Description

TECHNICAL FIELD

[0001] The utility model belongs to vehicle technical field, concretely relates to a rear door broken window structure and vehicle. BACKGROUND

[0002] When the vehicle has an accident and the door cannot be opened, the people in the vehicle need to break the window to escape, so it is necessary to configure a broken window tool in the vehicle. However, if the broken window tool is fixed on the four door glass, since the four door is used frequently as a moving part, it is easy to be accidentally touched, and the four door is also not suitable for installing the broken window tool as the part that the driver and the passenger can perceive most obviously. For this reason, the vehicle does not generally configure a fixed broken window tool at present, and the only way to deal with an emergency is to provide a broken window tool in the vehicle for emergency use. However, since the broken window tool is not a commonly used item and is not fixed in position, it is easy to be hidden by other items in the vehicle and cannot be quickly found in an emergency, thereby affecting the timing of breaking the window to escape. SUMMARY

[0003] The utility model embodiment provides a rear door broken window structure and vehicle, aims at guaranteeing the exquisite feeling of the vehicle interior and improving the convenience of breaking the window to escape.

[0004] To achieve the above-mentioned purpose, the utility model adopts the technical scheme of: in the first aspect, a rear door broken window structure is provided, which comprises a rear door body, a rear door glass, a rear door interior panel, and a broken window hammer. A window is formed in the rear door body, the rear door glass is fixedly connected to the boundary part of the window, and the rear door interior panel is connected to the inner side of the rear door body around the boundary of the window. The broken window hammer is arranged between the rear door body and the rear door interior panel. The rear door body is provided with a broken window hole through which the hammer head of the broken window hammer passes, the rear door glass covers the broken window hole, and the rear door interior panel is provided with an emptying opening corresponding to the part of the broken window hammer. The emptying opening is detachably connected with a broken window cover plate.

[0005] In combination with the first aspect, in a possible implementation manner, the broken window hammer comprises a guide seat and a hammer body. The guide seat is fixedly connected to the rear door body and aligned with the broken window hole. The hammer body is slidably arranged in the guide seat along the axial direction of the broken window hole, and the end of the hammer body facing the broken window hole forms a pointed hammer head. The guide seat can guide the movement track of the hammer body. When breaking the window, the broken window hammer does not need to be removed, and the tail part of the broken window hammer can be directly subjected to an external force to make the broken window hammer linearly impact the rear door glass under the guidance of the guide seat. Compared with the prior art in which the broken window hammer is first found and then manually operated, the operation convenience can be improved.

[0006] In some embodiments, the guide seat has a sliding hole axially aligned with the window breaking hole, the hammer body slides in the sliding hole, and a limiting structure is arranged between the hammer body and the sliding hole, which at least limits the axial movement of the hammer body. The sliding hole guides the movement of the hammer body, and the limiting structure limits the axial movement of the hammer body to prevent the hammer body from sliding out of the sliding hole.

[0007] For example, the limiting structure includes at least one limiting slot formed on the inner wall of the sliding hole along the axial direction, and at least one limiting rib arranged on the circumferential wall of the hammer body, each limiting rib is respectively connected to each limiting slot and slidably matched with the limiting slot. The limiting slot and the limiting rib arranged on the hammer body are matched to limit the axial movement of the hammer body, and also limit the circumferential rotation freedom of the hammer body, thereby improving the installation stability and movement stability of the hammer body.

[0008] For example, an elastic member is arranged between the guide seat and the hammer body, and the elastic member is used to push the hammer body away from the back door glass. When the hammer body needs to break the window, an external force is applied to the tail end of the hammer body to overcome the elastic force of the elastic member, so that the hammer head penetrates through the window breaking hole and linearly impacts the edge of the back door glass to break the window. The elastic member maintains the elastic pushing force on the hammer body to keep a safe distance between the hammer head and the back door glass, thereby avoiding the hammer head from freely colliding with the back door glass to cause the back door glass to break, and also avoiding the hammer head from moving to produce abnormal noise due to the jolt of the vehicle body.

[0009] In some embodiments, the end of the guide seat away from the back door glass is provided with a ring groove surrounding the sliding hole, and the end of the hammer body away from the back door glass is provided with a convex edge. The elastic member is arranged in the ring groove, and the two ends of the elastic member abut against the convex edge and the groove bottom of the ring groove respectively to form a compressed state. The elastic member is arranged in the ring groove in a compressed state to push the convex edge, so that the hammer body obtains a stable elastic force to maintain a stable state in which the hammer head is separated from the back door glass. The convex edge also shields the opening of the ring groove, thereby avoiding the exposure of the elastic member to affect the appearance of the interior decoration.

