Description

Technical Field

[0001] This application belongs to the field of wall-mounted equipment technology, specifically relating to a wall-mounted device. Background Technology

[0002] Wall-mounted devices are those that are hung on walls, desktops, or brackets, and can include identity recognition devices, intercom devices, etc. Current wall-mounted devices consist of a device body and a mounting plate. The mounting plate has a vertically extending sliding track, and the device body has a sliding part that mates with the sliding track. When installing the device body, the sliding part on the device body needs to be inserted vertically into the sliding track on the mounting plate, and then the device body is fixed to the mounting plate. Since the device body and the mounting plate slide relative to each other, a certain amount of sliding space needs to be reserved above or below the mounting plate. Therefore, current wall-mounted devices require a relatively large vertical installation space to be installed. Summary of the Invention

[0003] The purpose of this application is to provide a wall-mounted device that can solve the problem that current wall-mounted devices require a large vertical installation space to be installed.

[0004] To solve the above-mentioned technical problems, this application is implemented as follows:

[0005] This application provides a wall-mounted device, including a device body, a mounting plate, a snap-fit ​​component, and a mating column. One of the device body and the mounting plate is provided with a snap-fit ​​component, and the other of the device body and the mounting plate is provided with a mating column.

[0006] The snap-fit ​​component includes multiple elastic claws spaced apart along a ring-shaped contour. The first end of each elastic claw is connected to one of the device body and the mounting plate. The first ends of each elastic claw together form an insertion port, and the second ends of each elastic claw together form a card interface. In the axial direction of the insertion port, the orthographic projection of the card interface is located within the orthographic projection of the insertion port.

[0007] The mating post can pass through the insertion port and be inserted into the card interface, and each elastic claw can be pressed. The second end of each elastic claw can be engaged with the mating post.

[0008] In this embodiment, the first end of each elastic claw forms an insertion port, and the second end of each elastic claw forms a card interface. In the axial direction of the insertion port, the orthographic projection of the card interface is located within the orthographic projection of the insertion port. That is, each elastic claw is inclined relative to the axis of the insertion port, and the second end of the elastic claw is closer to the axis of the insertion port than the first end of the elastic claw. The cross-sectional area of ​​the insertion port is larger than the cross-sectional area of ​​the card interface.

[0009] When the device body and the mounting plate are relatively close, the mating post can pass through the insertion port and insert into the card interface, pressing down on the second end of each elastic claw. That is, the insertion port and card interface are sequentially distributed in the insertion direction of the mating post. When the mating post has not passed through the insertion port, the cross-sectional area of ​​the mating post is smaller than the cross-sectional area of ​​the insertion port but larger than the cross-sectional area of ​​the card interface. Therefore, during the insertion process, the mating post presses down on the portion between the first and second ends of the elastic claws, causing the elastic claws to bend and deform, allowing the mating post to insert into the card interface, and thus enabling the second end of the elastic claws to engage with the mating post. Therefore, this application only requires the device body and the mounting plate to be relatively close to complete the installation of the device body, without needing to insert the device body vertically into the mounting plate. Thus, the wall-mounted device of this application requires less vertical installation space. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0023] The wall-mounted equipment provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0024] like Figures 1 to 11 As shown in the illustration, this application discloses a wall-mounted device, including a device body 100, a mounting plate 200, a snap-fit ​​component 300, and a mating post 400. One of the device body 100 and the mounting plate 200 is provided with the snap-fit ​​component 300, and the other of the device body 100 and the mounting plate 200 is provided with the mating post 400. Optionally, the wall-mounted device of this application can be an information recognition device, an intercom device, etc., wherein the information recognition device can be a smart access control system, a facial recognition device, a fingerprint recognition device, etc.; the mating post 400 can be a circular post or a square post.

[0025] The latching component 300 includes a plurality of elastic latches 310 spaced apart along an annular contour. The first end of each elastic latch 310 is connected to one of the device body 100 and the mounting plate 200. The first ends of each elastic latch 310 together form an insertion port 301, and the second ends of each elastic latch 310 together form a card interface 302. In the axial direction of the insertion port 301, the orthographic projection of the card interface 302 lies within the orthographic projection of the insertion port 301. That is, each elastic latch 310 is inclined relative to the axis of the insertion port 301, and the second end of each elastic latch 310 is closer to the axis of the insertion port 301 than the first end. The cross-sectional area of ​​the insertion port 301 is larger than the cross-sectional area of ​​the card interface 302. Optionally, the elastic latches 310 may be in the form of a sheet, column, etc.

