Detailed Description

To make the objects, technical solutions and advantages of the present application more clear, the technical solutions of the present application will be clearly and completely described below with reference to specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without making any creative effort belong to the protection scope of the present application.

Technical solutions disclosed in the embodiments of the present application are described in detail below with reference to the accompanying drawings.

In order to solve the problems that the wall-mounted equipment in the related art is complex in installation process and easy to fall and damage, the embodiment of the application provides the wall-mounted equipment. In the embodiment of the present application, the wall-mounted device has multiple types, such as an intelligent door access, a building intercom, a doorbell, a flat-panel television, a projection screen, and the like, and the embodiment of the present application does not specifically limit the types.

As shown in fig. 1 to 9, the wall hanging apparatus disclosed in the embodiment of the present application includes a wall hanging machine 100, a wall hanging plate 200, and a limiting member 300.

As shown in fig. 1 and 2, the wall-hanging machine 100 is a main body of the wall-hanging device, and the installation of the wall-hanging device mainly refers to the installation of the wall-hanging machine 100. The wall hanging plate 200 is an auxiliary mounting member of the wall hanging device, and can be mounted on the mounting base 400 and serves as an adapter of the wall hanging whole machine 100 to mount the wall hanging whole machine 100. The embodiment of the present application does not limit the specific type of the installation base 400, and it may be a wall surface, furniture, a wall-mounted bracket, and the like.

The wall-hanging complete machine 100 includes a cover body 110, and a plurality of through avoiding holes 111 are opened on the cover body 110, that is, the avoiding holes 111 can communicate the inner cavity of the wall-hanging complete machine 100 with the outside. The wall hanging plate 200 includes a plate body 210 and a plurality of clamping elements 220 having the same number as the avoiding holes 111, the plate body 210 can be installed on the installation base 400, and the avoiding holes 111 are used for the clamping elements 220 to pass through. The board body 210 is a main body part of the wall hanging board 200, and the wall hanging board 200 is installed by connecting and matching the board body 210 and the installation foundation 400; specifically, the plate body 210 may be provided with a mounting hole 211, and the plate body 210 may be connected to the mounting base 400 by inserting a fastener into the mounting hole 211. In the embodiment of the present application, the engaging element 220 needs to extend into the wall-hanging machine 100 to achieve a matching relationship with the limiting member 300, which is described later, and specifically, can extend into the wall-hanging machine 100 through the avoiding hole 111.

In the embodiment of the present application, the cover body 110 is generally a rear cover, but it may be other housing portions such as a side cover. An avoidance area 212 is generally formed in the wall hanging plate 200, the avoidance area 212 is used for avoiding the interface assembly 120 passing through the wall hanging whole machine 100, and the interface assembly 120 can pass through the avoidance area 212 to be connected with a line interface in the installation base 400.

Meanwhile, as shown in fig. 6 to 9, the clip element 220 of the embodiment of the present application includes a connecting portion 221 and a limiting portion 222, the connecting portion 221 connects the plate body 210 and the limiting portion 222, and at least a portion of the limiting portion 222 protrudes relative to the connecting portion 221 in the circumferential direction of the clip element 220; the limiting member 300 is an elastic structural member, the limiting member 300 is installed on the cover body 110 and located on a moving path of the limiting portion 222, and the limiting member 300 is configured to deform to avoid the limiting portion 222 when the clamping element 220 extends into the avoiding hole 111, so that the limiting portion 222 extends into the wall-hanging whole machine 100 and is in limiting fit with the limiting member 300.

It should be understood that, with this configuration, since the avoiding hole 111 is a through hole, when the clamping element 220 passes through the avoiding hole 111 and extends into the wall-hanging machine 100, the wall-hanging plate 200 can support the cover body 110 of the wall-hanging machine 100 through the clamping element 220, thereby implementing the installation of the wall-hanging machine 100. Therefore, after the wall hanging plate 200 is mounted on the mounting base 400, the wall hanging complete machine 100 can be assembled by pushing the wall hanging complete machine in the forward direction, so that the alignment of the clamping element 220 and the avoiding hole 111 can be realized only by adjusting the relative position of the cover body 110 and the wall hanging plate 200 in the vertical plane; in a reverse view of the hanging type assembly method in the related art, the wall hanging complete machine 100 needs to be moved upwards, then the wall hanging hole of the cover body 110 needs to be aligned with the bent hook on the wall hanging plate 200, but the alignment operation of the wall hanging hole and the hook needs to adjust the relative position of the cover body 110 and the wall hanging hole in the vertical plane and the horizontal plane, and the alignment difficulty is undoubtedly greater; compared with the prior art, the wall-mounted equipment is smaller in assembling difficulty, and further the technical effect of simplifying the installation process can be achieved.

