A device for opening a luggage compartment door lock for a vehicle

Abstract

The invention discloses a vehicle luggage compartment door opening device comprising a base. A pneumatic opening mechanism, a hand opening mechanism, a main revolving shaft and an auxiliary revolving shaft are arranged on the base. The pneumatic opening mechanism comprises an air cylinder, a main gear and an auxiliary gear, the main gear is sleeved on the main revolving shaft, the auxiliary gear is mounted on the auxiliary revolving shaft, the main gear and the auxiliary gear are in engaged linkage, and a main gear reset spring capable of resetting the main gear after revolving is also mounted on the main revolving shaft. The cylinder is fixedly mounted on the base, an extension block which is in touch rotation with an output shaft of the output shaft of the cylinder extends out is formed on the main gear integrally, and the cylinder is further provided with a control connector capable of being connected with a vehicle control system. All middle transmission components are omitted in the pneumatic opening mechanism, so that product structure is simplified to the utmost extent, production cost is reduced effectively, and user operation is facilitated.

Description

technical field [0001] The invention relates to a device for opening a luggage compartment door lock for a vehicle. Background technique [0002] The vehicle luggage compartment door lock opening device is generally installed on the luggage compartment door at the bottom of both sides of the bus body, and is mainly used to open and lock the luggage compartment door of the bus. At present, most of the existing vehicle luggage compartment door lock opening devices are upturning rotary vehicle luggage compartment door lock opening devices and upward moving vehicle luggage compartment door lock opening devices. These vehicle luggage compartment door lock opening devices need Flipping the operating handle drives the internal transmission mechanism to rotate. It is inconvenient for the user to exert force when opening and closing the vehicle door. Moreover, these existing luggage compartment door lock opening devices for vehicles have complex internal structures and high productio...

Problems solved by technology

At present, most of the existing vehicle luggage compartment door lock opening devices are upturning rotary vehicle luggage compartment door lock opening devices and upward moving vehicle luggage compartment door lock opening devices. These vehicle luggage compartment door lock opening devices need Flip the operating handle to drive the internal transmission mechanism to rotate. It is inconvenient for the user to use force when opening and closing the car door. Moreover, the internal structure of the existing luggage compartment door lock opening devices for vehicles is complicated, and the production cost is relatively high.

[0003] In view of the insufficiency of the existing technology, the applicant has applied for an invention patent named a luggage compartment door lock opening device for a vehicle, and the application number is 201110460618.2. Although this patent simplifies the existing vehicle to a certain extent The structure of the luggage compartment door lock opening device makes it more convenient for users to use, but the actual mechanism used to open the luggage compartment door lock also includes a transmission mechanism and an opening mechanism. The opening mechanism includes a conversion slide plate, a shift fork, and a connecting piece , transmission parts, lock cylinder assembly and cylinder. The transmission mechanism includes a main gear and a secondary gear. Therefore, if the user wants to open the luggage compartment door lock, he needs to unlock it through the cylinder first, and then drive other parts in the opening mechanism to move accordingly, and finally drive the main gear. The gear and pinion rotate to unlock the luggage compartment door lock. This structure still has defects such as many transmission parts and complex structure.
