When the elastic sheet 420 has an external force, the elastic sheet 420 can be elastically deformed, so that the elastic sheet 420 moves from the first position to the second position. In one embodiment, the spring 420 has a first inclined plane 421, the bottom plate 410 is further provided with a through hole 412, the through hole 412 can be communicated with the accommodating slot 411, and an axis extension line of the through hole 412 can pass through the first inclined plane 421, so that the thimble 100 can pass through the through hole 412 and slide along the first inclined plane 421.
Referring to fig. 2,3 and 5, in one embodiment, a limiting groove 310 is formed on a side of the doorbell assembly 300 facing the bottom plate 410, when the doorbell assembly 300 is mounted on the bottom plate 410, a part of the structure of the spring plate 420 can be clamped in the limiting groove 310, and the doorbell assembly 300 and the bottom plate 410 are relatively stationary and are in a fixed state, so that the doorbell assembly 300 and the bottom plate 410 are assembled. Specifically, when the user needs to detach the doorbell assembly 300 from the bottom plate 410, the user can pick up the thimble 100, so that the thimble 100 passes through the through hole 412 and slides along the first inclined plane 421, and slides between the doorbell assembly 300 and the shrapnel 420, and the shrapnel 420 deforms due to extrusion of the thimble 100, so that the shrapnel 420 moves from the first position to the second position, that is, at this time, a part of the structure of the shrapnel 420 breaks away from the limit groove 310, thereby realizing separation of the doorbell assembly 300 and the base 400. It can be appreciated that the included angle between the first inclined plane 421 and the forward direction of the base 400 is 20-40 degrees, the more optimized included angle between the first inclined plane 421 and the forward direction of the base 400 is about 30 degrees, the first inclined plane 421 located at the angle can help the thimble 100 slide more smoothly on the first inclined plane 421, which is more beneficial for the thimble 100 to slide from the first inclined plane 421 to between the doorbell assembly 300 and the spring 420, and helps the part of the structure of the spring 420 to separate from the limiting groove 310.
Referring to fig. 4 and 5, in one embodiment, the elastic sheet 420 includes a connecting portion 422 and an acting portion 423 connected to the connecting portion 422, the connecting portion 422 is connected to a groove wall of the accommodating groove 411, the acting portion 423 is spaced from the groove wall of the accommodating groove 411, the acting portion 423 is provided with a sliding groove 424, and the first inclined plane 421 is located at a groove bottom of the sliding groove 424. Referring to fig. 2 in particular, chute 424 is a generally C-shaped slot, and chute 424 has opposing first and second openings, and thimble 100 is able to enter from the first opening of chute 424, slide out through first ramp 421 and from the opposing second opening to the surface of connecting portion 422, so that thimble 100 is located between dome 420 and doorbell assembly 300. It can be appreciated that when the thimble 100 slides on the first inclined plane 421, that is, when the thimble 100 slides on the bottom of the chute 424, the chute wall of the chute 424 has a guiding function to the sliding of the thimble 100, so as to prevent deviation caused by ambiguous sliding route of the thimble 100. In one embodiment, a protrusion 425 is disposed on a side of the acting portion 423 facing the doorbell assembly 300, the protrusion 425 protrudes from the bottom plate 410, and the shape of the protrusion 425 is matched with the shape of the limiting groove 310, so that the protrusion 425 can be clamped in the limiting groove 310. When the thimble 100 slides between the doorbell assembly 300 and the elastic piece 420 through the through hole 412 and the first inclined plane 421, the elastic piece 420 deforms, and the elastic piece 420 moves from the first position to the second position, i.e. the protrusion 425 is converted from a state of being clamped in the limiting groove 310 to a state of being separated from the limiting groove 310, so that the doorbell assembly 300 is separated from the bottom plate 410. Specifically, the height of the thimble 100 is greater than or equal to the height of the protrusion 425, the height of the protrusion 425 may be the height of the protrusion 425 accommodated in the limit groove 310, and when the thimble 100 is positioned between the doorbell assembly 300 and the elastic sheet 420, due to the height setting of the thimble 100, the protrusion 425 can completely withdraw from the limit groove 310, so that the part of the structure of the protrusion 425 is effectively prevented from being accommodated in the limit groove 310, and the separation of the doorbell assembly 300 and the bottom plate 410 is hindered.