[0010] For example, the opposite two side edges of the window breaking cover plate are each provided with at least one buckle, and each buckle is respectively buckled to the edge of the avoidance opening. The edge of the avoidance opening is buckled by each buckle to fix the window breaking cover plate on the back door interior panel, which not only ensures the integrity of the back door interior panel, but also facilitates disassembly, thereby improving the convenience of window breaking escape for the people inside the vehicle.

[0011] For example, the edge of the avoidance opening or the window breaking cover plate is provided with a dismounting opening. The person inside the vehicle can insert the fingertips into the dismounting opening to buckle the window breaking cover plate outward, so that the buckle is deformed under stress and separated from the edge of the avoidance opening, thereby the window breaking cover plate can be dismounted, which is simple and convenient to operate.

[0012] In some embodiments, the outer surface of the back door body is provided with a groove around the window, the back door glass is embedded in the groove, and the breakage window hole is arranged on the groove bottom wall. Embedding the back door glass in the groove can improve the installation stability of the back door glass, and arranging the breakage window hole on the groove bottom can shield the breakage window hole by the edge part of the back door glass embedded in the groove, thereby avoiding the breakage window hole from being exposed and affecting the overall appearance quality of the back door.

[0013] The back door breakage structure has the advantages that, compared with the prior art, the back door breakage structure of the utility model sets the breakage hammer between the back door body and the back door interior panel, and covers the emptying opening by the breakage cover plate to ensure the integrity of the back door interior panel, so that the breakage hammer can be prevented from being exposed to affect the delicate feeling of the vehicle interior, and compared with the prior art of installing the breakage hammer at the side door position, the back door breakage structure can prevent the occupation of the seating space of the driver and passenger from affecting the driving and riding experience; when an emergency occurs and breakage is needed in the vehicle to escape, the breakage cover plate can be removed to expose the breakage hammer, and the hammer head can be made to pass through the breakage window hole and impact on the back door glass by applying external force to the breakage hammer, so that the back door glass is broken; since the breakage hammer is arranged in a fixed position, compared with the prior art that the breakage hammer lacks a fixed placement position in the vehicle, the driver and passenger can find the position of the breakage hammer in the first time when needed to break the window and escape, so that the convenience of breakage escape is improved, and the breakage escape opportunity is avoided to be missed due to the failure to find the breakage hammer in time.

[0014] In a second aspect, the utility model embodiment further provides a vehicle comprising the back door breakage structure.

[0015] Compared with the prior art, the vehicle of the utility model adopts the back door breakage structure, so that the breakage hammer can be prevented from being exposed to affect the delicate feeling of the vehicle interior; the driver and passenger can find the position of the breakage hammer in the first time when needed to break the window and escape, so that the convenience of breakage escape is improved, and the breakage escape opportunity is avoided to be missed due to the failure to find the breakage hammer in time.

[0026] Please refer to Figures 1 to 7The utility model provides a back door broken window structure, which comprises a back door body 10, a back door glass 20, a back door interior trim 30 and a broken window hammer 40. The back door body 10 is provided with a window 101. The back door glass 20 is fixedly connected to the boundary of the window 101. The back door interior trim 30 is connected to the inner side of the back door body 10 around the boundary of the window 101. The broken window hammer 40 is arranged between the back door body 10 and the back door interior trim 30. The back door body 10 is provided with a broken window hole 102 through which the hammer head 421 of the broken window hammer 40 passes. The back door glass 20 covers the broken window hole 102. The back door interior trim 30 is provided with an emptying opening 301 corresponding to the position of the broken window hammer 40. The emptying opening 301 is detachably connected to a broken window cover plate 302.

[0027] It should be noted that the back door interior trim 30 and the inner side of the back door body 10 (i.e. the side facing the interior of the vehicle body) are fixedly connected, and a separation space (i.e. a sandwich layer) is formed between the two. Specifically, the outer side of the back door body 10 (i.e. the side facing the exterior of the vehicle body) is provided with a glass mounting hole, and the back door glass 20 is provided with a glass mounting column suitable for inserting into the glass mounting hole, thereby ensuring the connection reliability of the back door glass 20 and the back door body 10. The inner side of the back door body 10 is provided with a trim mounting hole, and the back door interior trim 30 is provided with a trim mounting column suitable for inserting into the trim mounting hole, thereby ensuring the connection reliability of the back door interior trim 30 and the back door body 10 through the insertion and cooperation.

[0028] In this embodiment, the broken window hammer 40 is arranged in the sandwich layer formed between the back door interior trim 30 and the back door body 10, and is suitable for the in-vehicle personnel to apply external force to the broken window hammer 40 by opening the emptying opening 301 in the back door interior trim 30. Of course, in order to ensure the integrity of the back door interior trim 30, the detachable broken window cover plate 302 is mounted on the emptying opening 301. The specific detachable connection structure can be that the edge of the broken window cover plate 302 and the boundary of the emptying opening 301 are mutually clamped and cooperated.