[0026] The mating post 400 can pass through the insertion port 301 and be inserted into the card interface 302 and press each elastic claw 310. The second end of each elastic claw 310 can be engaged with the mating post 400. In this embodiment, when the device body 100 and the mounting plate 200 are relatively close, the mating post 400 can pass through the insertion port 301 and be inserted into the card interface 302, pressing the second end of each elastic claw 310. That is, the insertion port 301 and the card interface 302 are distributed sequentially in the insertion direction of the mating post 400, and the shape of the card interface 302 is adapted to the shape of the mating post 400. When the mating post 400 does not pass through the insertion port 301, the cross-sectional area of ​​the mating post 400 is smaller than the cross-sectional area of ​​the insertion port 301 and larger than the cross-sectional area of ​​the card interface 302. Therefore, during the insertion process of the mating post 400, the mating post 400 will press the part between the first end and the second end of the elastic claw 310, thereby causing the elastic claw 310 to bend and deform, so that the mating post 400 is inserted into the card interface 302, and then the second end of the elastic claw 310 is engaged with the mating post 400. Therefore, this application only requires bringing the device body 100 and the mounting plate 200 relatively close to each other to complete the installation of the device body 100, without needing to insert the device body 100 vertically into the mounting plate 200. Thus, the wall-mounted device of this application requires less vertical installation space. Furthermore, this application does not use screws to fix the device body 100 to the mounting plate 200, which reduces the assembly difficulty between the device body 100 and the mounting plate 200.

[0027] To facilitate disengagement of the elastic claws 310 from the mating posts 400, in an optional embodiment, please refer to... Figure 7 and Figure 9The wall-mounted device also includes an unlocking component 500, which can move relative to the mating post 400. When the unlocking component 500 moves relative to the mating post 400, it can press down on each elastic claw 310, causing the second end of each elastic claw 310 to disengage from the mating post 400. The specific operation is as follows: after the elastic claw 310 engages with the mating post 400, the unlocking component 500 is moved relative to the mating post 400 to approach and press down on each elastic claw 310. At this time, each elastic claw 310 will bend and deform, thereby increasing the cross-sectional area of ​​the locking interface 302, and thus disengaging the second end of the elastic claw 310 from the mating post 400. Therefore, this embodiment only requires controlling the movement of the unlocking component 500 relative to the mating post 400 to disengage the elastic claw 310 from the mating post 400, making the operation relatively simple.

[0028] To prevent the unlocking member 500 from moving excessively and damaging the elastic pawl 310. In an optional embodiment, please refer to... Figure 5 The unlocking component 500 is slidably sleeved on the outside of the mating post 400. The outer surface of the mating post 400 has a limiting surface 401. The unlocking component 500 and the limiting surface 401 engage in a limiting engagement in a first direction. When the unlocking component 500 presses down on each elastic claw 310, the limiting surface 401 stops and limits the unlocking component 500. The first direction is the direction from one end of the mating post 400 connected to the other of the equipment body 100 and the hanging plate 200 to the other end of the mating post 400. Here, one end and the other end of the mating post 400 are the two opposite ends of the mating post 400. Optionally, a limiting structure with the limiting surface 401 can be additionally provided on the mating post 400, or an annular groove can be provided on the outer circumferential surface of the mating post 400. The annular groove extends to the end face of the end of the mating post 400 connected to the other of the equipment body 100 and the hanging plate 200. In this case, the limiting surface 401 is the bottom wall of the annular groove.

[0029] In this embodiment, the unlocking member 500 is slidably sleeved on the outside of the mating post 400. During its movement in the first direction, the unlocking member 500 can press each elastic claw 310. When each elastic claw 310 disengages from the mating post 400, the limiting surface 401 can limit the unlocking member 500 in the first direction. That is, after the unlocking member 500 moves along the first direction to disengage the second ends of each elastic claw 310 from the mating post 400, the limiting surface 401 can stop the unlocking member 500, thereby preventing it from continuing to move in the first direction and preventing excessive pressure on the elastic claws 310, which could damage them. Furthermore, the limiting surface 401 also prevents the unlocking member 500 from detaching from the mating post 400. Of course, the unlocking component 500 may not be sleeved on the outside of the mating post 400. In this case, the unlocking component 400 may be slidably disposed on one of the equipment body 100 and the hanging plate 200. For example, when one of the equipment body 100 and the hanging plate 200 is provided with a recess 120, the unlocking component 400 may be slidably disposed in the recess 120.

