Description

Technical Field

[0001] This application relates to the field of time and attendance machine technology, and more specifically to a time and attendance machine bracket assembly and a time and attendance machine. Background Technology

[0002] A time and attendance machine (TOD) is a device used to record employee attendance. It is widely used in businesses, schools, factories, and other locations to manage the attendance of employees and students. The core principle of TODs is primarily based on biometric and electronic sensing technologies. Common types of TODs include fingerprint TODs, facial recognition TODs, and card-swipe TODs. Among these, facial recognition TODs use a camera to capture facial images and extract and compare facial features through facial recognition algorithms to identify individuals and record attendance. They offer advantages such as being contactless and fast, making them suitable for locations with high foot traffic. In practical use, TODs typically require a stand for stable installation in a suitable location for convenient attendance tracking. However, traditional TOD stands are usually designed with a fixed angle, making them unadjustable based on user height and usage habits. This results in inconsistent camera field of view for users of different heights, causing inconvenience.

[0003] To address the aforementioned issues, Chinese utility model patent CN218153148U discloses a height-adjustable face recognition attendance machine. This machine includes an adjustment frame, inside which is the attendance machine body. An adjustment mechanism is located at the bottom of the attendance machine body. The adjustment mechanism includes an anti-slip sleeve, a pull rod, a fixing block, and two fixing rods. The anti-slip sleeve is fixedly fitted onto the surface of the pull rod. The pull rod is fixedly connected between the two fixing rods on opposite sides. The top of each fixing rod passes through the fixing block and extends to its top. The top of each fixing rod is fixedly connected to the bottom of the attendance machine body. Sliding grooves are provided on both sides of the inner wall of the adjustment frame. In this technical solution, by setting up the anti-slip sleeve, pull rod, fixing block, and fixing rods, pulling the anti-slip sleeve moves the pull rod and fixing rods, thereby changing the height of the attendance machine body. Simultaneously, the engagement of the limiting block and teeth provides limiting, meeting the usage needs of users of different heights. However, when users of different heights use the time attendance machine, even if the height is suitable, the fixed camera angle may still prevent the camera from being at the optimal viewing angle, affecting the recognition effect and the attendance experience. Users still need to constantly adjust their position and posture to ensure that their face is within the optimal recognition range of the camera, which increases the difficulty and time cost of attendance. On the other hand, in order to ensure that the device can adjust its height normally, the height-adjustable time attendance machine needs to occupy a lot of space, which is quite restrictive. Summary of the Invention

[0004] The technical problem to be solved by this application is to provide a bracket assembly for a time attendance machine and the time attendance machine itself. The bracket assembly, through the design of a support base and an adjustment mechanism, realizes the angle adjustment function of the time attendance machine, optimizes space utilization, improves structural stability, and simplifies the operation process.

[0005] This application provides a support assembly for a time attendance machine, including a support base and an adjustment mechanism. The adjustment mechanism is used to connect to the time attendance machine body and is movably mounted on the support base. The support base is provided with an arc-shaped guide rail adapted to the adjustment mechanism. When the adjustment mechanism is subjected to force, it can drive the time attendance machine body to move along the arc-shaped guide rail to adjust the angle of the time attendance machine body.

[0006] In this technical solution, the support base is the basic structure of the bracket assembly, providing stable support for the installation and fixation of the attendance machine body. The adjustment mechanism is connected to the attendance machine body and is movably mounted on the support base to realize the angle adjustment function of the attendance machine. By adding an arc-shaped guide rail on the support base, a predetermined movement path is provided, allowing the adjustment mechanism to move along the arc-shaped trajectory. By applying external force (such as manual pushing or pulling or mechanical drive), the adjustment mechanism can drive the attendance machine body to move along the arc-shaped guide rail, realizing the angle adjustment of the attendance machine. The adjustment mechanism can adjust the angle of the attendance machine according to the user's height and usage habits, so that the camera is at the optimal viewing angle, improving the accuracy of recognition and the convenience of clocking in. Users can quickly adjust the angle of the attendance machine through simple manual operation or mechanical drive, without complicated tools or steps, improving the ease of use of the equipment. The design of the arc-shaped guide rail allows the adjustment action of the attendance machine to be carried out on a preset arc-shaped path. Compared with the traditional height adjustment design, this design can make more compact use of space.

