Description
Technical Field
[0001] The utility model belongs to the technical field of vehicle doors, in particular to a vehicle door assembly with a broken window structure and a vehicle. Background Art
[0002] Most of the glass in car windows is laminated glass. Compared with ordinary glass, laminated glass has the characteristics of strong adhesion, not easy to break, sound insulation and heat insulation, strong resistance, and high safety factor. It is precisely because of its strong resistance that when serious safety accidents such as vehicle collisions and rear-end collisions occur, the car doors cannot be opened but the windows are intact. In order to prevent accidents, a window-breaking hammer is generally placed at the car window, and the people in the car use the window-breaking hammer to break the car window glass to escape. However, if the accident is relatively serious and the car door cannot be opened, the people in the car may have been seriously injured or even lost consciousness, and it is impossible to manually use a window-breaking hammer to break the window, which makes it inconvenient for the people in the car to escape or for outsiders to rescue. Manual window breaking also increases the time for rescue. Utility Model Content

[0029] like Figure 1 As shown, the present application provides a vehicle door assembly with a window-breaking structure, including a door body, a vehicle window glass, and a window-breaking structure 1 arranged on the door body, the vehicle window glass being fixed on a vehicle window frame 50 of the door body. The door body of the present embodiment refers to all structures of the entire vehicle door structure except the vehicle window glass. For a vehicle with a window frame structure, the window-breaking structure 1 is installed on a window frame reinforcement plate 20. For a vehicle model without a window frame outside the vehicle window glass, the window frame 50 is the part outside the glass after the vehicle door is closed. The present embodiment mainly focuses on a structure in which the window-breaking structure 1 is installed on a window frame reinforcement plate 20.
[0030] In this embodiment, the inner door panel and the outer door panel are installed on both sides of the window frame reinforcement plate 20. The broken window structure 1 can be installed at the A-pillar, B-pillar or C-pillar, or at all of the A-pillar, B-pillar and C-pillar. The broken window component 11 is arranged along the length of the vehicle and faces the glass. If the broken window structure 1 is installed at the A-pillar or the B-pillar of the rear door, the cone head of the broken window component 11 protrudes from the window frame 50 and is arranged toward the rear. If it is installed in the door body at the B-pillar or the C-pillar of the front door, the cone head of the broken window component 11 protrudes from the window frame 50 and is arranged toward the front. The broken window component 11 in this embodiment is installed at the B-pillar of the front door.
[0031] The window-breaking structure 1 includes a window-breaking component 11 for breaking vehicle window glass. The window-breaking component 11 is arranged to protrude from the vehicle window frame 50 along the length direction of the vehicle. The window-breaking component 11 protrudes from the vehicle window frame 50 and is arranged toward the glass. There is a safety gap between the window-breaking component 11 and the vehicle window glass. When the vehicle is in normal use, the window-breaking component 11 will not interfere with the vehicle window glass. When the collision force is large, the window-breaking structure 11 contacts the vehicle window glass and breaks it.
[0032] The window breaking component 11 is arranged to reciprocate along the protruding direction of the window breaking component 11. The window breaking structure 1 also includes an elastic buffer and a first limiting portion. The first limiting portion is used to limit the extreme position of the window breaking component 11 moving away from the vehicle window glass. The elastic buffer is arranged between the window breaking component 11 and the door frame 40 of the door body. The first limiting portion blocks the movement direction of the window breaking component away from the vehicle window glass.
[0033] The window breaking structure 11 also includes a receiving hole arranged along the movement direction of the window breaking component, the elastic buffer and part of the window breaking component are received in the receiving hole, and the part of the window breaking component used for contacting the vehicle window glass is located outside the receiving hole, and the first limiting portion is the bottom of the receiving hole.
[0034] In this embodiment, the window breaking structure 11 includes a sleeve 12, and the inner hole of the sleeve 12 is a receiving hole.
