Description

Technical Field

[0001] This utility model belongs to the field of lock technology, and specifically relates to a lock. Background Technology

[0002] With the continuous development of smart home and smart security technologies, electronic locks are widely used in homes, offices, hotels, and many other fields due to their convenience and security. To help users understand the operating status of electronic locks, such as unlocking, locking, and low battery reminders, existing electronic locks typically have an internal sound-emitting device. This device transmits sound to the outside through a sound outlet to alert the user to the current status of the electronic lock.

[0003] However, existing electronic lock sound-emitting structures have several problems. Firstly, the sound outlet is directly exposed to the external environment, making the electronic lock susceptible to external factors during use. For example, rainwater, dust, and other debris may enter the electronic lock through the sound outlet, damaging internal electronic components such as circuit boards, sound-emitting chips, and sensors. This damage not only shortens the lifespan of the electronic lock but also reduces its reliability, causing inconvenience and safety hazards for users. Especially under severe weather conditions, such as heavy rain or sandstorms, the failure rate of electronic locks increases significantly, seriously affecting their normal use.

[0004] On the other hand, to improve the waterproof performance of electronic locks, existing technologies employ a sealed design. While this can prevent moisture and dust from entering the lock to some extent, it also introduces new problems. The sealed structure hinders the effective propagation of sound, leading to a decrease in sound quality. For example, the sound may become muffled, weak, or even inaudible to the user. This undoubtedly affects the user experience, especially in noisy environments, where users may be unable to accurately judge the status of the electronic lock, causing inconvenience. Furthermore, some electronic locks may increase sound power to improve sound quality, but this not only increases energy consumption but may also cause the internal temperature of the electronic lock to rise, further affecting the lifespan of electronic components.

[0005] Therefore, existing technologies present an irreconcilable contradiction between waterproof performance and sound quality. On the one hand, sealing the design for waterproofing reduces sound quality; on the other hand, exposing the sound outlet to ensure sound quality weakens waterproof performance. Furthermore, some existing solutions, such as increasing sound power, while alleviating the problem to some extent, also introduce new issues such as increased energy consumption and shortened component lifespan. Therefore, how to ensure both waterproof performance and good sound quality in electronic locks without increasing additional energy consumption and component burden is a pressing technical problem that needs to be solved. Utility Model Content

[0006] The primary objective of this invention is to provide a lock that solves at least one of the aforementioned problems.

[0007] To achieve the various objectives of this utility model, the following technical solution is adopted:

[0008] To achieve one of the objectives of this utility model, a lock is provided, comprising a housing, a speaker, and a rubber pad. The speaker is installed inside the housing, and the housing includes a base plate. The base plate has a sound inlet corresponding to the speaker. The rubber pad is attached to the base plate and has a sound transmission hole corresponding to the sound inlet. A sound outlet is formed on the edge of the rubber pad. The sound transmission hole and the sound outlet are connected to form a sound channel. The sound outlet is located diagonally below the sound transmission hole.

[0009] In one embodiment, the speaker channel includes a main section, a transition section, and an outlet section. The main section is located at the position of the sound transmission hole, the outlet section is configured to communicate with the speaker outlet, and the transition section connects the main section and the outlet section.

[0010] In one embodiment, the main body segment is located diagonally above the exit segment, and the transition segment is a corner structure.

[0011] In one embodiment, along the extension direction of the speaker channel, the width of the main body section is greater than the width of the outlet section, the width of the outlet section is greater than or equal to the width of the transition section, or the width of the speaker channel gradually transitions from wide to narrow from the main body section to the outlet section.

[0012] In one embodiment, the outlet section is provided with a sound guide block, one end of which forms a pointed portion facing the transition section, and the other end forms an expanded portion facing the speaker opening. The width of the sound guide block gradually transitions from narrow to wide from the pointed portion to the expanded portion.

[0013] In one embodiment, the adhesive pad has two sides, the front side of the adhesive pad is attached to the base plate, and the back side of the adhesive pad is recessed towards the front side to form a groove, the groove constituting the sound channel.

[0014] In a further embodiment, the lock is used to be installed on a door panel, the door panel being in contact with the reverse side of the rubber pad to close the groove opening and form a channel.

[0015] In one embodiment, the groove includes a bottom wall and two side walls disposed on both sides of the bottom wall, the side walls protruding relative to the opposite side to form a surrounding bone structure.

[0016] In one embodiment, a channel is formed within the rubber pad, and the channel constitutes the sound channel.

[0017] In one embodiment, a waterproof membrane is further provided between the rubber pad and the base plate, and the waterproof membrane is disposed between the sound inlet and the sound outlet.

