Description

Electronic device and its number of times of disassembly

The present invention relates to a detachable device, and more particularly to a detachable electronic device and a method of recording the number of times of disassembly.

At present, all new electronic products will have a product quality warranty period. Each merchant will stipulate that during the product warranty period, only qualified personnel can disassemble or repair the product. However, many consumers find that the product has failed during the warranty period of the product, and send the product to the repair department designated by the manufacturer or open the product for repair. If it is not repaired, it will be sent to the manufacturer's designated warranty unit. repair. Since the product has been opened and repaired by a person without maintenance qualification, it may have become a serious failure. But consumers sometimes don't take the initiative to admit that they have opened the product without authorization.

In order to distinguish whether the product has been dismantled, the tamper-evident seal is generally marked on the corresponding part for opening or not. However, when the tamper-evident seal is not destroyed by man-made during disassembly, the consumer often cannot prove his innocence. Such problems can lead to disputes between consumers and businesses.

In view of this, it is necessary to provide an electronic device that accurately identifies whether or not it is removed.

It is also necessary to provide a method of recording the number of times of disassembly of an electronic device.

An electronic device assembled from a plurality of components, the electronic device further comprising: a photosensitive element, a processing element, and a storage element mounted on the interior thereof; the photosensitive element is configured to receive light and achieve a preset intensity at a received light intensity The trigger signal is generated; the processing component is configured to convert the trigger signal into a digital message of the number of times the at least one component of the plurality of component assemblies is unpacked, and is saved in the storage component.

A method for recording the number of times of disassembly of an electronic device, comprising the steps of: receiving light by a photosensitive element inside the electronic device, and generating a trigger signal when the received light intensity reaches a preset intensity; converting the number of times the trigger signal is generated into a digital position The message is stored in a storage element inside the electronic device.

The electronic device and the method for recording the number of times of disassembly thereof convert the plurality of component separation operations of the electronic device into data information storage, so as to provide accurate and valid proof for subsequent determination whether the electronic device is disassembled.

As shown in FIG. 1 , it is a perspective structural view of an electronic device 100 in a preferred embodiment. The electronic device 100 in the present embodiment is a mobile phone, which includes an upper cover 102 and a lower cover 104. Please refer to FIG. 2 together, which is an internal structural diagram of the electronic device 100. The electronic device 100 further includes a light-emitting element 202, a light-sensitive element 204, a processing element 206, and a storage element 208 mounted on the lower cover 104.

Light-emitting element 202 is used to emit light of a particular spectrum, such as infrared light. When the upper cover 102 and the lower cover 104 of the electronic device 100 are closed, the light reaches the photosensitive member 204 based on the reflection of the upper cover 102.

The photosensitive element 204 is configured to receive external light and generate a trigger signal when the received light of the specific spectrum is less than a preset intensity. Referring to FIG. 3 at the same time, under normal circumstances, the upper cover 102 and the lower cover 104 of the electronic device 100 are in the closed state, and the photosensitive member 204 receives the light reflected by the upper cover 102. When the upper cover 102 and the lower cover 104 of the electronic device 100 are opened, the light emitted by the light-emitting element 202 cannot be transmitted to the photosensitive member 204. At this time, the photosensitive member 204 generates a trigger signal indicating that the upper cover 102 is opened.

The processing component 206 is configured to convert the trigger signal into a digital message indicating the number of times the upper cover 102 and the lower cover 104 are opened, and is stored in the storage element 208. That is, each time the light sensitive element 204 generates a trigger signal, the processing element 206 increments the number of open times stored in the storage element 208 by one, and the initial number of open times is zero.

The light emission of the light-emitting element 202 and the photoelectric conversion action of the light-sensitive element 204 can be It is performed according to a preset frequency. For example, the light-emitting element 202 emits light every 30 seconds or one minute, and the photosensitive element 204 also performs photoelectric conversion for thirty seconds or one minute. In other embodiments, the light-emitting element 202 can also be mounted on the upper cover 102. At this time, the light emitted by the light-emitting element 202 can be directly emitted onto the photosensitive element 204 without being reflected, and the upper cover 102 and the lower cover 104 are opened by the photosensitive element 204. The trigger signal is generated because the light is no longer received.

As shown in FIG. 4, it is a method for recording the number of times of disassembling an electronic device according to a preferred embodiment, which includes the following steps:

Step S801, emitting light of a specific spectrum based on the light emitting elements inside the electronic device.

Step S802, receiving light of the specific spectrum by a photosensitive element inside the electronic device, and generating a trigger signal when the received light of the specific spectrum is less than a preset intensity.

In step S803, the number of times the trigger signal is generated is converted into a digital message and stored in a storage element inside the electronic device.

The disassembly operation can be automatically recorded by the above-described removal method of the electronic device. In the event of a conflict, the data message can be called out as evidence, avoiding unnecessary disputes between consumers and merchants.

Referring to FIG. 5, an electronic device 200 is different from the electronic device 100 described above in that the electronic device 200 omits the light-emitting element 202, and the photosensitive element 204' is used to replace the photosensitive element 204 in the electronic device 100. The photosensitive element 204' It is used to detect the ambient light intensity and generate a trigger signal when it detects that the light intensity reaches the preset intensity. In this manner, the number of times of disassembly of the electronic device 200 can also be recorded.

As shown in FIG. 6, it is a record of the number of times of disassembly of the electronic device of another preferred embodiment. The method includes the following steps:

In step S901, a photosensitive element is disposed inside the electronic device, and ambient light is received by the photosensitive element.

Step S902, when the light intensity received by the photosensitive element reaches a preset intensity, a trigger signal is generated.

In step S903, the number of times the trigger signal is generated is converted into a digital message and stored in a storage element inside the electronic device.

In the instant mode of the above two electronic devices and the method for recording the number of times of disassembly, the common feature is that the photosensitive device generates a trigger signal when the received light change amount reaches a preset change amount, thereby determining that the electronic device is disassembled. .

It is to be understood by those skilled in the art that the above embodiments are only intended to illustrate the invention, and are not intended to limit the invention, as long as it is within the spirit of the invention Changes and modifications are intended to fall within the scope of the invention.
