DETAILED DESCRIPTION

[0023] See also Figure 1-5 , the embodiments of the utility model are further described;

[0024] A vehicle backup power supply protection device comprises a box body;

[0025] The box body includes a base 1, a rotating ring 2 and a top cover 3. A mounting seat 5 for mounting a power supply is fixed on the inner wall of the base 1. The top cover 3 is located above the base 1. The rotating ring 2 is rotatably connected between the base 1 and the top cover 3.

[0026] The top of the top cover 3 is embedded with a heat dissipation cover 4 through an opening, and the top cover 3 is provided with a plurality of limit grooves 8, and the heat dissipation cover 4 is provided with a plurality of screw holes respectively connected with the plurality of limit grooves 8, and a plurality of quick-release parts are arranged between the heat dissipation cover 4 and the top cover 3, and the lower end of the quick-release part is limited in the limit groove 8, and the upper end is threadedly connected in the limit groove 8;

[0027] In this scheme, if Figure 2 , 3 As shown in Figure 5, if the user wants to place the vehicle backup power supply in the box, twist the quick release piece upwards so that the upper end of the quick release piece is screwed out of the screw hole, and then pinch the quick release piece and rotate it 90 degrees so that the lower end of the quick release piece is no longer restricted by the limiting groove 8. Then pull the quick release piece upwards to move its lower end out of the limiting groove 8. At the same time, the heat dissipation cover 4 is opened from the top cover 3. At this time, there is a through hole on the top cover 3. The user can embed the power supply through the through hole into the mounting seat 5. At this time, the power supply is positioned in the box. Finally, the heat dissipation cover 4 can be re-covered on the top cover 3 in the reverse order of the above operations. When the power supply needs to be replaced, the old power supply can be quickly replaced by following the above operations. The power supply installation and removal operations are simple, and the power supply can be quickly installed and removed without the use of tools.

[0028] When the rotating ring 2 on the box containing the power supply is hit by a foreign object, the rotating ring 2 will drive the top cover 3 to rotate on the base 1, so that the impact force is converted into the power for the rotating ring 2 to rotate, thereby greatly reducing the impact force and protecting the power supply in the box.

[0029] Similarly, when the top cover 3 on the box containing the power supply is hit by a foreign object, the top cover 3 will rotate on the rotating ring 2 due to the impact force, and the rotating ring 2 will rotate on the base 1 after being subjected to the force, so that the impact force is greatly reduced and the power supply in the box can be well protected.

[0030] When the power supply is in use, heat is generated, and the heat can be discharged to the outside of the box through the heat dissipation cover 4 to prevent heat accumulation inside the box and affect the normal use of the power supply.

[0031] The lower section of the interior of the limiting groove 8 is circular, and the upper section of the interior is square;

[0032] The quick release part includes a limit block 7 and a threaded rod 9. The upper end of the limit block 7 is provided with a threaded groove 10. The lower end of the threaded rod 9 is threadedly connected in the threaded groove 10. The limit block 7 is T-shaped, and the limit block 7 extends into the limit groove 8 through the screw hole. The upper outer portion of the threaded rod 9 is threadedly connected in the screw hole.

[0033] In this scheme, if Figure 3 and 5 As shown, when the quick-release parts need to be disassembled, the threaded rod 9 is rotated upward, and the upper end of the threaded rod 9 will gradually be screwed out of the screw hole, and the lower end will be rotated upward in the thread groove 10. It should be noted that the groove depth of the thread groove 10 is greater than the hole depth of the screw hole. After the upper end of the threaded rod 9 is screwed out of the screw hole, its lower end is still in the thread groove 10, so as to ensure that the threaded rod 9 can drive the limit block 7 to rotate and move in the later stage. Then, the threaded rod 9 is pinched and rotated 90 degrees to align the lower end of the T-shaped limit block 7 with the upper part of the limit groove 8, and the restriction of the lower end of the limit block 7 by the lower part of the limit groove 8 is released. Then, the threaded rod 9 is pulled upward to drive the limit block 7 to move out of the limit groove 8, and the heat dissipation cover 4 is opened from the top cover 3, and the user can install the power supply in the mounting seat 5 in the box body. Finally, the heat dissipation cover 4 can be re-covered on the top cover 3 according to the reverse order of the above operations. When the power supply needs to be replaced, the old power supply can be quickly replaced by following the above operations. The power supply can be installed and removed easily without the use of tools.