[0035] The sleeve 12 is sleeved outside the window breaking component 11 , one end of the sleeve 12 is open and the other end is closed. The open end facilitates the extension of the window breaking component 11 , while the closed end holds the window breaking component 11 .
[0036] like Figure 4 As shown, the window breaking member 11 includes a first section 101 and a second section 102. The first section 101 passes through the sleeve 12, and the second section 102 is located in the sleeve 12. The top of the first section 101 is a window breaking cone, and the tip of the window breaking cone faces the vehicle window glass, which is convenient for squeezing the glass. The window breaking cone faces the direction of the thickness of the glass. It is best that the window breaking member 11 is perpendicular to the glass. For laminated glass, it is squeezed from the front in the thickness direction, which makes it easier to break.
[0037] An elastic buffer connected to the second section 102 is provided in the sleeve 12 , and the elastic buffer is used to buffer the sliding of the window breaking member 11 in the sleeve 12 .
[0038] The elastic buffer may be a rubber buffer pad or other elastic structure disposed between the bottom of the second section 102 and the sleeve 12. Figure 8 , Fig. 9 As shown, the elastic buffer in this embodiment is a coil spring 13 , and a groove 121 is provided on the side of the sleeve 12 away from the first section 101 , the groove 121 forms a first limiting portion, the groove 121 matches the second section 102 , and the coil spring 13 is sleeved outside the second section 102 .
[0039] The window breaking member 11 of this embodiment is cylindrical, and the first limiting portion is also a cylindrical groove 121. In a normal state, the bottom of the second section 102 is slightly deeper into the groove 121, so that when the window breaking member 11 is compressed, the groove 121 also has a certain guiding effect on the window breaking member 11. By adjusting the depth of the first limiting portion and the hardness of the coil spring 13, the collision force of the broken glass can be controlled.
[0040] Under normal circumstances, the first section 101 extends out of the sleeve 12 and has a certain safety distance from the vehicle window glass. When the force is large, the vehicle window glass shifts and contacts the first section 101. When the collision force of the vehicle is less than the preset vehicle window breaking force, the rear section of the window breaking component 11 slides into the groove 121, and the coil spring 13 buffers and limits the collision force to prevent the vehicle window glass from breaking. When the force is large to a certain extent, the side of the second section 102 away from the first section 101 contacts the bottom of the groove 121, and the window breaking component 11 cannot continue to move. If the collision force exceeds the preset breaking force, the second section 102 contacts the bottom of the groove 121, and the window breaking component 11 will generate a force in one direction on the glass to break it.
[0041] The inner wall of the accommodating hole protrudes inward with a second limiting portion 122 for limiting the extreme position of the movement of the window breaking component 11 toward the vehicle window glass. The window breaking component 11 has an anti-slip portion 103 for cooperating with the second limiting portion 122. The second limiting portion 122 blocks the movement direction of the anti-slip portion 103 toward the vehicle window glass.
[0042] The anti-slip portion 103 is located between the first section 101 and the second section 102. The outer diameter of the anti-slip portion 103 is smaller than the inner diameter of the sleeve 12. The sleeve 12 is provided with a second limiting portion 122 at one end of the opening. The second limiting portion 122 is used to limit the anti-slip portion 103 from sliding out of the sleeve 12. The coil spring 13 is located between the anti-slip portion 103 and the first limiting portion. Figure 8 and Fig. 9 shown.
[0043] To facilitate installation, Figure 4 , Figure 7 and Figure 8 As shown, at least one protrusion 104 is provided on the outer periphery of the anti-detachment portion 103, and the second limiting portion 122 is provided with a through groove 123 matching the protrusion 104. When the protrusion 104 is aligned with the through groove 123, the window breaking member 11 enters into the sleeve 12 or is taken out from the sleeve 12.
[0044] In this embodiment, four protrusions 104 are evenly arranged around the anti-slip portion 103 , and four through grooves 123 are correspondingly arranged on the second limiting portion 122 .
