Description

Technical Field

[0001] This utility model relates to the field of monitoring equipment technology, and in particular to an elevator car camera with anti-theft function. Background Technology

[0002] Currently, elevator cars are typically equipped with cameras. Traditionally, these cameras are fixed inside the car using screws or adhesive. Screws can damage the car's structure and may harm its load-bearing components, while adhesive, though simple, is difficult to disassemble, repair, or replace. Therefore, many existing cameras are now magnetically attached to the elevator car. These cameras are extremely easy to install and remove, requiring no tools. However, the ease of removal also makes them vulnerable to theft.

[0003] Therefore, existing technologies still need to be improved and enhanced. Utility Model Content

At this time, the alarm is in a de-energized state. When the mounting base is removed from the elevator car, the spring contracts and returns to its natural state, causing the magnetic suction assembly to move so that both ends of the magnetic suction assembly are electrically connected to the power supply component and the alarm, respectively, to provide power.

It also includes: a power supply component disposed within the mounting base and electrically connected to the spherical camera; an alarm disposed within the mounting base; a spring disposed within the mounting base, with one end of the spring fixedly connected to the interior of the mounting base; and a magnetic attraction component disposed within the mounting base and having conductivity, with one side of the magnetic attraction component fixedly connected to the other end of the spring. When the mounting base is attached to the elevator car, the magnetic attraction component is attracted by the elevator car and causes the spring to stretch, thereby adsorbing and fixing the mounting base to the elevator car. At this time, the alarm is in a de-energized state. When the mounting base is removed from the elevator car, the spring contracts and returns to its natural state, causing the magnetic attraction component to move so that both ends of the magnetic attraction component are electrically connected to the power supply component and the alarm, respectively, to provide power.

[0034] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0035] Example:

[0036] Please see Figures 1-7The elevator car camera with anti-theft function includes a mounting base 1 and a spherical camera 2 rotatably mounted on the mounting base 1. It also includes: a power supply component 3, which is disposed within the mounting base 1 and electrically connected to the spherical camera 2; an alarm 4, which is disposed within the mounting base 1; a spring 5, which is disposed within the mounting base 1, with one end of the spring 5 fixedly connected to the interior of the mounting base 1; and a magnetic attraction component 6, which is disposed within the mounting base 1 and has conductive properties. The magnetic attraction component 6 is fixedly connected to one end of the spring 5. When the mounting base 1 is attached to the elevator car, the magnetic attraction component 6 is attracted by the elevator car and causes the spring 5 to stretch, so as to attract and fix the mounting base 1 to the elevator car. At this time, the alarm 4 is in a de-energized state. When the mounting base 1 is removed from the elevator car, the spring 5 contracts and returns to its natural state, and drives the magnetic attraction component 6 to move so that both ends of the magnetic attraction component 6 are electrically connected to the power supply component 3 and the alarm 4 respectively to provide power.

[0037] like Figure 1 , Figure 2 and Figure 3As shown, in this embodiment, the rotatable connection between the spherical camera 2 and the mounting base 1 is achieved by direct motor drive or by existing methods such as worm gear transmission. Meanwhile, the mounting base 1 is equipped with a power supply component 3 for power supply, an alarm 4 for alarm, and a magnetic component 6 for controlling the switch of the alarm 4 and enabling the mounting base 1 to be attached to the elevator car. Specifically, the power supply component 3 is electrically connected to the spherical camera 2, and the magnetic component 6 is movably mounted in the mounting base 1 via a spring 5. When the mounting base 1 is not mounted on the elevator car, that is, when the magnetic component 6 is not near any external metal object, both ends of the magnetic component 6 are in contact with the power supply component 3 and the alarm 4 respectively, so as to conduct electricity between the power supply component 3 and the alarm 4, and the spring 5 is not deformed and is in its natural state. When the mounting base 1 is attached to the elevator car, that is, when the magnetic component 6 is near any external metal object, under the action of magnetic force, the magnetic component 6 moves towards the elevator car in the mounting base 1 and stretches the spring 5, so that the mounting base 1 is attached and fixed to the inner wall of the elevator car. At this time, both ends of the magnetic component 6 are separated from the power supply component 3 and the alarm 4, thereby achieving the function of power cut-off. When external personnel disassemble the mounting base 1 again, the magnetic component 6 will retract to its initial position under the pull of the spring 5 after detaching from the elevator car. At this time, the spring 5 will return to its natural state and the two ends of the magnetic component 6 will be reconnected to the power supply component 3 and the alarm 4. The alarm 4 will be powered on and immediately sound an alarm and upload data to the monitoring terminal through the internal wireless communication module to alert the staff of the monitoring terminal, thereby playing a role in theft prevention. This alarm 4 can be any existing alarm device with functions consistent with this utility model.

