Description

Technical Field

[0001] The utility model relates to the field of access control gates, and more specifically, to a fixing mechanism and a passage management device for face recognition equipment. Background Art

[0002] Intelligent access management systems integrate facial recognition devices with gate systems, using facial recognition technology to intelligently open and close gate channels. Facial recognition devices are typically located on the upper surface of the gate itself and can be fixed in various ways. For example, a dual-screen facial recognition attendance machine (published as CN219655614U) uses screws to secure the base of the facial recognition device directly to the gate itself. Alternatively, the facial recognition device is equipped with a threaded post, which is then secured to the gate using a lock nut.

[0003] While implementing the concept of this utility model, the inventors discovered that the threaded connection between the facial recognition device and the gate body made installation cumbersome and required specialized tools. Furthermore, securing the device to the gate body requires inserting nuts and other fasteners through the gate body's outer casing until the device is securely fastened. This process often presents difficulties due to the limited internal space of the gate body. Maintenance and replacement of the facial recognition device also presents difficulties in disassembly and assembly, which is time-consuming and labor-intensive. Utility Model Content

Detailed implementation manners

[0030] Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, it should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present invention. In the following detailed description, for the sake of explanation, many specific details are set forth to provide a comprehensive understanding of the embodiments of the present invention. However, obviously, one or more embodiments can also be implemented without these specific details. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concept of the present invention.

[0031] In the technical solution of the present utility model, the user information involved (including but not limited to user personal information, user face image information) and data (including but not limited to data for analysis, stored data, displayed data, etc.) are all information and data authorized by the user or fully authorized by all parties.

[0032] In scenarios where automated decision-making (such as access management) is carried out using face recognition devices, the institutions and devices provided by the embodiments of the present utility model all provide corresponding operation entrances for users to choose to agree or refuse to use face recognition in access management.

[0033] Figure 1 The structural diagram of the access management device according to the embodiment of the present utility model is schematically shown. It should be noted that Figure 1 What is shown is only an example to which the embodiments of the present utility model can be applied, to help those skilled in the art understand the technical content of the present utility model, and is not limited to Figure 1 the size, structure, and shape of the shown access management device.

[0034] As Figure 1 shown, the access management device includes a turnstile body 1, a baffle 3, and a face recognition device 4. A passage 2 for personnel to pass through the access turnstile body 1 is formed between two oppositely arranged turnstile bodies 1. When the target person approaches the entrance end of the passage 2, the camera on the face recognition device 4 can capture face image data, and the display screen 42 on the face recognition device 4 can display the captured face image. A processor is set locally or remotely on the face recognition device 4 to compare and identify the face image with the faces in the database. After the target person is successfully recognized, the baffle 3 movably arranged inside the turnstile body 1 moves to open, and the person enters the passage 2 and leaves from the exit end of the passage 2.

Figure 3 The rear view of the connection and fixing mechanism of the face recognition device according to the embodiment of the present utility model is schematically shown. Figure 4 The side view of the connection and fixing mechanism of the face recognition device according to the embodiment of the present utility model is schematically shown. Figure 5 The three-dimensional view of the column connection and fixing mechanism of the face recognition device according to the embodiment of the present utility model is schematically shown. Figure 6 The three-dimensional view of the fixing mechanism according to the embodiment of the present utility model is schematically shown.

[0036] In some embodiments, the fixing mechanism 5 is used to fix the face recognition device 4 to the turnstile body 1. The fixing mechanism 5 specifically includes a fixing base 51 and an external force member 52. The fixing base 51 includes a first fixing member 511 and a second fixing member 512 (such as a clamping plate) arranged oppositely. The first side of the first fixing member 511 is configured to be connected to the turnstile body 1; the external force member 52 is configured to apply an external force to the second fixing member 512 so that the second side of the first fixing member 511 abuts against the second fixing member 512 to form an accommodation space between the two fixing members; wherein, by adjusting the magnitude of the external force applied by the external force member 52 to the second fixing member 512, the upright column 41 of the face recognition device 4 is fixed or released within the accommodation space.

[0037] Referring to Figures 1 - 6 , the first side of the first fixing member 511 can be the side connected to the turnstile body 1, such as Figure 2 the left side of the fixing mechanism 5 shown. The first side of the first fixing member 511 can be indirectly connected to the turnstile body 1, such as Figure 2 connected to the turnstile body 1 through the support member 6 in

[0038] Exemplarily, the first side and the second side of the first fixing member 511 are different. For example, they can be opposite sides or intersecting sides. The shapes of the first fixing member 511 and the second fixing member 512 can be the same or different. For example, the first fixing member 511 is similar to or the same as half of a pipe clamp, and the second fixing member 512 is similar to or the same as the other half of the pipe clamp, then the shapes of the two fixing members are substantially the same; the materials of the first fixing member 511 and the second fixing member 512 can be the same or different. For example, they can both be metal materials, such as iron, or one of them can be a metal material while the other is a plastic; at least one of the first fixing member 511 and the second fixing member 512 can be a rigid member or a flexible member.