[0030] In one alternative embodiment, please refer to Figure 9 and Figure 10The wall-mounted device also includes an unlocking pusher 600. When the second end of each elastic claw 310 is engaged with the mating post 400, that is, when the device body 100 is assembled to the mounting plate 200, there is an insertion channel 110 between the device body 100 and the mounting plate 200. A part of the unlocking member 500 is disposed opposite to the insertion channel 110. The unlocking pusher 600 can contact the unlocking member 500 through the insertion channel 110 to push the unlocking member 500 to move in the direction close to the elastic claw 310. In this embodiment, with the second end of each elastic claw 310 engaged with the mating post 400, an insertion channel 110 exists between the device body 100 and the mounting plate 200. A portion of the unlocking member 500 is positioned opposite the insertion channel 110. That is, when the unlocking member 500 is stationary, a portion of it faces the insertion channel 110. Therefore, the unlocking pusher 600, inserted through the insertion channel 110, contacts the unlocking member 500, thereby pushing it to move and disengaging the elastic claws 310 from the mating post 400. It is evident that this embodiment uses the unlocking pusher 600 to drive the unlocking member 500. Since the unlocking pusher 600 is a sheet-like structure, the width of the insertion channel 110 between the device body 100 and the unlocking member 500 is relatively small. In other words, the installation space occupied between the device body 100 and the mounting plate 200 using this embodiment is smaller, thus reducing the thickness of the wall-mounted device. Of course, a drive device can also be installed on the equipment body 100 or the mounting plate 200 to drive the unlocking component 500 to move. The drive device can be an electric cylinder, a motor-driven lead screw and nut mechanism, a motor-driven linkage mechanism, etc.

[0031] In one optional embodiment, the unlocking member 500 includes a disc body 510 and an unlocking sleeve 520. The disc body 510 has a first disc surface and a second disc surface disposed opposite to each other. The unlocking sleeve 520 is connected to the first disc surface, and the second disc surface has a guide surface 511. When the second ends of each elastic claw 310 are engaged with the mating post 400, the guide surface 511 has a gap 201 communicating with the insertion channel 110 between it and the other of the device body 100 and the hanging plate 200. In a second direction, the width of the gap 201 gradually increases, and the unlocking pusher 600 can pass through at least a portion of the insertion channel 110 and the gap 201 in sequence and contact the second disc surface. The second direction is the direction extending from the central region of the disc body 510 to the edge region of the disc body 510. In this embodiment, the second disc faces the other of the device body 100 and the mounting plate 200. The guide surface 511 of the second disc has a gap 201 communicating with the insertion channel 110 between it and the other of the device body 100 and the mounting plate 200. The width of the gap 201 gradually increases in the second direction. That is, in the insertion direction of the unlocking pusher 600, the width of the portion of the gap 201 facing the insertion channel 110 gradually decreases. Specifically, the width of the portion of the gap 201 near the insertion channel 110 is larger, and the width of the portion of the gap 201 away from the insertion channel 110 is smaller. This allows the unlocking pusher 600 to more easily enter the gap 201 after passing through the insertion channel 110. Furthermore, as the unlocking pusher 600 is inserted, the width of the gap 201 decreases, thus providing guidance for the unlocking pusher 600 to contact the second disc. Optionally, the guide surface 511 can be an inclined surface, an arc surface, a frustum-shaped surface, etc.

