The snap assembly 10 may be used to connect a first component 20 and a second component 30. The snap assembly 10 may include: a fixed arm 11, a pair of first elastic cantilevers 12, and a second elastic cantilever 13.

The fixing arm 11 is provided to the first member 20. Wherein, the fixing arm 11 can be integrally formed on the first component 20 as a part of the first component 20; the securing arm 11 may also be removably attached to the first member 20, such as by bonding or mating fasteners or the like to the first member 20 to secure the arm 11 to the first member.

In some embodiments, the securing arm 11 is configured to be rigid such that the securing arm 11 has a certain strength.

The second member 30 is provided with a mounting opening 31, and the mounting opening 31 is used for passing through the fixing arm 11. The pair of first elastic cantilevers 12 are disposed at the edge of the mounting opening 31 and respectively abut against the pair of first stopping surfaces 111 of the fixing arm 11. The movement of the fixing arm 11 in the first direction and the second direction can be restricted by the engagement of the pair of first elastic cantilevers 12 with the pair of first stopping surfaces 111. The first direction is a direction in which one of the pair of first elastic cantilevers 12 points toward the other. The second direction is the extending direction of the fixing arm 11. By restricting the movement of the fixed arm 11 in the second direction, the fixed arm 11 can be prevented from breaking loose its abutment by the pair of first elastic cantilevers 12 in the second direction.

The second elastic cantilever 13 is disposed at the edge of the mounting opening 31 and abuts against the second stopping surface 112 of the fixing arm 11 to limit the movement of the fixing arm 11 in a third direction, which intersects with the first direction.

In some implementations, the first direction and the third direction are both directions parallel to a plane of the first component 20.

As can be seen from the above, the fixed arm 11 is disposed on the first part 20, the pair of first elastic cantilevers 12 is disposed at the edge of the mounting opening 31 of the second part 30, the pair of first elastic cantilevers 12 respectively abut against the pair of first stopping surfaces 111 of the fixed arm 11 to limit the movement of the fixed arm 11 in the first direction and the second direction, the first direction is a direction in which one of the pair of first elastic cantilevers 12 points to the other, the second direction is an extending direction of the fixed arm 11, and the second elastic cantilever 13 disposed at the edge of the mounting opening 31 can abut against the second stopping surface 112 of the fixed arm 11 to limit the movement of the fixed arm 11 in the third direction. When the movement of the fixing arm 11 is limited in the second direction of the extension of the fixing arm 11, the movement of the fixing arm 11 is limited in the first direction and the third direction which are in an intersecting relationship, so that the fixing arm 11 can be effectively prevented from rotating around the extension direction of the fixing arm, a pair of first elastic cantilevers 12 can be respectively and stably and uniformly abutted against a pair of first retaining surfaces 111, the anti-overturning performance and the retaining performance of the buckle assembly 10 can be improved, and the buckling connection firmness of the buckle assembly 10 can be improved.

Further, the movement of the fixing arm 11 in the first direction and the second direction is restricted by the pair of first elastic cantilevers 12 engaging with the first stopper surface 111. Through second elastic cantilever 13 cooperation second stopping face 112, restrict the motion of fixed arm 11 in the third direction, respectively in the first direction with the help of a pair of first elastic cantilever 12 and second elastic cantilever 13, the motion of fixed arm 11 is restricted simultaneously in second direction and third direction, come the stopping and anti upset, can reduce fixed arm 11 to the dependence that relies on intensity of self stopping and anti upset, thereby realize even reducing fixed arm 11's size, buckle component 10 still has better stopping and anti upset performance. Therefore, the buckle assembly 10 provided by the embodiment of the present invention can also reduce the size of the mounting opening 31 by reducing the size of the fixing arm 11 under the condition of considering both the anti-flipping performance and the retaining performance, so as to reduce the space occupation of the buckle assembly 10 on the first component 20 and the second component 30, and be suitable for a scene with a severe requirement on space.

Generally, the fixing arm 11 is disposed on the side of the first component 20 facing the second component 30, and the pair of first elastic cantilever 12 and second elastic cantilever 13 is disposed on the side of the second component 30 away from the first component 20, so that when other components are required to be mounted between the first component 20 and the second component 30 or other processes such as bonding, welding or sealing are performed, the size of the mounting opening 31 is reduced, and the space occupied by the buckle assembly 10 on the first component 20 and the second component 30 is reduced, thereby facilitating the provision of sufficient space for the mounting of other components or other processes.

In an implementation, the first elastic cantilever 12 may include a root portion 121 and a free end 122, the root portion 121 of the first elastic cantilever 12 is connected to the edge of the mounting opening 31, and the free end 122 of the first elastic cantilever 12 is spaced apart from the second component 30.

