[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figures 1 to 3 As shown, the utility model provides an auxiliary structure of a mobile DVD player, comprising a DVD player body 1, a heat dissipation hole 2 and a display panel 3, characterized in that: the display panel 3 is movably connected to the top of the DVD player body 1 through a hinge, the heat dissipation hole 2 is opened at the bottom of the DVD player body 1, a plurality of heat dissipation holes 2 are provided and are distributed in a rectangular shape with equal distances, a lifting rod 4 is provided at the bottom of the DVD player body 1, four lifting rods 4 are provided and are distributed at the four corners of the bottom of the DVD player body 1, and a flipping and retracting mechanism 5 is fixedly connected to the top of the lifting rod 4.

[0023] refer to Figure 3The flipping and retracting mechanism 5 includes a flipping block 51, which is fixedly connected to the top of the lifting rod 4. A rotating rod 52 is fixedly connected inside the flipping block 51. The front and rear sides of the rotating rod 52 are movably connected to a supporting block 53. The inner side of the supporting block 53 is fixedly connected to the DVD player body 1, and a locking component 54 is provided on the outer side of the supporting block 53.

[0024] As a technical optimization solution of the utility model, by setting a flipping and retracting mechanism 5, when the operator needs to retract the lifting rod 4, the locking assembly 54 is unlocked, and then the operator twists the rotating rod 52 to rotate the rotating rod 52 through the supporting block 53, and then the rotating rod 52 drives the flipping block 51 to rotate, so that the flipping block 51 drives the lifting rod 4 to rotate and retract, thereby preventing the lifting rod 4 from unfolding and affecting the operator's storage.

[0025] refer to Figure 3 The locking assembly 54 includes a locking screw hole 541 , which is opened on the outer side of the support block 53 , and a locking screw 542 is threadedly connected to the inner side of the locking screw hole 541 .

[0026] As a technical optimization scheme of the utility model, by setting a locking assembly 54, when the rotating rod 52 rotates to drive the flip block 51 and the lifting rod 4 to be retracted or unfolded, the operator screws the locking screw 542 into the interior of the locking screw hole 541, and the operator tightens the locking screw 542, so that the locking screw 542 can firmly resist the rotating rod 52, thereby preventing the rotating rod 52 from rotating after the lifting rod 4 is retracted or unfolded, thereby ensuring the stability of the use of the lifting rod 4.

[0027] refer to Figure 3 The bottom of the lifting rod 4 is fixedly connected with a stabilizing plate 6 , and the stabilizing plate 6 is used in conjunction with the lifting rod 4 .

[0028] As a technical optimization solution of the utility model, by setting a stabilizing plate 6, the stabilizing plate 6 is fixedly installed at the bottom of the lifting rod 4, so that the stabilizing plate 6 can increase the contact area between the lifting rod 4 and the ground, so that the lifting rod 4 can be more stable when in contact with the ground for support.

[0029] refer to Figure 3 The front end and the rear end of the rotating rod 52 are fixedly connected with a truncated cone block 7, and the diameter of the truncated cone block 7 is larger than the diameter of the rotating rod 52.

[0030] As a technical optimization solution of the utility model, the truncated cone block 7 is provided so that the truncated cone block 7 and the rotating rod 52 are fixedly installed, so that the truncated cone block 7 can limit the rotation of the rotating rod 52 and prevent the rotating rod 52 from being separated from the supporting block 53.

[0031] refer to Figure 3 The outer end of the locking screw 542 is fixedly connected with a twisting block 8, and the twisting block 8 is butterfly-shaped.

[0032] As a technical optimization solution of the utility model, by adopting a butterfly-shaped twisting block 8, the twisting block 8 can increase the contact area between the operator's hand and the locking screw 542, so that the operator can save more effort when using the locking screw 542 through the twisting block 8.

[0033] refer to Figure 3 A non-slip pad 9 is pasted on the bottom of the stabilizing plate 6, and the material of the non-slip pad 9 is natural rubber.

[0034] As a technical optimization solution of the utility model, by providing an anti-skid pad 9, when placed on a smooth platform, the anti-skid pad 9 can increase the friction between the stabilizing plate 6 and the ground, thereby preventing the device from sliding randomly due to the platform being too smooth.

[0035] The working principle and use process of the utility model are as follows: when the operator needs to use the DVD player body 1 to watch, at this time, the lifting rod 4 is in the retracted state, and the operator loosens the locking screw 542 so that the locking screw 542 no longer presses against the rotating rod 52, and then the operator turns the rotating rod 52, and then the rotating rod 52 drives the flip block 51, the lifting rod 4 and the stable plate 6 to flip downward, so that the stable plate 6 and the lifting rod 4 can lift up the DVD player body 1, ensuring the heat dissipation effect, and then the operator tightens the locking screw 542 to make the locking screw 542 firmly The rotating rod 52 is firmly held against the rotating rod 52 to prevent the rotating rod 52 from rotating at will. When the operator is not using the DVD player body 1 and needs to store it, the operator loosens the fixed locking screw 542 again, and then the operator twists the rotating rod 52 to make the rotating rod 52 rotate through the supporting block 53, and then the rotating rod 52 drives the flip block 51 to rotate, so that the flip block 51 drives the lifting rod 4 to rotate and retract, thereby preventing the lifting rod 4 from unfolding and affecting the operator's storage. After the retraction is completed, the locking screw 542 needs to be tightened again to prevent the rotating rod 52 from rotating.

[0036] To sum up: this auxiliary structure of a mobile DVD player, by setting a lifting rod 4, enables the lifting rod 4 to lift up the DVD player body 1, thereby ensuring the normal heat dissipation of the heat dissipation holes 2 at the bottom of the DVD player body 1, and at the same time, the flip recovery mechanism can retract the lifting rod 4 when the lifting rod 4 is not needed, thereby preventing the lifting rod 4 from affecting the storage of the DVD player body 1, thereby solving the problem that in actual applications, the mobile DVD player adopts a bottom heat dissipation design to maintain a stable playback effect, but due to the lack of an auxiliary structure to properly lift the device, when the device is placed on a platform such as a desktop, its heat dissipation holes are easily blocked, thereby seriously hindering the heat dissipation effect.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
