Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 The present invention provides an embodiment of a drop-proof children's tablet computer, comprising a tablet computer 1 and a drop-proof buffer device 2. The tablet computer 1 is snapped onto the inner front end of the drop-proof buffer device 2. The drop-proof buffer device 2 includes a main support frame 3, corner protectors 5, and a bottom buffer assembly 6. Spring rubber plates 4 are evenly fixedly connected to the rear side of the main support frame 3 to protect the rear end of the tablet computer 1. The corner protectors 5 are symmetrically arranged at the four corners of the main support frame 3, and the bottom buffer assembly 6 is symmetrically arranged at the rear end of the main support frame 3.

[0023] The corner protector assembly 5 includes a built-in corner protector 7. The bottom end of the built-in corner protector 7 has a limiting slot 8. The four corners of the tablet computer 1 are engaged with the inner side of the limiting slot 8. When the tablet computer 1 is dropped, the four corners are most vulnerable to impact. The limiting slot 8 secures the four corners of the tablet computer 1 to the inner side of the built-in corner protector 7 for protection. An outer corner protector 9 is fixedly connected to the outer side of the built-in corner protector 7. A cavity 10 is provided between the built-in corner protector 7 and the outer corner protector 9. The built-in corner protector 7 is made of hard plastic, and the outer corner protector 9 is made of soft plastic. The cavity 10 increases the buffer space between the built-in corner protector 7 and the outer corner protector 9. First springs 12 are evenly distributed inside the cavity 10. Buffer rubber posts 11 are fixedly connected to both ends of the first springs 12. The buffer rubber pillars 11 are fixedly connected to the inner end of the outer corner protector 9 and the outer end of the inner corner protector 7 respectively. The buffer rubber pillars 11 and the first spring 12 are located on the side of the cavity 10 near the front end of the main support frame 3. The tops of the buffer rubber pillars 11 and the first spring 12 are inclined towards the front end of the main support frame 3. When the first spring 12 is compressed, it contracts to absorb the impact force. When the first spring 12 rebounds and releases its elastic potential energy, it compresses the buffer rubber pillars 11. The buffer rubber pillars 11 undergo viscoelastic deformation under compression, converting some of the kinetic energy into internal energy, thereby reducing the peak stress of the first spring 12 and thus achieving the buffering effect. The first spring 12 is located inside the cavity 10 near the front end, thereby strengthening the drop protection of the front end of the tablet computer 1.

[0024] The bottom buffer assembly 6 includes an impact-resistant rubber plate 13. Rubber connecting plates 14 are fixedly connected to both ends of the impact-resistant rubber plate 13 near the side of the main support frame 3. Vertical hollow columns 15 are uniformly fixedly connected to the side of the impact-resistant rubber plate 13 near the rubber connecting plates 14. A diagonal hollow column 17 is fixedly connected to one side of the vertical hollow column 15. A second spring 16 is fixedly installed on the inner side of the vertical hollow column 15, and a third spring 18 is fixedly installed on the inner side of the diagonal hollow column 17. The impact force is absorbed by the built-in second spring 16 and third spring 18, and the elastic potential energy is transferred to the vertical hollow column 15 and the diagonal hollow column 17 by the amplitude of the contraction and rebound, and is converted into heat energy by the vertical hollow column 15 and the diagonal hollow column 17.

[0025] The ends of the rubber connecting plate 14 and the vertical hollow column 15 away from the impact-resistant rubber plate 13 are respectively fixedly connected to the rear end of the main support frame 3. One end of the diagonal hollow column 17 is fixedly connected to the impact-resistant rubber plate 13, and the other end of the diagonal hollow column 17 is fixedly connected to the rear end of the main support frame 3. The end of the diagonal hollow column 17 near the main support frame 3 is designed to be inclined towards the middle of the main support frame 3. The inclined design of the diagonal hollow column 17 increases the impact resistance of the rear end of the anti-fall buffer device 2. The diagonal hollow column 17 provides support for side falls.

[0026] Working principle: During use, when the tablet computer 1 is accidentally dropped and lands on a corner, the ground impacts the outer corner protector 9. At this moment, the outer corner protector 9 deforms and compresses the buffer rubber column 11 and the first spring 12. The contraction of the buffer rubber column 11 and the first spring 12 absorbs the impact force, reducing the impact on the inner corner protector 7. After absorbing the impact force, the first spring 12 releases its elastic potential energy and rebounds, compressing the buffer rubber column 11. The buffer rubber column 11 undergoes viscoelastic deformation under compression, converting some of its kinetic energy into internal energy, thus reducing the peak stress of the first spring 12, thereby achieving a cushioning effect. When the angle of the drop is tilted towards the front of the tablet computer 1, the tablet computer... All four corners of the tablet computer 1 are protected by corner protector components 5. When the angle of the fall is tilted towards the rear of the tablet computer 1, the first spring 12 pushes the outer corner protector 9 upward when it rebounds. The first spring 12 is located near the front end of the cavity 10. Therefore, the rebound of the first spring 12 pushes the tablet computer 1 to tilt backward. When the impact-resistant rubber plate 13 contacts the ground, it compresses the vertical hollow column 15 and the diagonal hollow column 17 to contract. At the same time, it compresses the second spring 16 and the third spring 18 to contract and absorb the impact force. The elastic potential energy generated by the contraction and rebound of the second spring 16 and the third spring 18 is converted into heat energy by the vertical hollow column 15 and the diagonal hollow column 17, thereby achieving the function of cushioning and anti-fall.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