[0032] Optionally, after the unlocking pusher 600 contacts the unlocking member 500, the unlocking pusher 600 can rotate around a fulcrum, leveraging the unlocking member 500 to move it. However, this requires the insertion channel 110 and the gap 201 to have a large width, which would increase the thickness of the wall-mounted device. In an optional embodiment, the unlocking pusher 600 has an unlocking end with a first plate surface and a second plate surface arranged opposite to each other. The second plate surface has a wedge-shaped surface 610 that can contact the unlocking member 500, and the distance between the wedge-shaped surface 610 and the first plate surface gradually decreases in the insertion direction of the unlocking pusher 600. In this embodiment, the unlocking end has a first plate surface and a second plate surface arranged opposite to each other. The second plate surface has a wedge-shaped surface 610. The distance between the wedge-shaped surface 610 and the first plate surface gradually decreases in the insertion direction of the unlocking pusher 600. That is, the thickness of the part of the unlocking end with the wedge-shaped surface 610 gradually decreases in this insertion direction. During the insertion of the unlocking pusher 600, the part of the unlocking end with the thinnest wedge-shaped surface 610 will enter the insertion channel 110 first. This makes it easier for the unlocking end to enter the insertion channel 110. As the unlocking pusher 600 continues to be inserted, the wedge-shaped surface 610 contacts the unlocking member 500, and the unlocking member 500 can be moved by the wedge-shaped surface 610. It can be seen that after providing the wedge-shaped surface 610 on the unlocking pusher 600 in this embodiment, the unlocking member 500 can be moved during the insertion of the unlocking pusher 600 without the unlocking pusher 600 rotating around the fulcrum. This reduces the thickness of the wall-mounted device. Optionally, the end of the unlocking pusher 600 furthest from the unlocking end is a bent end 630, which makes it easier for the user to operate.

[0033] And / or, in an optional embodiment, the unlocking pusher 600 has an unlocking end with a first notch 620 at its edge. When the unlocking member 500 moves relative to the mating post 400, a portion of the mating post 400 is located within the first notch 620. If the unlocking end does not have a first notch 620 at its edge, the unlocking end may touch the mating post 400 during the insertion of the unlocking pusher 600. In this case, the mating post 400 will block the unlocking end from further penetration, which may reduce the stroke of the unlocking pusher 600 pushing the unlocking member 500. However, in this embodiment, the unlocking end has a first notch 620 at its edge. When the unlocking member 500 moves relative to the mating post 400, a portion of the mating post 400 is located within the first notch 620. This avoids the mating post 400 blocking the unlocking end from further penetration, thereby increasing the stroke of the unlocking pusher 600 pushing the unlocking member 500.

[0034] Furthermore, the width of the first notch 620 gradually increases in the insertion direction of the unlocking pusher 600. In this embodiment, during the insertion of the unlocking pusher 600, the mating post 400 will enter the first notch 620 through the wider portion of the first notch 620, thus facilitating the entry of the mating post 400 into the first notch 620.

[0035] In one optional embodiment, a recess 120 is provided on one of the device body 100 and the mounting plate 200, and the snap-fit ​​member 300 is disposed within the recess 120. In this embodiment, the snap-fit ​​member 300 is disposed within the recess 120. Compared to the snap-fit ​​member 300 protruding from either the device body 100 or the mounting plate 200, this embodiment can save the installation space occupied by the snap-fit ​​member 300 outside of either the device body 100 or the mounting plate 200, thereby reducing the thickness of the wall-mounted device.

[0036] Further, please refer to Figure 2 The snap-fit ​​component 300 also includes a base portion 320, which extends circumferentially along the recess 120. The first end of each elastic claw 310 is connected to the base portion 320. The inner peripheral wall of the recess 120 is provided with a mounting groove 121, and at least a portion of the base portion 320 is disposed in the mounting groove 121. Optionally, the base portion 320 may be annular, arc-shaped, or the like. When the snap-fit ​​component 300 only includes elastic claws 310, the end of the elastic claw 310 can be connected to either the equipment body 100 or the mounting plate 200. However, the area of ​​the end of the elastic claw 310 is small; that is, the connection area between the snap-fit ​​component 300 and either the equipment body 100 or the mounting plate 200 is small, resulting in lower connection strength. In this embodiment, the snap-fit ​​component 300 includes a base portion 320 connected to the elastic claw 310. The base portion 320 is disposed in the mounting groove 121 on the inner peripheral wall of the recess 120, so that the front, back and outer peripheral surfaces of the base portion 320 can fit against the three inner walls of the mounting groove 121 respectively, thereby increasing the connection area and connection strength of one of the equipment body 100 and the hanging plate 200.

