Description
Technical Field
The invention belongs to the technical field of buses, and particularly relates to a bus driver door positioning buffer structure.
Background
Because the bus receives the infringement of other passengers and takes place occasionally with the interference at operation in-process driver, can lead to the emergence of malignant accident when serious, for the guarantee driver drives the in-process and does not receive external aggression, avoids the emergence of malignant accident, among the prior art, some buses have installed isolation protector in bus driving area, isolation protector includes fixed wall and the driver's door that is used for the driver to come in and go out. In the aspect of the driver door, the driver door is hinged on the surrounding partition by a hinge in the prior art, a lock for controlling the opening and the closing of the driver door is installed on the driver door adopting the hinge structure, the lock comprises a lock body which is installed on the driver door and is provided with a telescopic spring bolt and a lock hole which is installed on the surrounding partition, when the driver door is closed, the spring bolt extends into the lock hole to prevent the driver door from being opened, when the driver door is opened, the spring bolt withdraws from the lock hole, the driver door can be opened, in order to ensure that the spring bolt can smoothly extend into and withdraw from the lock hole, a sufficient gap must be left between the spring bolt and the lock hole, because of the existence of the gap, when a vehicle runs, the driver door generates forced vibration along with the jolt of the vehicle and the vibration of parts such as an engine, impact is generated between the spring bolt and the lock hole, and noise is generated, and the noise interferes with the driver, the attention of the driver is dispersed, so that the safe running of the vehicle is influenced; in order to alleviate the problem, in the prior art, there is a technical scheme that a buffer strip made of a high polymer elastic material and having a rectangular or circular arc-shaped cross section is mounted on a driver door, when the driver door is closed, the buffer strip is compressed, the driver door has a tendency of opening towards the outside under the action of the elastic force of the buffer strip, and a lock tongue is pressed on one side of a lock hole to prevent impact between the lock tongue and the lock hole and noise generated thereby; when the compression amount of the buffer strip is small, the pressure between the lock tongue and the lock hole is small, the suppression effect on the impact between the lock tongue and the lock hole is small, the noise prevention effect is small, and the noise reduction effect is not achieved. Therefore, it is necessary to design a bus driver door positioning buffer structure which can improve the suppression effect on the vibration impact between the lock tongue and the lock hole, play a role in reducing noise, and does not increase the operating force for closing the driver door and influence the flexibility of the driver door operation. In addition, the positioning of the prior art driver door depends on the lock, a larger fit clearance cannot be left between the lock hole and the lock tongue, otherwise, larger noise is generated,
the utility model discloses a utility model with application number CN201520426820.7 discloses a hoist driver's cabin, this utility model is provided with the lug in the right part below of hanging in midair the frame, and the upside of lug is provided with rubber buffer block, realizes the buffering to hanging in midair the frame through rubber buffer block. However, this utility model rubber buffer block be a solid buffer block, only can provide outside pressure, can not provide the pulling force to the inboard, unsuitable bus driver's door location buffering.
The utility model discloses a silence cabinet door that shocks resistance, its technical scheme main points are provided with the buffering strip at cabinet door body inside wall, but the buffering strip is cyclic annular setting and butt in cabinet body surface, the buffering strip is the cavity setting, the confession has been seted up to cabinet door body inside wall the groove is established in the inlaying that the buffering strip inlayed, buffering strip part suddenly in cabinet door body inner wall, this utility model plays the silence effect through the buffering strip, makes simultaneously to have the buffering between cabinet door body and the cabinet body. However, the utility model can only provide pressure by the elasticity of the rubber, and can not provide holding force for the door, according to the specification, the utility model provides inward holding force between the door and the door frame by the magnetism of the buffer strip, which requires the door frame to be made of ferromagnetic material or to be embedded with ferromagnetic material, and the door frame commonly used for the existing bus driver door are made of aluminum alloy, so that the weight or the structural complexity of the door frame is increased, and the requirement of light weight of the bus is not met; in addition, as shown in the attached drawings, the utility model discloses the buffering strip is closed rectangle ring-shaped and sets up the butt in cabinet body surface, and the protruding function of its four sides side is only in order to increase the firm degree of assembly of buffering strip, does not help to buffering atress and location.
