Description

Technical Field

[0001] This utility model relates to the field of smart lock technology, and in particular to a smart lock display screen with automatic defogging. Background Technology

[0002] The lock body of a smart lock is divided into two parts, which are located on the inside and outside of the door respectively. Therefore, the touch screen operation area of ​​a traditional smart lock is directly exposed to the outside. When the outside humidity is high, moisture is easily attached to the surface of the display screen. In the event of strong winds and rain, some rainwater will directly impact the smart lock and thus adhere to the surface of the smart lock's display screen.

[0003] The presence of fog can blur the content on the display screen, making it difficult for users to see operation prompts, password input areas, etc., affecting normal unlocking operations. Furthermore, fog or rainwater adhering to the screen surface can form water droplets or water films, which can interfere with the capacitive sensing of the touch screen, causing abnormal touch signal transmission and resulting in no touch response, delay, or accidental touch. Utility Model Content

[0004] The purpose of this invention is to provide an intelligent lock display screen with automatic defogging, which can effectively solve the problems in the background technology.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An automatic defogging smart lock display screen includes a front lock body. A front handle is movably mounted on the front side of the front lock body. A touch screen is fixedly mounted on the front lock body above the front handle. A fingerprint recognition module is also fixedly mounted on the front lock body between the front handle and the touch screen. The touch screen and the fingerprint recognition module are electrically connected to the main control board inside the front lock body via cables. Slide grooves are provided on both sides of the front lock body. A limiting piece is movably mounted on the top of the front lock body. A protective cover is movably mounted between the two slide grooves and located on the front side of the touch screen. An installation groove is provided inside the protective cover. A first moisture-absorbing box is fixedly mounted on one side of the installation groove. A second moisture-absorbing box is fixedly mounted on one side of the first moisture-absorbing box. A stop rod is fixedly mounted on the protective cover on both sides of the first moisture-absorbing box. A base is fixedly mounted on the bottom of the protective cover. A scraper is fixedly mounted on one side of the base.

[0007] As a further preferred embodiment of this utility model, the first moisture-absorbing box body has multiple air holes on one side, the second moisture-absorbing box body has a snap-fit ​​groove on one side, and the second moisture-absorbing box body passes through the mounting groove and is snapped onto the first moisture-absorbing box body. The enclosed space of the first and second moisture-absorbing box bodies is filled with desiccant. The protective cover makes the touch screen display screen a relatively closed space. With the desiccant in the first and second moisture-absorbing box bodies, the moisture content in the protective cover can be reduced, the probability of pre-cooling liquefaction can be reduced, and thus the generation of fog on the surface of the touch screen display screen can be reduced.

[0008] As a further preferred embodiment of this utility model, two positioning grooves are provided on one side of the abutment rod, and sliders are fixedly installed on both sides of the inner side of the protective cover. The sliders are slidably installed in one of the grooves, and one side of the abutment rod abuts against one side of the limiting plate. The limiting plate is installed in the groove at the top of the front lock body of the lock by a torsion spring, so that the protective cover slides vertically on the front side of the touch screen by the internal slider, so that one side of the limiting plate abuts against one side of the abutment rod and is locked in the corresponding positioning groove, thereby realizing the opening and closing positioning action of the protective cover on the front side of the touch screen.

[0009] As a further preferred embodiment of this utility model, a connecting groove is provided at the bottom of the protective cover. The connecting groove is provided to realize the assembly of the base and facilitate the disassembly and maintenance of the scraper.

[0010] As a further preferred embodiment of this utility model, two first connecting blocks are fixedly installed on one side of the base. A slot is provided on one side of the first connecting block. The slot on one side of the first connecting block can provide basic conditions for the installation of the scraper. A second connecting block is fixedly installed on the top of the base. The second connecting block is inserted into the connecting slot and fixed with screws.

[0011] As a further preferred embodiment of this utility model, multiple guide grooves are provided on both sides of the base. The guide grooves can guide and discharge the droplets formed by the scraper scraping water mist off the surface of the touch screen.

[0012] As a further preferred embodiment of this utility model, a water-blocking rod is fixedly installed on one side of the scraper. The scraper has an inverted V-shaped structure, and one side of the water-blocking rod is fitted into two slots. The side of the scraper away from the slots abuts against the surface of the touch screen. When the protective cover is opened to operate the touch screen, the protective cover can move the scraper upward, automatically scraping away and guiding the mist on the surface of the touch screen. This, together with the desiccant in the first and second moisture-absorbing boxes, enables the automatic removal of mist from the surface of the touch screen when operating it.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In this invention, a sliding protective cover is provided on the front side of the touch screen to protect the touch screen and keep it in a relatively enclosed environment. This, combined with the desiccant in the first and second moisture-absorbing boxes, reduces the humidity inside the protective cover, thereby reducing condensation on the touch screen surface and preventing external rainwater from adhering to it. Furthermore, a base is provided at the bottom of the protective cover, with a scraper on one side. This scraper automatically removes condensation from the touch screen surface when the protective cover is opened and the touch screen is operated, compensating for insufficient desiccant in the protective cover and the first and second moisture-absorbing boxes, which could otherwise cause condensation on the touch screen and affect operation.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figures 1-6As shown, this utility model provides an automatic defogging smart lock display screen, including a front lock body 1, a front handle 2 movably mounted on the front side of the front lock body 1, a touch screen 3 fixedly mounted above the front handle 2, and a fingerprint recognition module 4 fixedly mounted between the front handle 2 and the touch screen 3. The touch screen 3 and the fingerprint recognition module 4 are electrically connected to the main control board inside the front lock body 1 via cables. The front lock body 1 also has additional features located on both sides of the touch screen 3. Each lock has a sliding groove 5. A limiting piece 6 is movably installed on the top of the front lock body 1. A protective cover 7 is movably installed between the two sliding grooves 5 and is located in front of the touch screen 3. An installation groove 8 is provided inside the protective cover 7. A first moisture-absorbing box 9 is fixedly installed on one side of the installation groove 8. A second moisture-absorbing box 10 is fixedly installed on one side of the first moisture-absorbing box 9. A stop rod 11 is also fixedly installed on both sides of the protective cover 7. A base 12 is fixedly installed at the bottom of the protective cover 7. A scraper 13 is fixedly installed on one side of the base 12.

