Description

Technical Field

[0001] This utility model relates to the technical field of facial recognition device frames, specifically a facial recognition device frame with an adjustable installation angle. Background Technology

[0002] With the rapid development of artificial intelligence technology, facial recognition devices are widely used in security, access control, smart terminals and other fields. Due to the diversity of usage scenarios, such as different heights of installation walls, different tilt angles of door frames, and complex indoor and outdoor lighting environments, higher requirements are placed on the adjustment flexibility of the installation frame of facial recognition devices.

[0003] Existing facial recognition devices generally suffer from fixed installation angles or limited adjustment ranges in their outer frames. Traditional structures often employ fixed brackets or simple hinged structures, allowing only minor angle adjustments in a single direction. This makes it difficult to simultaneously meet the multi-dimensional adjustment needs of height, horizontal position, tilt angle, and horizontal rotation angle. When the device needs to be installed on non-horizontal walls such as stair corners, existing frames cannot flexibly adjust to maintain the optimal alignment angle of the recognition lens. Furthermore, it is difficult to ensure recognition efficiency through convenient height adjustments for users of different heights. In addition, some adjustable frames have complex structures, require tools for adjustment, and lack stability, making them prone to loosening and shifting over time, leading to a decrease in recognition accuracy.

[0015] (III) Beneficial Effects

[0016] This utility model provides a face recognition device frame with a flexibly adjustable installation angle, which has the following advantages:

[0017] The adjustable-angle facial recognition device frame, through the cooperation of support rods and support sleeves, can slide up and down under force, changing the distance the support rods extend within the support sleeves. This adjusts the overall height of the device, enhancing its versatility. The coordinated arrangement of the adjusting rod, first positioning seat, and fixed seat allows for positional changes in the fixed seat, moving the first positioning seat and adjusting rod, depending on the user's location. This, in turn, alters the device's horizontal position within a certain range. Furthermore, in conjunction with the support rods and support sleeves, it enables varying degrees of horizontal and vertical adjustment. The relative rotation between the fixed seat, first positioning seat, and adjusting rod can also alter the device's horizontal direction and pitch angle, further expanding its adjustability.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0024] Please see Figures 1 to 4 This utility model embodiment provides a face recognition device frame, which can be applied to installation walls of different heights, door frames of different tilt angles, and complex indoor and outdoor lighting environments. This embodiment improves the structure of the face recognition device frame to give it the advantages of multi-height, multi-angle, and multi-position adjustment. Specifically, taking face recognition for people of different heights as an example, as a preferred solution in this embodiment, the face recognition device frame is specifically a face recognition device frame with a flexibly adjustable installation angle, capable of multi-dimensional flexible adjustment of height, horizontal position, tilt angle, and horizontal rotation angle.

[0025] Please see Figures 1 to 4 This utility model provides a technical solution: a face recognition device frame with a flexibly adjustable installation angle. This face recognition device frame is mainly used on installation walls of different heights, door frames of different tilt angles, and complex indoor and outdoor lighting environments.

[0026] The device includes a support sleeve, a support rod slidably connected to the inner wall of the support sleeve, a positioning shaft fixedly connected to the end of the support rod, an adjusting rod rotatably connected to the bottom of the support sleeve via a rotating shaft, a first positioning seat connected to the end of the adjusting rod via a rotating shaft, a fixed seat rotatably connected to one side of the first positioning seat via a rotating shaft, a positioning disc fixedly connected to one side of the fixed seat, an adjusting disc sleeved on the outer surface of the positioning disc, and a support frame fixedly connected to the outer surface of the adjusting disc.

[0027] In this embodiment, a support sleeve serves as the basic support structure for the entire outer frame, providing a sliding track for the internal support rods. It is connected to the adjusting rod via a bottom pivot, enabling angle adjustment and ensuring the overall stability of the outer frame. This also provides the structural basis for height adjustment. The support rods slide against the inner wall of the support sleeve, allowing adjustment of the overall height of the outer frame by changing the extension length. The positioning shaft at the end connects to the first positioning seat, enabling flexible vertical adjustment of the equipment to adapt to different installation height requirements. The adjusting rod connects to the support sleeve and the first positioning seat via pivots at both ends, forming a linkage structure that assists in adjusting the horizontal position and angle of the outer frame, expanding its adjustment range and allowing the equipment to adapt to different installation positions and usage scenarios. The first positioning seat connects to the fixed seat via a pivot, enabling horizontal and pitch angle adjustments. The fixed seat is used to install the positioning plate and adjusting plate, providing multi-dimensional angle adjustment capabilities, allowing the equipment lens to accurately align with the target. The adjusting plate is fitted onto the outside of the positioning plate and can rotate relative to it to adjust the horizontal rotation angle. The pressure rod connects to the positioning plate via a thread and presses against the adjusting plate, locking the angle and achieving 360° horizontal rotation adjustment, while providing a reliable locking mechanism.