[0038] Furthermore, the power supply component 3 includes a battery 301 and a first conductive sheet 302. The battery 301 and the spherical camera 2 are electrically connected to the first conductive sheet 302, and one end of the magnetic suction component 6 is used to connect to the first conductive sheet 302. Specifically, the first conductive sheet 302 and the battery 301 are respectively installed in the mounting base 1, and the battery 301 is electrically connected to the first conductive sheet 302. The first conductive sheet 302 is electrically connected to the spherical camera 2 and one end of the magnetic suction component 6 to conduct electricity.

[0039] Furthermore, the elevator car camera with anti-theft function also includes a second conductive sheet 7. The second conductive sheet 7 is disposed in the mounting base 1 and is used to connect the end of the magnetic attraction component 6 away from the first conductive sheet 302. The alarm 4 is electrically connected to the second conductive sheet 7. The second conductive sheet 7 is used to conduct electricity to the magnetic attraction component 6 and the alarm 4.

[0040] like Figure 4As shown, in this embodiment, the magnetic attraction component 6 includes a magnetic stone 601 and an electrical connector 602. The two ends of the spring 5 are respectively connected to the interior of the mounting base 1 and one side of the magnetic stone 601. The two ends of the magnetic stone 601 are respectively provided with the electrical connector 602, which are used to electrically connect to the first conductive sheet 302 and the second conductive sheet 7, respectively. Specifically, one end of the spring 5 is fixedly connected to the interior of the mounting base 1, and the other end of the spring 5 is fixedly connected to the magnetic stone 601. When the magnetic stone 601 extends into the elevator car, it causes the spring 5 to deform. When the mounting base 1 is removed from the elevator car, the magnetic attraction between the magnetic stone 601 and the elevator car is lost. At this time, the spring 5 recovers its deformation and causes the magnetic stone 601 to retract to its initial position, and the electrical connectors 602 at both ends will contact and energize the first conductive sheet 302 and the second conductive sheet 7, respectively.

[0041] Furthermore, the mounting base 1 includes a housing 101 and a base plate 102. The spherical camera 2 is rotatably disposed inside one side of the housing 101. The power supply component 3, the alarm 4, and the magnetic attraction component 6 are respectively disposed inside the other side of the housing 101. The base plate 102 is detachably connected to the housing 101 and is used to cover the other side of the housing 101, so as to facilitate the disassembly and maintenance of the power supply component 3, the alarm 4, and the magnetic attraction component 6 inside the housing 101.

[0042] like Figure 5 and Figure 6 As shown, further, the other side of the housing 101 is provided with a first mounting groove 1011, a second mounting groove 1012, a third mounting groove 1013, and a fourth mounting groove 1014; the first mounting groove 1011 is connected to the second mounting groove 1012, the second mounting groove 1012 is connected to the third mounting groove 1013, and the third mounting groove 1013 is connected to the fourth mounting groove 1014; the battery 301 and the first conductive sheet 302 are disposed in the first mounting groove 1011, the electromagnet 601, the spring 5, and the electrical connector 602 are respectively disposed in the second mounting groove 1012, the second conductive sheet 7 is disposed in the third mounting groove 1013, and the alarm 4 is disposed in the fourth mounting groove 1014. Specifically, the end of the first conductive sheet 302 is connected to the electrical connector 602 at one end of the electromagnet 601 at the connection between the first mounting groove 1011 and the second mounting groove 1012. The electrical connector 602 at the other end of the electromagnet 601 is connected to one end of the second conductive sheet 7 at the connection between the second mounting groove 1012 and the third mounting groove 1013. The second conductive sheet 7 is connected to the alarm 4 at the connection between the third mounting groove 1013 and the fourth mounting groove 1014.

[0043] Meanwhile, in this embodiment, the housing 101 has two second mounting slots 1012, which are symmetrically arranged on the other side of the housing 101. Each of the two second mounting slots 1012 contains a magnetic assembly. The left magnetic assembly connects to the left end of the first conductive sheet 302 and the left end of the second conductive sheet 7, while the right magnetic assembly connects to the right end of the first conductive sheet 302 and the right end of the second conductive sheet 7. The two magnetic assemblies, the first conductive sheet 302, the second conductive sheet 7, and the alarm 4 form an electrical circuit. In this embodiment, the mounting base 1 is attracted to the elevator car by two conductive magnets 601, which helps to enhance the connection stability of the mounting base 1.