[0039] Exemplarily, the external force member 52 includes a mechanical structure that can apply an external force. An external force is applied to at least one position between the first fixing member 511 and the second fixing member 512. For example, there can be no mechanical connection between the first fixing member 511 and the second fixing member 512, and they are abutted together by the force applied by one or more external force members 52 around. Or, there can be a partial mechanical connection between the first fixing member 511 and the second fixing member 512, and the external force member 52 applies a force to the area without mechanical connection.

[0040] In some embodiments, the external force member 52 may include a spring. Referring to Figure 2 and Figure 4 the side view direction of [[ID=]], for example, the first fixing member 511, the second fixing member 512, and the spring are arranged in sequence from left to right. The left side of the spring abuts against the second fixing member 512, and the right side of the spring is fixed to another stopper (not shown in the figure). By adjusting the distance between the stopper and the second fixing member 512, the compression amount of the spring is further adjusted to achieve the purpose of adjusting the pressure.

[0041] In some embodiments, the external force member 52 may include an electromagnet. For example, the second fixing member 512 is made of ferromagnetic material, and the electromagnet can be installed on the first fixing member 511. By changing the magnitude of the current, the intensity of the magnetic field can be controlled, and thus the attraction force applied to the second fixing member 512 can be controlled.

[0042] Exemplarily, when both the first fixing member 511 and the second fixing member 512 are rigid members, the accommodating space may conform to the shape of the column 41, that is, at least one of the first fixing member 511 and the second fixing member 512 has a recess that conforms to the contact area of the column 41. When at least one of the first fixing member 511 and the second fixing member 512 is a flexible member, pressure is applied to the second fixing member 512, and the flexible member deforms to adapt to the shape of the column 41 between the two fixing members, so that the accommodating space conforms to the shape of the column 41.

[0043] According to an embodiment of the present invention, the face recognition device 4 is installed between the first fixing member 511 and the second fixing member 512 of the fixed seat 51, rather than being directly connected to the turnstile body 1 by screws or threads. When disassembling, assembling or maintaining, it is only necessary to adjust the accommodating space between the first fixing member 511 and the second fixing member 512, thereby overcoming the problem of difficult fastening due to the limited internal space of the turnstile body 1 in the related art. In addition, by adjusting the magnitude of the external force applied by the external force member 52 to the second fixing member 512, the column 41 of the face recognition device 4 is fixed or released in the accommodating space, replacing the fixing method using fasteners such as screws and bolts, realizing the quick fixing of the face recognition device 4, without the need to use special tools, being simple to install and having reliable fixation.

[0044] Figure 7 A perspective view of a bracket according to an embodiment of the present invention is schematically shown. Figure 8 A perspective view of a quick clamp according to an embodiment of the present invention is schematically shown. In some embodiments, the external force member 52 may further include a quick clamp, which will be further described in detail below.

[0045] Exemplarily, the fixing mechanism 5 further includes a bracket 7. The bracket 7 is connected to the first fixing member 511, for example, at the bottom of the first fixing member 511; the external force member 52 includes at least one quick clamp. At least one quick clamp is mounted on the bracket 7, wherein each quick clamp includes a pressing head 5242 configured to apply pressure to the second fixing member 512 to bring the second side of the first fixing member 511 into abutment with the second fixing member 512.

[0046] In some embodiments, each quick clamp includes a base 521, a follower rod 522, a pressing rod 523, and a pressing assembly 524. The base 521 is connected to the bracket 7; the follower rod 522 is swingably disposed on the base 521, and the connecting end of the follower rod 522 is hinged to the base 521, as Figure 2 extending in the vertical direction; the pressing rod 523 is swingably disposed on the base 521, and the connecting end of the pressing rod 523 is hinged to the base 521, as Figure 2 extending in the horizontal direction, and the pressing rod 523 causes the follower rod 522 to swing; the pressing assembly 524 includes a connecting rod 5241 and a pressing head 5242, one end of the connecting rod 5241 is connected to the pressing head 5242, and the other end of the connecting rod 5241 is connected to the free end of the follower rod 522; wherein, as the pressing rod 523 swings, the pressing head 5242 is configured to apply pressure or release pressure to the second fixing member 512.