[0007] As an improvement, the arc-shaped guide rail is provided with multiple locking positions, and the adjustment mechanism is provided with latches adapted to the locking positions. Force applied to the adjustment mechanism can connect or disengage the latches from the locking positions. In this technical solution, the locking positions are typically designed as a series of grooves, holes, or protrusions distributed on the arc-shaped guide rail. These locking positions are adapted to the latches on the adjustment mechanism, ensuring that the adjustment mechanism can be fixed in multiple preset positions. The latches are designed to connect or disengage from the locking positions. By applying external force (such as manual pushing or pulling), the user can control the connection or disengagement of the latches from the locking positions, thereby achieving angle adjustment of the attendance machine. This ensures that the user can quickly and conveniently adjust the angle of the attendance machine and fix it in place after adjustment to the appropriate position.

[0008] As an improvement, the multiple locking positions are arranged in a wave-like structure, and the latch is an arc-shaped protrusion structure. The locking positions and the latch are elastically engaged. In this technical solution, multiple consecutive locking positions are designed as a wave-like structure, which consists of multiple consecutive concave and convex portions. The concave portions are used to accommodate the latch and serve as the fixed position of the latch, while the convex portions are used to restrict the movement of the latch, ensuring that the latch can only be fixed in a preset position. The locking positions and the latch are designed to elastically engage. The adjustment mechanism and support base in this application can be made of elastic materials (such as plastic). The connection and disengagement between the latch and the locking position depend entirely on the elastic deformation of the material. When the user applies external force, the latch can elastically deform and thus disengage from the locking position. When the external force disappears, the latch returns to its original shape and reconnects to the locking position. There is no need to add an additional unlocking mechanism, which simplifies the structure, reduces costs, and maintains good connection and disengagement performance. Users can quickly adjust the angle of the attendance machine through simple manual push and pull operations.

[0009] As an improvement, the adjustment mechanism includes a connector. One end of the connector is used to connect to the attendance machine body, and the other end of the connector is provided with a connecting seat. The connecting seat is movably connected to the arc-shaped guide rail, and the latch is disposed on the connecting seat. In this technical solution, the connector is used to connect the attendance machine body and the support base, ensuring that the attendance machine body can adjust its angle as the adjustment mechanism moves. The other end of the connector is designed with a connecting seat, which allows the attendance machine body to be stably fixed on the connector and connected to the support base through the connecting seat. The latch is integrally formed on the connecting seat, reducing the number of parts, lowering manufacturing costs and assembly difficulty, and making the bracket assembly lighter and more compact, suitable for installation in places with limited space.

[0010] As an improvement, the adjustment mechanism further includes a mounting plate located within the support base and connected to the connecting seat. The mounting plate cooperates with the connecting seat to confine the connecting member on the support base. In this technical solution, the mounting plate is used to confine the connecting member on the support base. The mounting plate and the connecting seat can be connected by threads to ensure the stability and fixation of the connecting member on the support base, preventing displacement or loosening due to external forces or vibrations, thus improving the reliability and service life of the equipment. On the other hand, the design of the mounting plate and connecting seat simplifies the installation structure and steps of the adjustment mechanism, reduces the number of parts, and lowers manufacturing costs and assembly difficulty.

[0011] As an improvement, two arc-shaped guide rails are provided, and two corresponding locking buckles are also provided on the arc-shaped guide rails; the two arc-shaped guide rails and the two locking buckles are symmetrically distributed. In this technical solution, the two arc-shaped guide rails provide two predetermined movement paths. The two arc-shaped guide rails are symmetrically distributed on the support base, enabling the adjustment mechanism to maintain balance and stability during movement. The symmetrically distributed arc-shaped guide rails can provide more uniform support force, reducing swaying or offset caused by uneven force on one side. The two locking buckles are symmetrically distributed and cooperate with the locking positions on the two arc-shaped guide rails respectively, providing a more stable fixing effect and ensuring the stability of the attendance machine in a fixed position.