[0044] In this embodiment, a circular groove 1015 is also provided in the second mounting groove 1012, and the spring 5 is fixedly disposed in the circular groove 1015. Specifically, one end of the spring 5 is fixedly connected to the bottom of the circular groove 1015, and the other end of the spring 5 is fixedly connected to one side of the electromagnet 601. The circular groove 1015 plays a limiting and guiding role for the spring 5.

[0045] Furthermore, the second mounting groove 1012 has guide grooves 1016 at both ends, which are formed along the extension and retraction direction of the spring 5. The magnetic attraction assembly 6 also includes sliders 603. The magnetic magnet 601 has sliders 603 at both ends, and the electrical connectors 602 at both ends of the magnetic magnet 601 are respectively and correspondingly mounted on the sliders 603 at both ends. The sliders 603 are slidably mounted in the guide grooves 1016. The guide grooves 1016 guide and limit the sliders 603, preventing the magnetic magnet 601 from deviating during the attraction process.

[0046] Furthermore, a threaded groove 1017 is provided on the other side of the housing 101, and a threaded protrusion (not shown) is provided on the inner side of the base plate 102. The base plate 102 and the housing 101 are screwed together by the combination of the threaded protrusion and the threaded groove 1017. Specifically, when the mounting base 1 is installed on the elevator car, the conductive magnet 601 stretches the spring 5 and abuts against the inner side of the base plate 102. When the mounting base 1 is removed from the elevator car, the conductive magnet 601 is pulled back to its initial position by the spring 5. At this time, there is a gap between the conductive magnet 601 and the inner side of the base plate 102, and the inner side of the base plate 102 abuts against the battery 301 and the alarm 4 to reinforce the battery 301 and the alarm 4.

[0047] like Figure 7As shown, in this embodiment, the elevator car camera with anti-theft function also includes a transparent protective cover 8. The transparent protective cover 8 is disposed on one side of the housing 101 and is used to cover the spherical camera 2. Specifically, the end of the transparent protective cover 8 near the housing 101 may be provided with an internal thread, and the side of the housing 101 near the transparent protective cover 8 may be provided with an external thread. The transparent protective cover 8 is threadedly connected to the housing 101 to facilitate disassembly and cleaning.

[0048] In summary, this utility model embodiment provides an elevator car camera with anti-theft function, which includes a mounting base 1 and a spherical camera 2 rotatably mounted on the mounting base 1. It also includes: a power supply component 3, which is disposed within the mounting base 1 and electrically connected to the spherical camera 2; an alarm 4, which is disposed within the mounting base 1; and a spring 5, which is disposed within the mounting base 1, with one end of the spring 5 connected to the mounting base 1. The mounting base 1 is internally fixedly connected to a magnetic suction component 6, which is disposed within the mounting base 1 and is conductive. One side of the magnetic suction component 6 is fixedly connected to the other end of the spring 5. When the mounting base 1 is attached to the elevator car, the magnetic suction component 6 is attracted by the elevator car and causes the spring 5 to stretch, thereby adsorbing and fixing the mounting base 1 onto the elevator car. At this time, the alarm 4 is in a de-energized state. When the mounting base 1 is removed from the elevator car, the spring 5 contracts and returns to its natural state, causing the magnetic suction component 6 to move so that both ends of the magnetic suction component 6 are electrically connected to the power supply component 3 and the alarm 4 respectively to provide power. In this invention, when the mounting base 1 is attached to the elevator car, the magnetic component 6 is attracted by the elevator car and attaches the mounting base 1 to the elevator car. At this time, the alarm 4 is in a de-energized state, and the spring 5 is in a stretched state. When the mounting base 1 is removed from the elevator car, the spring 5 returns to its original shape and drives the magnetic component 6 back to its initial position. At this time, both ends of the magnetic component 6 are electrically connected to the power supply component 3 and the alarm 4 respectively and begin to conduct electricity. After the alarm 4 is powered on, it begins to send an alarm to the outside world. After the alarm 4 is powered on, it will upload data to the monitoring terminal through the internal wireless communication module to alert the staff of the monitoring terminal, thereby playing a role in theft prevention.