[0018] Compared with the prior art, this utility model has many advantages, including but not limited to:

[0019] This lock design utilizes gravity by positioning the speaker opening diagonally below the sound transmission hole. This prevents water droplets or dust from flowing back into the sound transmission hole, even if they enter the speaker opening, thus effectively preventing them from entering the housing. Furthermore, the rubber gasket further isolates the external environment from the housing interior, preventing moisture or dust from directly contacting the sound transmission hole, significantly improving the lock's waterproof performance and extending its service life.

[0020] Existing technologies employing sealed designs for waterproofing can hinder sound propagation, leading to a decline in sound quality. This invention addresses this issue by incorporating a sound-emitting channel. This allows sound emitted from the speaker to be projected sequentially through the sound inlet, sound outlet, sound channel, and sound port. This not only prevents sound from being directly blocked by the outer shell and rubber pads but also concentrates and guides the sound through the sound channel, resulting in clearer and louder sound transmission and improved user experience. Especially in noisy environments, users can accurately identify the sound emitted by the speaker, resolving the problem of poor sound quality in existing technologies.

[0021] The lock's speaker is positioned on the edge of the rubber pad. This not only reduces the exposed area of ​​the speaker, decreasing the probability of water droplets or dust entering, but also avoids creating large holes on the lock surface, thus maintaining the overall aesthetic appeal of the lock. At the same time, this structure does not compromise the overall design of the lock, allowing it to achieve good waterproof performance and sound transmission while also possessing a high level of aesthetics, meeting users' requirements for product appearance.

[0022] The lock has a relatively simple structure, mainly achieving its function by setting a sound-guiding hole on the base plate, a sound-transmitting hole and a sound-speaking port on the rubber pad, forming a sound-speaking channel. It does not require complex processes or additional components, making it easy to manufacture and assemble, thus reducing production costs. At the same time, its simple structure also makes the lock more stable and reliable in actual use, reducing the risk of failure caused by complex structures. Attached Figure Description

[0031] This utility model provides a lock 10, combined with Figure 1 and Figure 2The lock 10 includes a housing 100, a speaker (not shown), and a rubber pad 200. The housing 100 is used to house the transmission components and electronic components of the lock 10. The speaker is installed in the housing 100 and is controlled to emit sound. The lock 10 is mounted on one side of a door panel 300.

[0032] Combination Figure 4 The housing 100 is formed by a plurality of shell plates arranged together, one of which is a bottom plate 110, which faces the door panel 300. A sound-guiding hole 120 is provided on the bottom plate 110, penetrating the bottom plate 110. A loudspeaker is positioned corresponding to the sound-guiding hole 120, so that the sound emitted by the loudspeaker is dispersed outward through the sound-guiding hole 120.

[0033] The adhesive pad 200 is disposed outside the housing 100. The adhesive pad 200 includes a front side and a back side 212. The front side of the adhesive pad 200 is attached to the base plate 110. When the lock 10 is installed on the door panel 300, the back side 212 of the adhesive pad 200 is attached to the door panel 300.

[0034] Combination Figure 2 and Figure 3 The rubber pad 200 is provided with a sound transmission hole 220, which corresponds to the sound inlet hole 120 on the base plate 110, so that the sound emitted by the speaker is dispersed to the outside through the sound inlet hole 120 and the sound transmission hole 220 in sequence. A sound outlet 230 is provided on the edge 250 of the rubber pad 200. The sound transmission hole 220 is not provided on the edge 250 of the rubber pad 200. The sound transmission hole 220 and the sound outlet 230 are connected to form a sound channel 240, so that the sound emitted by the speaker is guided to the outside through the sound inlet hole 120, the sound transmission hole 220, the sound channel 240 and the sound outlet 230 in sequence, so that the sound is not blocked by the housing 100 and the rubber pad 200, and the sound emitted by the speaker can be dispersed to the outside well.

[0035] In a typical embodiment of this utility model, the speaker 230 is located diagonally below the sound transmission hole 220. It can be understood that the speaker 230 is also located diagonally below the sound inlet hole 120. In this embodiment, with the door panel 300 vertically arranged, along the vertical direction of the door panel 300, both the sound transmission hole 220 and the sound inlet hole 120 are located diagonally above the speaker 230. When water droplets or dust enter the speaker opening 230, because the speaker opening 230 is located obliquely below the sound transmission hole 220, the water droplets or dust cannot flow back into the sound transmission hole 220. This prevents the water droplets or dust from entering the housing 100 through the sound transmission hole 220 and the sound inlet hole 120, thus avoiding water droplets or dust from corroding the speaker and other electronic components installed in the housing 100. This protects the speaker and various electronic components installed in the housing 100 and extends the service life of the lock 10.

