[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figures 1 to 8 As shown, a smart door with an anti-disassembly alarm function proposed in this embodiment includes a smart door body 1 and a host 100 embedded in one side of the smart door body 1, the host 100 includes a lower cover 3 embedded and fixed on one side of the smart door body 1, one side of the lower cover 3 is movably in contact with an upper cover 2, one side of the upper cover 2 and the inner wall of the lower cover 3 are fixedly connected with an elastic quick-clip assembly, and the elastic quick-clip assembly is used for convenient clamping and assembling of the upper cover 2 and the lower cover 3;

[0025] A main board 4 is fixedly installed on one side of the upper cover 2, and two conductive spring clips 5 that are in active contact with the smart door body 1 and are in a taut state are welded and fixed to the bottom of one side of the main board 4. The conductive spring clips 5 are bent at the contact position with the smart door body 1, and the two conductive spring clips 5 are interference fit with the smart door body 1. An embedding hole fixedly connected to the outer side of the lower cover 3 is opened on one side of the smart door body 1, and a conductor that is in active contact with the side of the conductive spring clip 5 is fixedly connected to the inner wall of the embedding hole.

[0026] Specifically, a groove 7 is formed at the bottom of one side of the lower cover 3 , and the two conductive springs 5 ​​are in active contact with the side wall of the groove 7 .

[0027] Furthermore, the elastic quick card assembly includes a block 9, one side of which is set as an inclined surface, and the top inner wall, bottom inner wall, front inner wall and rear inner wall of the lower cover 3 are respectively fixedly connected to the corresponding multiple blocks 9, and the four sides of the upper cover 2 close to the lower cover 3 are fixedly connected with L-shaped elastic clamping rods 8, and the side walls of the L-shaped elastic clamping rods 8 are in active contact with the corresponding side of the block 9 away from the upper cover 2, and the side of the L-shaped elastic clamping rod 8 away from the upper cover 2 is set as an inclined section, and the inclined section is adapted to the corresponding inclined surface; the set block 9, inclined surface, L-shaped elastic clamping rod 8 and inclined section cooperate, and when the upper cover 2 is pushed in the direction close to the door body 1 of the smart door, the upper cover 2 drives the inclined sections of the multiple L-shaped elastic clamping rods 8 to squeeze the inclined surfaces of the multiple blocks 9, and under the extrusion force, one end of the L-shaped elastic clamping rod 8 automatically displaces and automatically rebounds and resets to engage with the block 9 when it is staggered from the corresponding block 9, so that the upper cover 2 is conveniently and quickly engaged and fixed, and there is no need to add a separate bracket for fixing, which reduces the installation time and cost.

[0028] Furthermore, a plurality of elastic walls 6 are fixedly connected to the top of the upper cover 2 close to the smart door body 1. The upper cover 2 is interference fit with the smart door body 1 through the elastic walls 6. The preferred thickness of the elastic walls 6 is to ensure that it will not be easily ejected after assembly.

[0029] Furthermore, the conductive spring 5 is made of spring steel that is heat-treated and nickel-plated.

[0030] Furthermore, an anti-disassembly detection chip and a judgment chip are provided on the main board 4. Two conductive spring clips 5 welded on the main board 4 are respectively connected to the signal pins of the judgment chip and the anti-disassembly detection chip. When not connected to the smart door body 1, the two conductive spring clips 5 are independent of each other. When connected to the smart door body 1, the two conductive spring clips 5 form an electrical connection between the two conductive spring clips 5 by contacting with the smart door body 1; when connected to the smart door body 1, since there is an electrical connection between the conductive spring clips 5 of the judgment chip on the main board 4 and the conductive spring clips of the anti-disassembly detection chip, the level of the anti-disassembly detection chip is pulled to a low level. At this time, it is judged that the device is normally connected to the smart door body 1. When the device is dismantled, the level of the signal pin of the anti-disassembly detection chip changes to a high level. At this time, the system judges that the device is abnormally dismantled and triggers an alarm signal. The friction between the host and the smart door body 1 is enhanced through the interference fit of the conductive spring clips 5, which can not only enhance the reliability of the host 100 after installation, but also realize the anti-disassembly alarm function.

