Description

Technical Field

[0001] This utility model relates to the field of smart door lock technology, specifically a panel with a surface protection structure. Background Technology

[0002] Smart locks are upgraded products of traditional mechanical locks that integrate IoT and biometric technologies. They can be unlocked through multiple methods such as passwords, fingerprints, and mobile apps. Smart locks consist of four main modules: the recognition module (including fingerprint modules and keypads) which acts as the "eyes" and is responsible for identity verification; the control module (main control chip and circuit board) which acts as the "brain" and receives signals to determine whether to unlock; the execution module (motor and lock body) which acts as the "hands" and completes the physical unlocking action; and the power supply and communication module which provides energy and supports networking functions such as Bluetooth and Wi-Fi. The four modules work together to achieve a convenient and secure user experience. Among them, the fingerprint module, keypad, and other recognition modules are usually integrated into the display panel.

[0003] Smart locks typically have sliding covers to protect the display panel. These covers can be manual or electric. Manual covers require manual opening and closing, which is inconvenient and can sometimes leave the display panel unprotected if it is forgotten to be closed. Electric covers open and close automatically using motors and other components, but they are more expensive and have a higher failure rate than manual covers. This problem has not been solved in the current technology. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-6 This utility model provides a technical solution:

[0027] A panel with a surface protection structure includes a smart lock body, the smart lock body includes an outer shell 12, a handle 13 is rotatably mounted at the lower center of the outer shell 12, a display panel 14 is mounted on the top of the outer shell 12, and a protective cover 1 is disposed on the outside of the display panel 14 and slides in cooperation with the outer shell 12.

[0028] By setting the outer casing 12, installation support and external protection can be provided for all internal structures to ensure stable operation of components; the handle 13 is the physical unlocking operation component, which can be linked with the lock cylinder to complete the door opening action when turned; the display panel 14 integrates fingerprint module, password key and other recognition modules, and is the key interaction area for users to authenticate and trigger unlocking commands.

[0029] It also includes a protective cover plate 1, on the inner side of which two sets of guide seats 2 are symmetrically installed. The guide seats 2 slide in conjunction with the grooves 3 opened on both sides of the top of the outer shell 12.

[0030] By setting a protective cover 1, the display panel 14 can be protected. The protective cover 1 slides and engages with the sliding groove 3 of the outer shell 12 through two sets of guide seats 2 on the inner side, which can flexibly cover or expose the display panel 14. The core function of the protective cover 1 is to isolate external damage such as dust, oil, and bumps, and to prevent the identification components on the display panel 14 from malfunctioning due to dirt or physical contact. At the same time, covering the display panel 14 when not in use can also reduce the risk of accidental touch and information exposure, and improve the durability and security of the smart lock.

[0031] The system also includes an opening assembly, which comprises a guide rod 4 and a first spring 5. The guide rod 4 is fixedly installed in the slide groove 3, and the first spring 5 is slidably sleeved on the surface of the guide rod 4. The top of the first spring 5 abuts against the guide seat 2, and the bottom of the first spring 5 abuts against the bottom of the slide groove 3. The opening assembly also includes a hook seat 15, which is slidably installed in the mounting groove 16 opened in the middle of the outer shell 12. The bottom of the protective cover plate 1 has a hook groove 17 that cooperates with the hook seat 15. A pressing post 18 is fixedly installed on one side of the hook seat 15, and one side of the pressing post 18 extends out of the outer shell 12. The pressing post 18 is slidably engaged with the outer shell 12. A pushing post 19 is fixedly installed on the other side of the hook seat 15. One side of the pushing post 19 abuts against one side of the second spring 20, and the other side of the second spring 20 abuts against the inner wall of the outer shell 12. The pushing post 19 and the second spring 20 are slidably engaged with the inside of the outer shell 12.

[0032] By setting an opening component, the protective cover 1 can be automatically opened. The opening component mainly consists of a guide rod 4, a first spring 5, a hook seat 15, a pressing post 18, and a second spring 20. The guide rod 4 cooperates with the first spring 5 to provide the protective cover 1 with the upward force to open. Normally, the first spring 5 is in a compressed state and is locked by the engagement of the hook seat 15 with the hook groove 17 at the bottom of the protective cover 1. When the user presses the pressing post 18 that extends out of the outer shell 12, the hook seat 15 will compress the second spring 20 and disengage from the hook groove 17. The first spring 5 releases its elastic force and pushes the protective cover 1 to slide upward along the slide groove 3, automatically opening to expose the display panel 14.