[0036] The speaker 230 is located on the edge 250 of the rubber pad 200 and is positioned diagonally below the sound transmission hole 220, forming a unique waterproof structure. By utilizing gravity, water droplets or dust entering the speaker 230 are difficult to flow backward to the sound transmission hole 220, thereby effectively preventing water droplets or dust from entering the housing 100 and protecting the speaker and other electronic components from corrosion.

[0037] The speaker opening 230 is disposed on the edge 250, so that water droplets or dust cannot easily enter the speaker channel 240 through the speaker opening 230, thereby further preventing water droplets or dust from entering the speaker channel 240 through the speaker opening 230, avoiding blockage of the speaker channel 240, and protecting the lock 10.

[0038] Because the speaker opening 230 is located on the edge 250 of the rubber pad 200, the area of ​​the speaker opening 230 exposed to the outside world is reduced, further reducing the probability of water droplets or dust entering the speaker channel 240, avoiding blockage of the speaker channel 240, and protecting the lock 10. Furthermore, the location of the speaker opening 230 on the edge 250 of the rubber pad 200 does not damage the overall appearance of the lock 10, making the lock 10 more aesthetically pleasing.

[0039] In one embodiment, combined Figure 4The adhesive pad 200 is rectangular, and has two edges along the vertical direction of the door panel 300, namely the upper edge 251 and the lower edge 252; the adhesive pad 200 also has two edges along the width direction of the door panel 300, namely the left edge 253 and the right edge 254. In this embodiment, it is recommended that the speaker opening 230 be disposed on the lower edge 252, the left edge 253, or the right edge 254 of the adhesive pad 200, but this should not be construed as a limitation of this utility model.

[0040] In a typical embodiment of this utility model, combined with Figure 3 The sound channel 240 includes a main body section 241, a transition section 242, and an outlet section 243 connected in sequence. The main body section 241 is positioned corresponding to the location of the sound transmission hole 220, such that the sound transmission hole 220 is connected to the main body section 241. In this embodiment, the sound transmission hole 220 is located at the bottom of the main body section 241 to facilitate its connection. The outlet section 243 is connected to the speaker outlet 230, or the speaker outlet 230 is part of the outlet section 243. The two ends of the transition section 242 are connected to the main body section 241 and the outlet section 243 respectively, thus forming the sound channel 240.

[0041] In this embodiment, since the sound transmission hole 220 is located diagonally above the sound outlet 230, it can be understood that the main body section 241 is located diagonally above the outlet section 243, and the transition section 242 transitionally connects the main body section 241 and the outlet section 243.

[0042] In this embodiment, the transition section 242 is a corner structure. When water droplets or dust enter the outlet section 243, they need to bypass the corner structure of the transition section 242 before moving to the main body section 241 located diagonally above the outlet section 243. This increases the difficulty for water droplets or dust to enter the main body section 241, thereby preventing them from entering the housing 100 through the sound transmission hole 220 and the sound guide hole 120. This also prevents water droplets or dust from corroding the speakers and other electronic components installed in the housing 100, protecting them and extending the service life of the lock 10. Since water droplets or dust are affected by gravity and air resistance during movement, this corner structure of the transition section 242 greatly hinders their reverse movement, thereby further improving the waterproof performance.

[0043] Furthermore, when external moisture enters the transition section 242, because the transition section 242 is a corner structure, the moisture will collide with the side wall of the transition section 242, causing the moisture to condense into water droplets at the transition section 242. Then, due to their own weight, the water droplets will flow to the outlet section 243 and then flow out to the outside. This process not only prevents moisture from entering the main body section 241, but also prevents moisture from accumulating in the sound channel 240, thereby preventing moisture from corroding the speakers and other electronic components installed in the housing 100, protecting the speakers and other electronic components installed in the housing 100, and extending the service life of the lock 10.

[0044] In one embodiment, along the extension direction of the speaker channel 240, the width of the main body section 241 is greater than the width of the outlet section 243, and the width of the outlet section 243 is greater than or equal to the width of the transition section 242. This allows the sound to gradually concentrate within the speaker channel 240 as it disperses along its extension path, thereby improving the clarity and loudness of the sound. Specifically, after the sound emitted by the speaker enters the main body section 241 through the sound inlet 120 and the sound transmission hole 220, the sound gradually concentrates along the main body section 241, the transition section 242, and the outlet section 243 of the speaker channel 240 to improve the sound quality, making the sound emitted from the speaker outlet 230 clearer and louder, thus enhancing the user experience.