[0012] As an improvement, the support base includes a housing and a base plate, which are connected by fasteners. The housing has an arc-shaped end, and the arc-shaped guide rail is mounted on the arc-shaped end. In this technical solution, the support base consists of a housing and a base plate, which are connected by fasteners (such as screws and bolts) to form an integral structure. The split design makes the assembly and maintenance of the support base and adjustment mechanism more convenient. The arc-shaped end design allows for a tighter fit between the arc-shaped guide rail and the housing, ensuring the stability and fixation of the arc-shaped guide rail, and making the design of the arc-shaped guide rail more reasonable.

[0013] As an improvement, a counterweight is installed inside the support base. In this technical solution, the counterweight is used to increase the weight of the support base, improve the stability of the entire bracket assembly, and reduce swaying or displacement caused by external forces or vibrations. The installation position and weight of the counterweight can be adjusted according to actual needs to achieve the best stability effect.

[0014] This application may also provide a time attendance machine, including a support assembly of any of the aforementioned time attendance machines, and a time attendance machine body, which is connected to the adjustment mechanism. In this technical solution, the time attendance machine body, as the main part of the time attendance machine, is responsible for performing attendance operations. The time attendance machine body typically includes components such as a camera, sensor, and display screen, used to identify and record attendance information. The time attendance machine body is connected to the adjustment mechanism via a connector to ensure that it can move and be fixed with the adjustment mechanism. The adjustment mechanism is connected to the time attendance machine body and is movably mounted on a support base to realize the angle adjustment of the time attendance machine, improving the flexibility and adaptability of the equipment.

[0015] As an improvement, the attendance machine body is provided with a mounting slot adapted to the adjustment mechanism. The adjustment mechanism is connected to the mounting slot, and the adjustment mechanism and the mounting slot are fixed by fasteners. In this technical solution, the mounting slot provides a fixed interface, enabling the attendance machine body to connect with the adjustment mechanism. The shape and size of the mounting slot match the connecting parts of the adjustment mechanism, ensuring a tight fit between the two. The connecting parts of the adjustment mechanism cooperate with the mounting slot of the attendance machine body and are fixed by fasteners (such as screws, bolts, etc.), improving the stability and reliability of the connection.

[0026] Example 1 like Figures 1 to 4As shown, this application discloses a support assembly for a time attendance machine, including a support base 1 and an adjustment mechanism 2. The adjustment mechanism 2 is used to connect the time attendance machine body 3 and is movably mounted on the support base 1. The support base 1 is provided with an arc-shaped guide rail 11 adapted to the adjustment mechanism 2. When the adjustment mechanism 2 is subjected to force, it can drive the time attendance machine body 3 to move along the arc-shaped guide rail 11 to adjust the angle of the time attendance machine body 3. The support base 1 is the basic structure of the support assembly, providing stable support for the installation and fixation of the time attendance machine body 3. The adjustment mechanism 2 is connected to the time attendance machine body 3 and is movably mounted on the support base 1 to realize the angle adjustment function of the time attendance machine. By adding an arc-shaped guide rail 11 to the support base 1, a predetermined movement path is provided, allowing the adjustment mechanism to move along the arc-shaped guide rail 11. 2. The time attendance machine body 3 can move along an arc-shaped trajectory. By applying external force (such as manual pushing or pulling or mechanical drive), the adjustment mechanism 2 can drive the time attendance machine body 3 to move along the arc-shaped guide rail 11 to realize the angle adjustment of the time attendance machine. The adjustment mechanism 2 can adjust the angle of the time attendance machine according to the user's height and usage habits, so that the camera is at the best viewing angle, improving the accuracy of recognition and the convenience of clocking in. Users can quickly adjust the angle of the time attendance machine through simple manual operation or mechanical drive without complicated tools or steps, which improves the ease of use of the equipment. The design of the arc-shaped guide rail 11 makes the adjustment action of the time attendance machine perform on a preset arc-shaped path. Compared with the traditional height adjustment design, this design can make more compact use of space.

