Technical Field

[0001] The utility model relates to an optical delivery box lock in the field of mobile communication equipment, which is a highly waterproof optical delivery box lock. Background Art

[0002] Currently, optical delivery locks have a promising future, primarily driven by the rapid development of the communications industry and the increasing demand for intelligent management. Furthermore, with the widespread adoption of new services such as mobile internet, the total number of optical delivery locks is rapidly increasing, and traditional management methods are no longer able to meet the demands of modern communications operations. The widespread adoption and application of smart locks can effectively address real-time monitoring and management of operational status. Currently, these smart locks on the market offer features such as remote unlocking, vibration / pry / key unlocking, but they generally face waterproofing issues. There are two main types of optical delivery locks on the market: One type is a traditional mechanical lock, the most basic type used in optical delivery locks, typically used for basic theft prevention. However, this type of lock has a simple structure and requires a key for opening, making it suitable for most basic security needs. The other type offers features such as remote unlocking, vibration / pry / key unlocking, but only meets standard IP65 waterproofing and rust resistance. In terms of structure, the above two types of locks are either not smart locks or their waterproofness cannot meet the requirements; for this reason, some locks combine the above-mentioned optical delivery box locks and smart lock functions, such as the application number 201910043189.5 disclosed in the Chinese patent literature, the authorization announcement date is 2021.04.09, and the utility model name is "universal optical delivery box smart lock"; however, this type of smart lock is less used in optical delivery box locks.

[0026] Based on the above structural features, the optical delivery lock includes a separate motor drive waterproof mechanism module design and the entire PCB mainboard and wake-up button are designed using a glue potting solution, which is as follows:

[0027] 1) A separate motor drive waterproof mechanism module is designed to drive the lock tongue through motor drive. The bevel gear A and bevel gear B gearboxes are built into separate housings. The motor is also waterproof. Bevel gear A, which extends beyond the motor, is sealed with a sealing ring. This standard design prevents water from entering the motor. This waterproof mechanism module can be used even for short periods of time when submerged in water. The advantages of this waterproof motor drive structure are as follows: 1. The motor is waterproofed using glue potting; 2. The bevel gear drive is protected by a separate motor drive waterproof mechanism module; 3. The bevel gear and motor drive are isolated by a sealing ring for waterproofing; and 4. The entire motor drive is waterproofed using the motor drive waterproof mechanism module.

[0028] 2) The entire PCB motherboard and wake-up button are designed with a glue filling solution, which effectively protects the motherboard from moisture, dust and corrosion, and extends the service life of the motherboard. Glue filling improves stability, fixes electronic components, prevents the influence of vibration and impact on the motherboard, and ensures the stability of the motherboard. Glue filling increases insulation and has excellent insulation performance, prevents circuit short circuits, and improves the safety of the motherboard. In addition, glue filling improves shock resistance and absorbs vibrations, reducing the impact of the external environment on the motherboard. The advantages of the waterproof glue filling solution structure of the above-mentioned whole machine are as follows: 1. The mainboard and motor transmission waterproof mechanism module adopt glue filling waterproofing method; 2. The bevel gear and motor transmission adopt a sealing membrane group waterproof isolation structure; 3. The speaker waterproof adopts a waterproof and sound-permeable membrane solution; 4. The extended lock tongue adopts an EVA pad waterproof isolation solution; 5. The transmission mechanism of the whole machine adopts a module waterproof glue filling fixation method.

[0029] When using the optical cross-box lock, open the dust cover on the handle assembly and insert the electronic key; rotate the electronic key 90 degrees forward to unlock the lock, and rotate it 90 degrees counterclockwise to lock the lock. The optical cross-box lock detects the motor pulse output interrupt method to unlock the lock as follows: 1. The motor pulse output is detected using an interrupt method, and the motor power switch uses the IO output high and low level method to control the MOS tube to control the motor power supply. 2. The system determines whether the motor is in place by detecting the interrupt count value. When the motor is in place, the count value is reset to zero and the motor power switch is set to the off state. After the system is powered on / reset, the pulse count value is reset to 0 and the motor power switch is set to the on state.

[0030] Currently, there's no seal between the metal backplate and the door panel of a light-transfer lock, allowing water to flow through the gap and accumulate on the back of the lock. This accumulation of water can lead to water seeping into the lock through the screw holes on the back, soaking the internal circuit board and motor for extended periods, rendering the lock inoperable. Existing similar products employ the following conventional waterproofing technologies: 1. Using a sealing ring for the motor drive mechanism; 2. Using a sealing ring for the entire lock; 3. Using a drainage groove and a separate motor structure. However, these approaches struggle to achieve or meet IP68 waterproofing requirements.

[0031] To this end, the motor waterproofing scheme of the aforementioned optical cross-box lock is specifically structured as follows: 1. The motor is waterproofed using glue potting; 2. The bevel gear transmission is protected by an independent waterproof module; 3. The bevel gear and motor transmission are isolated by a sealing ring for waterproofing; 4. The entire motor transmission adopts a modular waterproof structure. The entire optical cross-box lock adopts a waterproof glue potting scheme specifically structured as follows: 1. The mainboard and motor module are waterproofed using glue potting; 2. The bevel gear and motor transmission adopt a sealed membrane for waterproofing; 3. The speaker is waterproofed using a waterproof and sound-permeable membrane solution; 4. The extended lock tongue is waterproofed using an EVA padding solution; 5. The entire transmission mechanism is secured by modular waterproofing and glue potting. At the same time, the specific structure and advantages of the above-mentioned optical cross-box lock are as follows: 1. The motor transmission casing is filled with glue and then the wires are left out; 2. The whole machine transmission adopts a modular waterproof structure. There is no similar structure on the market. This structure is relatively novel; 3. The motor is protected by the casing and then filled with glue; 4. The main board and the motor module are waterproofed by the whole glue filling method; 5. It has the advantages of simple structure and good production stability; 6. The waterproofing of the speaker adopts a simple sound-transparent waterproof membrane solution.
