The front side of the desktop panel 1 is provided with a control switch 5, the two electric push rods are electrically connected with the control switch 5, and the electric push rods can be controlled to be extended or retracted through the buttons on the control switch 5, so that the height of the table legs 2 can be changed.
[0029] In the embodiment, the bottom plate 22 can increase the contact area with the ground and can further improve the stability of the study table as a counterweight.
[0030] As shown in Figure 3 , Figure 4 and Figure 5 , the anti-collision device 3 comprises an anti-collision block 31 and a locking block 34.
[0031] In the embodiment, the anti-collision block 31 is in a strip shape and is chamfered at both ends. When the anti-collision block 31 works, the lower surface thereof is flush with the lower surface of the desktop panel 1. The anti-collision block 31 is concave in the surface adhered to the desktop panel 1 to form an inner recess 32, the inner recess 32 is matched with the side walls of the desktop panel 1, and the anti-collision block 31 can be clamped on the two sides of the desktop panel 1 through the inner recess 32.
[0032] In the embodiment, the anti-collision block 31 is fixedly connected with the desktop panel 1 through a hinge and is matched with the inner recess 32, so that the anti-collision block 31 can be rotated. When the anti-collision block 31 works, the lower surface thereof is flush with the lower surface of the desktop panel 1. When the anti-collision block 31 does not work, the upper surface thereof is flush with the upper surface of the desktop panel 1.
[0033] In the embodiment, the inner recess 32 provides space for the rotation of the anti-collision block 31 and provides installation control for the guiding mechanism 4; the inner part of the anti-collision block 31 is provided with a guiding groove 33 for matching the guiding mechanism.
[0034] In the embodiment, the anti-collision block 31 has a three-layer structure, the outermost layer is a silica gel layer 35, the middle layer is a sponge layer 36, and the innermost layer is a support 37. Through the characteristics of the materials on the two outer sides, the buffering effect during impact can be further increased, and the safety can be greatly improved.
[0035] In the embodiment, the guiding mechanism 4 comprises a guiding rod 41 and a pressure spring 42, wherein the guiding rod 41 is fixed on the side wall of the desktop panel 1 and is in a circular arc shape, and is matched with the hinge to make the rotation of the anti-collision device 3 more stable. It should be noted that the guiding rod 41 is matched with the guiding groove 33, and the guiding rod 41 can completely enter the guiding groove 33.
[0036] In this embodiment, the compression spring 42 is sleeved outside the guide rod 41, and one end of the compression spring 42 is attached to the side wall of the tabletop panel 1, and the other end of the compression spring 42 is attached to the inner recess 32. When the guide rod 41 enters the guide groove 33, the compression spring 42 is compressed at this time, and the anti-collision device 3 is stationary due to the action of the lock block 34. When the lock block 34 is opened, the compression spring 42 resets and pops out the anti-collision device 3, achieving the protection effect.
[0037] Further, the maximum angle is adjusted by the hinge, so that the guide rod 41 will always have a part in the guide groove 33, and the device runs more smoothly and is not easy to jam.
[0038] In this embodiment, after the anti-collision device 3 is popped out, it is supported by the compression spring 42, and since the compression spring 42 itself can be compressed, when it receives an impact, it will be compressed, that is, the anti-collision device 3 will also rotate downward, and in this process, the buffering effect will be further increased, reducing the damage of the collision.
[0039] Further, when the anti-collision device 3 is in operation, the upper surface thereof is inclined to form an inclination angle towards the outside and downward, so that when a collision occurs, there will be a downward component force to compress the compression spring 42, thereby achieving the effect of increasing the buffering, and cooperating with the material of the anti-collision block 31, the safety can be greatly improved.
[0040] As shown in Figure 1 Figure 2 and Figure 6 When the anti-collision device 3 is not in operation, the surface thereof is flush with the tabletop panel 1 and wrapped outside the lower side of the side wall of the tabletop panel 1, without affecting the overall neatness and beauty; when the anti-collision device 3 is in operation, the anti-collision device 3 is rotated and popped out, wrapped outside the upper side of the side wall of the tabletop panel 1, reducing the damage of the collision.