[0024] like Figures 2-3 As shown, the first moisture-absorbing box 9 has multiple air holes on one side, and the second moisture-absorbing box 10 has a snap-fit ​​groove 14 on one side. The second moisture-absorbing box 10 passes through the mounting groove 8 and is snapped onto the first moisture-absorbing box 9. The enclosed space of the first moisture-absorbing box 9 and the second moisture-absorbing box 10 is filled with desiccant. The protective cover 7 makes the touch screen 3 in a relatively closed space. With the desiccant in the first moisture-absorbing box 9 and the second moisture-absorbing box 10, the moisture content in the protective cover 7 can be reduced, the probability of pre-cooling liquefaction can be reduced, and thus the generation of fog on the surface of the touch screen 3 can be reduced.

[0025] like Figures 2-6As shown, two positioning grooves 15 are provided on one side of the abutment rod 11. Slider blocks 16 are fixedly installed on both sides of the inner side of the protective cover 7. The sliders 16 are slidably installed in one of the grooves 5. One side of the abutment rod 11 abuts against one side of the limiting piece 6. The limiting piece 6 is installed in the groove at the top of the front lock body 1 of the lock via a torsion spring, allowing the protective cover 7 to slide vertically on the front side of the touch screen 3 via the internal sliders 16. This causes one side of the limiting piece 6 to abut against one side of the abutment rod 11 and be locked in the corresponding positioning groove 15, thus realizing the opening and closing positioning action of the protective cover 7 on the front side of the touch screen 3. A connecting groove 17 is provided at the bottom of the protective cover 7. The connecting groove 17 is used to assemble the base 12, facilitating the disassembly and maintenance of the scraper 13. Two first connecting blocks 19 are fixedly installed on one side of the base 12. A slot 20 is provided on one side of the first connecting block 19, which allows for the installation of the scraper 13. The base 12 provides basic conditions. A second connecting block 21 is fixedly installed on the top of the base 12. The second connecting block 21 is inserted into the connecting groove 17 and fixed with screws. Multiple guide grooves 18 are opened on both sides of the base 12. The opening of the guide grooves 18 can guide and discharge the droplets formed by the scraper 13 scraping water mist off the surface of the touch screen 3. A water baffle 22 is fixedly installed on one side of the scraper 13. The scraper 13 has an inverted V-shaped structure. One side of the water baffle 22 is stuck in two slots 20. The side of the scraper 13 away from the slots 20 abuts against the surface of the touch screen 3. When the protective cover 7 is opened to operate the touch screen 3, the protective cover 7 can move the scraper 13 upward, and automatically scrape and guide the water mist on the surface of the touch screen 3 through the scraper 13. In this way, in conjunction with the desiccant in the first moisture-absorbing box 9 and the second moisture-absorbing box 10, the water mist on the surface of the touch screen 3 can be automatically scraped off when the touch screen 3 is operated.

[0026] It should be noted that this utility model is an automatic defogging smart lock display screen. A slidable protective cover 7 is provided on the outside of the touch screen 3 on the front side of the lock body 1. It moves in the slide groove 5 by a slider 16. When opening and closing, it is positioned by the positioning groove 15 of the limiting piece 6 and the abutment rod 11. Furthermore, a desiccant is placed in the first moisture-absorbing box 9 and the second moisture-absorbing box 10. Multiple air holes are opened on one side of the first moisture-absorbing box 9. Thus, when the protective cover 7 protects the touch screen 3 in a relatively closed space, it can absorb the water vapor in the space inside the protective cover 7, so that the touch screen 3 is in a low-humidity closed environment, reducing the probability of water vapor condensing into fog when it encounters cold.

[0027] Additionally, when the ambient humidity is high, if a layer of condensation still appears on the surface of the touchscreen display 3, the user needs to open the protective cover 7 before operating the touchscreen display 3. Specifically, when the user needs to operate the touchscreen display 3, the protective cover 7 is slid up to open, and the scraper 13 on the base 12 at the bottom will move upwards simultaneously. The scraper 13 is in an inverted V-shape and presses against the surface of the touchscreen display 3 to remove the condensation. The removed droplets are discharged through the drainage channel 18 inside the base 12, preventing liquid accumulation. This allows the condensation on the surface of the touchscreen display 3 to be cleaned simultaneously with opening the protective cover 7, without affecting the user's normal touch operation of the touchscreen display 3.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
