Description

Technical Field

[0001] This utility model relates to the field of smart door lock technology, specifically to a smart door lock with a sealed and waterproof structure. Background Technology

[0002] With the booming development of the smart home industry, smart door locks have become standard equipment in modern homes and commercial venues due to their convenience, security and intelligent management functions. However, with the diversification of application scenarios, common smart door locks have insufficient waterproofing for the climate in the south. During the "return to spring" weather in the south, moisture can easily seep into the interior through weak points such as door lock gaps, button holes and biometric modules, causing short circuits in the circuit board and corrosion of electronic components, thus affecting the service life of the door lock. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an intelligent door lock with a sealed and waterproof structure, which has advantages such as improved waterproofing and sealing performance, and solves the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a smart door lock with a sealed and waterproof structure, comprising a panel and a back cover, wherein the back cover comprises a battery compartment and a cover hinged to the inner wall of the battery compartment, the panel comprises a mounting groove formed on its surface, a display module fixedly mounted on the inner wall of the mounting groove, and a handle rotatably connected to the side of the panel. The inner bottom wall of the mounting slot has two conical drainage channels. The two drainage channels pass through the two sides of the panel along the width direction. An electrostatic waterproof sticker is attached to the connection between the mounting slot and the display module. The inner wall of the battery compartment is stepped, and an L-shaped sealing ring is installed inside the battery compartment. A rectangular extrusion piece is fixedly connected to the cover on one side of the battery compartment. The end of the extrusion piece facing the battery compartment has an arc-shaped chamfer and contacts the sealing ring. A fixing component is provided between the battery compartment cover and the battery compartment to secure the battery compartment cover.

[0005] Furthermore, a sealing ring three is provided on one side of the panel corresponding to the back cover, and the sealing ring three is interference-fitted with the display module.

[0006] The above solution allows the sealing ring three to form a tight seal with the display module through an interference fit, preventing water from seeping in from the connection between the panel and the mounting groove, as well as around the display module.

[0007] Furthermore, the panel and the back cover are both fitted with sealing rings two by interference fit on one side, and the two sealing rings are both provided with slots on one side, and pressure frames are inserted into the inside of the two slots.

[0008] With the above solution, the second sealing ring can be squeezed by the contact between the pressure frame and the door body when the panel or back cover is installed on the door body, thereby enhancing the sealing performance between the panel or back cover and the door body.

[0009] Furthermore, a sealing ring is fitted onto the circumferential surface of the handle shaft along its axial direction, and a threaded groove is provided on the circumferential surface of the handle shaft. A pressure ring that contacts the sealing ring is threadedly connected to the threaded groove of the handle shaft.

[0010] The above solution prevents water from entering the smart lock from the handle shaft by fitting the sealing ring onto it. The pressure ring is connected by threads to squeeze the sealing ring, making the sealing ring fit tightly against the handle shaft and enhancing the sealing effect.

[0011] Furthermore, the circumferential surface of the pressure ring is hexagonal.

[0012] With the above solution, the circumferential surface of the pressure ring is hexagonal, which makes it easy for users to install and remove the pressure ring using external tools.

[0013] Furthermore, a placement frame is fixedly connected to one side of the battery compartment cover.

[0014] The above solution involves filling the inside of the placement frame with a desiccant. The desiccant absorbs moisture in the battery compartment, keeping the inside of the battery compartment dry and preventing damage to batteries and other electronic components due to moisture.

[0015] Furthermore, the fixing component includes a groove opened in the inner wall of the battery compartment, and a shaped part is fixedly connected to one side of the compartment cover facing the rear shell, with one end of the shaped part located in the groove being U-shaped.

[0016] The above solution uses an elastic plastic material for the irregularly shaped parts. When installing and removing the cover, the U-shaped end can undergo elastic deformation, making it easy for the irregularly shaped parts to be inserted into or removed from the groove.

[0017] Furthermore, a triangular slot is provided on the side of the irregular part away from the compartment cover, and a triangular block is fixedly connected to the inner wall of the slot, with the block located inside the slot.

[0018] Through the above scheme, the combination of the triangular slot and the locking block can make the connection between the irregular part and the groove more stable. When subjected to external force, the triangular structure can better disperse the stress and prevent the irregular part from falling out of the groove.

[0019] Compared with the prior art, the technical solution of this utility model has the following beneficial effects: This smart door lock features a sealed and waterproof structure. A drainage channel guides water into the mounting slot, preventing water accumulation and damage to the display module. A waterproof electrostatic sticker seals the connection between the display module and the mounting slot, preventing moisture from seeping in and enhancing waterproofing. Secondly, the stepped inner wall works in conjunction with an L-shaped sealing ring. When the cover is closed, the compression component presses the sealing ring, ensuring tight contact and improving the battery compartment's seal. Finally, a second sealing ring is pressed against the door frame when the panel or back cover is installed, further enhancing the seal between the panel / back cover and the door.

[0024] The inner bottom wall of the mounting groove 101 has two conical drainage grooves 3, which pass through the two sides of the panel 1 along the width direction. An electrostatic waterproof sticker 4 is attached to the connection between the mounting groove 101 and the display module 102. The drainage grooves 3 can effectively guide the water entering the mounting groove 101 to drain out, avoiding water accumulation that could damage the display module 102. The electrostatic waterproof sticker 4 can further prevent moisture from seeping in from the connection gap between the mounting groove 101 and the display module 102, thus enhancing the waterproof effect.

