[0082] A circular positioning hole is provided in the middle of the slide groove 321. The diameter of the positioning hole is larger than the width of the slide groove 321. The size of the limiting end is adapted to the size of the positioning hole, that is, the diameter of the limiting end is larger than the diameter of the head of the I-shaped pin, so that the I-shaped pin can be inserted. In other words, the limiting end of the guide member 311 can only pass through this positioning hole and cannot pass through any other part of the slide groove 321.

[0083] The slide groove 321 is a racetrack-shaped track symmetrically arranged on the left and right sides with the circular positioning hole as the center. The width of the slide groove 321 is 0.2mm larger than the diameter of the middle part of the I-shaped pin, and much smaller than the diameter of the head of the I-shaped pin. In addition, the wall thickness of the sliding part 32 is also smaller than the height of the middle part of the I-shaped pin. This clearance fit can achieve smooth sliding and prevent the slider from falling out.

[0084] During assembly (insertion): Move the slider 32 to a specific position so that its positioning hole aligns with the limiting end of the guide 311. At this time, pass the limiting end through the positioning hole on the slider 32.

[0085] During adjustment (sliding): The slider 32 is moved horizontally along the slide groove 321. At this time, the guide section of the guide member 311 enters the narrow part of the slide groove 321, while its limiting end is stuck on the outer wall of the slide groove 321 and cannot be dislodged. In this state, the slider 32 can only adjust its position by moving along the trajectory specified by the guide section.

[0086] When disassembling (pulling out): reverse the operation and move the slider 32 back to its initial position, that is, the position of the positioning hole, so that the positioning hole is aligned with the limit end again, and the two can be easily separated.

[0087] This invention enables rapid assembly and disassembly without any tools. The entire process requires only three steps: alignment, insertion, and translation, which improves production efficiency and the convenience of on-site installation and debugging, while reducing the skill requirements for operators.

[0088] Compared to traditional adjustment and locking mechanisms that require screws, nuts, or lead screws, this utility model integrates guiding, limiting, and quick-release functions into two simple parts, significantly reducing the number of parts and thus lowering manufacturing costs and failure rates.

[0089] In some embodiments of this utility model, the translational adjustment knob 33 includes at least four lock-up screws, which typically have a head or tail structure that cannot pass through the mounting hole, and a smooth rod that allows it to remain attached to the panel on which it is mounted after being loosened without falling off.

[0090] At least four lock screws are divided into two groups. One group is used to lock the position of the slider 32 in the positive direction of movement, and the other group is used to lock the position of the slider 32 in the negative direction of movement. The length of the center line of all lock screws in each group is equal to half the length of the groove 321. When each group includes two lock screws, the distance between the center lines of the two lock screws is equal to half the length of the groove 321, that is, the length of the groove 321 is the total stroke length that the slider 32 can move.

[0091] When the position of the slider 32 needs to be adjusted, loosen all the captive screws. Because the captive screws are designed to be secure, they will not fall out. Then, slide the slider 32 along the groove 321.

[0092] When the slider 32 is slid to the end of the groove 321, the two captive screws are aligned and can be screwed into the locking hole 312 (threaded hole) on the base 31, and the slider 32 is securely locked.

[0093] This configuration, where the distance between the centerlines of the two self-locking screws is equal to half the length of the slide groove 321, allows for complete coverage of the entire length of the slide groove 321's travel and locking at critical points. Unlike continuous adjustment relying on friction, the positioning in this embodiment is based on precise hole positions. Each lock returns to the exact same position, achieving repeatable precision positioning. Furthermore, using self-locking screws fundamentally eliminates equipment malfunctions or production delays caused by screws falling or being lost during installation or maintenance, making it particularly suitable for complex environments or confined spaces.

[0094] It should be noted that symmetrical protrusions 323 are provided on both sides of the slider 32, and the captive screw is installed on the protrusions 323. That is, the slider 32 is raised at the installation position of the captive screw to ensure that when the slider 32 is adjusted horizontally, the end of the captive screw will not interfere with the plane of the base 31 in front, so that the adjustment movement is smooth.

[0095] Continue reading Figure 1In some embodiments of this utility model, the sliding member 32 is a moving platform that supports the entire rotation adjustment mechanism 20. A limiting member 322 is provided on the sliding member 32 to restrict the movement of the rotation adjustment mechanism 20. The limiting member 322 can be an integrally formed protrusion or a separately installed part. The limiting member 322 has a U-shaped slot 322-1, which is used to engage the connecting member 21. Therefore, the purpose of the slot 322-1 is to accommodate and constrain the connecting member 21, thereby limiting the rotation range of the connecting member 21.

