Description

Anti-tamper locking mechanism and electronic device

technical field

The utility model provides an anti-disassembly locking mechanism and an electronic device, in particular to an anti-disassembly locking mechanism and an electronic device that can be assembled quickly and prevent easy disassembly.

Background technique

The current electronic products are all covered with casings to protect the components inside the casings from being damaged by external forces and cannot be used normally. Generally speaking, after the electronic components are placed in the case during the production process, the case will be processed to be assembled and fixed. Furthermore, the user usually does not need to disassemble the casing by himself after purchasing the electronic product. Therefore, securing the enclosures together properly is one of the most important parts of the production process.

For example, please refer to FIG. 1A and FIG. 1B , FIG. 1A is a schematic diagram of a known electronic device 10 , and FIG. 1B is a diagram of components of the electronic device 10 . If the electronic device 10 is a power converter (adapter), as shown in FIGS. 1A and 1B , the electronic device 10 includes a first casing 100 and a second casing 102 . In the production process, after the relevant circuit components and connectors are assembled on the first housing 100 or the second housing 102, they will be processed and assembled to lock the first housing 100 and the second housing 102 Together, in this way, the protection of the casing will prevent the components inside the casing from being damaged by external forces. On the other hand, during the charging process, properly fixing the casing can also protect the user from the danger of electric shock. Therefore, the casing is properly fixed by processing during the production process.

The traditional processing and assembling method is to fix the first casing 100 and the second casing 102 so that they cannot be disassembled by adhesive bonding or ultrasonic welding. However, the method using ultrasonic welding requires special equipment and takes a long time for installation. As for the method of adhesive bonding, it also needs a period of time to wait for the adhesive to dry, which requires a long waiting time for assembly, and even the adhesive will deteriorate as the product is used for a long time, so that the first shell and the second shell The body cannot be fixedly engaged and falls off, which increases the possibility of damage to the electronic device.

Therefore, how to provide an anti-dismantle locking mechanism so that the electronic device can be firmly combined for a long time, can save processing time and program and processing equipment costs during the assembly process, and at the same time can avoid the case of the shell falling off due to long-term use, It is a problem that relevant industry players urgently need to solve together.

Therefore, it is necessary to provide an anti-tamper locking mechanism and an electronic device to solve the above problems.

Detailed ways

Please refer to FIG. 2A and FIG. 2B. FIG. 2A is a component diagram of an electronic device 20 according to an embodiment of the present invention, and FIG. 2B is a schematic diagram of an anti-tamper locking mechanism according to an embodiment of the present invention. The electronic device 20 includes a first casing 200 , a second casing 202 and at least one anti-tamper locking mechanism 204 . Wherein, the anti-tampering locking mechanism 204 includes an engaging member 2040 , guiding grooves 2044 , 2046 and an engaging clasp 2048 . The engaging part 2040 is disposed on the first housing 200 , and the engaging part 2040 includes an engaging hole 2042 . The engaging hole 2042 is located in the engaging member 2040 to form a hole. The locking hole 2042 corresponds to the locking hook 2048 . For example, the locking hole 2042 and the bottom surface of the locking hook 2048 have approximately the same shape and area, so that the locking hook 2048 can be locked into the locking hole 2042 . The guiding grooves 2044 , 2046 and the locking hook 2048 are disposed on the second housing 202 , and the locking hook 2048 is located between the guiding grooves 2044 , 2046 .

Please refer to FIG. 3A and FIG. 3B . FIG. 3A is a schematic diagram of the electronic device 20 assembled via the anti-tamper locking mechanism 204 , and FIG. 3B is a side cross-sectional view of the electronic device 20 assembled via the anti-tamper locking mechanism 204 . When assembling, after aligning the engaging part 2040 with the two guiding grooves 2044 and 2046 , push it toward the bottom of the second housing 202 . Wherein, the engaging member 2040 and/or the engaging hook 2048 are made of elastic material, such as elastic plastic. The locking hook 2048 has an inclined surface 2050 , and the inclined surface 2050 faces a direction to be engaged with the first casing 200 . When the engaging piece 2040 is pushed toward the bottom of the second housing 202 along the two guide grooves 2044, 2046, due to the action of the slope 2050 of the engaging buckle 2048, the engaging piece has a direction perpendicular to the second housing. 202 is lifted in the lateral direction, and since the guide grooves 2044 and 2046 have clamped the engaging part 2040, the engaging part 2040 will not fall off. At the same time, because the engaging member 2040 and/or the engaging clasp 2048 are made of elastic material, the engaging member 2040 and/or the engaging clasp 2048 are pressed against the guide groove 2044, 2046 clamps to produce elastic deformation until it continues to advance to the end section of the inclined surface 2050 beyond the snap hook 2048, and the snap part 2040 and/or the snap hook 2048 makes the snap hole 2042 just fit with the snap due to elastic recovery. The clasp hook 2048 is fastened. In this case, as shown in FIG. 4A and FIG. 4B , after the engaging part 2040 is fastened, it is blocked by the two guide grooves 2044, 2046 and the engaging buckle 2048, and the engaging part 2040 cannot be disengaged in any direction. , so as to fix the first shell and the second shell.

In short, when assembling, as long as the engaging piece 2040 is inserted into the two guide grooves 2044, 2046, push hard to allow the engaging piece 2040 and/or the buckle hook 2048 to be elastically deformed, and then they can be snapped together. The purpose of simple and fast assembly can be realized. Furthermore, since the anti-tamper locking mechanism 204 is located inside the electronic device 20 after assembly, and the engaging member 2040 will be clamped by the guiding grooves 2044, 2046, it is not easy for the user to engage the engaging clasp 2048 Disengaging from the engaging hole 2042 prevents the user from disassembling the electronic device 20 at will. In this case, if the first shell 200 is to be separated from the second shell 202 , it may be necessary to use an external force to forcibly pry the shell apart to destroy the engaging member 2040 . Therefore, the anti-disassembly locking mechanism of the present invention is very suitable for one-time installation and fixing of electronic devices.

It should be noted that the purpose of the electronic device 20 is only for demonstration and not limited thereto, and the present invention can be applied to any casing of a one-time fixed electronic device. Meanwhile, those skilled in the art should be able to make various changes accordingly. For example, as shown in FIG. 2A and FIG. 2B , four anti-tampering locking mechanisms 204 are taken as an example to connect and fix the first housing 200 and the second housing 202 , but not limited thereto. The location and quantity of the anti-tampering locking mechanism 204 should be configured in different ways according to design requirements.

In summary, the housing of the electronic device of the present invention uses the built-in tamper-resistant locking mechanism to fix the first housing and the second housing, which can save additional equipment costs and assembly waiting time in assembly, and at the same time be tamper-resistant. The locking mechanism has permanent fixation, which can prevent the shell from falling off due to the deterioration of the adhesive, thereby prolonging the service life of the electronic device.

The above descriptions are only preferred embodiments of the present utility model, and all equivalent changes and modifications made according to the scope of the claims of the present utility model shall fall within the scope of the present utility model.
