Description

Technical Field

[0001] The invention belongs to the field of pedestrian passive safety, and in particular relates to a human leg traffic injury protection device. Background Art

[0002] Since pedestrians are directly exposed to various traffic environments and often suffer the most serious injuries in car traffic accidents, strengthening safety measures to protect vulnerable pedestrians has become a research focus.

[0003] In a collision accident, the femur, tibia and knee are the most vulnerable parts of the pedestrian's lower limb structure. The femur and tibia are the main components of the lower limb support structure, while the knee joint has a complex internal structure, with multiple ligaments intertwined in the joint cavity, connecting bones and muscles. The loss of function of the above parts will seriously affect a person's standing and walking functions.

[0004] The force generated by the collision acts on the skin, muscles, ligaments, bones and other parts. Once the force on the corresponding parts exceeds the limit, it will cause fractures, ligament ruptures, muscle injuries and other injuries. When the bending moment generated by the collision causes the stress on the leg bones to exceed the strength limit of the femur and tibia, fractures will occur. Existing protective devices usually protect the leg bones in a fixed support manner. Full coverage protection is too heavy and inconvenient to walk, while intermittent protection cannot automatically adjust the protection position, cannot adapt well to people of different heights and leg lengths, and has poor ability to cope with different protection scenarios.

[0005] Based on this, the applicant considered designing a traffic injury protection device for human legs. Summary of the invention

[0006] In view of the above problems, the present invention provides a human leg traffic injury protection device that overcomes the above problems or at least partially solves the above problems. The technical solution is as follows:

[0007] The human leg traffic injury protection device comprises a first vertical guard plate, a second vertical guard plate, a first cross guard plate and a second cross guard plate, the first vertical guard plate and the second vertical guard plate are vertically and relatively arranged, a guarding gap is formed between the first vertical guard plate and the second vertical guard plate, a positioning plate is mutually connected at the bottom of the first vertical guard plate and the bottom of the second vertical guard plate, a first transmission mechanism is installed on the first vertical guard plate, the first cross guard plate is slidably arranged on the first vertical guard plate and is transmission-connected with the first transmission mechanism, the first cross guard plate spans the guarding gap to the second vertical guard plate, the first transmission mechanism is used to drive the first cross guard plate to move up and down, the second transmission mechanism is installed on the second vertical guard plate, the second cross guard plate is slidably arranged on the second vertical guard plate and is transmission-connected with the second transmission mechanism, the first cross guard plate spans the guarding gap to the first vertical guard plate, the second transmission mechanism is used to drive the second cross guard plate to move up and down, and clamping arms are arranged on the bottoms of the two opposite outer sides of the first vertical guard plate and the second vertical guard plate.

[0008] Compared with the prior art, the human leg traffic injury protection device of the present invention has the following advantages:

[0009] By setting the first vertical guard plate, the second vertical guard plate, the first transverse guard plate, the second transverse guard plate, the first transmission mechanism and the second transmission mechanism, the positions of the first transverse guard plate and the second transverse guard plate on the first vertical guard plate and the second vertical guard plate respectively can be adjusted, so that the positions of the first transverse guard plate and the second transverse guard plate can be adjusted to adapt to people of different heights and leg lengths while reducing the carrying weight, and the protection position can also be adjusted according to the needs of different protection scenes, with better adaptability. At the same time, the positions of the first transverse guard plate and the second transverse guard plate can also be adjusted in a targeted manner according to the location of scars on the wearer's legs to reduce the chance of secondary injury.

[0028] Compared with the prior art, the human leg traffic injury protection device of the present invention has the following advantages:

[0029] By setting the first vertical guard plate 100, the second vertical guard plate 200, the first transverse guard plate 110, the second transverse guard plate 210, the first transmission mechanism and the second transmission mechanism, the positions of the first transverse guard plate 110 and the second transverse guard plate 210 on the first vertical guard plate 100 and the second vertical guard plate 200 respectively can be adjusted. While reducing the carrying weight, the positions of the first transverse guard plate 110 and the second transverse guard plate 210 can be adjusted to adapt to people of different heights and leg lengths, and the protection position can also be adjusted according to the needs of different protection scenes, with better adaptability. At the same time, the positions of the first transverse guard plate 110 and the second transverse guard plate 210 can also be specifically adjusted according to the location of scars on the wearer's legs to reduce the chance of secondary injury.

[0030] The above-mentioned human leg traffic injury protection device has the advantages of simple structure and easy implementation, and the cost of use is low, which can improve the benefits.

[0031] In this embodiment, Figure 1-6As shown, the first transmission mechanism includes a first motor 410 and a first transmission shaft 420, the first motor 410 is installed at the inner bottom of the first vertical guard plate 100, a first sliding track 430 is vertically opened on the outer wall of the first vertical guard plate 100, the first transmission shaft 420 is vertically installed in the first sliding track 430, and is coaxially connected to the rotating shaft of the first motor 410, a first transmission block 440 is arranged on the inner wall of the first horizontal guard plate 110, a screw hole penetrating from top to bottom is arranged in the first transmission block 440, and the first transmission block 440 is threadedly matched with the first transmission shaft 420.

