Description

Technical Field

[0001] This utility model relates to the field of vehicle lock technology, and in particular to a push-out emergency window lock structure for passenger vehicles. Background Technology

[0002] Buses are equipped with outward-opening emergency windows, which can be opened in emergencies to serve as an emergency escape route. The outward-opening emergency window is normally closed by locking the vehicle. In the prior art, for example, the utility model patent: a door breakage emergency door lock with an opening alarm device (publication number: CN103835592A) discloses a lock body structure with an alarm device to realize the door opening alarm function. However, in the above result, the alarm device is set separately from the handle, which is inconvenient when installing the lock body structure and is also less economical.

[0020] The following will refer to the appendix in the embodiments of this utility model. Figures 1-4 The technical solutions in the embodiments of this utility model are clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0021] As shown in the figure, a push-out emergency window lock body 3 structure for a passenger vehicle includes a mounting bracket 1, a handle 2, and a lock body 3. The lower end of the handle 2 is rotatably mounted on the mounting bracket 1. A torsion spring is provided on the rotating shaft of the handle 2 for the return swing of the handle 2. The mounting bracket 1 has an installation opening 11. The lower end of the handle 2 forms a connecting part 21 that passes through the installation opening 11. A pull rod 4 connected to the lock body 3 is connected to the connecting part 21. The handle 2 is hollow inside and has a buzzer 23 that is connected to the vehicle's central control system. Specifically, the handle 2 is composed of two halves joined together. The buzzer 23 and its control circuit are located between the two halves of the handle 2. The handle 2 has several sound leakage holes 22 opposite to the buzzer 23.

[0022] In the above structure, the lock body 3 is fixedly installed on the emergency window frame via the mounting bracket 1. The lock body 3 is fixedly connected to the emergency window frame and matches the locking pin on the vehicle body. A sensor (generally a contact sensor, which is widely used in existing technology and will not be elaborated here) is installed between the emergency window and the vehicle body to monitor the opening and closing status of the emergency window and the vehicle body and is connected to the vehicle's central control system. By pulling the handle 2, the handle 2 swings, which in turn swings the connecting part 21. The connecting part 21 pulls the lever 4, which in turn swings the locking tongue of the lock body 3, thereby unlocking the emergency window and opening the emergency window. When the emergency window is open, the vehicle's central control system sends a signal to the buzzer 23, causing the alarm sound emitted by the buzzer 23 to pass through the sound leakage hole 22 and out of the handle 2, thus alerting the passengers to the current opening and closing status of the emergency window and reminding them to check. Since the buzzer 23 is integrated into the handle 2, the lock body 3 structure has better integration, which facilitates the installation of the lock body 3 structure and also improves economy.

[0023] In addition, based on the above structure, the handle 2 is provided with a switch 24 electrically connected to the buzzer 23 for turning off the buzzer 23. The button of the switch 24 protrudes from the side wall of the handle 2. When the buzzer 23 sounds an alarm, after the passengers identify the risk, they can press the switch 24 to turn off the buzzer 23 in time and cut off the alarm sound, so as to avoid affecting the passenger environment. It can also be used as an auxiliary means when the vehicle's central control system fails.

[0024] In addition, based on the above structure, the upper end of the handle 2 is provided with a Hall sensor 25 that is connected to the vehicle's central control system, and the mounting bracket 1 is provided with a magnet 12 opposite to the Hall sensor 25. When the handle 2 is pulled and swings, the handle 2 causes the Hall sensor 25 and the magnet 12 to generate relative displacement. The swing of the handle 2 is monitored by the cooperation of the Hall sensor 25 and the magnet 12, and abnormal swing or failure to reset of the handle 2 is monitored, which makes it easier for the accompanying personnel to identify risks.

[0025] In addition, based on the above structure, there are two lock bodies 3 and the pull rod 4 is a split pull rod 4. The main rod of the pull rod 4 is connected to the connecting part 21, and the two branch rods are respectively connected to the two lock bodies 3. When the handle 2 is pulled and the main rod of the pull rod 4 is driven, the two branch rods of the pull rod 4 simultaneously drive the two lock bodies 3 to move, thereby opening the emergency window. By setting two lock bodies 3, the stability of the emergency window when it is closed with the vehicle body is enhanced.

[0026] In addition, based on the above structure, the lock body 3 is a plate lock. Compared with the traditional hard spring plate lock body 3 structure, the plate lock has the advantage of requiring less force to open and close. While facilitating the opening and closing of the emergency window, it prevents the rubber strip between the emergency window and the vehicle body from deforming and aging due to excessive force during opening and closing, which could cause abnormal noise and water leakage.

[0027] In addition, based on the above structure, a cover plate 5 is also included. The lower end of the cover plate 5 is rotatably connected to the mounting bracket 1, so that the cover plate 5 can swing to cover the handle 2. When the handle 2 is not in use, the cover plate 5 can be swung to cover the handle 2, preventing passengers from accidentally opening the emergency window by operating the handle 2. Furthermore, a marking pattern is set on the outer side of the cover plate 5 by laser printing, which makes it easy for passengers to identify the location and open the emergency window in an emergency.

[0028] Furthermore, based on the above structure, a snap-fit ​​groove 51 is formed at the upper end of the cover plate 5, and a snap-fit ​​rod 13 matching the snap-fit ​​groove 51 is formed on the mounting frame 1. When the cover plate 5 covers the handle 2, the snap-fit ​​rod 13 is snapped into the snap-fit ​​groove 51. The cooperation between the snap-fit ​​groove 51 and the snap-fit ​​rod 13 limits the swing of the cover plate 5 relative to the mounting frame 1, restricting the free swing of the cover plate 5 when it is not subjected to external force, so that the cover plate 5 can cover the handle 2 more stably.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