[0045] In another embodiment, along the extension direction of the speaker channel 240, the width of the speaker channel 240 gradually transitions from wide to narrow from the main body section 241 to the outlet section 243. That is, the width of the main body section 241, the width of the transition section 242, and the width of the outlet section 243 gradually transition from wide to narrow in sequence, thereby further optimizing the sound propagation path and allowing the sound to be better concentrated during propagation, thus improving the sound quality. Specifically, after the sound emitted by the speaker enters the main body section 241 through the sound inlet 120 and the sound transmission hole 220, the sound gradually concentrates along the main body section 241, the transition section 242, and the outlet section 243 of the speaker channel 240 to improve the sound quality, making the sound emitted from the speaker outlet 230 clearer and louder, thus improving the user experience.

[0046] In a typical embodiment of this utility model, combined with Figure 3The outlet section 243 is provided with a sound guide block 270. One end of the sound guide block 270 forms a pointed portion 271, and the other end forms an expanded portion 272. The pointed portion 271 and the expanded portion 272 gradually transition from narrow to wide. Specifically, the pointed portion 271 has a conical structure, and the expanded portion 272 has a planar structure, a rounded head structure, or an elliptical head structure. Along the width direction of the sound channel 240, the width of the sound guide block 270 gradually transitions from narrow to wide from the pointed portion 271 to the expanded portion 272. In this embodiment, it is recommended that the sound guide block 270 be a triangular block, a conical structure, or a pyramidal structure, but this should not be construed as a limitation of the present invention.

[0047] The sound guide block 270 is disposed in the center of the outlet section 243, with its tip 271 facing the transition section 242 and its expansion portion 272 facing the speaker opening 230. The tip 271 facing the transition section 242 helps to concentrate the sound transmitted from the transition section 242, improving sound quality and making the sound emitted from the speaker opening 230 clearer and louder, thus enhancing the user experience. Specifically, the tip 271 of the sound guide block 270 can effectively collect the sound transmitted from the transition section 242 and guide it to the expansion portion 272, thereby concentrating and optimizing the sound. This not only improves the sound propagation efficiency but also reduces sound scattering and attenuation during propagation, further enhancing the clarity and loudness of the sound.

[0048] A sound guide block 270 is disposed in the outlet section 243, and the expansion portion 272 of the sound guide block 270 is disposed facing the transition section 242. The expansion portion 272 will prevent water droplets or dust from entering the sound channel 240, so that water droplets or dust will not flow back into the main body section 241, thereby preventing water droplets or dust from entering the housing 100 through the sound transmission hole 220 and the sound guide hole 120, preventing water droplets or dust from corroding the speakers and other electronic components installed in the housing 100, protecting the speakers and other electronic components installed in the housing 100, and extending the service life of the lock 10. Specifically, the expansion portion 272 can effectively block the entry of water droplets or dust. Its large surface area and relatively smooth surface can prevent water droplets or dust from accumulating on the surface of the sound guide block 270 and prevent them from flowing back into the sound channel 240, thereby further improving the waterproof performance of the lock 10.

[0049] In a typical embodiment of this utility model, combined with Figures 1 to 4 The lock 10 is installed on the door panel 300, the front of the rubber pad 200 is attached to the base plate 110, and the back 212 of the rubber pad 200 is attached to the door panel 300. Figure 3The back surface 212 of the adhesive pad 200 is provided with a groove 280. The groove 280 is recessed from the back surface 212 toward the front surface. The groove 280 extends along the extension path of the sound channel 240, thereby forming the sound channel 240.

[0050] Combination Figures 1 to 4 When the lock 10 is installed on the door panel 300, the reverse side 212 of the rubber pad 200 is attached to the door panel 300, and the door panel 300 will close the groove 281 of the recess 280 facing the door panel 300, that is, the door panel 300 closes the groove 281 of the recess 280 to form a channel structure. Because the door panel 300 closes the groove 281 of the recess 280, water droplets or dust cannot enter the recess 280 through the groove 281, thereby preventing water droplets or dust from entering the housing 100 through the sound transmission hole 220 and the sound inlet hole 120, preventing water droplets or dust from corroding the speaker and other electronic components installed in the housing 100, protecting the speaker and other electronic components installed in the housing 100, and extending the service life of the lock 10.

[0051] Furthermore, because the door panel 300 closes the slot 281 of the groove 280, the sound emitted by the speaker, after entering the groove 280 through the sound inlet 120 and the sound transmission hole 220, will not radiate outward from the slot 281 of the groove 280. Instead, the sound will be emitted outward along the speaker channel 240 to concentrate the sound and improve the sound quality, making the sound emitted from the speaker port 230 clear and loud, thus improving the user experience.