[0027] More specifically, such as Figure 1 and Figure 3 As shown, the arc-shaped guide rail 11 is provided with multiple locking positions 12. The adjustment mechanism 2 is provided with a latch 21 that is adapted to the locking position 12. When the adjustment mechanism 2 is subjected to force, the latch 21 can be connected or disengaged from the locking position 12. The locking position 12 is usually designed as a series of grooves, holes or protrusions distributed on the arc-shaped guide rail 11. These locking positions 12 are adapted to the latch 21 on the adjustment mechanism 2 to ensure that the adjustment mechanism 2 can be fixed in multiple preset positions. The latch 21 is designed to be able to connect or disengage from the locking position 12. By applying external force (such as manual push and pull), the user can control the connection or disengagement of the latch 21 from the locking position 12, thereby realizing the angle adjustment of the attendance machine. This ensures that the user can quickly and conveniently adjust the angle of the attendance machine and fix it after adjusting it to a suitable position.

[0028] More specifically, such as Figures 1 to 3As shown, multiple locking positions 12 have a wave-like structure, and the latch 21 has an arc-shaped protrusion structure. The locking positions 12 and the latch 21 are elastically engaged. The multiple consecutive locking positions 12 are designed as a wave-like structure, which consists of multiple consecutive concave and convex parts. The concave parts are used to accommodate the latch 21 and serve as the fixed position of the latch 21, while the convex parts are used to restrict the movement of the latch 21, ensuring that the latch 21 can only be fixed in the preset position. The locking positions 12 and the latch 21 are designed to be elastically engaged. The adjustment mechanism 2 and the support base 1 in this application can be made of elastic materials (such as plastic). The connection and disengagement between the latch 21 and the locking position 12 depend entirely on the elastic deformation of the material. When the user applies external force, the latch 21 can elastically deform and thus disengage from the locking position 12. When the external force disappears, the latch 21 returns to its original shape and reconnects to the locking position 12. There is no need to add an additional unlocking mechanism, which simplifies the structure, reduces costs, and maintains good connection and disengagement performance. Users can quickly adjust the angle of the attendance machine through simple manual push and pull operations.

[0029] More specifically, such as Figure 2 and Figure 3 As shown, the adjustment mechanism 2 includes a connector 22. One end of the connector 22 is used to connect to the attendance machine body 3, and the other end of the connector 22 is provided with a connecting seat 23. The connecting seat 23 is movably connected to the arc-shaped guide rail 11. The latch 21 is set on the connecting seat 23. The connector 22 is used to connect the attendance machine body 3 and the support base 1, ensuring that the attendance machine body 3 can adjust its angle as the adjustment mechanism 2 moves. The other end of the connector 22 is designed with a connecting seat 23, so that the attendance machine body 3 can be stably fixed on the connector 22 and connected to the support base 1 through the connecting seat 23. The latch 21 is integrally formed on the connecting seat 23, which reduces the number of parts, reduces manufacturing costs and assembly difficulty, and makes the bracket assembly lighter and more compact, suitable for installation in places with limited space.

[0030] More specifically, such as Figure 2 and Figure 3 As shown, the adjustment mechanism 2 also includes a mounting plate 24, which is located inside the support base 1 and connected to the connecting base 23. The mounting plate 24 and the connecting base 23 cooperate to limit the connecting member 22 on the support base 1. The mounting plate 24 is used to limit the connecting member 22 on the support base 1. The mounting plate 24 and the connecting base 23 can be connected by threads to ensure the stability and fixation of the connecting member 22 on the support base 1. It will not shift or loosen due to external force or vibration, which improves the reliability and service life of the equipment. On the other hand, the design of the mounting plate 24 and the connecting base 23 simplifies the installation structure and installation steps of the adjustment mechanism 2, reduces the number of parts, and reduces manufacturing costs and assembly difficulty.