In the embodiment of the present application, in the circumferential direction of the clamping element 220, a part of the position-limiting portion 222 may be protruded relative to the connecting portion 221, or all of the position-limiting portions 222 may be protruded relative to the connecting portion 221. With such an arrangement, the limiting portion 222 correspondingly increases the circumferential dimension of a partial region of the clamping element 220, and when the clamping element 220 extends into the avoiding hole 111, the limiting member 300 is located on the moving path of the limiting portion 222, so that the limiting member 300 interferes with the limiting portion 222.

Because the limiting member 300 is an elastic structural member, based on its own elastic characteristic, in the process of assembling the wall-hanging complete machine 100, the clamping element 220 extends into the avoiding hole 111 to cause interference between the limiting member 300 and the limiting portion 222, and if the wall-hanging complete machine 100 is pushed, the limiting member 300 will elastically deform to avoid the limiting portion 222, so that the limiting portion 222 can extend into the inner cavity of the wall-hanging complete machine 100 through the limiting member 300; after the position-limiting member 300 is staggered from the position-limiting portion 222, the position-limiting member 300 corresponds to the connecting portion 221, the connecting portion 221 does not press the position-limiting member 300 as the position-limiting portion 222, the deformation of the position-limiting member 300 disappears and returns to its original shape, and at this time, a mutual position-limiting fit relationship is formed between the position-limiting member 300 and the position-limiting member 300, so that the cover 110 is snap-fitted to the snap-fit element 220. In this case, if the wall-hanging complete machine 100 is to be detached from the wall-hanging plate 200 according to the embodiment of the present application, a certain degree of external driving action needs to be applied to detach the wall-hanging complete machine 100 from the wall-hanging plate 200, so that the wall-hanging complete machine 100 is ensured not to fall accidentally when being subjected to human touch, earthquake vibration, and the like, and the installation reliability of the whole wall-hanging device is optimized.

In the embodiment of the present application, the specific material of the limiting member 300 is not limited, and may be a metal material, a plastic material, a polymer material, etc., as long as the elastic deformation is realized and the damage is not easily caused.

As can be seen from the above description, in the wall hanging device disclosed in the embodiment of the present application, since the limiting member 300 is an elastic structural member and is configured to deform to avoid the limiting portion 222 when the clamping element 220 extends into the avoiding hole 111, so that the limiting portion 222 extends into the wall hanging whole machine 100 and then is clamped and matched with the limiting member 300, the structural layout is assembled by pushing the wall hanging whole machine 100 forward toward the wall hanging plate 200, and compared with the hooking type assembling manner in the related art, the clamping element 220 and the avoiding hole 111 in the embodiment of the present application are easily aligned with each other, thereby simplifying the installation process of the wall hanging device; meanwhile, after the limiting portion 222 of the embodiment of the present application extends into the wall-hanging machine 100, it will be limited and matched with the limiting member 300, so that the clamping element 220 is clamped and matched with the cover body 110, and thus, even if it is affected by human touch, earthquake vibration, etc., the wall-hanging machine 100 will not be separated from the wall-hanging plate 200, and the installation reliability of the wall-hanging equipment is further optimized.

In the embodiment of the present application, the specific configurations of the clamping element 220 and the limiting member 300 are not limited, for example, in the circumferential direction of the clamping element 220, the circumferential dimension of the limiting portion 222 is greater than the circumferential dimension of the connecting portion 221, and may specifically be a stepped pillar structure; accordingly, the limiting member 300 may be a ring-shaped structure. However, when the clamping element 220 and the limiting member 300 are engaged, the deformation margin of the limiting member 300 is small, and the abrasion between the limiting portion 222 and the limiting member 300 is serious.

In another embodiment, as shown in fig. 5 to 9, the limiting portion 222 of the embodiment of the present application may include two protrusions 222a protruding away from each other, that is, the protruding directions of the two protrusions 222a are opposite; the position limiter 300 includes two support arms 310 and a connecting section 320, the two support arms 310 are respectively connected to two ends of the connecting section 320, and the two support arms 310 are oppositely disposed; the limiting portion 222 is respectively matched with the two support arms 310 in a limiting manner through two protrusions 222 a.

It should be understood that the position limiter 300 of the present embodiment can have various shapes, for example, the two arms 310 and the connecting section 320 can be U-shaped or U-shaped; alternatively, the shape of the stopper 300 can be adjusted by changing the shape of the connecting segment 320, for example, the connecting segment 320 may have a V-shape.