[0052] It can be seen that the tight fit between the door panel 300 and the rubber pad 200 not only forms a physical barrier, sealing the groove 280 and preventing the entry of external water droplets and dust, but also provides a relatively closed channel for sound propagation, reducing sound loss and interference during propagation and further improving the sound propagation effect.

[0053] In a further embodiment, the groove 280 includes a bottom wall 282 and side walls 283 disposed on both sides of the bottom wall 282, and the sound transmission hole 220 is formed on the bottom wall 282. The side walls 283 protrude from the opposite side 212 to form a surrounding structure. The side walls 283 prevent water droplets from entering the groove 280 through the opening 281. In this embodiment, an L-shaped surrounding structure of the side walls 283 is recommended, but this should not be construed as a limitation of the present invention. The L-shaped surrounding structure of the side walls 283 can effectively prevent water droplets or dust from entering the groove 280 from the opening 281. Its vertical portion can prevent water droplets or dust from directly entering the groove 280, while its horizontal portion can further prevent water droplets or dust from flowing into the groove 280 along the surface of the door panel 300, thereby providing more reliable waterproof protection for the lock 10.

[0054] In another embodiment, a channel (not shown) is formed inside the rubber pad 200, extending along the extension path of the sound channel 240, thus constituting the sound channel 240. Because the channel is formed inside the rubber pad 200, only the sound outlet 230 is exposed to the outside, allowing water droplets or dust to enter the channel only through the sound outlet 230. Furthermore, the internal structure of the sound channel 240 prevents water droplets or dust from flowing back into the housing 100. The design of the channel completely houses the sound channel 240 inside the rubber pad 200, with only the sound outlet 230 communicating with the outside, which greatly restricts the path of water droplets or dust into the lock 10. Even if a small amount of water droplets or dust enters the sound outlet 230, they are confined within the channel and cannot easily flow back into the housing 100, effectively protecting the speakers and other electronic components inside the housing 100.

[0055] Furthermore, because the channel is formed inside the rubber pad 200, the sound emitted by the speaker, after entering the channel through the sound guide hole 120 and the sound transmission hole 220, can only be emitted outward along the channel. This concentrates the sound, improving sound quality and making the sound emitted from the speaker outlet 230 clearer and louder, thus enhancing the user experience. The channel effectively guides and concentrates the sound, reducing scattering and attenuation during sound propagation, allowing the sound to be emitted more clearly and loudly from the speaker outlet 230, thereby improving the user experience.

[0056] In one embodiment, combined Figure 3 and Figure 4The base plate 110 is provided with a plurality of sound-guiding holes 120, and the rubber pad 200 is provided with a plurality of sound-transmitting holes 220. The plurality of sound-guiding holes 120 and the plurality of sound-transmitting holes 220 are correspondingly arranged. By providing a plurality of sound-guiding holes 120 and a plurality of sound-transmitting holes 220, the sound transmission efficiency is improved. In this embodiment, the plurality of sound-transmitting holes 220 are all located at the bottom of the main body section 241 of the speaker channel 240.

[0057] In one embodiment, combined Figure 4 A waterproof membrane 290 is provided between the front of the rubber pad 200 and the base plate 110. Specifically, the waterproof membrane 290 is disposed between the sound inlet 120 and the sound transmission hole 220 to prevent water vapor, water droplets, or dust from entering the housing 100 through the sound inlet 120, thereby preventing water vapor, water droplets, or dust from corroding the speaker and other electronic components installed in the housing 100, protecting the speaker and other electronic components installed in the housing 100, and extending the service life of the lock 10.

[0058] In one embodiment, combined Figure 1 and Figure 4 The rubber pad 200 is made of soft rubber material. It makes close contact with the housing 100 and the door panel 300, preventing hard contact between them and protecting the lock 10. The rubber pad 200, made of this soft rubber material, has good elasticity and cushioning properties, effectively absorbing and dispersing the pressure between the housing 100 and the door panel 300. This not only avoids hard contact between the housing 100 and the door panel 300, reducing the possibility of wear and damage, but also improves the stability and reliability of the lock 10, further protecting its structure and function.

[0059] In summary, the lock of this utility model, by setting the sound transmission hole obliquely above the speaker opening, prevents external water droplets or dust from flowing back into the housing through the speaker channel, avoids water droplets or dust from corroding the speaker and other electronic components installed in the housing, protects the speaker and other electronic components installed in the housing, extends the service life of the lock, and improves the sound transmission efficiency of the speaker through the speaker channel.
