DETAILED DESCRIPTION
[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.
[0023] Please refer to Figs. 1 to 3 In the embodiment, an intelligent access control machine with a protection mechanism comprises a body 1, a display screen 2 arranged on the front of the body 1, a protection assembly 3 arranged in the body 1, and an unlocking assembly 4 arranged in the body 1.
[0024] The protection assembly 3 comprises an unlocking compartment 31 arranged on the front of the body 1, a protection plate 32 arranged in the unlocking compartment 31, a protection motor 33 fixedly installed in the body 1, a lifting screw 34 fixedly installed on the top of the output shaft of the protection motor 33, and a main control module 35 fixedly installed on the inner side wall of the body 1.
[0025] In the embodiment, the inner side wall of the unlocking compartment 31 is provided with a limiting sliding groove 36 extending into the body 1, and the bottom of the protection plate 32 vertically penetrates the inner top wall of the unlocking compartment 31 to the inside of the unlocking compartment 31 along the limiting sliding groove 36.
[0026] The protection plate 32 is arranged to wrap and protect the unlocking compartment 31, thereby increasing the protection of the unlocking identification module in the unlocking compartment 31.
[0027] In the embodiment, the protection plate 32 is of an L-shaped structure and is provided with a threaded hole at the top, and the lifting screw 34 vertically penetrates the top of the protection plate 32 and is rotatably connected with the protection plate 32 through the threaded hole.
[0028] In this embodiment, a buzzer alarm 37 and a communication microphone 38 are installed inside the unlocking compartment 31. The buzzer alarm 37 and the communication microphone 38 are electrically connected to the main control module 35.
[0029] The unlocking component 4 includes a fingerprint recognition module 41 disposed inside the unlocking compartment 31, a face recognition module 42 fixedly installed on the inner wall of the unlocking compartment 31, a numeric unlocking keypad 43 movably connected to the bottom wall of the body 1, an unlocking motor 44 fixedly installed on the inner side wall of the body 1, and an adjusting screw 45 fixedly installed at the bottom of the unlocking motor 44.
[0030] In this embodiment, the front of the unlocking compartment 31 is provided with several control buttons 39, and the front of the unlocking compartment 31 is provided with a sliding groove 46. The fingerprint recognition module 41 extends horizontally through the sliding groove 46 into the interior of the body 1 and is slidably connected to the inner side wall of the sliding groove 46.
[0031] In this embodiment, a slot is provided at the bottom of the body 1, and the digital unlock keypad 43 passes vertically through the slot and is slidably connected to the bottom wall of the body 1.
[0032] In this embodiment, the side top limit block of the digital unlock keypad 43 has a threaded hole inside, and the adjusting screw 45 has a vertical threaded hole and is rotatably connected to the limit block through the thread.
[0033] In this embodiment, the top of the lifting screw 34 and the bottom of the adjusting screw 45 are rotatably connected to the inner top wall and inner bottom wall of the machine body 1, respectively.
[0034] The working principle of the above embodiments is as follows:
[0035] By clicking the display screen 2, the main control module 35 is activated to start the protective motor 33 to rotate, which drives the lifting screw 34 to rotate. The lifting screw 34 rotates in the threaded hole at the top of the protective plate 32, causing the protective plate 32 to rise. The protective plate 32 causes the unlocking compartment 31 to fully unfold. After clicking the control button 39, the main control module 35 activates the face recognition module 42 to perform face recognition. If face recognition fails, the buzzer alarm 37 sounds an alarm. Then, the fingerprint recognition module 41 is used for recognition.
[0036] In addition, the main control module 35 starts the unlocking motor 44 to rotate, which drives the adjusting screw 45 to rotate. The rotation of the adjusting screw 45 causes the numeric unlocking keypad 43 to extend out of the machine body 1. The user enters a password using the numeric unlocking keypad 43 to unlock the device. After authentication, the main control module 35 controls the unlocking motor 44 to retract the numeric unlocking keypad 43 into the machine body 1. At the same time, it controls the protective motor 33 to lower the protective plate 32 to protect the unlocking chamber 31. This solves the problem that access control devices without a protective mechanism are prone to reduced sensitivity and malfunction after long-term use.
[0037] It should be noted that the fingerprint recognition module 41 and the face recognition module 42 are existing structures. All electrical components mentioned in the text are electrically connected to the main controller and power supply. The main controller can be a conventional known device such as a computer that performs control. The existing publicly available power connection technology will not be described in detail in the text.
[0038] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
[0039] 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.