Under the structure layout, when the clamping element 220 extends into the avoiding hole 111, the two support arms 310 interfere with the two protrusions 222a, the protrusions 222a can press the corresponding support arms 310 to deform the support arms 310, when the wall-hanging complete machine 100 is continuously pushed, the support arms 310 can be further deformed until the support arms 310 avoid the protrusions 222a, the protrusions 222a smoothly enter the inner cavity of the wall-hanging complete machine 100, at the moment, the two protrusions 222a are respectively in limit fit with the two support arms 310, and the clamping fit relationship between the cover body 110 and the clamping element 220 is further realized.

Compared with the ring-shaped limiting element 300, the ends of the two support arms 310 away from the connecting section 320 are both free ends, that is, the limiting element 300 of the embodiment of the present application is not in a closed-loop structure, and the two support arms 310 are not restricted by each other when being pressed by the protrusion 222a, so that the two support arms 310 have a larger deformation margin to reduce the wear between the limiting portion 222 and the limiting element 300. Meanwhile, the two support arms 310 are symmetrically arranged, so that the whole limiting member 300 is relatively balanced in extrusion action of the limiting part 222, the limiting member 300 is ensured not to generate unidirectional deformation after being used for a long time, and the service life can be prolonged.

In this embodiment, the limiting member 300 may be a metal wire, specifically, a steel wire.

As shown in fig. 8, the distance between the flanges of the two protrusions 222a is a, and the distance between the support arms 310 is b, where a is greater than b, so that when the latch member 220 extends into the avoiding hole 111, the protrusions 222a will necessarily interfere with each other by passing through the support arms 310, that is, the support arms 310 are disposed on the moving path of the protrusions 222 a; as also described above, when the latch member 220 passes through the position-limiting member 300, the protrusion 222a is in position-limiting engagement with the arm 310.

In order to improve the smoothness of the wall-hanging complete machine 100 during assembly and disassembly, as shown in fig. 7, the protrusion 222a of the embodiment of the present application may have a first guide surface 222a1 and a second guide surface 222a2, the first guide surface 222a1 is disposed on a side of the protrusion 222a away from the plate body 210, and the first guide surface 222a1 is used for guiding the protrusion 222a to pass through the support arm 310, so that the protrusion 222a extends into the wall-hanging complete machine 100 and is in limit fit with the support arm 310; the second guiding surface 222a2 is disposed on a side of the protrusion 222a facing the board body 210, and the second guiding surface 222a2 is used for guiding the protrusion 222a to pass through the supporting arm 310, so that the latch member 220 is moved out of the wall hanging whole machine 100.

Under the structure layout, no matter in the process of installing the wall-hanging complete machine 100 or in the process of disassembling the wall-hanging complete machine 100, when the support arm 310 interferes with the protrusion 222a, due to the existence of the first guide surface 222a1 and the second guide surface 222a2, the support arm 310 can deform more quickly along the extending direction of the guide surfaces, so that the efficiency of avoiding the support arm 310 passing through the protrusion 222a can be improved, the serious abrasion between the support arm 310 and the protrusion 222a is avoided, and the effect of improving the assembling and disassembling smoothness of the wall-hanging complete machine 100 is achieved.

In the embodiment of the present application, the specific configurations of the first guide surface 222a1 and the second guide surface 222a2 are not limited, and they may be, for example, a plane or an arc surface, or one of them may be a plane and the other may be an arc surface, as long as the guiding function can be achieved.

As shown in fig. 7, in an embodiment where the first guide surface 222a1 and the second guide surface 222a2 are both planar, an angle between the first guide surface 222a1 and the axial direction of the connection portion 221 is a first angle α, an angle between the second guide surface 222a2 and the axial direction of the connection portion 221 is a second angle β, and the first angle α may be smaller than the second angle β. Under such a configuration, the inclination degree of the first guiding surface 222a1 is smaller, so that the interference between the protrusion 222a and the support arm 310 is smaller, which is beneficial to realizing the quick installation of the wall-hanging whole machine 100; the inclination degree of the second guiding surface 222a2 is greater, so that the interference between the protrusion 222a and the supporting arm 310 is greater, the difficulty in detaching the wall-hanging whole machine 100 is increased, and the wall-hanging whole machine 100 and the wall-hanging plate 200 can be disengaged only by applying greater external driving work, so that the installation reliability of the wall-hanging device can be further optimized.

In an optional scheme, the edge corner of the first guide surface 222a1 in the embodiment of the present application may transition through an arc, so that the interference between the protrusion 222a and the support arm 310 can also be reduced, and the installation convenience of the wall-hanging complete machine 100 is further optimized.