[0031] Furthermore, the pin position of the mainboard 4 where the conductive spring clip 5 is welded is electrically connected to one end of the first resistor R672, and the other end of the first resistor R672 is electrically connected to one end of the second resistor R308, one end of the third resistor R310 and one end of the TVS tube TVS13, and the other end of the TVS tube TVS13 is grounded. The conductive spring clip 5 connected to the judgment chip is electrically connected to one end of the capacitor C638 and one end of the fourth resistor R671, and the other end of the capacitor C638 and the other end of the fourth resistor R671 are both grounded; in order to prevent the interference signal from directly entering the signal pin of the anti-dismantling detection chip when it is interfered by static electricity, the TVS tube TVS13 is added to the position where the conductive spring clip 5 is welded on the mainboard 4 to increase pin protection, and the series resistance formed by the first resistor R672, the second resistor R308 and the third resistor R310 is added to the signal pin to increase the wire impedance on the signal pin to ensure that the interference signal directly enters the judgment chip when it is guided to the device through the smart door body 1, and does not enter the signal pin of the anti-dismantling detection chip to cause abnormal operation of the device.

[0032] The method of using this embodiment is as follows: before the upper cover 2 is installed, the conductive spring sheet 5 is in an untensioned and mutually independent state. When the upper cover 2 is installed, when the upper cover 2 is pushed toward the direction close to the door body 1 of the smart door, the upper cover 2 drives the inclined cross sections of the multiple L-shaped elastic clamping rods 8 to squeeze the inclined surfaces of the multiple stoppers 9. Under the squeezing force, one end of the L-shaped elastic clamping rod 8 automatically moves and automatically rebounds and resets to engage with the stopper 9 when it is offset from the corresponding stopper 9. By using the automatic clamping method of the elastic member when pushing, the upper cover 2 is conveniently and quickly clamped and fixed, without the need to add a separate bracket for fixing, which reduces the installation time and cost, and solves the problem of high precision requirements and poor reliability of the traditional anti-disassembly method.

[0033] When the upper cover 2 is pushed and connected, the main board 4 is also driven to move. The main board 4 drives the two conductive spring pieces 5 to squeeze and deform with the lower cover 3 and tighten. The two conductive spring pieces 5 are in contact with the smart door body 1. At this time, the two conductive spring pieces 5 are in contact with the smart door body 1 to form an electrical connection between the two conductive spring pieces 5. When the smart door body 1 is connected, since there is an electrical connection between the conductive spring piece 5 of the judgment chip on the main board 4 and the conductive spring piece of the anti-disassembly detection chip, the level of the anti-disassembly detection chip is pulled to a low level. At this time, it is judged that the device is normally connected to the smart door body 1. When the device is dismantled, the level of the signal pin of the anti-disassembly detection chip changes to a high level. At this time, the system judges that the device is abnormally dismantled and triggers an alarm signal. The friction between the host and the smart door body 1 is enhanced through the interference fit of the conductive spring piece 5, and the reliability of the host 100 after installation is enhanced. The conductive performance and deformation performance of the conductive spring piece 5 are utilized to facilitate the contact between the conductive spring piece 5 and the smart door body 1 to achieve the anti-disassembly alarm function while ensuring the integrity of the appearance.

[0034] In addition, in order to prevent the interference signal from directly entering the signal pin of the anti-dismantling detection chip due to electrostatic interference, a TVS tube TVS13 is added at the position where the conductive spring 5 is welded on the main board 4 to increase pin protection, and a series resistor formed by a first resistor R672, a second resistor R308 and a third resistor R310 is added to the signal pin to increase the wire impedance on the signal pin to ensure that the interference signal directly enters the judgment chip when it is guided to the device through the smart door body 1, and does not enter the signal pin of the anti-dismantling detection chip, causing abnormal operation of the device.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein with equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
