As shown in fig. 1, in this embodiment, the fixing base 2, the control member 3, and the protection member 4 are all formed by injection molding or casting, so that the cost is low, and the elastic member 5, the control member 3, and the protection member 4 are sequentially assembled to the fixing base 2, so as to complete the assembly of the anti-collision protection device 1 of the display device, simplify the structure of the anti-collision protection device 1 of the display device, make the anti-collision protection device 1 of the display device compact, and facilitate reducing the size of the anti-collision protection device 1 of the display device.
Example two
Referring to fig. 3 to 6, the second embodiment of the present invention provides another technical solution for the structures of the fixing base 2 and the control member 3 based on the first embodiment, which is different from the first embodiment only in the structure of the fixing base 2 and the control member 3.
As shown in fig. 3 and 5, in this embodiment, a second protruding guiding portion 21 is disposed on an outer side wall of the fixing base 2, a second guiding groove 32 matched with the second guiding portion 21 is disposed on the control element 3, the second guiding portion 21 extends into the second guiding groove 32 and abuts against the protection member 4, an included angle between a length direction of the second guiding groove 32 and a vertical direction is an acute angle, and then when the control element 3 moves relative to the fixing base 2 by pressing the pressing portion 34, the control element 3 moves along the length direction of the second guiding groove 32, so that the control element 3 moves along the horizontal direction while moving along the horizontal direction close to the fixing base 2 or moves along the vertical direction while moving along the horizontal direction away from the fixing base 2, and further, in the moving process of the control element 3, the protection plate 41 also moves along the horizontal direction away from the fixing base 2 while moving along the vertical direction up or along the horizontal direction close to the fixing base 2 while moving along the vertical direction down, so that the protection plate 41 completely extends out of a display unit of the LED display screen or retracts into the display unit of the LED display device 1, and further reducing the volume of the display device.
In detail, when the control member 3 is pressed to move the control member 3 relative to the fixing base 2 and drive the protection member 4 to move, the second guide portion 21 abuts against the second guide groove 32 to move the control member 3 under the guidance of the second guide groove 32, and drives the first guide portion 31 to abut against the first guide groove 42 to move the protection member 4 synchronously. And the direction in which the first guide part 31 moves in the horizontal direction in the first guide groove 42 is the same as the direction in which the second guide part 21 moves in the horizontal direction in the second guide groove 32 when the check member 3 is actuated, and the direction in which the first guide part 31 moves in the vertical direction in the first guide groove 42 is opposite to the direction in which the second guide part 21 moves in the vertical direction in the second guide groove 32. That is, when the protection member 4 retracts, the control member 3 moves relative to the fixing base 2 in the horizontal direction and the vertical direction simultaneously, so that the protection member 4 moves in the horizontal direction relative to the fixing base 2 and approaches the fixing base 2 under the guidance of the cooperation between the first guide portion 31 and the first guide groove 42 and the cooperation between the third guide portion 45 and the third guide groove 22; when the protection member 4 extends, the control member 3 moves relative to the fixing base 2 in the horizontal direction and the vertical direction simultaneously, so that the protection member 4 moves horizontally relative to the fixing base 2 and is away from the fixing base 2 under the guidance of the cooperation between the first guide portion 31 and the first guide groove 42 and the cooperation between the third guide portion 45 and the third guide groove 22.
Specifically, when the control member 3 moves relative to the fixed seat 2, the stroke of the first guide portion 31 moving in the vertical direction in the first guide groove 42 is smaller than the stroke of the second guide portion 21 moving in the vertical direction in the second guide groove 32. That is, in the retracting process of the protection member 4, after the protection member 4 moves a certain distance in the horizontal direction relative to the fixing seat 2, the first guide portion 31 abuts against the end of the first guide groove 42, and at this time, the third guide portion 45 is separated from the third guide groove 22, the second guide portion 21 continues to move in the vertical direction in the second guide groove 32, so that the protection member 4 moves a certain distance in the vertical direction and approaches the fixing seat 2 under the driving of the control member 3, so that the protection member 4 is completely retracted into the fixing seat 2; protection piece 4 is at the in-process that stretches out, second guide part 21 removes one end distance along vertical direction earlier in second guide way 32, and then first guide part 31 supports under the drive of control 3 and holds protection piece 4 and orders about protection piece 4 and remove along vertical direction, make protection piece 4 keep away from fixing base 2 along vertical direction earlier, third guide part 45 supports with fixing base 2 and holds and aligns with third guide way 22 this moment, rethread control 3 drives protection piece 4 and keeps away from fixing base 2 along the horizontal direction and realizes the action of stretching out of protection piece 4.
As shown in fig. 5, the two opposite ends of the second guide groove 32 are respectively provided with a second friction portion 33, and when the crash protection device 1 of the display device is in the expanded state or the collapsed state, the second guide portion 21 abuts against one of the second friction portions 33, so that the crash protection device 1 of the display device is kept in the expanded state or the collapsed state.
Referring to fig. 4 and 6, when the anti-collision protection device 1 of the display device is changed from the unfolded state to the folded state, the third guide portion 45 exits the third guide groove 22 and moves downward along the vertical direction at the same time as the protection member 4 by a certain distance, and when the anti-collision protection device 1 of the display device is changed from the folded state to the unfolded state, the third guide portion 45 moves vertically first to align with the third guide groove 22 and then extends into the third guide groove 22 along the length direction of the third guide groove 22, so as to ensure that the protection plate 41 moves horizontally by a sufficient distance to extend out of the display unit of the LED display screen.
In this embodiment, the fixing base 2, the control member 3 and the protection member 4 are respectively provided with a guiding mechanism, and the first guiding portion 31 and the second guiding portion 21 arranged at intervals enable the control member 3 to move for a short stroke to drive the protection member 4 to extend or retract relative to the fixing base 2, so that the overall structure of the anti-collision protection device 1 of the display device is compact, and the space occupied by the anti-collision protection device 1 of the display device is reduced.