[0045] In order to prevent the window breaking member 11 from sliding out of the sleeve 12 after rotating relative to the sleeve 12 during driving, a limiting groove 124 is further provided on the second limiting portion 122, and the limiting groove 124 forms a blocking position for blocking the anti-slip portion 103. The number of the limiting grooves 124 corresponds to the number of the protrusions 104, and the limiting grooves 124 and the passing grooves 123 are staggered. The limiting groove 124 is set from the side of the second limiting portion 122 close to the second section 102 to the outside of the sleeve 12, but is not through. The through groove 123 is a through groove that penetrates the second limiting portion 122. After the protrusion 104 is aligned with the limiting groove 124, the window breaking component 11 is pressed downward. When the protrusion 104 has completely passed through the through groove 123, the window breaking component 11 is rotated so that the protrusion 104 is misaligned with the through groove 123, and the protrusion 104 enters the limiting groove 124, thereby preventing the window breaking component 11 from slipping out of the sleeve 12, thereby restricting the window breaking component 11.
[0046] The depth of the limiting groove 124 is greater than the depth of the groove 121, so as to prevent the bottom of the window-breaking member 11 from entering the first limiting portion when the collision force does not reach the set limit, while the top of the protrusion 104 is separated from the limiting groove 124, so as to prevent the protrusion 104 from not being able to enter the limiting groove 124 when the window-breaking member 11 is reset. In order to ensure that the protrusion 104 can smoothly enter the limiting groove 124 after the window-breaking member 11 rotates, the bottom of the limiting groove 124 can be designed to be trumpet-shaped for guidance.
[0047] Among them, Figure 3 As shown, the sleeve 12 is mounted on the bracket 14, and the bracket 14 is mounted on the window frame reinforcement plate 20 by bolts or welding. Fig.10 As shown, the bracket 14 includes a bottom plate 141, a first side plate 142 and a second side plate 143, the first side plate 142 and the second side plate 143 are both mounted on the bottom plate 141, the first side plate 142 and the second side plate 143 are spaced apart, and the sleeve 12 is mounted on the first side plate 142 and the second side plate 143 by welding. The bottom plate 141 is mounted on the window frame reinforcement plate 20 by bolts or welding, the outer wall of the sleeve 12 is arc-shaped, and the first side plate 142 and the second side plate 143 are provided with a receiving groove 144 for receiving the sleeve 12, the arc of the receiving groove 144 is preferably larger than half of the outer wall of the sleeve 12, and the sleeve 12 is more firmly welded to the first side plate 142 and the second side plate.
[0048] The inner door panel and the outer door panel are installed on both sides of the window frame reinforcement plate 20, respectively. A sealing strip 30 is designed around the edge of the glass on the window frame reinforcement plate 20. In order to enable the window-breaking component 11 to quickly break the glass, an opening can be designed on the sealing strip 30 corresponding to the window-breaking component 11. However, in order not to affect the waterproof effect, the diameter of the opening should be relatively small. The sealing strip 30 is plastic, and the window-breaking component 11 is made of tungsten steel with high hardness. In the event of an accident, the window-breaking component 11 can penetrate the sealing strip 30 and contact the glass. Under normal circumstances, the window-breaking component 11 is blocked by the sealing strip 30, which does not affect the lifting and lowering of the window glass or the appearance. After the window-breaking structure 1 and the glass are installed, they are shielded by the front door pillar buckle plate assembly.
[0049] The present application also provides a car including the above-mentioned door assembly with a broken window structure.
[0050] The vehicle door assembly and vehicle with a window-breaking structure provided in the present application can automatically shatter the vehicle window glass by the window-breaking component 11 when the vehicle is involved in a major accident and the door cannot be opened and needs to be removed, thereby omitting the step of manually breaking the window, reducing the action of breaking the window by people inside or outside the vehicle, and shortening the time for self-rescue of people inside the vehicle or rescue of people outside the vehicle.
[0051] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed in the present invention shall still be covered by the claims of the present invention.
