[0002] As people pay more and more attention to green travel modes in modern life, environmentally friendly and low-carbon travel modes have been more and more popularized and promoted. Urban public buses have become the preferred means of transportation for many people. Moreover, with the development of public transportation vehicle technology and the continuous improvement of people's safety awareness, in order to further ensure the safety of drivers and prevent passengers from posing a safety impact and threat to drivers, existing urban buses usually have driver's surround doors in the driving area which serves as the bus operation and monitoring center, giving the driver an independent driving space and providing safety protection to a certain extent.

[0003] Existing bus driver's surround locks usually adopt an inner and outer knob structure, that is, a knob structure is adopted on the side close to the driver and the side close to the passenger. The driver can manually turn the knob to lock or unlock the surround door. However, the knob close to the driver's side has a smaller overall structure. When the driver turns the knob to open the surround door, the operation is less convenient and inconvenient. Utility Model Content

[0027] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0028] like Figures 1 to 3As shown, this embodiment provides a bus driver's surrounding lock device, which includes: a lock body 1, a lock tongue 2, a first handle 3, and a second handle 4. The lock tongue 2, the first handle 3, and the second handle 4 are all disposed on the lock body 1. One end of the first handle 3 is rotatably connected to the lock body 1, and the other end of the first handle 3 extends beyond the bottom end of the lock body 1. The first handle 3 is disposed on one side of the lock body 1 and is used for the bus driver to hold and operate. The second handle 4 is disposed on the other side of the lock body 1 and is used for the passenger to hold and operate. The first handle 3 and the second handle 4 are both transmission-connected to the lock tongue 2 and can drive the lock tongue 2 to move, so that the lock tongue 2 has a first locked position and a first unlocked position. When the lock tongue 2 is in the first locked position, the lock tongue 2 extends out of the lock body 1. When the lock tongue 2 is in the first unlocked position, the lock tongue 2 retracts into the lock body 1. It should be noted that the bus driver's surrounding lock device is installed on the surrounding door to enable the surrounding door to be closed, locked, or unlocked. With such arrangement, the bus driver can manually rotate the first handle 3 to retract the lock tongue 2 into the lock body 1, thereby unlocking the door and opening the surrounding door. During manual operation, the first handle 3 located on the side close to the bus driver can effectively increase the contact area with the bus driver, making it easier for the driver to grasp the door. In addition, the other end of the first handle 3 extends out of the bottom end of the lock body 1, which further facilitates the bus driver to complete the hand-held rotation action, greatly improving the convenience of operation.

[0029] In this embodiment, the lock body 1 includes a first lock body 1 and a second lock body 1 , the first lock body 1 is connected to the second lock body 1 , the first handle 3 is provided on the first lock body 1 , and the second handle 4 is provided on the second lock body 1 .

[0030] Optionally, the second handle 4 adopts a hook type and is embedded in the lock body 1. In this way, the embedded hook type handle structure is adopted to avoid interference and scratching with passengers, and at the same time, it is more time-saving and labor-saving to operate.

[0031] Optionally, the surrounding lock device for bus drivers also includes a locking knob 5, which is arranged on the same side as the first handle 3. The locking knob 5 is rotatably connected to the lock body 1 and has a second locking position and a second unlocking position. When the locking knob 5 is in the second locking position, the second handle 4 is restricted from driving the lock tongue 2 to retract the lock body 1.

[0032] Specifically, this embodiment exemplifies the following solution: the surrounding door rotates around the rotation axis. When the locking knob 5 is not turned to the second locking position, the bus driver can open the surrounding door through the first handle 3, and the passenger can open the surrounding door through the second handle 4. Once the bus driver turns the locking knob 5 to the second locking position, the locking knob 5 drives the latch to extend into the rotation area of the rotation axis of the surrounding door, thereby locking the rotation axis of the surrounding door. At this time, the passenger cannot open the surrounding door through the second handle 4.

[0033] Optionally, the bus driver's surrounding lock device further includes an unlocking assembly 6, which is disposed on the same side as the second handle 4. The unlocking assembly 6 is configured to release the restriction imposed on the second handle 4 when the locking knob 5 is in the second locked position, thereby enabling the second handle 4 to retract the lock tongue 2 into the lock body 1. Furthermore, the unlocking assembly 6 includes an unlocking knob that is rotatably connected to the lock body 1 and has a third unlocked position. When the unlocking knob is in the third unlocked position, the second handle 4 can retract the lock tongue 2 into the lock body 1. With this arrangement, during normal operation of the bus driver, the surrounding door is locked from the inside (driver's side) and cannot be opened from the outside (passenger side). If the driver suddenly becomes unwell and is unable to move, a passenger can turn the unlocking knob to the third unlocked position, pull the second handle 4 to retract the lock tongue 2 into the lock body 1, open the surrounding door, and enter the cab to provide assistance, further enhancing the safety of the entire vehicle.

[0034] Optionally, in order to better protect the unlocking knob and prevent passengers from accidentally touching it under normal circumstances, the unlocking assembly 6 also includes a protective cover. A mounting groove is recessed on the lock body 1, and the unlocking knob is arranged in the mounting groove. The protective cover is arranged on the unlocking knob and can open or close the notch of the mounting groove.

[0035] Furthermore, the bus driver's surrounding lock device also includes a buzzer 7, which is provided on the lock body 1 and is used to detect whether the protective cover is opened or closed. When the protective cover is opened, the buzzer 7 produces an alarm sound, and when the protective cover is closed, the buzzer 7 automatically silences the alarm sound. This can alert the driver of the working status of the unlocking component 6 and prevent the protective cover from being left open when the driver is not in use.

[0036] Optionally, in order to achieve lightweight protection cover and further improve the strength of the protection cover, the protection cover is made of aluminum alloy. Of course, in other embodiments, the material of the protection cover can also be set according to actual needs, and no further restrictions are made here.

[0037] In this embodiment, the surrounding lock device for bus drivers further includes a first push arm, which can drive the lock tongue 2 to move, and the first handle 3 can drive the first push arm to move.

[0038] Optionally, the surrounding lock device for bus drivers further includes a second push arm, which can drive the lock tongue 2 to move, and the second handle 4 can drive the second push arm to move.

[0039] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
