[0029] like Figure 1-Figure 3 As shown, this embodiment provides a flippable protective device, including a tail frame 10, a protective bar 20, a driving member 30 and a locking member 40; the protective bar 20 is rotatably arranged on the tail frame 10, the driving member 30 is used to drive the protective bar 20 to rotate relative to the tail frame 10, the locking member 40 is arranged on the protective bar 20, and the tail frame 10 is provided with a first hole position 11 and a second hole position 12. When the protective bar 20 rotates relative to the tail frame 10, the locking member 40 is inserted into the first hole position 11 or the second hole position 12 to fix the protective bar 20 at the first position or the second position.
[0030] Specifically, one end of the driving member 30 is connected to the tail frame 10, and the other end is connected to the protective bar 20. The driving member 30 can be hydraulically driven or motor driven, depending on the specific situation; in addition, the first position is the extended state of the protective bar 20, and the second position is the retracted state of the protective bar 20.
[0031] It can be understood that in this embodiment, when the vehicle is traveling on an urban road, in order to protect the life safety of the occupants of the rear-end vehicle, the protective bar 20 is unfolded so that the locking piece 40 is inserted into the first hole 11, and the protective bar 20 is fixed in the first position; when the vehicle is traveling on a forest road, in order to avoid damage to the vehicle and slow driving due to the unevenness of the forest road and the entanglement of various vines, the protective bar 20 is retracted, and the locking piece 40 is removed at this time, and then the protective bar 20 is rotated until the protective bar 20 reaches the second position, that is, when the protective bar 20 is attached to the rear end of the vehicle, the locking piece 40 is inserted into the second hole 12, so that the protective bar 20 fixes the rear protection device in the second position; the utility model can be used to ensure the passability in both urban and forest conditions, and can independently and easily realize the rotation of the rear protection to meet different usage conditions.
[0032] In a preferred embodiment, the protection bar 20 includes a gear lever 21 and a connecting rod 22, wherein the connecting rod 22 is vertically connected to the gear lever 21, and the connecting rod 22 is rotatably connected to the tail frame 10. It is understandable that the connecting rod 22 is connected to the gear lever 21 by welding, and in order to make the gear lever 21 more stable, multiple connecting rods 22 are connected to the gear lever 21, and then the multiple connecting rods 22 are articulated to the tail frame 10.
[0033] It is understandable that the shift rod 21 and the connecting rod 22 are made of alloy steel with relatively high hardness, or ordinary steel with low price can be used.
[0034] In a preferred embodiment, the locking member 40 includes a sleeve 41, a locking pin 42 and a wrench 43; a through mounting hole is provided on the connecting rod 22, the sleeve 41 is provided on the mounting hole, a mounting groove 421 is provided on the end face of the mounting hole, the locking pin 42 is movably provided in the mounting groove 421, the wrench 43 is connected to one end of the locking pin 42 away from the mounting hole, and under the push of the wrench 43, the locking pin 42 can extend out of the mounting hole.
[0035] It can be understood that when using the locking piece 40 for locking, first lift the wrench 43 by hand, retract the locking pin 42 into the mounting groove 421, release the original lock of the locking piece 40, and then move the locking piece 40 to another hole position. After moving into place, press the wrench 43 by hand to insert the locking pin 42 from the mounting groove 421 into the hole position to achieve locking.
[0036] In a preferred embodiment, the flippable protection device further includes a connecting bolt 50 , which connects the tail frame 10 and the protection bar 20 , and the protection bar 20 uses the connecting bolt 50 as a rotation axis.
[0037] It is understandable that the function of the connecting bolt 50 is the same as that of the latch, and while connecting the two, the two can also rotate relative to each other. In order to prevent the tail rack 10 and the protection bar 20 from sliding off the latch, the connecting bolt 50 is used instead of the latch.
[0038] In a preferred embodiment, two stepped bushings 51 are further provided on the connecting bolt 50 , and the tail frame 10 and the protection bar 20 are arranged between the two stepped bushings 51 .
[0039] In detail, in order to reduce the friction between the connecting bolt 50 and the tail rack 10 and the protective bar 20, and to reduce the shortening of the service life due to friction damage, two stepped bushings 51 are provided on the connecting bolt 50. The tail rack 10 and the protective bar 20 are actually in contact with the stepped bushings 51 to reduce friction and facilitate rotation.
[0040] In a preferred embodiment, the flippable protective device also includes a first positioning structure, which includes a first blocking plate 13 and a first positioning plate 23. The first blocking plate 13 is arranged on the tail frame 10, and the first positioning plate 23 is arranged on the protective bar 20. When the first positioning plate 23 contacts the first blocking plate 13, the protective bar 20 is located in the first position.
[0041] In addition, the flippable protective device also includes a second positioning structure, which includes a second blocking plate 14 and a second positioning plate. The second blocking plate 14 is arranged on the tail frame 10, and the second positioning plate is arranged on the protective bar 20. When the second positioning plate contacts the second blocking plate 14, the protective bar 20 is located in the second position.
[0042] It is worth noting that the second positioning plate in this embodiment is actually the side wall of the connecting rod 22. When the protective bar 20 rotates to the second position, the side wall of the connecting rod 22 abuts against the second blocking plate 14 to prevent the protective bar 20 from further rotating.
[0043] In detail, the first positioning structure and the second positioning structure serve to facilitate the locking member 40 to find the first hole position 11 and the second hole position 12. It is not difficult to understand that if the first positioning structure and the second positioning structure are not set, it is difficult to control the locking member 40 to align with the hole positions when the protective bar 20 rotates relative to the tail frame 10, which will take too much time. Therefore, it is necessary to set the first positioning structure and the second positioning structure to facilitate the locking member 40 to quickly align with the hole positions.
[0044] In this embodiment, the driving member 30 is a gas spring. It can be understood that the gas spring has a simple structure, is cheap, does not take up space, and has a lifting force that meets the requirements.
[0045] In order to prevent the protection bar 20 from rusting, paint is sprayed on the protection bar 20 in this embodiment.
[0046] The reversible protective device provided in this embodiment has the following advantages:
[0047] In this embodiment, when the vehicle is traveling on an urban road, the protective bar 20 can be deployed to protect the lives of people in the rear-end vehicle. When the vehicle is traveling on a forest road, the protective bar 20 can be retracted to prevent the uneven forest road and various vines from causing damage to the vehicle and slow driving. The utility model can be used to ensure the passability in both urban and forest conditions, and can independently and easily realize the rotation of the rear guard to meet different usage conditions.
[0048] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