In order to ensure accurate installation of the limiting member 300, so that the limiting portion 222 corresponds to the limiting member 300 accurately, as shown in fig. 3 to 5, the cover body 110 according to the embodiment of the present application may include a positioning assembly disposed on an inner wall thereof, the positioning assembly includes a first positioning member 112, a second positioning member 113 and a third positioning member 114, the first positioning member 112 is configured to be in positioning fit with the limiting member 300 in a first direction, the second positioning member 113 is configured to be in positioning fit with the limiting member 300 in a second direction, and the third positioning member 114 is configured to be in positioning fit with the limiting member 300 in a third direction; the first direction is perpendicular to the second direction, and the third direction is perpendicular to a plane where the first direction and the second direction are located.

Under the structural layout, the first direction, the second direction and the third direction are perpendicular to each other, and when the limiting member 300 is positioned and installed on the cover body 110 through the first positioning element 112, the second positioning element 113 and the third positioning element 114, the three-dimensional coordinates of the limiting member 300 are limited, so that the high-precision installation of the limiting member 300 is realized, the limiting member 300 can be accurately corresponded to the limiting portion 222, that is, the limiting member 300 is located on the moving path of the limiting portion 222.

It should be noted that the specific directions of the first direction, the second direction, and the third direction are not limited in the embodiments of the present application, and they may be any directions, and only the conditions that the first direction is perpendicular to the second direction and the third direction is perpendicular to the plane where the first direction and the second direction are located need to be satisfied. In order to facilitate the intuitive description of the directions of the first direction, the second direction and the third direction, as shown in fig. 5, in the spatial coordinate system constructed in the embodiment of the present application, the first direction may be located in an X-axis direction, the second direction may be located in a Y-axis direction, and the third direction may be located in a Z-axis direction. For the convenience of the text, the spatial coordinate system of the first direction, the second direction and the third direction components are used for the subsequent description.

Of course, the specific installation manner of the limiting member 300 on the cover body 110 is not limited in the embodiment of the present application, and in another embodiment, the limiting member 300 may be formed on the cover body 110 by injection molding; however, this mounting method is high in processing cost, and greatly restricts the deformation of the stopper 300, which is not favorable for the stopper 300 to escape through the stopper portion 222.

Specifically, as shown in fig. 5, the first positioning element 112 of the embodiment of the present application may include two first positioning stages 112a disposed in parallel and spaced apart, the two first positioning stages 112a are both arranged to extend along the second direction, and the connection segment 320 is configured to be installed between the two first positioning stages 112a in a positioning manner, so that the limiting element 300 is positioned in the first direction. Under such a configuration, since the two first positioning tables 112a are both disposed to extend along the second direction, that is, they are both disposed to extend along the Y-axis direction, and thus the arrangement direction of the two first positioning tables 112a is located on the X-axis direction, the connecting segment 320 of the position-limiting member 300 is positioned on the X-axis direction after being disposed between the two first positioning tables 112a, and further the X coordinate of the position-limiting member 300 is determined.

In another embodiment, one of the two first positioning platforms 112a is positioned and matched with the connecting end, the other one is positioned and matched with the free ends of the two support arms 310, and the limiting member 300 is positioned between the two first positioning platforms 112 a.

Specifically, as shown in fig. 5, the second positioning element 113 according to the embodiment of the present disclosure may include two second positioning stages 113a disposed in parallel and spaced apart, the two second positioning stages 113a are both disposed to extend along the first direction, and the two support arms 310 are configured to be respectively in positioning fit with the end surfaces of the two second positioning stages 113a on the opposite sides, so that the limiting element 300 is positioned in the second direction. With this arrangement, since the two second positioning stages 113a are both disposed to extend along the first direction, that is, they are both disposed to extend along the X-axis direction, and thus the arrangement direction of the two second positioning stages 113a is located along the Y-axis direction, when the two support arms 310 are disposed between the two second positioning stages 113a, the two second positioning stages 113a can position the two support arms 310 by their opposite side ends, and thus the Y-coordinate of the position-limiting member 300 is determined.

In other embodiments, the two arms 310 may also be configured to be positioned and engaged with the opposite side end surfaces of the two second positioning tables 113 a.

In order to facilitate the two arms 310 of the limiting member 300 to smoothly move between the two second positioning tables 113a, as shown in fig. 5, one end of the second positioning table 113a of the embodiment of the application may be provided with a guide portion 113a1, the guide portion 113a1 is disposed obliquely with the second positioning table 113a and is inclined toward a direction away from the other second positioning table 113a, and the guide portion 113a1 is used for guiding the arm 310 to slide to be in positioning fit with the second positioning table 113 a.

