Technical Field

[0001] This application relates to the field of locking device technology, and in particular to a door lock and a door. Background Technology

[0002] Door locks are becoming increasingly intelligent. Currently, smart door locks are generally equipped with sound-emitting components that can emit prompts or warning sounds when users input keys or other information. However, some door locks with sound-emitting components suffer from poor sound output when the sound outlet is located on a narrow surface of the door. Improving the sound output is a technical problem that requires solutions from those skilled in the art. Utility Model Content

[0003] To solve the above-mentioned technical problems, this application provides a door lock, which includes a housing and a sound-generating component and a circuit board located inside the housing. The sound-generating component is electrically connected to the circuit board. The housing includes a side wall and a bottom wall connected to the side wall. The housing has a sound cavity corresponding to the sound-generating component. The sound cavity has a first sound transmission channel and a second sound transmission channel. The first sound transmission channel and the second sound transmission channel have different sound transmission directions. The housing has a sound outlet, and the sound cavity is connected to the sound outlet.

[0004] In one embodiment of the door lock, a partition corresponding to the sound-emitting component is provided inside the acoustic cavity, and the first sound transmission channel is disposed on the partition. The partition divides the acoustic cavity into a first acoustic cavity and a second acoustic cavity, and the acoustic cavity is connected to the sound-emitting part through the second sound transmission channel.

[0005] In one embodiment of the door lock, one of the first acoustic cavity and the second acoustic cavity corresponds to the second sound transmission channel; or,

[0006] The second sound transmission channel includes a first sub-channel and a second sub-channel. The first acoustic cavity and the second acoustic cavity are respectively connected to the first sub-channel and the second sub-channel, and the first sub-channel and the second sub-channel are connected to the sound output section.

[0007] In one embodiment of the door lock, a protrusion is provided at one end of the partition near the bottom wall, and the second sound transmission channel corresponding to the first acoustic cavity is disposed on the protrusion.

[0008] In one embodiment of the door lock, the door lock includes a sealing element that presses against the side wall and the partition. The sealing element, the side wall, and the partition together form a second acoustic cavity. The sound outlet includes a bottom sound outlet disposed on the bottom wall. The second acoustic cavity has a corresponding second sound transmission channel, and the second acoustic cavity communicates with the bottom sound outlet through the corresponding second sound transmission channel.

[0009] In one embodiment of the door lock, the sealing element has a break on the side near the bottom wall, and the break forms a second sound transmission channel corresponding to the second acoustic cavity.

[0010] In one embodiment of the door lock, the sound-emitting part includes a side sound-emitting part disposed on the side wall and a bottom sound-emitting part disposed on the bottom wall, wherein a first sound transmission channel is connected to the side sound-emitting part and a second sound transmission channel is connected to the bottom sound-emitting part.

[0011] In one embodiment of the door lock, the sound-emitting part includes a bottom sound-emitting part disposed on the bottom wall, the bottom wall having a notch forming the bottom sound-emitting part; or, the sound-emitting part includes a side sound-emitting part disposed on the side wall, the side sound-emitting part including a sound-emitting hole disposed on the side wall.

[0012] In one embodiment of the door lock, the sound-emitting surface of the sound-emitting component is disposed facing the side wall, the first sound transmission channel extends in a direction perpendicular to the side wall, and the sound-emitting surface of the sound-emitting component and the orthographic projection of the first sound transmission channel on the side wall at least partially coincide.

[0013] This application also provides a door, the door including a door panel and a door lock as described in any of the above claims, the door panel having a door lock mounting position, and the door lock being mounted in the door lock mounting position.

[0014] In this door lock application, since the sound cavity corresponding to the sound-emitting component has a first sound transmission channel and a second sound transmission channel with different sound transmission directions, when the sound-emitting part is set on the narrow wall surface of the door lock, the sound-emitting surface of the sound-emitting component does not have to face the narrow wall surface where the sound-emitting part is located, but can face the wide wall surface of the door lock. When facing the wide wall surface of the door lock, the sound emitted by the sound-emitting component can still be transmitted to the sound-emitting part on the narrow wall surface of the door lock through the first and second sound transmission channels with different sound transmission directions. In this way, even if the sound-emitting part is set on the narrow wall surface of the door lock, it will not limit the sound-emitting surface area of ​​the sound-emitting component, thus achieving a better sound output effect.

[0015] The door provided in this application, because it includes the aforementioned door lock, also has the aforementioned technical effects. Attached Figure Description

[0034] To enable those skilled in the art to better understand the technical solution of this application, the following description is provided in conjunction with the appendix. Figure 1-7 The technical solutions of this application will be further described in detail below with reference to specific embodiments.