[0047] Referring to Figures 1 - 8 , the bracket 7 includes a reinforcing rib 73, a vertical portion 72, and a horizontal portion 71. The bracket 7 is entirely located below the fixing base 51, the horizontal portion 71 is connected to the bottom of the fixing base 51, and the vertical portion 72 is connected to the base 521 of the quick clamp. The reinforcing rib 73 is disposed between the vertical portion 72 and the horizontal portion 71, serving to enhance the structural strength and stiffness. Specifically, the vertical portion 72 and the horizontal portion 71 can be obtained by bending a metal profile by sheet metal working, and then the reinforcing rib 73 is welded between the vertical portion 72 and the horizontal portion 71.

[0048] Exemplarily, the follower rod 522 is swingably disposed on the base 521 in the up-and-down direction, and the connecting end of the follower rod 522 is hinged to the base 521; the base 521 includes two symmetric members arranged symmetrically left and right, and each base 521 is provided with a fixing hole fixedly connected to the outside; the follower rod 522 is bent into a structure symmetrically arranged left and right, and an installation groove extending forward and backward is formed in the middle. The pressing rod 523 is swingably disposed on the base 521 in the up-and-down direction, and the connecting end of the pressing rod 523 is hinged to the base 521. The pressing rod 523 causes the follower rod 522 to swing in a direction approaching or away from the bracket 7; the connecting end of the pressing rod 523 branches into a symmetric structure left and right, the end is connected to the base 521, and an installation groove is formed in the middle. The follower rod 522 extends from the base 521 through the installation groove to the free end. The pressing assembly 524 includes a connecting rod 5241 and a pressing head 5242. The upper end of the connecting rod 5241 is connected to the free end of the follower rod 522, and the pressing head 5242 is installed at the lower end of the connecting rod 5241. The connecting rod 5241 is movably installed in the installation groove at the free end of the follower rod 522 in the front-back direction; the connecting rod 5241 is fixed in the installation groove by a nut.

[0049] As Figure 8 shown, the pressing head 5242 may have a tapered shape, and the diameter is larger the closer it is to the connecting rod 5241. The end of the pressing head 5242 in contact with the second fixing member 512 is a circle with the smallest diameter, and the contact surface may be a circular plane to better apply pressure. Since the connecting rod 5241 can be moved and adjusted in the installation groove at the free end of the follower rod 522, it can play a fixing role for columns 41 of different sizes and can also play a role in adjusting the pressure.

[0050] According to an embodiment of the present invention, by adjusting the magnitude of the external force applied by the pressing head 5242 of the quick clamp to the second fixing member 512, the column 41 of the face recognition device 4 is fixed or released in the accommodation space, realizing the quick fixing of the face recognition device 4, with simple installation and reliable fixing.

[0051] In some embodiments, each quick clamp applies pressure to the second fixing member 512 through the pressing head 5242 to a specific value, so that the column 41 of the face recognition device 4 is clamped in the accommodation space to achieve fixation.

[0052] Referring to Figures 1 - 8 , the specific value can be determined in advance according to the fixing state of the column 41 through a sensor and a control system, such as 5 Newtons (for example only). And when implementing the fixation, it can be measured by a measuring instrument whether the pressure reaches the specific value. In some embodiments, the magnitude of the pressure can be judged according to the position of the pressing rod 523. When the pressing rod 523 is in a specific position, it can be considered that the pressure applied to the second fixing member 512 reaches the specific value, such as Figure 2 the current position shown.

[0053] According to an embodiment of the present utility model, fixation is achieved by clamping the upright post 41, which is simpler than using fasteners such as screws and can also save the cost of fasteners. The pressure is precisely controlled to a specific value, making the fixation of the upright post 41 stable and reliable.

[0054] In some embodiments, the second fixing member 512 includes a first end and a second end. The first end is rotatably connected to the second side of the first fixing member 511; the second end is pressed by the pressing head 5242 of at least one quick clamp and abuts against the second side of the first fixing member 511.

[0055] In some embodiments, the second fixing member 512 further includes a first bending portion 5121 located between the first end and the second end, and the first bending portion 5121 constitutes a side wall of one side of the accommodating space.

[0056] In some embodiments, the first fixing member 511 includes a first fixing portion 5111 and a second fixing portion 5112. The first fixing portion 5111 is located on the first side and is configured to be connected to the turnstile body 1; the second fixing portion 5112 is located on the second side and is connected to the first fixing portion 5111; wherein, a cavity is formed between the second fixing portion 5112 and the first fixing portion 5111, and the second fixing portion 5112 includes a second bending portion 51121 bent toward the cavity, and the second bending portion 51121 constitutes a side wall of the other side of the accommodating space, and the first bending portion 5121 and the second bending portion 51121 are disposed opposite to each other to form the accommodating space.

