Description

Technical Field

[0001] This utility model relates to the field of public transportation technology, specifically an energy-absorbing structure for transportation vehicle doors. Background Technology

[0002] As an important part of urban public transportation, buses operate in large numbers and for long periods of time on various routes, inevitably leading to collisions with other vehicles. In addition to seated passengers, buses also have a large number of standing passengers, making safety extremely important.

[0003] The current bus door structure mainly consists of a frame with a glass structure. In order to reduce weight and cost, the door frame structure is mostly hollow. Although the hollow cavity inside the door can absorb some impact force, it also reduces the mechanical strength of the overall frame. Without support inside the cavity, it is easy to bend or deform significantly when the impact force is too large. Utility Model Content

[0004] The purpose of this invention is to provide an energy-absorbing structure for transportation vehicle doors to solve the problems mentioned in the background art.

[0037] 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.

[0038] Please see Figure 1-4 In this embodiment of the utility model, a transportation vehicle door energy-absorbing structure includes an energy-absorbing door frame 1, a window structure 2, and an internal support structure 3. The energy-absorbing door frame 1 includes a door frame body 101. Corner reinforcement blocks 106 are fixedly installed at the four corners inside the frame rods of the door frame body 101. Several arched support rods 107 are arranged alternately and in opposite directions inside the frame rods of the door frame body 101. Connecting seats 108 are fixedly installed at both ends and the middle of the arched support rods 107. The window structure 2 is fixedly installed in the frame opening of the door frame body 101. The internal support structure 3 is fixedly installed on the upper and lower sides of the front surface of the door frame body 101.

[0039] Specifically, the entire device is installed at the bus door opening. The door frame body 101 serves as the supporting structure for the entire door, bearing the main external impact force. Corner reinforcement blocks 106 are fixedly installed at the four corners of the hollow part inside the door frame body 101 to enhance the ability of the four corners of the door frame body 101 to bear multi-directional stress. At the same time, multiple arched support rods 107 arranged in opposite directions are set inside the frame rod. The arched structure disperses the impact force in the front and rear directions, enhances the energy absorption effect of the hollow structure, and strengthens the mechanical strength of the hollow structure. Meanwhile, connecting seats 108 are set at both ends and the middle arched part of the arched support rods 107, which are directly connected to the hollow inner wall of the door frame body 101 to improve the kinetic energy transmission effect.

[0040] Example 1

[0041] like Figure 2 As shown, in this embodiment, the energy-absorbing door frame 1 also includes an upper hinge seat 103, a lower hinge seat 104, and a locking socket 105. The upper hinge seat 103 is fixedly installed on the upper edge of the front surface of the door frame body 101; the lower hinge seat 104 is fixedly installed on the bottom side of the door frame body 101; the locking socket 105 is fixedly installed on the middle of the other side of the door frame body 101; there are two door frame bodies 101, and the two door frame bodies 101 are connected to each other in the two-sided direction, and a sealing joint strip 102 is fixedly installed at the joint of the two door frame bodies 101.

[0042] In this embodiment, the upper hinge seat 103 and the lower hinge seat 104 are connected to the drive structures on the upper and lower sides of the bus door opening to control the opening and closing of the energy-absorbing door frames 1 on both sides. When the two sets of energy-absorbing door frames 1 are closed, the locking pins on both sides of the door opening are inserted into the locking socket 105 to lock the closed energy-absorbing door frames 1.

[0043] like Figure 3As shown, in this embodiment, the window structure 2 includes laminated glass 201, PVB interlayer 202, glass explosion-proof film 203, and aerogel interlayer 204. There are two sets of laminated glass 201, and the two sets of laminated glass 201 are fixedly installed at the front and rear openings of the frame opening of the door frame body 101, respectively. The PVB interlayer 202 is fixedly installed inside the laminated glass 201. The glass explosion-proof film 203 is fixedly attached to the outer surface of the laminated glass 201. The aerogel interlayer 204 is fixedly installed in the gap between the two sets of laminated glass 201.

[0044] In practice, most of the door is made of glass, with the entire glass structure consisting of two layers of double glass. The hollow interior is filled with an aerogel interlayer 204. The aerogel interlayer 204, a nanoporous material, provides a high specific surface area and dissipates energy through friction between liquid molecules and the pore surface, resulting in extremely high energy absorption efficiency. Meanwhile, the single glass layer uses a laminated glass 201 structure with an internal PVB interlayer 202. The PVB layer deforms to absorb energy, further improving the energy absorption effect. It also works in conjunction with the glass explosion-proof film 203 to adhere broken glass fragments together and prevent them from flying.

[0045] Example 2

[0046] Based on Embodiment 1, in order to compensate for the fact that the door body composed of the energy-absorbing door frame 1 and the window structure 2 in Embodiment 1 has a large area, when relying entirely on the energy absorption effect of the door body to resist impact, there is a situation where the door body bends from the middle under force.

[0047] like Figure 1 and 4 As shown, in this embodiment, the internal support structure 3 further includes a drive motor 301, a base rod 302, a support rod 303, a bidirectional lead screw 304, an internally threaded sleeve 305, a male connector 306, and a female connector 307. There are two support rods 303, and their rear ends are fixedly connected to the two side edges of the door frame body 101. The middle part of the base rod 302 is fixedly sleeved to the front end of the support rod 303. The drive motor 301 is fixedly installed on the base rod. In the middle of 302; a bidirectional lead screw 304 is rotatably installed inside the base rod 302, and the middle of the bidirectional lead screw 304 is fixedly connected to the output shaft of the drive motor 301; an internal threaded sleeve 305 is slidably sleeved at both ends of the base rod 302, and one end of the internal threaded sleeve 305 is screwed into the bidirectional lead screw 304; a male plug-in end 306 is fixedly installed at one end of the internal threaded sleeve 305 on one side; a female plug-in end 307 is fixedly installed at one end of the internal threaded sleeve 305 on the other side.

[0048] In practice, when the two sets of energy-absorbing door frames 1 are closed together, the drive motor 301 is started to control the bidirectional lead screw 304 to rotate, pushing out the internal thread sleeve 305. The two sets of internal support structures 3 are connected to each other through the plug-in male part 306 and the plug-in female part 307 to form a relatively integrated structure. The two sides of the internal support structures 3 are connected to the two sides of the bus door opening through the plug-in male part 306. At the same time, the support rod 303 is used to abut against the door frame body 101 to provide rigid support for the energy-absorbing door frame 1, further improving the impact resistance and anti-collision effect of the overall bus door.