[0096] In this embodiment of the utility model, the movement range of the connector 21 is limited by setting a groove 322-1 on the sliding member 32. On the one hand, it can prevent the lens module 300 from tilting downward at too large an angle, which could cause the lens to hit the front window 260. On the other hand, it can limit the rotation adjustment mechanism 20 from rotating, because this angular rotation is meaningless for the lens capture of the barrier gate integrated machine, and may even cause the live image to tilt.

[0097] After the clubhead 211 is unlocked, the connector 21 rotates downwards under the influence of gravity or external force until its shaft hits and abuts against the front face of the "U"-shaped slot 322-1. At this point, the connector 21 can no longer rotate downwards. Since the position and size of the "U"-shaped slot 322-1 are fixed, the angle at which the connector 21 abuts against the front face is exactly the same each time. This angle is the preset default overhead angle, which is approximately 10°.

[0098] When the lens module 300 needs to be rotated, the rotor 231 of the rotation adjustment knob 23 is manually rotated counterclockwise. The rotation adjustment knob 23 moves backward, and the front top column 234 no longer acts on the elastic pressure block 25. As a result, the clamping force on the ball head 211 disappears, and the ball head 211 can rotate. The rotation angle of the lens module 300 can then be adjusted according to actual needs. For example, the capture lens of the barrier gate is generally located at the top of the equipment in the height direction. To capture the license plate information of vehicles at a lower height, the lens needs to be tilted downward. This can be achieved by moving the ball head 211, so that the connector 21 and its integrated adapter 10 move around the axis with the lens module 300, thereby changing the pitch angle and adjusting the lens field of view downward to cover the capture scene requirements.

[0099] After the rotation angle of the lens module 300 is adjusted, manually rotate the rotor 231 of the rotation adjustment knob 23 clockwise. As the rotation adjustment knob 23 moves forward, the front top post 234 will gradually contact and act on the elastic pressure block 25, and drive the ball head 211 forward. If the rotation continues, the elastic pressure block 25 will be compressed, and the ball head 211 will abut against the spherical surface of the ball head sleeve 222, and be held and fixed by the compression of the ball head sleeve 222 and the elastic pressure block 25.

Figure 5 This is an isometric sectional view of the housing of the integrated gate and camera capture machine provided in this embodiment of the utility model. Figure 6 yes Figure 5 Enlarged view of part A in the middle. Figure 7 This is a schematic diagram of the lens module in the barrier gate capture integrated machine provided in this embodiment of the utility model moving to its limit position. Figure 8 yes Figure 7 Enlarged view of section B in the middle.

[0101] See Figures 4 to 8 This utility model embodiment also provides a barrier gate capture integrated machine, which includes a housing 200 and a lens module 300 disposed in the housing 200; and a lens module adjustment device 100 including any of the above embodiments.

[0102] The housing 200 has a front panel 210 and a rear panel 220 arranged opposite to each other. The translational adjustment mechanism 30 in the lens module adjustment device 100 is fixedly installed on the front panel 210, and the rear panel 220 has an adjustment window 230. Both the rotational adjustment mechanism 20 and the translational adjustment mechanism 30 are arranged to be adjusted through the adjustment window 230.

[0103] Furthermore, a removable rear cover plate 240 is provided at the adjustment window 230, and a seal 250 is provided between the rear cover plate 240 and the rear panel 220 to ensure the waterproof sealing effect inside the integrated barrier gate device. The seal 250 is adhesively attached to the rear panel 220 of the housing 200, so even if the rear cover plate 240 is temporarily removed for lens adjustment, the seal 250 will not fall off.

[0104] Adjusting the existing lens module 300 often requires disassembling the entire housing 200 and using specialized tools such as screwdrivers. This process is not only cumbersome and time-consuming, but also exposes the delicate internal components to dust and moisture when operating outdoors, affecting the efficiency and convenience of installation, deployment, and subsequent maintenance.

[0105] The barrier gate capture device provided in this embodiment does not require opening the entire housing 200, and the entire adjustment operation does not require any external devices or tools. The debugging solution is convenient, efficient, and easy to use.

[0106] The following describes the adjustment scheme for adapting to the actual application scenario of the barrier gate capture device provided in this embodiment of the present invention.

[0107] During the production and assembly stage of the barrier gate capture machine, the lens module 300 is located in the middle position in the waist-shaped window 324 of the sliding member 32, that is, the guide member 311 (I-shaped pin) of the base 31 is located in the center of the sliding groove 321 on the sliding member 32.

[0108] When the integrated gate and camera capture device is used in specific application scenarios such as vehicle entrances and exits, the lens module 300 will be adjusted to the left or right limit position according to the working direction of the gate arm, and rotated by a certain angle so that the lens field of view covers the capture environment.