In one embodiment, the width of the connection portion 422 and the width of the acting portion 423 may be different, and may be adjusted according to the user's needs, i.e., the width of the connection portion 422 may be less than or equal to the width of the acting portion 423. Specifically, when the user desires to assemble the doorbell assembly 300 with the base 400 more flexibly, the width of the connecting portion 422 may be set smaller than the width of the acting portion 423, so that when the user acts the thimble 100 on the first inclined surface 421 on the acting portion 423, the radian of the deformation of the connecting portion 422 is larger, and the user does not apply a larger pressure to the thimble 100, and the elastic piece 420 may deform and move from the first position to the second position and separate from the limiting groove 310, so that the thimble 100 and the elastic piece 420 are more sensitively matched. When the user wants the anti-disassembly performance of the doorbell assembly 300 assembled with the base 400 to be higher, the connecting portion 422 can be set to be equal to or slightly larger than the width of the acting portion 423, so that when the user acts the thimble 100 on the first inclined surface 421 on the acting portion 423, the connecting portion 422 is not easy to deform, and then the user needs to apply larger pressure to the thimble 100, the elastic sheet 420 can deform and separate from the limiting groove 310, so that the doorbell assembly 300 and the base 400 are assembled more firmly.
Referring to fig. 2 and 4, in one embodiment, the bottom plate 410 is provided with a clamping groove 413, and a hook 320 is disposed on a side of the doorbell assembly 300 facing the bottom plate 410, and the hook 320 can be clamped in the clamping groove 413. The mutual clamping action of the clamping hook 320 and the clamping groove 413 can further stabilize the assembly between the doorbell assembly 300 and the bottom plate 410, which is beneficial to the doorbell assembly 300 not being easily separated from the bottom plate 410. Referring to fig. 6, in one embodiment, the clamping groove 413 includes a first clamping groove 4131 and a second clamping groove 4132, the first clamping groove 4131 communicates with the second clamping groove 4132, and the maximum width of the first clamping groove 4131 is greater than the maximum width of the second clamping groove 4132. Further, the first clamping groove 4131 may penetrate through two sides of the bottom plate 410, and the maximum width of the first clamping groove 4131 should be larger than the maximum width of the hook 320, so that the hook 320 may penetrate into the first clamping groove 4131, after the hook 320 passes through the first clamping groove 4131, the doorbell assembly 300 may slide in a reverse direction, at this time, the hook 320 is clamped in the second clamping groove 4132, and the protrusion 425 of the spring 420 is also clamped in the limiting groove 310 while the hook 320 is clamped, and the doorbell assembly 300 may be more firmly mounted on the bottom plate 410 due to the joint clamping of the hook 320 and the protrusion 425. Specifically, when the hook 320 is clamped in the second clamping groove 4132, the doorbell assembly 300 is not limited at this time, that is, the doorbell assembly 300 may still slide, so that the hook 320 may be separated from the second clamping groove 4132, and the protrusion 425 is clamped in the limiting groove 310, so that the position between the doorbell assembly 300 and the bottom plate 410 is effectively limited, and the doorbell assembly 300 and the bottom plate 410 are prevented from being separated, so that the doorbell assembly 300 and the bottom plate 410 are more firmly assembled.
Referring to fig. 5, in one embodiment, the protrusion 425 has a grip surface 4251, a transition surface 4252, and a second sloped surface 4253, the transition surface 4252 being located between the grip surface 4251 and the second sloped surface 4253. Referring to fig. 2, in the process of assembling the doorbell assembly 300 with the base 400, the hook 320 of the doorbell assembly 300 is first aligned with the first clamping groove 4131, so that the hook 320 penetrates into the first clamping groove 4131, at this time, the elastic piece 420 abuts against the doorbell assembly 300 and deforms, the user continues to slide the doorbell assembly 300 in the opposite direction, so that the hook 320 moves to clamp in the second clamping groove 4132, and the elastic piece 420 moves to the position of the limiting groove 310, i.e. moves to the first position to clamp in the limiting groove 310. It can be appreciated that, when the elastic piece 420 is in the process from abutting the doorbell assembly 300 to being clamped in the limiting groove 310, the elastic piece 420 abuts against the doorbell assembly 300 and deforms, the doorbell assembly 300 continues to move to slide along the second inclined plane 4253, and slide from the second inclined plane 4253 to pass through the transition surface 4252, and finally moves to the position where the limiting groove 310 is opposite to the protrusion 425 of the elastic piece 420, at this time, the elastic piece 420 resumes to deform and is located at the first position, and the protrusion 425 is clamped in the limiting groove 310.
It will be appreciated that when the user wishes to separate the doorbell assembly 300 from the base 400, the user may first slide the thimble 100 between the doorbell assembly 300 and the base 400 through the through hole 412 and along the first inclined plane 421, at this time, the protrusion 425 of the spring 420 is separated from the limiting groove 310, and then the user may push the doorbell assembly 300 with his or her hand to push the doorbell assembly 300 forward (forward and reverse directions are opposite), at this time, the hook 320 may move from the position clamped in the second clamping groove 4132 to the position accommodated in the first clamping groove 4131, and the user then lifts the doorbell assembly 300 from the base 400, so as to separate the doorbell assembly 300 from the base 400.
The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