A pair of first resilient cantilevers 12 may be integrally formed at the edge of the mounting opening 31 as a part of the second member 30; a pair of first resilient cantilevers 12 may also be detachably connected to the edge of the mounting opening 31, independently of the second member 30.

In an implementation, the pair of first elastic cantilevers 12 and the second elastic cantilever 13 are both inclined toward the center of the mounting opening 31, and a gap between the hanging ends 122 of the pair of first elastic cantilevers 12 is smaller than the maximum dimension of the fixing arm 11. Specifically, the gap between the free ends 122 of the pair of first elastic cantilevers 12 is smaller than the maximum relative distance between the surfaces of the pair of first backstop surfaces 111. Wherein the gap between the free ends 122 of the pair of first elastic cantilevers 12 refers to the relative distance between the free ends 122 of the pair of first elastic cantilevers 12.

Regardless of the manner of the first elastic cantilever 12 disposed on the mounting opening 31, the first elastic cantilever 12 can move toward the center away from the mounting opening 31 under the action of the external force, and the suspended end 122 of the first elastic cantilever 12 can automatically return to the initial position in the free state after the external force disappears or decreases. The free state refers to a state in which no external force acts.

Under the action of the external force, the free end 131 of the second elastic cantilever 13 can move away from the center of the mounting opening 31, and can automatically return to the original position in the free state after the external force disappears or is reduced.

In a specific implementation, the pair of first elastic cantilevers 12 are disposed opposite to each other to uniformly abut against the pair of first anti-backing surfaces 111, so as to improve the anti-backing performance of the buckle assembly. When the shape of the mounting opening 31 is rectangular or square, the mounting opening 31 may have four edges. A pair of first resilient cantilever arms 12 may be provided along opposite edges of the mounting opening 31, respectively. Further, the second elastic cantilever 13 may be disposed along one of the remaining two edges.

In some non-limiting embodiments, the relative distance between the second anti-backup surface 112 and the top 114 of the fixing arm 11 is greater than the relative distance between the first anti-backup surface 111 and the top 114 of the fixing arm 11. So that the relative distance of the first resilient cantilever 12 to the second part 30 is smaller than the distance of the second resilient cantilever 13 to the second part 30. The size of the first resilient cantilever 12 is expected to be small towards the volume of the design.

In a specific implementation, at the top 114 of the fixing arm 11, the second stopping surface 112 is formed to protrude along the surface of the fixing arm 11 toward a direction away from the surface.

In some embodiments, referring to fig. 10, an included angle β between the second anti-backup surface 112 and the fixing arm 11 is an obtuse angle, so as to achieve the abutting between the second anti-backup surface 112 and the second elastic cantilever 13, and facilitate the releasing of the abutting between the second elastic cantilever 13 and the second anti-backup surface 112 when the connection between the first component 20 and the second component 30 is released.

Further, the top of the fixing arm 11 is provided with an installation lead-in angle, so that when the buckle assembly 10 is installed, the clamping force of the second elastic cantilever 13 on the fixing arm 11 can be reduced, and the installation of the buckle assembly 10 is facilitated.

In a specific implementation, between the top portion 114 of the fixing arm 11 and the root portion 113 of the fixing arm 11, a first stop surface 111 is formed to protrude along the surface of the fixing arm 11 in a direction away from the surface.

In some embodiments, referring to fig. 9, an included angle θ between the first anti-backup surface 111 and the fixing arm 11 is an obtuse angle, so as to achieve the abutting between the first anti-backup surface 111 and the first elastic cantilever 12, and facilitate the releasing of the abutting between the first elastic cantilever 12 and the first anti-backup surface 111 when the connection between the first component 20 and the second component 30 is released.

In a specific implementation, the size of the mounting opening 31 is enough to pass through the fixing arm 11, and the specific size can be configured according to the shape of the fixing arm 11. After the fixed arm 11 passes through the mounting opening 31, the second elastic cantilever 13 passes over the pair of first elastic cantilevers 12, and then the pair of first stopping surfaces 111 push the corresponding pair of first elastic cantilevers 12, and the pair of first elastic cantilevers 12 move away from the center of the mounting opening 31 under the action of the corresponding first stopping surfaces 111, and the gap between the suspended ends of the pair of first elastic cantilevers 12 gradually increases. When the pair of first stopping surfaces 111 pass over the pair of first elastic cantilevers 12, the pair of first elastic cantilevers 12 moves toward the center direction of the mounting opening 31 and returns toward the initial position in the free state until the pair of first elastic cantilevers 12 respectively abut against the corresponding pair of first stopping surfaces 111. The second stopping surface 112 pushes the second elastic cantilever 13, and the second elastic cantilever 13 moves in a direction away from the center of the mounting opening 31 under the pushing of the second stopping surface 112. After the second stopping surface 112 passes over the second elastic cantilever 13, the second elastic cantilever 13 moves toward the center of the mounting opening 31 and returns to the initial position in the free state as much as possible until the second elastic cantilever 13 abuts against the second stopping surface 112.