[0035] like Figure 1 and Figure 2 As shown, the door lock provided in this application includes a housing 1, a sound-generating component 3, and a circuit board 6. The sound-generating component 3 and the circuit board 6 are located inside the housing 1, and the sound-generating circuit of the sound-generating component 3 is integrated on the circuit board 6.

[0036] This application does not limit the type of the sound-generating component 3, such as it can be an electric sound-generating component, an electronic sound-generating component, a pneumatic sound-generating component, a vibration sound-generating component, etc. This application also does not limit the shape of the sound-generating component, such as it can be round, square, etc. Specifically, the sound-generating component 3 itself can have a shell, or it can be assembled directly inside the outer shell 1 without a shell.

[0037] The outer shell 1 can be a structure assembled from several parts. For example, in the illustrated embodiment, the outer shell 1 has a first shell portion 11 and a second shell portion 12, with the opening sides of the first shell portion 11 and the second shell portion 12 facing each other, together forming the inner cavity of the outer shell 1. Alternatively, the outer shell 1 can also be a one-piece structure.

[0038] The outer casing 1 includes a side wall 1a and a bottom wall 1b connected to the side wall 1a. In the installed state, the side wall 1a faces the door panel, and the bottom wall 1b faces the ground. In the illustrated embodiment, as shown... Figure 2 As shown, the sidewall of the outer casing 1 has a split structure, including an upper sidewall portion X1 and a lower sidewall portion X2, as follows. Figure 6 As shown, the sidewall of the outer shell 1 has an inner and outer layer structure, including an inner wall portion X3 and an outer wall portion X4. Alternatively, the sidewall of the outer shell 1 can also be a single-layer structure.

[0039] The outer casing 1 is provided with a sound cavity corresponding to the sound-generating component 3. For example, in the illustrated embodiment, such as... Figure 2 As shown, a cylinder 4 is provided facing the sound-emitting surface of the sound-emitting component 3, and the internal space of the cylinder 4 becomes part of the sound cavity. After assembly, the sound-emitting component 3 can be located entirely inside the sound cavity, or it can be located outside the sound cavity with the sound-emitting surface facing the sound cavity.

[0040] The acoustic cavity has a first sound transmission channel B and a second sound transmission channel C, and the sound transmission directions of the first sound transmission channel B and the second sound transmission channel C are different. For example, in the illustrated embodiment, the sound transmission direction of the first sound transmission channel B is approximately perpendicular to the side wall 1a, the first sub-channel C1 of the second sound transmission channel C has a certain angle with the side wall 1a, and the second sub-channel C2 of the second sound transmission channel C is approximately parallel to the side wall 1a or approximately perpendicular to the bottom wall 1b.

[0041] The outer casing 1 is provided with a sound outlet, and the sound cavity is connected to the sound outlet. For example, in the illustrated embodiment, the sound cavity is connected to the sound outlet through a second sound transmission channel C. The sound outlet is connected to the outside of the door lock.

[0042] Traditional door locks only have a sound transmission channel with a single sound transmission direction. When the sound output part is set on the narrow wall of the door lock, the sound-emitting surface of the sound-emitting component must be set towards the narrow wall where the sound output part is located. This results in the sound-emitting surface area of ​​the sound-emitting component needing to be made very small, thus causing poor sound output.

[0043] The door lock provided in this application has a first sound transmission channel B and a second sound transmission channel C corresponding to the acoustic cavity of the sound-emitting component 3. The sound transmission directions of the first sound transmission channel B and the second sound transmission channel C are different. Therefore, when the sound-emitting part is set on the narrow wall surface of the door lock, the sound-emitting surface of the sound-emitting component 3 does not have to be set towards the narrow wall surface where the sound-emitting part is located. Instead, it can be set towards the wide wall surface of the door lock. When it is set towards the wide wall surface of the door lock, the sound emitted by the sound-emitting component 3 can still be transmitted to the sound-emitting part on the narrow wall surface of the door lock through the first sound transmission channel B and the second sound transmission channel C with different sound transmission directions. In this way, even if the sound-emitting part is set on the narrow wall surface of the door lock, the sound-emitting surface area of ​​the sound-emitting component 3 will not be restricted. Therefore, a better sound output effect can be achieved.

[0044] For example, in the illustrated embodiment, the sound-emitting surface of the sound-emitting component 3 is disposed facing the wide side wall 1a, and the narrow bottom wall 1b is provided with a bottom sound outlet D. The sound emitted by the sound-emitting component 3 can be transmitted to the bottom sound outlet D through the first sound transmission channel B and the second sound transmission channel C in a zigzag manner.