[0025] The inner wall of the battery compartment 201 is stepped, and an L-shaped sealing ring 5 is installed inside the battery compartment 201. A rectangular extrusion member 6 is fixedly connected to the cover 202 on one side of the battery compartment 201. The end of the extrusion member 6 facing the battery compartment 201 has an arc-shaped chamfer and contacts the sealing ring 5. The stepped inner wall and the L-shaped sealing ring 5 cooperate to increase the contact area between the sealing ring 5 and the battery compartment 201 and improve the sealing performance. The arc-shaped chamfer of the extrusion member 6 can make the extrusion member 6 contact the sealing ring 5 more smoothly and squeeze the sealing ring 5 to ensure the sealing effect.

[0026] A fixing component 7 is provided between the cover 202 and the battery compartment 201 to fix the cover 202. The fixing component 7 can firmly fix the cover 202 to the battery compartment 201 to prevent the seal from failing due to the cover 202 loosening.

[0027] A sealing ring 3 8 is provided on one side of the panel 1 corresponding to the back cover 2. The sealing ring 3 8 is interference-fitted with the display module 102. The interference fit between the sealing ring 3 8 and the display module 102 can form a tight seal to prevent water from seeping in from the connection between the panel 1 and the mounting groove 101 and around the display module 102. A sealing ring 2 9 is also interference-fitted on one side of the panel 1 and the back cover 2. A slot 10 is opened on one side of each of the two sealing rings. A pressure frame 11 is inserted into the inside of each slot 10. When the panel 1 or the back cover 2 is installed on the door, the sealing ring 2 9 can be squeezed by the contact between the pressure frame 11 and the door, thereby enhancing the sealing between the panel 1 or the back cover 2 and the door. A sealing ring 12 is fitted on the circumferential surface of the handle 103 shaft along its axial direction. The handle 103 shaft has a threaded groove 13, and a pressure ring 14 is threadedly connected to the threaded groove 13, which contacts the sealing ring 12. The sealing ring 12 is fitted onto the handle 103 shaft to prevent water from entering the smart lock from the handle 103 shaft. The pressure ring 14 is threaded to squeeze the sealing ring 12, making the sealing ring 12 fit tightly against the handle 103 shaft, enhancing the sealing effect. The circumferential surface of the pressure ring 14 is hexagonal, which makes it easy for users to install and remove the pressure ring 14 using external tools. The cover 202 is located on one side of the battery compartment 201 and is fixedly connected to a placement frame 15. The inside of the placement frame 15 is filled with desiccant, which can absorb moisture in the battery compartment 201, keep the inside of the battery compartment 201 dry, and prevent moisture damage to batteries and other electronic components.

[0028] The fixing component 7 includes a groove 701 formed in the inner wall of the battery compartment 201. A shaped part 702 is fixedly connected to the side of the compartment cover 202 facing the rear shell 2. One end of the shaped part 702 located in the groove 701 is U-shaped. The shaped part 702 is made of elastic plastic. When installing and removing the compartment cover 202, the U-shaped end can undergo elastic deformation, which makes it easy for the shaped part 702 to be inserted into or removed from the groove 701. A triangular slot 703 is formed on the side of the shaped part 702 away from the compartment cover 202. A triangular block 704 is fixedly connected to the inner wall of the groove 701. The block 704 is located in the slot 703. The triangular slot 703 and the block 704 cooperate to make the connection between the shaped part 702 and the groove 701 more stable. When subjected to external force, the triangular structure can better disperse stress and prevent the shaped part 702 from falling out of the groove 701.

[0029] The working principle of the above embodiment is as follows: First, when the panel 1 and the back shell 2 are installed on the door panel, the two pressure frames 11 will contact the door panel and squeeze the corresponding sealing ring 9 after being subjected to force, so that the two sealing rings 9 can make tight contact with the panel 1 and the back shell 2 respectively, thereby improving the sealing performance. The drainage groove 3 set at the mounting groove 101 can guide and discharge the water in the mounting groove 101 when rain splashes, preventing water accumulation at the mounting groove 101 and the display module 102. The interference fit sealing ring 8 can seal the display module 102, preventing water from seeping in through the gap between the display module 102 and the mounting groove 101. The cooperation between the sealing ring 12 and the pressure ring 14 can make the sealing ring 12 tightly connected with the handle 103 shaft and the panel 1 through the pressure ring 14 squeezing the sealing ring 12, thereby improving the waterproofness of the handle 103. When the weather is humid, moisture can easily seep into the gap between the battery compartment 201 and the cover 202, affecting the normal operation of the internal parts. When the cover 202 is closed, the pressing member 6 on the cover 202 can press the sealing ring 5, so that the sealing ring 5 can maintain a tight contact with the pressing member 6. In addition, the placement frame 15 on the cover 202 is filled with desiccant, which can absorb the moisture in the battery compartment 201 and keep the battery compartment 201 dry. When the battery compartment 201 is closed, the irregular part 702 can enter the groove 701 and the locking block 704 can enter the slot 703 to lock the cover 202 and keep the battery compartment 201 sealed.