[0041] As shown in Figure 3 and Figure 4 The lock block 34 adopts a car trunk lock, which is not present in the prior art. The lock block 34 includes a lock body and a hook ring. The lock body is located inside the anti-collision device 3, and the hook ring is located on the lower surface of the tabletop panel 1. When the anti-collision device 3 is not in operation, the lock body is clamped with the hook ring, that is, the anti-collision device 3 is fixed by the lock block 34.
[0042] Further, the automobile trunk lock usually has two unlocking modes, one is motor unlocking, and the other is pull rope unlocking, so the lock block 34 can also be opened in two ways, one is that the distance measuring sensor 21 detects, and when it is detected that the distance from the person is less than the safety threshold, a signal is sent, and the motor in the lock body works to control the lock block 34 to open through the motor unlocking mode; the other is that the control button of the pull rope unlocking is integrated into the control switch 5, and the lock block 34 on both sides is controlled through the buttons on the control switch 5 to realize the opening of the lock block 34.
[0043] In the embodiment, the distance measuring sensor 21 for detecting distance is installed on the table leg 2 on both sides, which is an infrared sensor in the embodiment and belongs to the prior art. When it is detected that the distance from the person is greater than or equal to the safety threshold, there is no collision risk at present, and the anti-collision device does not enter the working state; and when it is detected that the distance from the person is less than the safety threshold, it indicates that there is a collision risk, and the lock block 34 of the anti-collision device 3 is opened through the motor unlocking mode, the anti-collision device 3 is popped out to enter the working state, and the collision consequence is reduced.
[0044] Further, whether the anti-collision device 3 is in working or not, the distance measuring sensor 21 will not be blocked and can always be in normal working state.
[0045] In the embodiment, before use, the anti-collision device 3 on both sides can be directly started through the control switch 5, the lock block 34 is opened through the pull-up unlocking mode, the anti-collision device 3 is popped out and wrapped on the side walls of the desktop panel 1 on both sides, and the anti-collision device 3 is always in working state, so that the leaning distance measuring sensor 21 does not trigger the anti-collision device 3, and the safety hidden danger is reduced.
[0046] Further, when it is not needed to use, the anti-collision device 3 needs to be retracted, only the anti-collision block 31 is pressed downward to rotate 90 degrees, and the lock body of the lock block 34 is clamped with the hook, so that the surface of the learning desk is clean and flat, and the appearance is not affected.
[0047] The use method of the child learning desk with anti-collision function in the embodiment is as follows:
[0048] The height of the table leg 2 is adjusted through the control switch 5, so that the learning desk is at a suitable height for normal use. When the distance measuring sensor 21 detects that a person approaches, and the distance from the person is less than the safety threshold at this time, it indicates that there is a collision risk, the lock block 34 is opened, the pressure spring 42 is reset, the anti-collision device 3 is popped out, and it is rotated 90 degrees to wrap outside the desktop panel 1, so as to reduce the collision damage.
[0049] When the collision occurs, the outer two layers of the anti-collision block 31 can increase the buffer, and the collision can also make the anti-collision block 31 shrink downward along the guide rod 41, at this time, the pressure spring 42 is compressed, and further plays a buffering role, and the two cooperate, so that the damage during the collision can be greatly reduced, and the safety can be improved.
[0050] When it is not needed, only need to press the anti-collision block 31 downward, make it rotate around the hinge point, until the anti-collision block 31 is fixed through the lock block 34, of course, also can be in the beginning of the study desk is put into use, through the control switch 5 control anti-collision device 3 pops out, in this way, can avoid because of the failure causes the anti-collision device 3 to be unable to normally trigger and work.
[0051] The above examples are only for illustrating the technical idea of the present application, and cannot limit the protection scope of the present application, and any modification made on the basis of the technical scheme according to the technical idea of the present application falls within the protection scope of the present application.