[0032] In this way, by setting the first motor 410 and the first transmission shaft 420, the first transverse guard plate 110 can be driven by the first transmission shaft 420 to move up and down along the first vertical guard plate 100, so as to automatically adjust the position of the first transverse guard plate 110, and the transmission structure is relatively simple.

[0033] In this embodiment, Figure 1-6 As shown, the second transmission mechanism includes a second motor 510 and a second transmission shaft 520, the second motor 510 is installed at the inner bottom of the second vertical guard plate 200, a second sliding track 530 is vertically opened on the outer wall of the second vertical guard plate 200, the second transmission shaft 520 is vertically installed in the second sliding track 530, and is coaxially connected to the rotating shaft of the second motor 510, a second transmission block 540 is arranged on the inner wall of the second horizontal guard plate 210, and a screw hole penetrating from top to bottom is also arranged in the second transmission block 540, and the second transmission block 540 is threadedly matched with the second transmission shaft 520.

[0034] In this way, by setting up the second motor 510 and the second transmission shaft 520, the second transverse guard plate 210 can be driven by the second transmission shaft 520 to move up and down along the second vertical guard plate 200 to automatically adjust the position of the second transverse guard plate 210, and the transmission structure is relatively simple.

[0035] In this embodiment, Figure 1-6 As shown, an insertion and protection mechanism is provided between the middle to the bottom of the first vertical guard plate 100 and the second vertical guard plate 200 , and the insertion and protection mechanism is used to supplement the remaining space in the guard gap 300 .

[0036] In this way, through the provision of the insertion protection mechanism, the position between the first vertical guard plate 100 and the second vertical guard plate 200 that is not protected by the first horizontal guard plate 110 and the second horizontal guard plate 210 can be filled by the insertion protection mechanism, so as to flexibly select and adjust the protection strategy and protection position.

[0037] In this embodiment, Figure 1-6As shown, the plug-in protection mechanism includes a plug-in rail 610 and a plug-in protection plate 620. There are two plug-in rails 610, which are respectively arranged on the two opposite inner sides of the first vertical guard plate 100 and the second vertical guard plate 200, and the extension directions of the two plug-in rails 610 are respectively the same as the length directions of the corresponding first vertical guard plate 100 and the second vertical guard plate 200. The plug-in protection plate 620 is arranged between the two plug-in rails 610, and the two ends of the plug-in protection plate 620 are respectively inserted in the two plug-in rails 610.

[0038] In this way, by setting the plug-in rail 610 and the plug-in plate 620, the plug-in plate 620 can be plugged into the plug-in rail 610, and the plug-in rail 610 can support the plug-in plate 620 to arbitrarily select a plug-in position, thereby achieving stepless adjustment, and the position adjustment better meets the needs.

[0039] In this embodiment, Figure 1-6 As shown, the protection plate 620 includes a first plug-in end 621 and a second plug-in end 622 opposite to each other, and the outer surfaces of the first plug-in end 621 and the second plug-in end 622 are coated with an elastic film layer. The protection plate 620 is respectively plugged into the two plug-in rails 610 through the first plug-in end 621 and the second plug-in end 622.

[0040] In this way, by setting the first plug-in end 621, the second plug-in end 622 and the elastic film layer, the plug-in plate 620 can be inserted into the plug-in track 610 and can be squeezed by the elastic film layer and the inner wall of the plug-in track 610 to generate a certain friction force so that the plug-in plate 620 is fixed on the plug-in track 610.

[0046] During implementation, a hinge return spring is provided on the hinge of the clamp arm 700 to automatically return the clamp arm 700 to its original position.

[0047] In this embodiment, Figure 1-6 As shown, the cross sections of the first vertical guard plate 100 , the second vertical guard plate 200 , the first horizontal guard plate 110 and the second horizontal guard plate 210 are all arc-shaped.

[0048] In this way, by setting the cross-sections of the first vertical guard plate 100, the second vertical guard plate 200, the first horizontal guard plate 110 and the second horizontal guard plate 210 to be arc-shaped, the cross-sections can be better adapted to the leg shape of the human body.

[0049] In this embodiment, Figure 1-6 As shown, a binding strap 800 is provided on the middle portions of the opposite outer sides of the first vertical guard plate 100 and the second vertical guard plate 200 .

[0050] In this way, by setting the strap 800, the strap 800 can cooperate with the clamp arm 700 at the same time to achieve double binding for better wearing.

[0051] The above are only preferred implementations of the present invention. It should be pointed out that a number of modifications and improved technical solutions made by those skilled in the art without departing from the technical solution should also be deemed to fall within the scope of protection required by the claims.
