Description

Technical Field

[0001] This utility model relates to the field of access control technology, and in particular to an access control controller with switchable form. Background Technology

[0002] Access control controllers, as a core component of modern building security systems, are primarily used to manage the communication and control of access control devices. They are typically connected to the building monitoring host to achieve centralized management of access control switches, authorization verification, and entry / exit records. Currently, access control controllers are generally installed using a wall-mounted design, which involves fixing them to the wall with metal brackets and then attaching the controller body to the brackets to complete the assembly. While this mounting method meets basic installation requirements, it has the following significant drawbacks in practical applications:

[0003] The existing wall-mounted design limits access control controllers to vertical walls, making them unsuitable for other usage scenarios. For example, in temporary offices, small shops, or situations requiring frequent relocation, users may need to place the controller on a desktop or in a cabinet. However, the existing structure lacks corresponding support or fixing design, resulting in insufficient installation flexibility and limiting the product's applicability.

[0004] Access control systems typically require continuous operation for extended periods, generating heat from their internal electronic components (such as CPUs and power modules). However, existing products often feature enclosed or semi-enclosed casings, and when wall-mounted, the back is flush against the wall, leading to heat buildup and difficulty in dissipating. Prolonged operation at high temperatures can cause performance degradation, accelerated component aging, and even malfunctions, especially in high-temperature environments. Although some products have ventilation holes in their casings, wall-mounting still hinders airflow, limiting heat dissipation. Utility Model Content

[0041] See Figures 1-8A switchable access control module includes a display module 10 and a control module 20. The control module 20 is disposed behind the display module 10 and rotatably disposed relative to the display module 10. The control module 20 includes a rear housing 210 and a front cover 220 connected to each other. A control main board 230 is disposed between the rear housing 210 and the front cover 220. The rear housing 210 has first ventilation openings 211 evenly distributed, and the front cover 220 has second ventilation openings 221 evenly distributed. A ventilation space 200 is disposed between the front cover 220 and the display module 10, and the ventilation space 200 is interconnected with the second ventilation openings 221. The control module 20 is provided with a locking module 30 for cooperating with the display module 10 to constrain the rotation of the control module 20 relative to the display module 10. In this embodiment, the control module is located behind the display module and is rotatably configured relative to the display module. This rotatability allows the control module to be rotated to a support position, providing support on a desktop or similar surface using the control module as a fulcrum. Simultaneously, a ventilation space is provided between the front cover and the display module, allowing for faster air exchange between the outside air and the space between the front cover and the rear housing, increasing the airflow area and thus improving heat dissipation efficiency.

[0042] External air can enter the rear housing 210 through the first vent 221 to provide heat dissipation for the control motherboard 230. Furthermore, external air can enter the rear housing 210 through the ventilation space 220 and the second vent 221 to provide heat dissipation for the control motherboard 230.

[0043] See Figure 4 The display module 10 has two connecting seats 100 spaced apart on the left and right sides. Each connecting seat 100 is connected to a rotating shaft 40, which is rotatably connected to the rear housing 210. Multiple locking grooves 101 are arranged circumferentially along the axis of the rotating shaft 40 on each connecting seat 100. Two locking modules 30 are provided, respectively located on the left and right sides of the rear housing 210. Each locking module 30 is movable relative to the rear housing 210 and can be movably inserted into any of the locking grooves 101. In this embodiment, the locking module 30 can be moved to lock or unlock. When locked, the control module 20 cannot rotate relative to the display module 10. When unlocked, the control module 20 can rotate relative to the display module 10 to adjust its angle, allowing switching between wall-mounted and desktop-supported states. Figure 1 The image shows the wall-mounted installation configuration. Figure 3 The image shows the device when placed on a desktop.

[0044] See Figure 4 and Figure 6The locking module 30 includes a movable locking rod 510 that can move relative to the rear housing 210 from a first position to a second position. A locking protrusion 511 is provided at one end of the movable locking rod 510 near the locking groove 101. When the movable locking rod 510 is in the first position, the locking protrusion 511 can be movably inserted into any one of the locking grooves 101. The rear housing 210 is provided with a spring 550, which applies force to the movable locking rod 510 to keep the locking protrusion 511 inserted into the locking groove 101. During unlocking, the movable locking rod 510 needs to be manually moved from the first position to the second position. During this process, the locking protrusion 511 gradually disengages from the locking groove 101, and the spring 550 is compressed and stores force until the locking protrusion 511 is completely disengaged from the locking groove 101, thus completing the unlocking process. After unlocking, the control module 20 can rotate relative to the display module 10 about the pivot 40.

[0045] See Figure 6 The rear housing 210 has guide grooves 212 on its left and right sides, and the movable locking rod 510 is movably mounted on the outer walls of the left and right sides of the rear housing 210. Guide seats 540 are provided on the inner walls of the left and right sides of the rear housing 210. The movable locking rod 510 is connected to at least two guide posts 520, which pass through the guide grooves 212 and connect to the guide seats 540. A spring 550 is disposed within the guide grooves 212, with one end connected to the inner wall of the guide groove 212 and the other end connected to the guide posts 520. The cooperation between the guide seats 540 and the movable locking rod 510 restricts their movement relative to the rear housing 210 along the guide grooves 212, and the cooperation between the guide posts 520 and the guide grooves 212 restricts the travel distance of the movable locking rod 510.

[0046] Furthermore, the guide post 520 uses a grommet screw, which passes through the connecting hole of the movable locking rod 510 and the guide groove 212 and is threadedly connected to the guide seat 540.

[0047] See Figure 7 and Figure 8 The system also includes a mounting frame 60, which is U-shaped and has insertion channels 610 on its left and right sides. The guide post 520 is at least partially inserted into the insertion channel 610. In this embodiment, the mounting frame 60 is used for wall mounting. When the access control controller is wall-mounted, the mounting frame 60 is fixed to the wall, and then the access control controller is assembled with the mounting frame 60 from top to bottom, allowing the guide post 520 to be inserted into the insertion channel 610. This assembly restricts the access control controller's forward and backward movement, left and right movement, and downward movement.

[0048] See Figure 7 The mounting frame 60 is provided with mounting holes 600. The purpose of the mounting holes 600 is to facilitate the insertion of screws, which then fix the mounting frame 60 to the wall.

[0049] See Figure 8 The rotating shaft 40 is at least partially inserted into the insertion channel 610. This design is intended to improve the connection stability between the access controller and the mounting frame 60.

[0050] See Figure 2 The display module 10 includes a mounting housing 110 and a display screen 120 disposed within the mounting housing 110.

[0051] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