[0037] In one optional embodiment, the edge of the base portion 320 is provided with a plurality of second notches 321 spaced apart, and the plurality of second notches 321 are distributed circumferentially around the base portion 320. In this embodiment, the presence of a plurality of second notches 321 on the edge of the base portion 320 improves the deformability of the base portion 320, thereby facilitating the assembly of the base portion 320 into the mounting groove 121. Furthermore, after the base portion 320 is assembled into the mounting groove 121, adhesive can be applied to the mounting groove 121 to fix the base portion 320 to the mounting groove 121. In this case, providing second notches 321 on the base portion 320 increases the adhesive application area, thereby increasing the connection strength between the base portion 320 and the mounting groove 121.

[0038] Optionally, please refer to Figure 3The recessed portion 120 includes a first hole segment 122 and a second hole segment 123 distributed sequentially along a first direction. The cross-sectional area of ​​the first hole segment 122 is larger than that of the second hole segment 123. The elastic claw 310 is located within the second hole segment 123. When the device body 100 is connected to the hanging plate 200, the disc 510 of the unlocking member 500 is located within the first hole segment 122. Furthermore, the bottom wall of the first hole segment 122 is provided with an annular protrusion 130. The cross-sectional area of ​​the inner hole of the protrusion 130 gradually decreases in the first direction. The mounting groove 121 is provided on the inner circumferential surface of the protrusion 130, which facilitates the installation of the base portion 320 into the mounting groove 121.

[0039] In one alternative embodiment, please refer to Figure 2 At least one second notch 321 is opposite to one of the elastic claws 310, and the second notch 321 extends toward the first end of the elastic claw 310. In this embodiment, the second notch 321 is opposite to the corresponding elastic claw 310 and extends toward the first end of the elastic claw 310, which can release the stress on the part of the base portion 320 opposite to the elastic claw 310, thereby making the elastic claw 310 easier to deform.

[0040] When installing wall-mounted devices, a mounting groove with a depth matching the thickness of the device is typically created on the mounting surface. A mounting plate 200 is then placed on the bottom wall of the mounting groove, and the device body 100 is placed on the mounting plate 200, positioning the device body 100 in a preset position. At this point, the device body 100 is flush with the mounting surface or slightly protrudes from it. If the groove depth is too large, the device body 100 will not be in the preset position; that is, the device body 100 will be completely within the mounting groove and lower than the mounting surface.

[0041] In an optional embodiment, the mating post 400 includes a snap-fit ​​post 410 and a mounting post 420. The mounting post 420 is located on the other of the equipment body 100 and the mounting plate 200. The snap-fit ​​post 410 can press the second end of each elastic claw 310, and the second end of each elastic claw 310 can engage with the snap-fit ​​post 410. The snap-fit ​​post 410 can be telescopically sleeved on the outside of the mounting post 420 to adjust the distance between the snap-fit ​​post 410 and the other of the equipment body 100 and the mounting plate 200. Optionally, the snap-fit ​​post 410 and the mounting post 420 can be connected by threads. In this embodiment, the mounting post 420 is located on the other of the device body 100 and the hanging plate 200. The snap-fit ​​post 410 is telescopically sleeved on the outside of the mounting post 420. By controlling the telescopic movement of the snap-fit ​​post 410 on the mounting post 420, the distance between the snap-fit ​​post 410 and the other of the device body 100 and the hanging plate 200 can be controlled. This controls the distance between the device body 100 and the hanging plate 200 when the elastic claw 310 is engaged with the snap-fit ​​post 410, thereby allowing the wall-mounted device to adapt to mounting grooves 121 of different depths.

[0042] In one optional embodiment, the second end of each elastic claw 310 can engage with the outer peripheral surface of the mating post 400, and the portion of the mating post 400 in contact with each elastic claw 310 is deformable. This embodiment utilizes the deformable characteristic of the portion of the mating post 400 in contact with each elastic claw 310 to allow the outer peripheral surface of the mating post 400 itself to engage with the elastic claw 310, thus eliminating the need for additional engagement structures and simplifying the structure of the mating post 400 and the elastic claw 310. It should be noted that the mating post 400 can also be a rigid structural component. In this case, a first engagement portion can be provided on the elastic claw 310, and a second engagement portion can be provided on the mating post 400, with the first engagement portion engaging with the second engagement portion.

[0043] Optionally, the snap-fit ​​post 410 includes an outer post 411 and an inner post 412. The inner post 412 is threadedly connected to the mounting post 420, and the outer post 411 is sleeved on the outside of the inner post 412. Thus, the outer post 411 and the inner post 412 can be made of different materials.