[0029] Specifically, the broken window hammer 40 can be arranged at any position on the edge of the window 101. In view of the convenience of operation and the effect of breaking the window, the broken window hammer 40 is preferably arranged at the middle region of the lower edge of the window 101. In this way, when the broken window cover plate 302 is opened and external force is applied to the broken window hammer 40, the hammer head 421 can pass through the broken window hole 102 and hit the middle part of the lower edge of the back door glass 20, so as to cause the back door glass 20 to break and crack or directly break.

[0030] Compared with the prior art, the broken window structure of the back door provided by the embodiment sets the broken window hammer 40 between the back door body 10 and the back door inner panel 30, and covers the emptying port 301 by the broken window cover plate 302 to ensure the integrity of the back door inner panel 30, so as to avoid the exposure of the broken window hammer 40 affecting the delicate feeling of the vehicle interior; when an emergency occurs and window breaking is needed in the vehicle, the broken window cover plate 302 can be removed to expose the broken window hammer 40, and the hammer head 421 can be made to impact the back door glass 20 by applying an external force to the broken window hammer 40, so as to break the back door glass 20. Since the breaking hammer is arranged in a fixed position, the vehicle occupant can find the position of the breaking hammer in the first time when needed to break the window and escape, thereby improving the convenience of window breaking and escaping, and avoiding the delay of the window breaking and escaping opportunity due to the failure to find the broken window hammer 40 in time.

[0031] In some embodiments, referring to Figures 4 to 6 , the broken window hammer 40 includes a guide seat 41 and a hammer body 42. The guide seat 41 is fixedly connected to the back door body 10 and aligned with the broken window hole 102. The hammer body 42 is slidably arranged in the guide seat 41 along the axis of the broken window hole 102, and the end of the hammer body 42 towards the broken window hole 102 is formed as a pointed hammer head 421.

[0032] The guide seat 41 can be fixed to the inner side of the back door body 10 by adhesion, welding or screwing. The hammer body 42 is a polygonal or circular column structure, and the end thereof towards the back door glass 20 is formed as a pointed hammer head 421. The hammer body 42 is inserted into the guide seat 41. When window breaking is needed in an emergency, the vehicle occupant can remove the broken window cover plate 302 to expose the tail of the hammer body 42, and then apply an external force (such as hitting by hand or with a tool) to the tail of the hammer body 42, so that the hammer body 42 makes a linear impact motion towards the back door glass 20 under the guidance of the guide seat 41, and the pointed hammer head 421 passes through the broken window hole 102 to act on the back door glass 20 to complete the window breaking. The guide seat 41 can provide a fixed installation position for the hammer body 42, and guide the movement of the hammer body 42 to ensure the linearity of the movement of the hammer body 42, thereby reducing the operation difficulty and improving the window breaking effect.

[0033] It should be noted that, referring to Figure 5 and Figure 6The guide base 41 has a sliding hole 411 axially aligned with the window breaking hole 102, the hammer body 42 is slidably arranged in the sliding hole 411, and a limiting structure is arranged between the hammer body 42 and the sliding hole 411, which at least limits the axial movement of the hammer body 42. Here, the limiting structure can limit the axial movement of the hammer body 42 relative to the guide base 41, thereby preventing the hammer body 42 from sliding out of the sliding hole 411; of course, in order to improve the stability of the movement of the hammer body 42 in the sliding hole 411, the limiting structure not only limits the axial movement of the hammer body 42, but also limits the rotational freedom of the hammer body 42 in the sliding hole 411, thereby avoiding the influence of the stability of the static state and the convenience of the movement state caused by the arbitrary rotation of the hammer body 42.

[0034] As shown in Figure 5 and Figure 6 , the limiting structure includes at least one limiting groove 412 formed on the inner wall of the sliding hole 411 along the axial direction of the sliding hole 411, and at least one limiting rib 422 arranged on the peripheral wall of the hammer body 42, each limiting rib 422 is respectively connected to each limiting groove 412 and slidably matched with the limiting groove 412. Here, one limiting groove 412 on the sliding hole 411 and one limiting rib 422 on the hammer body 42 can limit the axial movement and the rotational freedom of the hammer body 42, of course, considering the reliability and stability of the limiting, a plurality of limiting grooves 412 can be arranged on the peripheral wall of the sliding hole 411, and a plurality of limiting ribs 422 can be arranged on the peripheral wall of the hammer body 42, and the plurality of limiting grooves 412 and the plurality of limiting ribs 422 are slidably matched one by one, thereby limiting the sliding distance of the limiting rib 422 by the length of the limiting groove 412, thereby limiting the axial movement of the hammer body 42, and limiting the rotational freedom of the hammer body 42 by the clamping of the limiting groove 412 along the circumferential direction of the hammer body 42, thereby improving the stability of the movement of the hammer body 42.

