Abstract
Description
Technical Field
[0001] This utility model relates to the field of vehicle door lock technology, and in particular to a structure of a bus passenger door lock assembly. Background Technology
[0002] Door locks are the most common devices in daily life and are used in various fields, such as door locks on cars. However, in order to ensure the safety performance of the car itself, the structure of such door locks is quite complex, with complex transmission components in addition to the lock body.
[0003] Bus passenger door locks are installed on the passenger doors at the bus entrance. Most passenger doors are electrically or pneumatically operated to open and close automatically. However, most current bus passenger door locks do not provide feedback on whether the lock is open or closed. This means that the driver is unsure whether the passenger door lock is open when opening the door. If the door is opened while locked, it will damage the passenger door lock.
[0004] Publication (Announcement) No.: CN202990635U A bus passenger door lock, comprising an outer handle, a lock body, an inner cover plate, and an inner opening handle, characterized in that: the lock body and the inner opening handle are coaxially rotatably connected by a connecting shaft, and the connecting shaft is also provided with an operating arm, which is driven to rotate by the lock body, and the output end of the operating arm is connected to a pin through a pull rod.
[0005] The bus passenger door lock assembly exhibits several issues during use, including incoordination of the opening and closing control knob assembly, poor linkage, and insufficient locking tightness of the locking mechanism. Utility Model Content
[0006] The purpose of this utility model is to provide a bus passenger door lock assembly structure that solves the problems of flexible use and high operability between various component groups in the bus passenger door lock assembly structure.
[0007] The technical solution adopted by this utility model to solve its technical problem is: a bus passenger door lock assembly structure, including a connecting surface structure, an opening and closing control knob assembly disposed in the connecting surface structure, and a fixing member disposed on the door body. The outer end of the opening and closing control knob assembly is connected to a knob body disposed outside the connecting surface structure. The opening and closing control knob assembly includes a connecting screw disposed in the connecting surface structure, a four-corner opening shaft connected to the connecting screw, a knob body disposed outside the four-corner opening shaft, a connecting control component disposed between the knob body and the connecting surface structure, and a fan-shaped rotating arm structure disposed between the connecting control component and the connecting screw. The fan-shaped rotating arm structure is connected to the locking rod.
[0008] The connection control assembly includes a fixed base in the connection surface structure, a transmission plate between the knob body and the four corner opening shafts, an inner rotating block on the lower side of the transmission plate, an outer rotating block between the inner rotating block and the connection surface structure, a spring assembly in the inner rotating block, and a steel ball assembly corresponding to the spring assembly.
[0009] The aforementioned fan-shaped rotating arm structure includes a fan-shaped rotating arm body, a snap fastener connected to the fan-shaped rotating arm body, and an inner connecting rod. A set of indicator color blocks is provided on the end face of the fan-shaped rotating arm body.
[0010] The connecting surface structure includes a connecting panel body, a group of positioning mounting holes in the connecting panel body, and a sealing element body at the lower end of the connecting panel body.
[0011] The beneficial effects of this utility model are: the bus passenger door lock assembly is firmly connected to the door body, ensuring it will not loosen even after long-term use; the designed opening and closing control knob assembly and connecting control assembly ensure the assembly structure has high linkage and operational flexibility. This also protects the utility model from excessive rotation of the knob, preventing damage to other parts of the utility model.
[0012] The present invention will be described in more detail below with reference to the accompanying drawings and embodiments. Attached Figure Description

[0019] The terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end" used in the application text to indicate the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings. They are used solely for the convenience of describing the present invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0021] Example 1, as Figure 1-5 As shown, a bus passenger door lock assembly structure includes a connecting surface structure, an opening and closing control knob assembly disposed in the connecting surface structure, and a fixing member disposed on the door body. The connecting surface structure includes a connecting base 15, a connecting panel 1, a positioning member mounting hole group 2 disposed in the connecting panel, and a sealing member body 3 disposed at the lower end of the connecting panel.
[0022] The opening and closing control knob assembly includes a connecting screw 4 in the connecting surface structure, a four-corner opening shaft 5 connected to the connecting screw, a knob body 6 located outside the four-corner opening shaft, a connecting control component located between the knob body and the connecting surface structure, and a fan-shaped rotating arm structure located between the connecting control component and the connecting screw. The fan-shaped rotating arm structure is connected to the locking rod 7.
[0023] The connection control assembly includes a fixed base 8 in the connection surface structure, a transmission plate 9 between the knob body and the four corner opening shafts, an inner rotating block 10 on the lower side of the transmission plate, an outer rotating block 11 between the inner rotating block and the connection surface structure, a spring assembly 12 in the inner rotating block, and a steel ball assembly 13 corresponding to the spring assembly.
[0024] The aforementioned fan-shaped rotating arm structure includes a fan-shaped rotating arm body 14, a snap fastener 16 connected to the fan-shaped rotating arm body, and an inner connecting rod 17. A set of indicator color blocks 18 is provided on the end face of the fan-shaped rotating arm body 14.
[0025] The knob can rotate the fan-shaped rotating arm from the locked position to the open position, but cannot rotate it from the open position to the locked position; the four corner opening shafts can rotate the fan-shaped rotating arm from the locked position to the open position, and can also rotate it from the open position to the locked position.
[0026] The bus passenger door lock assembly is securely connected to the door body, ensuring it remains secure even after long-term use. The included opening / closing control knob and connecting control components ensure high flexibility and interlocking operation of the assembly. This design protects the device from excessive knob rotation, preventing damage to other parts of the device.