[0028] In the above embodiments, as a preferred option, a threaded sleeve is connected through the outer surface of the support rod, and a protective cylinder is fitted onto the outer surface of the threaded sleeve. A compression spring is fixedly connected to the inner bottom wall of the protective cylinder. The threaded sleeve passes through the support rod and is used to fix the protective cylinder. The compression spring, pressure block, and anti-slip pad inside the protective cylinder work together to lock the position of the support rod through friction, providing a locking function after height adjustment, preventing the support rod from sliding accidentally, and enhancing structural stability.

[0029] In the above embodiments, as a preferred solution, a pressure block is fixedly connected to the end of the compression spring, and an anti-slip pad is fixedly connected to the end of the pressure block. The outer surface of the anti-slip pad abuts against the outer surface of the support rod. The pressure block is pushed by the compression spring through elastic force, so that the anti-slip pad tightly abuts against the surface of the support rod, generating friction to prevent sliding. Quick locking and unlocking can be achieved without tools, and the operation is simple and the locking is reliable.

[0030] In the above embodiment, as a preferred solution, a second positioning seat is rotatably connected to the outer surface of the positioning shaft. A limit rod is threadedly connected to one end of the positioning shaft that passes through the second positioning seat. A bolt hole is opened on the top of the second positioning seat. The positioning shaft connects the support rod and the second positioning seat to realize the rotatable connection between the two. The limit rod prevents the second positioning seat from falling off the positioning shaft, ensuring the stability of the structural connection, while allowing the second positioning seat to be adjusted in angle.

[0031] In the above embodiments, as a preferred option, anti-slip washers are fixedly connected to both sides of the outer surface of the adjusting rod and the top of the fixed seat. The outer surfaces of multiple anti-slip washers are in contact with the inner sidewalls of the support sleeve and the first positioning seat, respectively. By setting the anti-slip washers on the surfaces of the adjusting rod and the fixed seat, the friction is increased to prevent the structure from loosening, improve the stability after adjustment, and ensure that the equipment maintains a fixed angle during long-term use, avoiding displacement due to vibration or external force.

[0032] In the above embodiments, as a preferred option, a pressure rod is threadedly connected to the outer surface of the positioning disk, and the outer surface of the pressure rod abuts against the outer wall of the adjusting disk.

[0033] In the above embodiments, as a preferred option, threaded posts are inserted into the four corners of the outer surface of the support frame, and a limit ring is threaded to one end of the outer surface of the threaded post. The threaded post is used to fix the position of the protective shell, and the limit ring is used to lock the support frame to prevent it from loosening.

[0034] In the above embodiments, as a preferred option, a protective shell is fixedly connected to the other end of the outer surface of the threaded column, and a pressure cap is slidably connected to the top of the protective shell. The protective shell covers the edge of the device to provide physical protection, and the pressure cap is adjustable to facilitate the installation and removal of the face recognition device.

[0035] In this invention, the working steps of the device are as follows:

[0036] First, locate the installation foundation and fix the second positioning seat to the target installation position, such as a wall or door frame, using bolts through the bolt holes on the top of the second positioning seat to ensure the foundation is stable. Connect the support sleeve and the adjusting rod by hingedly connecting the rotating shaft at the bottom of the support sleeve and the rotating shaft at one end of the adjusting rod to form a rotatable connection. The other end of the adjusting rod is connected to the first positioning seat through the rotating shaft to build a foundation linkage structure.

[0037] Adjust the height of the sliding support rod by moving it up and down. Adjust its extension length inside the support sleeve according to the different heights of the people until the center of the device lens is aligned with the target height.

[0038] The anti-slip washers on both sides of the automatic limit adjustment rod and the top of the fixed seat contact the support sleeve and the inner wall of the first positioning seat to provide damping and prevent excessive shaking, while also helping to fix the adjusted position.

[0039] The tilt angle adjustment rotating fixed base is used to swing up and down around the rotating shaft connected to the first positioning base to adjust the tilt angle of the equipment lens;

[0040] Horizontal rotation adjustment involves directly rotating the support frame, causing the adjustment disc to rotate around the positioning disc, thus adjusting the horizontal orientation of the lens.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
