Example 1:
referring to fig. 1-4, an anti-falling type intelligent television remote controller comprises a shell 1, wherein the shell 1 is an outer plastic shell of the television remote controller, and U-shaped sleeves 2 sleeved at two ends of the shell 1, the number of the U-shaped sleeves 2 is 2 groups, a cavity 201 is arranged in each U-shaped sleeve 2, one end of each U-shaped sleeve is in an open shape, each U-shaped sleeve 2 is sleeved at two ends of the shell 1 through the cavity 201 and is sleeved on a buffer shell 202 on the periphery of each U-shaped sleeve 2, the number of the buffer shells 202 is also 2 groups, the anti-falling type intelligent television remote controller further comprises a buffer mechanism used for connecting the U-shaped sleeves 2 and the buffer shells 202, and the buffer mechanism comprises a buffer mechanism.
The buffer mechanism comprises a set of third elastic plates 601 connected to the top and the bottom of the U-shaped sleeve 2 in a sliding manner, namely, two sets of the third elastic plates 601 are respectively positioned at the top and the bottom of the U-shaped sleeve 2, a first elastic plate 301 connected to the side wall of the U-shaped sleeve 2 in a sliding manner, and a second elastic plate 401 connected to the front end of the U-shaped sleeve 2 in a sliding manner; the other ends of the first elastic plate 301, the second elastic plate 401 and the third elastic plate 601 are connected with the inner wall of the buffer shell 202.
The first elastic plate 301, the second elastic plate 401 and the third elastic plate 601 are made of elastic materials, the other ends of the first elastic plate 301, the second elastic plate 401 and the third elastic plate 601 can abut against the inner wall of the buffer shell 202, and can also be fixedly connected, and the first elastic plate 301, the second elastic plate 401 and the third elastic plate 601 are in a hand bending state.
The buffer mechanisms are designed into four groups, which are respectively positioned at four corners of the shell 1, that is, two groups are respectively positioned in the buffer shell 202 at the front end and the rear end of the shell 1.
In the use, in case shell 1 falls from the eminence, because the thickness of buffering shell 202 is greater than the thickness of shell 1, so, buffering shell 202 can at first contact with ground to, shell 1 can be in unsettled state always, and at this moment, buffering shell 202 is when contacting with ground, through the buffer gear in shell 1 four corners, offsets the impact force that falls from the eminence, prevents that the impact force from directly acting on shell 1 surface, when the effectual shell 1 of having protected falls from the eminence, the integrated circuit board of inside is damaged.
Shell 1 falls from the eminence, and buffer shell 202 is when contacting with ground, if top and bottom contact with ground earlier, this moment, buffer shell 202 stop motion suddenly receives the influence of impact force, and U type cover 2 can continue to take shell 1 that is in unsettled state to continue to remove to ground one side, and at this moment, the third elastic plate 601 that is close to ground one side receives the extrusion, and the bending angle grow absorbs impact force, reaches and offsets the effect.
When the U-shaped sleeve 2 is carried with the shell 1 in a suspended state to move towards one side of the ground, the first elastic plate 301 and the second elastic plate 401 are abutted against the side wall of the U-shaped sleeve 2, and when the U-shaped sleeve 2 moves, the U-shaped sleeve 2 can rub against the first elastic plate 301 and the second elastic plate 401 on two sides, so that impact force is further counteracted, and the integrated circuit board inside is prevented from being damaged.
Similarly, if the side wall or the front and rear ends of the housing 1 contact the ground first, the first elastic plate 301 or the second elastic plate 401 is pressed to play a role of buffering.
The open end of the U-shaped sleeve 2 is inclined outward in the circumferential direction, which is favorable for inserting the housing 1 into the cavity 201.
The shell 1 falls from the eminence, and when the buffer shell 202 contacted ground, the reaction force of first elastic plate 301, second elastic plate 401 and third elastic plate 601 only can be exerted at U type cover 2 outside lateral wall, makes inside shell 1 atress even, prevents because the atress concentrates, leads to producing the deformation, even damage.
Example 2:
referring to fig. 1-4, on the basis of example 1, further,
the fifth sliding plates 6 are connected to the top and the bottom of the U-shaped sleeve 2 in a sliding mode, and the third elastic plates 601 are fixed on the fifth sliding plates 6; the first sliding plate 3 is connected to the side wall of the U-shaped sleeve 2 in a sliding mode, and the first elastic plate 301 is fixed on the first sliding plate 3; a third sliding plate 4 slidably connected to the front end of the U-shaped casing 2, and a second elastic plate 401 fixed to the third sliding plate 4.
The shell 1 falls from the eminence, and when the buffer shell 202 contacted with ground, the third elastic plate 601 accessible fifth sliding plate 6 slided at U type cover 2 surface, and first elastic plate 301 passes through first sliding plate 3, and second elastic plate 401 passes through third sliding plate 4, slides at U type cover 2 surface, makes to slide more steadily, prevents because the impact force of dropping, leads to first elastic plate 301 or second elastic plate 401 or third elastic plate 601 slope, loses elasticity.
The other ends of the first elastic plate 301, the second elastic plate 401 and the third elastic plate 601 can abut against the inner wall of the buffer shell 202, and the buffer device further comprises a second sliding plate 302 fixed at the other end of the first elastic plate 301 and a fourth sliding plate 402 fixed at the other end of the second elastic plate 401, wherein the second sliding plate 302 and the fourth sliding plate 402 are slidably connected with the inner wall of the buffer shell 202.
The first elastic plate 301 and the second elastic plate 401 can flexibly slide between the U-shaped sleeve 2 and the buffer shell 202 through the second sliding plate 302 and the fourth sliding plate 402, so that the stability is improved, and complicated acting force which falls from a high place and appears at any angle is used.
Shell 1 falls from the eminence, and when buffering shell 202 contacted with ground, because shell 1 top and bottom are two the biggest faces of area, so, at the in-process that falls, these two faces are at first the biggest with the possibility of ground contact, so, for improving stability, with the other end and the buffering shell 202 inner wall fixed connection of third elastic plate 601, and then effectively prevent the slope of third elastic plate 601, lose elasticity.