[0045] In the illustrated embodiment, as Figure 1 and Figure 2 As shown, a partition 5 corresponding to the sound-emitting component 3 is provided inside the acoustic cavity. A first sound transmission channel B is disposed on the partition 5, which divides the acoustic cavity into a first acoustic cavity A1 and a second acoustic cavity A2. The acoustic cavity is connected to the sound-emitting part through the second sound transmission channel C. Specifically, in the figure, the first acoustic cavity A1 is closer to the sound-emitting component 3 than the second acoustic cavity A2. Figure 4 As shown, several circular holes on the partition 5 form the first sound transmission channel B.

[0046] More specifically, in the illustrated embodiment, the cylinder 4 encloses and forms the first acoustic cavity A1. The door lock includes a sealing element 2, which presses against the side wall 1a and the partition 5. The sealing element 2, the side wall 1a, and the partition 5 together enclose and form the second acoustic cavity A2. The second acoustic cavity A2 formed in this way has better sealing performance, which is more conducive to concentrating the sound and thus improving the sound output effect. Of course, the formation of the second acoustic cavity A2 is not limited to this; for example, it can also be formed by enclosing it with a cylinder, just like the first acoustic cavity A1.

[0047] In the illustrated embodiment, as Figures 3-7As shown, the second sound transmission channel C includes a first sub-channel C1 and a second sub-channel C2. The first acoustic cavity A1 is connected to the first sub-channel C1, and the second acoustic cavity A2 is connected to the second sub-channel C2. The first sub-channel C1 and the second sub-channel C2 are connected to the sound output section. Thus, the sound emitted by the sound-generating component 3 is transmitted sequentially through the first acoustic cavity A1 and the first sub-channel C1 to the sound output section, and sequentially through the first acoustic cavity A1, the first sound transmission channel C1, and the second sub-channel C2 to the sound output section. Both paths ultimately exit from the sound output section, resulting in a greater amount of sound reaching the sound output section, thus improving the sound output effect. Alternatively, either the first acoustic cavity A1 or the second acoustic cavity A2 may correspond to the second sound transmission channel C; that is, the first acoustic cavity A1 may correspond to the second sound transmission channel C, or the second acoustic cavity A2 may correspond to the second sound transmission channel C.

[0048] More specifically, in the illustrated embodiments, such as Figure 5 As shown, the seal 2 has a break 2a on the side near the bottom wall 1b, forming the aforementioned second sub-channel C2. By using the break 2a to form the second sub-channel C2, the break 2a is less likely to close when the seal 2 is compressed and deformed, thus ensuring the unobstructed flow of the second sub-channel C2. Alternatively, the second sub-channel C2 can also be formed by providing a through hole in a continuous seal. Figure 5 In the middle, the seal 2 is roughly U-shaped, but it is not limited to U-shape. For example, it can also be a circular seal with a break, a rectangular seal, etc.

[0049] More specifically, such as Figure 5 As shown, a protrusion Y is provided at one end of the partition 5 near the bottom wall 1b, and the second sound transmission channel C (i.e. the first sub-channel C1 in the figure) corresponding to the first acoustic cavity A1 is provided on the protrusion Y.

[0050] In the illustrated embodiment, the sound-emitting part includes a bottom sound-emitting part D disposed on the bottom wall 1b, and a second sound transmission channel C communicating with the bottom sound-emitting part D. Furthermore, the sound-emitting part may also include a side sound-emitting part disposed on the side wall 1a, and a first sound transmission channel B communicating with the side sound-emitting part. This allows sound to be emitted from both the bottom and the side, providing multi-directional sound output and improving the sound quality. Additionally, placing the sound-emitting part on the side and bottom walls makes it relatively inconspicuous.

[0051] Specifically, in the illustrated embodiment, a notch is provided on the bottom wall 1b, forming the aforementioned bottom sound outlet portion D. Specifically, the notch is formed by a partial indentation on the edge of the bottom wall 1b near the side wall 1a, moving away from the side wall 1a. Alternatively, the aforementioned bottom sound outlet portion D can also be formed by providing a through hole on the bottom wall 1b.

[0052] Specifically, the aforementioned side sound outlet may include a sound outlet hole disposed on the side wall 1a.

[0053] In some embodiments, such as Figure 6 or Figure 7 As shown, the orthographic projection of the sound-generating component 3 on the bottom shell wall 1a at least partially coincides with the first sound transmission channel B. This results in a shorter transmission distance between the sound-generating component 3 and the first sound transmission channel B, which is more conducive to improving the sound output effect.

[0054] This application also provides a door, the door including a door panel and the aforementioned door lock, the door panel having a door lock mounting position, and the door lock being mounted in the door lock mounting position.

[0055] The above embodiments can be freely combined without conflict.

[0056] The above examples illustrate the principles and implementation methods of this application. The descriptions of the embodiments are merely for the purpose of helping to understand the method and core ideas of this application. It should be noted that those skilled in the art can make various improvements and modifications to this application without departing from its principles, and these improvements and modifications also fall within the protection scope of this application.
