Abstract

The utility model discloses an opening-controllable double-shaft hinge for a lateral door of a bus. The opening-controllable double-shaft hinge is characterized in that a double-shaft hinge comprises an L-shaped upper fixing support base for connecting a bus body and an L-shaped lower fixing support base for connecting the lateral door, wherein the L-shaped upper fixing support base and the L-shaped lower fixing support base are hinged with two ends of a U-shaped transition rotating bracket through an upper pin shaft and a lower pin shaft. The opening-controllable double-shaft hinge can meet the technical demand on large opening degree (generally being 160 degrees) of the lateral door of a new energy vehicle body and has the characteristics of small occupied space, big bearing capacity, low cost, long service life and convenience in mounting of the hinge.

Description

The controlled biaxial hinge of a kind of bus side chamber door aperture

Technical field

The utility model relates to a kind of bus box door hinges, the controlled biaxial hinge of especially a kind of bus side chamber door aperture.

Background technology

The hinge of new forms of energy car offside chamber door has following several requirement: 1) owing to the discharge bottle, in the side case try one's best greatly in the space, and hinge can not take too much space; 2) the side chamber door is opened frequently, and Men Tida is relatively heavy, so hinge must be durable in use; 3) owing to picking and placeing the requirement of storage battery convenience, door body aperture must be large, is not less than 150 degree; 4) after storage battery damages in the battery box in the gas with acid position, be easy to corrode rubber; 5) storage battery the temperature inside the box is higher, and rubber is relatively easily aging.

The side chamber door of new forms of energy car mostly uses the rubber adhesive tape in the market, former biaxial hinge exterior skin place need to increase the compensation angle bar, and skin easily causes to coat with lacquer with the hinge collision and splits, and body inner side need to increase the mouth of stepping down, integral body is not attractive in appearance, and actual operability is complicated.And owing to not considering spacing position, can only be the dimensional accuracy assurance opening angle relative position by fixing seat of hinge and hinge itself, cause the processing and manufacturing difficulty of hinge own large.

The utility model content

The technical problems to be solved in the utility model provides the controlled biaxial hinge of a kind of bus side chamber door aperture, satisfies the large aperture of new forms of energy car side chamber door (generally greater than 160 degree), and the processing and fabricating of hinge own is easy, and is with low cost, and the requirements such as convenient are installed.

For solving the problems of the technologies described above, technical solution adopted in the utility model is: the controlled biaxial hinge of a kind of bus side chamber door aperture, it is characterized in that: biaxial hinge comprises the L shaped upper fixed bearing that connects vehicle body, the L shaped lower fixed bearing of connection side chamber door, and upper fixed bearing and lower fixed bearing are hinged by the two ends of upper pin and lower bearing pin and U-shaped transition runing rest respectively.

Wherein, be provided with journey limited block last time between fixed bearing and the transition runing rest, be provided with next time journey limited block between lower fixed bearing and the transition runing rest.

Wherein, the fixed bearing is provided with the angle limited block; On the angle limited block is located at the side chamber door when the opening position corresponding with the transition runing rest.

Wherein, described last time, the journey limited block was located on the fixed bearing.

Wherein, described next time journey limited block is located on the transition runing rest.

The beneficial effect that adopts technique scheme to produce is: biaxial hinge of the present utility model is exclusively used in the new forms of energy car.The biaxial hinge top layer is zinc-plated, and is anticorrosion; Increase angle limited block and two backhaul limited blocks, any angle of door body aperture between 0-165 degree during use at biaxial hinge; The spacing position of angle can be adjusted according to the actual requirements, can increase in use according to the actual requirements or changes the spacing position of angle, avoids idle stroke in the situation that meet the demands, and can prevent from interfering with side skin; Owing to increasing angle limited block and backhaul limited block, the utility model is in the situation that satisfied instructions for use relative reduce difficulty of processing and assembly technology.In a word, the utility model can satisfy the technical requirements of the large aperture of new forms of energy body side chamber door (general〉160 degree), has to take up room littlely, and bearing capacity is large, and is with low cost, long service life, and hinge is installed easily characteristics.

Description of drawings

Fig. 1 is perspective view of the present utility model;

Fig. 2 is vehicle body assembling drawing of the present utility model;

Among the figure, 1, upper fixed bearing, 2, lower fixed bearing, 3, the transition runing rest, 4, upper pin, 5, lower bearing pin, 6, last time the journey limited block, 7, journey limited block next time, 8, the angle limited block, 9, body frame, 10, the side chamber door.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

As shown in Figure 1, 2, the utility model is the controlled biaxial hinge of a kind of bus side chamber door aperture, comprise the L shaped upper fixed bearing 1 that is fixed on the body frame 9, the L shaped lower fixed bearing 2 that is fixedly connected with side chamber door 10, upper fixed bearing 1 and lower fixed bearing 2 are hinged with the two ends of U-shaped transition runing rest 3 by upper pin 4 and lower bearing pin 5 respectively; Be provided with journey limited block 6 last time between upper fixed bearing 1 and the transition runing rest 3, be provided with next time journey limited block 7 between lower fixed bearing 2 and the transition runing rest 3, wherein, last time, the journey limited block 6 was located on the fixed bearing 1, also can be located on the transition runing rest 3, journey limited block 7 is located on the transition runing rest 3 next time, also can be located on the lower fixed bearing 2; Also be provided with angle limited block 8 on the upper fixed bearing 1; On angle limited block 8 is located at the side chamber door when opening upper fixed bearing 1 and the transition runing rest 3 corresponding positions.

As shown in Figure 2, under the normal condition: side chamber door 10 is closed, and biaxial hinge itself is with two backhaul limited blocks 6 and 7, and therefore, the left side stops for body frame 9 during the Men Tixiang anticlockwise, and therefore the door body is motionless; Opening 0-75 degree: pull side chamber door door body handle, a door body is rotated counterclockwise, because the arm of force that the be bullied support force that supports and two bearing pins are subject to is in different size, upper pin 4 is done and rotated counterclockwise, and lower bearing pin 5 is subject to the up time needle force and does not rotate; Opening 75-165 degree: this moment, hand unclamped no longer reinforcing, and a door body only is subject to the effect of gas support force, and transition this moment runing rest 3 is subject to stopping of angle limited block 8, and upper pin 4 is rotated in place, therefore can only lower bearing pin 5 90-degree rotations.