[0035] In some possible implementation manners, please refer to Figure 4 , the guide base 41 and the hammer body 42 are provided with an elastic member 43, which is used to push the hammer body 42 in a direction away from the back door glass 20. Here, the elastic member 43 can be a spring, which applies an elastic pushing force to the hammer body 42, and when the window needs to be broken, an acting force is applied to the tail end of the hammer body 42 to overcome the elastic force of the elastic member 43, so that the hammer head 421 can pass through the window breaking hole 102 and linearly impact the edge of the back door glass 20 to break the window; here, the elastic pushing force of the elastic member 43 on the hammer body 42 can keep a safe distance between the hammer head 421 and the back door glass 20, thereby avoiding the free collision of the hammer head 421 with the back door glass 20 to cause the breakage of the back door glass 20, and also avoiding the problem of abnormal noise caused by the movement of the hammer head 421 due to the bumping of the vehicle body.

[0036] Specifically, as shown in Figures 4 to 6 , the end of the guide seat 41 away from the back door glass 20 is provided with a ring groove 413, and the ring groove 413 is arranged around the sliding hole 411, and the end of the hammer body 42 away from the back door glass 20 is provided with a convex edge 423; wherein the elastic member 43 is arranged in the ring groove 413, and the two ends of the elastic member 43 are respectively abutted with the convex edge 423 and the groove bottom of the ring groove 413 to form a compressed state. The elastic member 43 is arranged in the ring groove 413 in a compressed state to push the convex edge 423, so that the hammer body 42 obtains a stable elastic force to maintain a stable state in which the hammer head 421 is separated from the back door glass 20, and at the same time, the convex edge 423 can also shield the opening of the ring groove 413, thereby avoiding the exposure of the elastic member 43.

[0037] The optional structure of the above-mentioned guide seat 41 is shown in Figure 5 , which includes a fixed plate, an inner sleeve and an outer sleeve; wherein the fixed plate is bonded, welded or screwed to the metal plate on the inner side of the back door body 10, and a through hole is formed in the fixed plate and aligned with the broken window hole 102; the inner sleeve is fixedly connected to the side of the fixed plate away from the back door glass 20 and coaxial with the through hole, and the inner cavity of the inner sleeve and the through hole jointly form the sliding hole 411, the outer sleeve is coaxially arranged on the periphery of the inner sleeve and forms the ring groove 413 with the inner sleeve, the diameter of the convex edge 423 matches the inner diameter of the outer sleeve, and the length of the outer sleeve is greater than the length of the inner sleeve, and the convex edge 423 is flush with the end face of the outer sleeve under the pushing action of the elastic member 43, thereby avoiding the exposure of the hammer body 42.

[0038] Please refer to Figure 2 and Figure 3 , the opposite two side edges of the broken window cover plate 302 are provided with at least one buckle 3021, and each buckle 3021 is respectively buckled to the edge of the avoidance opening 301. By buckling each buckle 3021 to the edge of the avoidance opening 301, the broken window cover plate 302 is fixed on the back door inner panel 30, which not only ensures the integrity of the back door inner panel 30, but also facilitates disassembly, thereby improving the convenience of window breaking for the people inside the vehicle.

[0039] It should be noted that, in order to facilitate disassembly of the broken window cover plate 302, referring to Figure 4 and Figure 7 , the edge of the avoidance opening 301 or the broken window cover plate 302 is provided with a dismounting opening 303. When the emergency window breaking operation is needed, the person inside the vehicle can insert the fingertips into the dismounting opening 303 to buckle the broken window cover plate 302 outward, so that the buckle 3021 is deformed under stress and separated from the edge of the avoidance opening, thereby the broken window cover plate 302 can be removed, which is simple and convenient to operate.

[0040] It should be understood that, in the present embodiment, referring to Figure 4The outer side surface of the back door body 10 is provided with a groove 103 surrounding the window 101, the back door glass 20 is embedded in the groove 103, and the breakage window hole 102 is arranged on the groove bottom wall surface of the groove 103. Embedding the back door glass 20 in the groove 103 can improve the mounting stability of the back door glass 20, and arranging the breakage window hole 102 on the groove bottom of the groove 103 can shield the breakage window hole 102 by the edge part of the back door glass 20 embedded in the groove 103, so as to avoid the breakage window hole 102 from being exposed and affecting the overall appearance quality of the back door.