[0057] Exemplarily, the upright post 41 may be cylindrical. Referring to Figure 6 ..., both the first bending portion 5121 and the second bending portion 51121 are arc-shaped bends, and both have semi-cylindrical arc surfaces (as the side walls of the accommodating space). When the second fixing member 512 is pressed by the quick clamp, the accommodating space is an approximate cylindrical space. This space is used to install and fix the upright post 41 of the face recognition device 4.

[0058] In some embodiments, the first fixing portion 5111 includes a fixing plate 51111 and a first folding ear mechanism 51112. The fixing plate 51111 is connected to the turnstile body 1; the first folding ear structure is connected to the fixing plate 51111 and the second bending portion 51121, and the first folding ear structure and the fixing plate 51111 cooperate to form a cavity.

[0059] Exemplarily, the fixing plate 51111 can be a rectangular thin plate made of metal, with threaded holes opened at four corners respectively for four bolts to pass through the corresponding threaded holes and connect to the turnstile body 1 or the support frame 6. The first ear structure can be integral with or separated from the fixing plate 51111. For example, the fixing plate 51111 and the first ear structure are integrally formed by bending a metal profile through sheet metal working. Or, in the case of separation, two symmetric ear pieces are welded to both sides of the fixing plate 51111. The middle part of the first ear structure has an arc recessed towards the cavity direction, and this arc matches the second bending part 51121, and the two can be connected by welding. The cavity formed by the cooperation of the first ear structure and the fixing plate 51111 is an open space.

[0060] In some embodiments, the first end includes a second ear structure 5122, and the second ear structure 5122 is configured to be installed opposite to the first ear structure; the first fixing member 511 further includes a rotating shaft 5113. The rotating shaft 5113 is installed in the cavity, and the rotating shaft 5113 passes through the overlapping ear parts between the first ear structure and the second ear structure 5122, so that the first end is rotatably connected to the second side of the first fixing member 511.

[0061] It should be noted that using a rotating shaft to achieve the rotational connection is only one embodiment of the present invention. For example, it can also be distributed and hinged or ball-jointed through the overlapping ear parts on both sides of the first ear structure and the second ear structure.

[0062] In some embodiments, the second fixing portion 5112 further includes an abutting portion. The abutting portion and the fixing plate 51111 are arranged oppositely on both sides of the first ear structure, and are arranged oppositely to the rotating shaft 5113 on both sides of the second bending part 51121; wherein, the abutting portion is connected to the first ear structure and is configured to abut against the second end.

[0063] Refer to Figure 6 , the abutting portion can be a plate-shaped member with a flat top. This plate-shaped member is installed at the opening of the first ear structure, and this opening corresponds to the second end of the second fixing member 512. The second fixing member 512 is integrally in a shape with a middle bend and two flat ends. The difference between the two ends is that the first end is provided with a connected flat plate portion and a second ear structure 5122, and the function is to rotatably connect to the first fixing member 511, and the second end is in a flat plate shape, which is convenient for abutting against the abutting portion. In some embodiments, screw holes can also be opened at the second end of the second fixing member 512. If the external force member 52 is damaged or not replaced in time, screws can be used to connect the first fixing member 511 and the second fixing member 512 to clamp the upright column 41.

[0064] In some embodiments, at least a portion of the sidewalls of the accommodation space are affixed with rubber pads, which can prevent damage to the pillars 41 or the sidewalls of the accommodation space and reduce the inner diameter of the accommodation space to better clamp the pillars 41.

[0065] Reference Figures 1 - 8 , the process of quickly fixing the face recognition device 4 is further described below.

[0066] First, after the support frame is connected to the gate body 1, the fixing mechanism 5 is installed on the support frame.

[0067] Next, the pressure rod 523 of the quick caliper is moved, such as by moving the handle of the pressure rod 523, so that the pressure head 5242 is away from the second fixing member 512, such as a clamping plate. The second fixing member 512 is rotated to a maximum angle.

[0068] Next, insert the column 41 of the face recognition device 4 into the cylindrical arc surface of the second bending portion 51121, rotate the second fixing member 512 until its second end is in contact with the abutting portion of the first fixing member 511, and the first bending portion 5121 and the second bending portion 51121 wrap the column 41 of the face device.

[0069] Finally, the handle of the quick clamp pressure rod 523 is toggled to allow the pressure head 5242 to press the second end of the second fixing member 512. At this time, the column 41 of the face recognition device 4 is also tightened.

[0070] When the facial recognition device 4 is subsequently maintained or replaced, or the column 41 is rotated, the handle of the quick clamp is pulled back, the pressure head 5242 thereof is lifted, the second fixing member 512 becomes movable, and the column 41 of the facial recognition device 4 is loosened.

[0071] The above describes the embodiments of the present invention.