[0109] During the equipment manufacturing and assembly stage, the rotary adjustment mechanism 20 is fixed to the adapter 10 by the fastening nut 26, and then fixed to the L-shaped bending surface of the sliding member 32. Two screws pass through the opening on the L-shaped bending surface of the sliding member 32 to lock the support base 221. The lens falls in the waist-shaped window 324 of the sliding member 32, and the connector 21 is embedded in the slot 322-1 of the sliding member 32. Manually loosen the rotary adjustment knob 23, the clamping force of the ball head 211 disappears and it can rotate. Rotate the connector 21 downward until it abuts the front end face of the slot 322-1, and the lens tilts downward at a certain default downward angle (about 10°). The positioning hole of the sliding member 32 is engaged with the I-shaped pin of the base 31, and then the four non-removable screws are manually tightened. The sliding member 32 and the base 31 are then fixed into an integral structure. Finally, the base 31 is fixed to the front panel 210 of the gate integrated machine housing 200 using the stud and nut locking assembly. Thus, the camera focuses on the center of the external viewing window 260, where the integrated barrier gate's housing 200 is closed, locked, and shipped to the equipment application scenario.

[0110] After the integrated barrier gate camera is manufactured and assembled, and the housing 200 is covered, subsequent adjustments to the lens module 300 do not require opening the housing 200 for debugging. Adjustments can be made via the adjustment window 230 on the rear panel 220 of the housing 200. This method eliminates the need to move the front panel 210 and viewing window 260, allowing for online adjustment of the lens angle and position based on real-time captured images, resulting in high accuracy and convenience. The adjustment window 230 on the rear panel 220 of the housing 200 is positioned directly above the lens module adjustment device. A rear cover plate 240 is provided on the adjustment window 230 for easy and quick disassembly and installation.

[0111] When lens adjustment is needed, reach into the adjustment window 230 and manually loosen or tighten the rotor 231 of the adjustment knob 23 and the non-removable screw on the slider 32 to adjust and fix the lens rotation angle and translation position. All adjustment parts are oriented towards the rear cover 240, making operation simple and efficient. No external devices or tools are required, and the components of the adjustment assembly will not fall off, making the adjustment action highly user-friendly.

[0112] After the integrated barrier gate camera is deployed in a real-world scenario, the position of the lens module 300 needs to be adjusted on-site according to the vehicle entrance / exit location and the working direction of the barrier arm. For example, if the integrated barrier gate is adapted to a right-hand barrier arm, the lens module 300 needs to be moved away from the barrier arm and rotated so that the lens faces the barrier arm to capture the license plate information of the vehicles entering and exiting. The specific operation is as follows: open the rear cover 240 of the housing 200, manually loosen the four non-removable screws on the sliding member 32, and then the sliding member 32 moves the lens module 300 towards the barrier arm. Figure 1 The positive translational sliding in the width direction is shown until... Figure 8 The extreme position shown is where the I-shaped pin falls on the leftmost side of the slide groove 321.

[0113] After the translational adjustment is complete, manually tighten the two captive screws. Once in place, manually rotate the rotor 231 of the rotary adjustment knob 23 counterclockwise. The clamping force of the ball head 211 will disappear, allowing it to rotate freely. Compare this to the real-time shooting scene and rotate the connector 21 towards the rod side at a certain angle until the lens field of view can capture the required range of the scene without obstruction or vignetting. After adjustment, manually rotate the rotor 231 of the rotary adjustment knob 23 clockwise. The top post 234 at the front of the rotary adjustment knob 23 and the elastic pressure block 25 clamp the ball head 211, thus completely fixing the position of the lens. Since the spacing between the two captive screws in each group is equal to half the length of the slide groove 321, when the lens module 300 is translatably slid to its limit position, two captive screws can be effectively fixed.

[0114] After the lens position is adjusted, the rear cover plate 240 is then installed onto the rear panel 220 of the housing 200. The final position of the lens on the barrier gate's integrated camera is as follows: Figure 5 and Figure 6 As shown, the lens is positioned away from the gate arm and angled towards it. This serves two purposes: firstly, it compensates for the lens's field of view, meeting coverage requirements in extreme scenarios; secondly, it ensures that the lens's optical path is not obstructed by internal components, mitigating the risk of vignetting. Furthermore, while the integrated gate's lens operates to one side, the unused area of ​​the other side's viewing window 260 can be shielded using the area of ​​the sliding component 32, effectively concealing internal parts and wiring, thus contributing to an aesthetically pleasing appearance.

[0115] It is understood that the barrier gate capture integrated machine provided in this utility model embodiment can not only realize the adjustment of any rotation angle, but also support the translational adjustment of the left and right positions to adapt to the operation of the left and right side gate arms at different positions, and meet the scene coverage requirements of the lens capture field of view; at the same time, the lens adjustment action meets the ease of use requirements, realizes real-time online scene adjustment, and the debugging operation is simple and efficient, realizing the adaptation adjustment of angle and position without the aid of any tools.

[0116] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