[0031] More specifically, such as Figures 1 to 3As shown, there are two arc-shaped guide rails 11, and two corresponding latches 21. The two arc-shaped guide rails 11 are symmetrically distributed, and the two latches 21 are also symmetrically distributed. The two arc-shaped guide rails 11 provide two predetermined movement paths. The two arc-shaped guide rails 11 are symmetrically distributed on the support base 1, which enables the adjustment mechanism 2 to maintain balance and stability during movement. The symmetrically distributed arc-shaped guide rails 11 can provide more uniform support force, reducing swaying or offset caused by uneven force on one side. The two latches 21 are symmetrically distributed and cooperate with the locking positions 12 on the two arc-shaped guide rails 11 respectively, providing a more stable fixing effect and ensuring the stability of the attendance machine in a fixed position.

[0032] More specifically, such as Figure 2 and Figure 3 As shown, the support base 1 includes a housing 13 and a base plate 14, which are connected by fasteners. The housing 13 is provided with an arc-shaped end 131, and an arc-shaped guide rail 11 is provided on the arc-shaped end 131. The support base 1 is composed of the housing 13 and the base plate 14, which are connected by fasteners (such as screws, bolts, etc.) to form an integral structure. The split design makes the assembly and maintenance of the support base 1 and the adjustment mechanism 2 more convenient. The design of the arc-shaped end 131 makes the arc-shaped guide rail 11 fit more tightly with the housing 13, ensuring the stability and fixation of the arc-shaped guide rail 11, and making the design of the arc-shaped guide rail 11 more reasonable.

[0033] More specifically, such as Figure 2 and Figure 3 As shown, a counterweight 4 is installed inside the support base 1. The counterweight 4 is used to increase the weight of the support base 1, improve the stability of the entire bracket assembly, and reduce swaying or displacement caused by external forces or vibrations. The installation position and weight of the counterweight 4 can be adjusted according to actual needs to achieve the best stability effect.

[0034] Example 2 like Figure 4 and Figure 5 As shown, this embodiment provides an attendance machine based on embodiment 1, including a support assembly for the attendance machine provided in embodiment 1, and an attendance machine body 3. The attendance machine body 3 is connected to the adjustment mechanism 2. The attendance machine body 3 is the main part of the attendance machine and is responsible for performing attendance operations. The attendance machine body 3 typically includes components such as a camera, sensor, and display screen for identifying and recording attendance information. The attendance machine body 3 is connected to the adjustment mechanism 2 through a connector 22 to ensure that it can move and be fixed with the adjustment mechanism 2. The adjustment mechanism 2 is connected to the attendance machine body 3 and is movably mounted on the support base 1 to realize the angle adjustment of the attendance machine, thereby improving the flexibility and adaptability of the equipment.

[0035] More specifically, such as Figure 4 and Figure 5 As shown, the attendance machine body 3 is provided with a mounting groove 31 that is adapted to the adjustment mechanism 2. The adjustment mechanism 2 is connected to the mounting groove 31 and the adjustment mechanism 2 is fixed to the mounting groove 31 by fasteners. The mounting groove 31 provides a fixed interface so that the attendance machine body 3 can be connected to the adjustment mechanism 2. The shape and size of the mounting groove 31 match the connector 22 of the adjustment mechanism 2 to ensure that the two can fit tightly. The connector 22 of the adjustment mechanism 2 cooperates with the mounting groove 31 of the attendance machine body 3 and is fixed by fasteners (such as screws, bolts, etc.), which improves the stability and reliability of the connection.

[0036] This application is not limited to the above-described preferred embodiments. Anyone can derive other products in various forms under the guidance of this application. However, regardless of any changes made to their shape or structure, any technical solution that is the same as or similar to that of this application falls within the protection scope of this application.