In a specific implementation, the buckle assembly 10 may further include a support rib 14, and the support rib 14 is connected to the fixing arm 11 to reinforce the strength of the fixing arm 11. In some embodiments, the support rib 14 is integrally formed with the fixing arm 11 as a part of the fixing arm 11, and may be connected to the fixing arm 11 by bonding, welding, riveting, or other methods. The specific connection manner of the support rib 14 and the fixing arm 11 may be configured according to an actual application scenario, a material of the fixing arm 11, a material of the support rib 14, and the like, and is not limited herein.

In a specific implementation, the cross-sectional dimension of the support rib 14 is gradually reduced along the direction from the root 113 of the fixing arm 11 to the top 114 of the fixing arm 11. Wherein the root portion 113 of said fixed arm 11 is connected to said first part 20.

In some non-limiting embodiments, the shape of the mounting opening 31 corresponding to one side of the support rib 14 is matched with the shape of the support rib 14, so as to facilitate the mounting of the fixing arm.

Further, the buckle assembly 10 may further include a limiting portion 15 disposed at an edge of the mounting opening 31, and the fixing arm 11 is located between the second elastic cantilever 13 and the limiting portion 15, and is configured to limit the fixing arm 11 to move between the second elastic cantilever 13 and the limiting portion 15. The pair of first elastic cantilevers 12, the second elastic cantilever 13 and the limiting portion 15 may form an enclosing structure, and support the fixing arm 11 from four different areas, so as to further improve the anti-flipping performance and the retaining performance of the buckle assembly 10.

In some implementations, the stop 15 may be an edge of the mounting opening 31, such that the mounting opening 31 may be closed, as shown in fig. 11.

In other embodiments, when the stopper portion 15 is not provided, the mounting opening 31 is open, as shown in fig. 12. The specific shape of the mounting opening 31 may be configured according to the requirements of the actual application and the structure of the second member 30.

In a specific implementation, referring to fig. 8, in order to ensure that the second elastic cantilever 13 has a good elasticity, the installation of the fixing arm 11 is facilitated while the fixing arm 11 is prevented from moving backwards. The length and the wall thickness of the second elastic cantilever 13 need to satisfy a preset proportional relationship. For example, the ratio of the length L of the second elastic cantilever 13 to the wall thickness T is not less than 5. It can be understood that the length L and the wall thickness T of the second elastic cantilever 13 may have other values according to the requirement of the elasticity of the second elastic cantilever 13.

The utility model also provides a control panel, which comprises a panel main body, a decorative piece and at least one buckle assembly 10, wherein one of the panel main body and the decorative piece is the first part, and the other of the panel main body and the decorative piece is the second part 30. The snap assembly 10 may adopt the snap assembly 10 provided in any of the above embodiments, and the detailed structure of the snap assembly 10 may refer to the description in the above embodiments, which is not described herein again.

In some embodiments, referring to fig. 1, when the second member 30 is a panel body and the first member 20 is a decorative member, it is generally necessary to mount other parts, such as a display screen of a panel system, etc., in the x-direction of the second member 30. Thus, in the x-direction, the smaller the space occupied by the snap assembly 10, the better. In the buckle assembly provided by the embodiment of the utility model, the movement of the fixed arm 11 is limited simultaneously in the first direction, the second direction and the third direction by the pair of the first elastic cantilever 12 and the second elastic cantilever 13 respectively to stop and resist the backward movement, so that the dependence of the fixed arm 11 on the strength of the fixed arm 11 to stop and resist the backward movement can be reduced, and the buckle assembly 10 still has better performance of stopping and resisting the backward movement even if the size of the fixed arm 11 is reduced. Therefore, the buckle assembly 10 provided by the embodiment of the utility model can also reduce the size of the mounting opening 31 by reducing the size of the fixing arm 11 under the condition of simultaneously considering the anti-overturning performance and the backstop performance, so as to reduce the space occupation of the buckle assembly 10 on the first part 20 and the second part 30.

Further, since the size of the mounting opening 31 can be reduced, the second elastic cantilever 13 is disposed on a side of the second member 30 away from the first member 20 and on the edge of the mounting opening 31, and therefore, in the x direction, the contact area between the side of the second member 30 facing the first member 20 and the first member 20 can be increased to facilitate other operations between the second member 30 and the first member 20.

In the specific implementation, the control panel is a control panel of a household appliance, and can also be a control panel of other equipment. The household appliances can be a washing machine, a dryer, a washing and drying integrated machine and the like.
