Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, specifically to a safety door and a bus having the same. Background Technology

[0002] The safety doors on buses are a crucial structural element for ensuring driver safety. They isolate the driver from the internal and external environments, providing effective protection. Safety doors are typically equipped with locks to prevent accidental opening during normal driving.

[0003] However, the existing safety doors have poor locking performance and cannot maintain their stability when the bus travels on bumpy roads or experiences severe vibrations and collisions. This makes it easy for the safety doors to loosen or open unexpectedly, resulting in the driver being unable to effectively rely on the safety door's protective function when protection is needed, and thus safety cannot be effectively guaranteed. Utility Model Content

[0036] Example 1

[0037] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, this embodiment provides a security door, including a door frame 10 and a door panel 12. The door frame 10 is mounted on a floor frame 11. One side of the door panel 12 is hinged to the door frame 10. The door panel 12 is provided with a swinging door handle 121 and a locking rod 122 that rotates with the swinging of the door handle 121. The floor frame 11 is provided with a first locking groove 111. One end of the locking rod 122 is provided with a locking part 1221 that can be rotatably engaged with or rotatably disengaged from the first locking groove 111. The door frame 10 is provided with a stop block 101. The other end of the locking rod 122 is provided with a limiting part 1222 that can be rotatably abutted against or rotatably disengaged from the stop block 101. The floor frame 11 is also provided with a second locking groove 112. The bottom inner side of the door panel 12 is provided with a locking fastener 123 that can be engaged with or disengaged from the second locking groove 112.

[0038] Specifically, the safety door is equipped with multiple locking mechanisms. By swinging the door handle 121, the locking rod 122 can be rotated, thereby enabling the locking part 1221 to engage or disengage from the first locking groove 111, and simultaneously enabling the limiting part 1222 to abut or disengage from the stop block 101. When the locking part 1221 engages with the first locking groove 111, the door panel 12 is firmly locked, and the limiting part 1222 abuts against the stop block 101, further locking the door panel 12 and preventing the door panel 12 from being accidentally opened due to vehicle bumps or vibrations, thus further improving safety. Conversely, when the locking part 1221 disengages from the first locking groove 111 and the limiting part 1222 disengages from the stop block 101, the door panel 12 can be opened smoothly.

[0039] Furthermore, the locking element 123 engages with the second locking groove 112, and the locking element 123 can only be unlocked from the inside of the door panel 12 (i.e., inside the driver's cab), ensuring that the door panel 12 cannot be easily opened from the outside, thus enhancing the protective effect of the safety door and further improving the reliability of the safety door locking.

[0040] Thus, through multiple locking mechanisms and an internal unlocking design, the safety door not only ensures the safety of the driver inside the cab, but also enhances the stability of the locking mechanism, avoids the risk of accidental unlocking, and ensures that the safety door remains firmly locked during driving.

[0041] like Figure 1 As shown, in this embodiment, the locking device 123 includes a fixing frame 1231 disposed on the inner side of the door frame 10, a pressure rod 1232 vertically disposed on the fixing frame 1231, and a limiting spring 1233 that keeps the pressure rod 1232 pressing towards the floor frame 11. The limiting spring 1233 is disposed between the fixing frame 1231 and the pressure rod 1232, and the limiting spring 1233 is sleeved on the pressure rod 1232.

[0042] Specifically, the pressure rod 1232 is inserted into the second lock groove 112. The spring force of the limiting spring 1233 keeps the pressure rod 1232 tightly against the bottom of the second lock groove 112, ensuring a tight engagement between the pressure rod 1232 and the second lock groove 112. This prevents the two from disengaging due to vehicle bumps or vibrations, thereby further improving the stability of the door lock. To unlock, simply pull the pressure rod 1232 from inside the driver's cab to disengage it from the second lock groove 112, and the door panel 12 can be easily opened.

[0043] like Figure 3 As shown, in this embodiment, the first lock groove 111 is an arc-shaped groove, and the locking part 1221 is an L-shaped first bend structure. The first bend structure moves along the arc-shaped trajectory of the first lock groove 111 as the locking rod 122 rotates, achieving precise engagement or disengagement, thereby smoothly locking or unlocking the door panel 12.

[0044] like Figure 2 As shown, in this embodiment, the limiting part 1222 is an L-shaped second bend structure, and the stop block 101 is set at the top of the door frame 10. The second bend structure rotates with the locking rod 122 to abut or disengage from the stop block 101, thereby locking or unlocking the door panel 12. When the second bend structure abuts against the stop block 101, the door panel 12 is firmly limited. With the dual protection of the first bend structure and the second bend structure, the door panel 12 can be stably locked even under complex conditions, effectively preventing accidental opening and improving driving safety.

[0045] Furthermore, when the locking rod 122 is rotated, the first and second bent structures rotate synchronously with the locking rod 122, thereby enabling the upper and lower ends of the door panel 12 to lock or unlock synchronously, ensuring easy operation.

[0046] like Figure 4 and Figure 5 As shown, in this embodiment, one end of the door handle 121 is hinged to the door panel 12. A swing block 1223 is provided in the middle of the locking rod 122. A connecting rod structure 1211 is provided between the door panel 12 and the swing block 1223 to drive the locking rod 122 to rotate. When the door handle 121 rotates, the locking rod 122 rotates synchronously through the connecting rod structure 1211 and the swing block 1223, thereby driving the first bend structure and the second bend structure to rotate synchronously, realizing the locking or unlocking of the door panel 12.

[0047] Furthermore, the linkage structure 1211 includes a fixed rod 12111 disposed on the inner side of the door handle 121 and a connecting rod 12112 shaft-connected between the fixed rod 12111 and the swing block 1223. Thus, through the linkage of the fixed rod 12111, the connecting rod 12112 and the swing block 1223, the locking rod 122 rotates smoothly and precisely, further optimizing the smoothness of locking or unlocking the door panel 12.

[0048] Example 2

[0049] A second aspect of this embodiment also provides a bus, including a safety door as described in Embodiment 1. Through the multiple locking mechanisms of the safety door, not only is the stability of the door panel 12 enhanced, but the overall safety is also improved. Even under complex road conditions, the door panel 12 can remain tightly locked. Furthermore, the locking fastener 123 is located on the inner side of the door panel 12 and can only be opened by the driver from inside the driver's cab, effectively preventing external intrusion and ensuring the driver's safety during driving.

[0050] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