[0034] A circle of slide grooves 19 are formed on both the upper and lower sides of the rotating ring 2, and at least one annular slide groove 14 is formed on the inner wall of the slide groove 19. Slip rings 11 are fixed to the top of the base 1 and the bottom of the top cover 3. The two slip rings 11 are slidably connected to the two slide grooves 19, and at least one L-shaped slider 15 slidably connected to the slide groove 14 is fixed to the slip rings 11.

[0035] In this solution, when the rotating ring 2 rotates, the slip ring 11 at the top of the base 1 and the bottom of the top cover 3 will slide in the slide groove 2 19 on the upper and lower sides of the rotating ring 2 respectively, and at the same time, the L-shaped slider 15 on the slip ring 11 will slide in the slide groove 14 where it is located. The setting of the slide groove 14 and the L-shaped slider 15 is to limit the slip ring 11, which is conducive to the stable sliding of the slip ring 11 in the slide groove 2 19.

[0036] A plurality of spring shafts 13 are fixed on the slip ring 11, and a sliding sheet 12 slidably connected to a second adjacent sliding groove 19 is fixed at the end of each spring shaft 13;

[0037] In this solution, when the rotating ring 2 is subjected to an impact force, the impact force can be decomposed into a horizontal component and a longitudinal component. The horizontal component can cause the rotating ring 2 to drive the top cover 3 to rotate, converting the impact force into the power for the rotating ring 2 to rotate. At the same time, the rotating ring 2 and the top cover 3 will also be affected by the longitudinal component and move longitudinally. The slip ring 11 will compress or stretch the spring shaft 13 thereon. Since the spring shaft 13 has elastic force, the impact force can be consumed to achieve the purpose of reducing the impact force. It should be noted that there is enough space between the L-shaped slider 15 and the slide groove 14 for the L-shaped slider 15 to move longitudinally. Similarly, when the top cover 3 is subjected to an impact force, the top cover 3 will rotate on the rotating ring 2, and the top cover 3 will move slightly longitudinally to compress and stretch the spring shaft 13, so that the impact force is consumed, thereby greatly reducing the impact force, and the power supply in the box can be well protected. When the sliding sheet 12 contacts the slide groove 2 19, it will slide inside it.

[0038] The L-shaped sliders 15 are sleeved with buffer sleeves 16 on the outside;

[0039] In this solution, the buffer sleeve 16 is provided to prevent the L-shaped slider 15 from directly hitting the slide groove 14. The buffer sleeve 16 is elastic and will undergo elastic deformation when hitting the slide groove 14, which can effectively buffer the impact force.

[0040] A heat dissipation net 17 is fixed to the inner wall of the heat dissipation cover 4, and a plurality of heat dissipation holes 18 communicating with the heat dissipation net 17 are opened on the surface of the heat dissipation cover 4, and a mounting hole 6 for installing the socket is opened in the center of the surface of the heat dissipation cover 4;

[0041] In this solution, the heat inside the box will first pass through the heat dissipation net 17 and then be discharged through the heat dissipation holes 18. The heat dissipation net 17 is arranged on the inner wall of the heat dissipation cover 4 to protect the heat dissipation net 17. It should be noted that the socket is fixed on the power supply and electrically connected to the power supply. By plugging the power connection line between the socket and the power supply of the car, the power supply in the box can be used to power the car. Since the mounting hole 6 is located in the center of the surface of the heat dissipation cover 4, it does not affect the rotation of the top cover 3 and the heat dissipation cover 4.