Under the structural layout, the two guide portions 113a1 are arranged obliquely back to back, so that the closer to the areas of the free ends of the two guide portions 113a1, the larger the opening distance between the two guide portions 113a1, therefore, when the pick-up limiting member 300 adjusts the free ends of the two support arms 310 to extend into the space between the two second positioning tables 113a, the larger the opening of the free ends of the two guide portions 113a1, the two guide portions 113a1 can smoothly extend into the space between the two guide portions 113a1, and then even if the free ends of the two support arms 310 continue to extend, the support arms 310 are constrained and guided by the guide portions 113a1 until the two support arms 310 both extend into the space between the two second positioning tables 113 a. Therefore, the structural layout can reduce the operation difficulty of aligning the two support arms 310 and extending into the two second positioning tables 113a, and also improve the operation convenience and smoothness.

Specifically, as shown in fig. 5, the third positioning member 114 according to the embodiment of the present application may be a T-shaped structural member, two avoidance spaces 114a are disposed on two opposite sides of the third positioning member 114, the two avoidance spaces 114a are respectively used for two support arms 310 to pass through, and the two support arms 310 are in positioning fit with the third positioning member 114 in the third direction. Under such a configuration, since the third positioning element 114 is a T-shaped structural member, and the two avoidance spaces 114a are through regions, the two support arms 310 can smoothly pass through the two avoidance spaces 114a, at this time, the two support arms 310 are located between the inner wall of the cover 110 and the positioning element, so that the third positioning element 114 can position the support arms 310 in the Z-axis direction, and further determine the Z-coordinate of the limiting element 300.

In another embodiment, the third positioning element 114 may also be an L-shaped structural element, one end of which is connected to the inner wall of the cover 110, and the other end of which is bent to be parallel to the inner wall of the cover 110, so as to position the two arms 310 in the Z-axis direction.

Further, as shown in fig. 5, fig. 6, fig. 8 and fig. 9, the third positioning element 114 of the embodiment of the present application may be disposed corresponding to the avoiding hole 111, and the third positioning element 114 is provided with a receiving groove 114b, where the receiving groove 114b is used for receiving the clamping element 220. It should be understood that when the arm 310 interferes with the protrusion 222a, the portion of the arm 310 directly contacting the protrusion 222a generates the largest amount of deformation, that is, the portion of the arm 310 corresponding to the avoiding hole 111 generates the largest amount of deformation; because the third positioning element 114 of the embodiment of the present application is disposed corresponding to the avoiding hole 111, under such a situation, the third positioning element 114 can restrict the support arm 310, so as to prevent the support arm 310 from deforming and exceeding the yield strength thereof; meanwhile, after the support arm 310 is retracted and passes through the protrusion 222a, the latch member 220 extends into the wall-mounted whole machine 100, and the accommodating groove 114b can accommodate the latch member 220, thereby preventing the latch member 220 from interfering with the third positioning member 114.

In an alternative, as shown in fig. 5, the third positioning element 114 of the embodiment of the present application may be located between the first positioning element 112 and the second positioning element 113. With this arrangement, the positioning action of the limiting element 300 in the Z-axis direction is located at the middle portion, so that the distribution of the positioning action of the limiting element 300 on the inner wall of the cover 110 is more balanced, and the situation that the limiting element 300 is separated from the first positioning element 112 or the second positioning element 113 due to the insufficient positioning action of the connecting section 320 side or the free end side of the supporting arm 310 in the Z-axis direction can be avoided. Therefore, the structural layout can optimize the installation stability of the limiting member 300.

With reference to the foregoing embodiments, as shown in fig. 3 and fig. 4, in a specific process of installing the position-limiting member 300, first, the position-limiting member 300 can be picked up and the free ends of the two support arms 310 are extended into the avoiding space 114a on both sides of the third positioning member 114, then the position-limiting member 300 is pushed to move toward the second positioning member 113, and the connection section 320 of the position-limiting member 300 is pressed downward until the free ends of the two support arms 310 are extended between the two second positioning stages 113a by being guided by the guide portion 113a1, and at the same time, the connection section 320 is also pressed downward to enter between the two first positioning stages 112a, which is the installation process of the position-limiting member 300.

In the embodiments of the present application, the difference between the embodiments is described in detail, and different optimization features between the embodiments can be combined to form a better embodiment as long as the differences are not contradictory, and further description is omitted here in view of brevity of the text.

The above description is only an example of the present application and is not intended to limit the present application. Various modifications and changes may occur to those skilled in the art to which the present application pertains. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