[0033] It also includes a closing assembly, which includes a rack 7. The top of the rack 7 is fixedly connected to a guide seat 2 on one side of the protective cover. The bottom of the rack 7 meshes with a gear 8. An adjustment groove 9 is provided in the middle of the gear 8. A slide rod 10 is fixedly installed inside the adjustment groove 9. The slide rod 10 is slidably engaged with the drive shaft 11. The adjustment groove 9 is slidably engaged with the drive shaft 11. A third spring 21 is slidably sleeved on the surface of the slide rod 10. One end of the third spring 21 abuts against the drive shaft 11, and the other end of the third spring 21 abuts against the inner wall of the adjustment groove 9. One end of the drive shaft 11 is connected to a handle 13, and the other end of the drive shaft 11 is connected to a lock cylinder. A pusher 6 for pushing the gear 8 is fixedly installed at the bottom of the hook seat 15. The pusher 6 is located between the rack 7 and the gear 8 and is slidably engaged with the inside of the outer shell 12.

[0034] The closing component is designed to automatically close the protective cover 1 after the user opens the door. Key components of the closing component include a rack 7, a gear 8, a drive shaft 11, a slide rod 10, and a third spring 21, and it is linked to the handle 13. The top of the rack 7 is fixed to the guide seat 2 on one side of the protective cover 1, and its bottom engages with the gear 8. When the protective cover 1 needs to be opened, pressing the push column 19 causes the hook seat 15 to move and disengage from the hook groove 17. Simultaneously, the hook seat 15 drives the push frame 6 to move, which in turn pushes the gear 8 to move and compresses the third spring 21, thereby disengaging the gear 8 from the rack 7 and preventing the meshing state of the gear 8 and rack 7 from affecting the rack 7 and slide rod. The seat and protective cover move upward; the gear 8 cooperates with the transmission shaft 11 of the connecting handle 13 through the adjustment groove 9 and the slide rod 10. Normally, the third spring 21 will push the gear 8 to mesh with the rack 7. When the user turns the handle 13 to open the anti-theft door after successfully unlocking using the display panel 14, the handle 13 drives the gear 8 to rotate through the transmission shaft 11 and the slide rod 10, causing the rack 7 meshing with the gear 8 to move downward. The rack 7 pulls the slide seat downward, driving the protective cover to move downward until the hook groove 17 engages with the hook seat 15, thereby closing the protective cover. Finally, it re-engages with the hook seat 15 to lock, achieving automatic closing without the need for separate manual operation.

[0035] In practical use, the device is installed in the corresponding position on the security door. When the smart lock needs to be unlocked, the pressing post 18 extending from the outside of the outer shell 12 is pressed by hand. The pressing post 18 will push the hook seat 15 to slide in the mounting groove 16. The pushing post 19 on one side of the hook seat 15 compresses the second spring 20 until the hook seat 15 disengages from the hook groove 17 at the bottom of the protective cover plate 1. At this time, the first spring 5 sleeved on the surface of the guide rod 4 in the slide groove 3 is no longer constrained, and the released elastic force pushes the guide seat 2 to slide upward along the slide groove 3. The guide seat 2 drives the protective cover plate 1 to move upward synchronously, gradually revealing the display panel 14 on the top of the outer shell 12. The user can complete the identity verification through the fingerprint module, password button, etc. on the display panel 14. After the identity verification is successful and the lock is unlocked, the outer shell 12 is rotated. The handle 13 at the bottom of the housing 12 opens the door. When the handle 13 is turned, it drives the gear 8 to rotate as well. Since the third spring 21 pushes the gear 8 to keep it engaged with the rack 7, the rotation of the gear 8 will drive the rack 7 to move downward. The top of the rack 7 is fixed to the guide seat 2, which in turn pulls the guide seat 2 to slide downward along the slide groove 3. The guide seat 2 drives the protective cover 1 to fall down. When the protective cover 1 falls to the initial position, the pushed hook seat 15 slides in the opposite direction under the return force of the second spring 20 and re-engages with the hook groove 17 at the bottom of the protective cover 1, locking the protective cover 1. At this time, the display panel 14 is covered again, completing a complete operation process from opening the protective cover 1 to automatically closing the protective cover 1 after unlocking.
