Description
Technical Field
The utility model relates to a device field of guard gate indicates a bus driver's seat is with guard gate especially.
Background
A bus, which refers to a motor vehicle that carries passengers traveling on an urban road along a fixed route with or without fixed shift time; with the progress of society, the requirements on the isolating door of the cab are higher and higher, and the semi-enclosed isolating door cannot meet the safety requirements; however, the adoption of the fully-enclosed isolating door easily causes that a driver cannot see the rearview mirrors on the two sides clearly so as to observe the driving road condition in real time.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a full surround and do not hinder a bus driver's seat of sight and use guard gate.
The technical scheme of the utility model as follows:
a protective door for a bus driver seat is characterized by comprising a protective door shell, wherein an arc-shaped groove is formed in the top surface of the protective door shell, a liftable transparent baffle is installed in the arc-shaped groove, and the transparent baffle is of an arc-shaped structure; and a lifting mechanism for driving the transparent baffle to lift is arranged in the protective door shell.
The lifting mechanism comprises an upright post, a rack, a movable plate and a driver; one end of the upright post is connected with the top surface of the inner cavity of the protective door shell, and the other end of the upright post is connected with the bottom surface of the inner cavity of the protective door shell; the rack is arranged on the side edge of one side of the upright post; the top of the movable plate is connected with the transparent baffle, and a driver is arranged on the movable plate below the transparent baffle. The driver is arranged to drive the movable plate to do up-and-down reciprocating motion, and the movable plate is connected with the transparent baffle, so that the transparent baffle can be driven to do up-and-down reciprocating motion together in the up-and-down reciprocating motion process of the movable plate, and the lifting of the transparent baffle is realized.
The driver comprises a worm gear box and a motor which are arranged on the moving plate; a driving shaft of the motor is connected with the input end of the worm gear box, and a driving gear is sleeved on the output shaft of the worm gear box; the driving gear is meshed with the rack. The driving gear on the worm gear box is driven to rotate by the motor, and the rack is fixed due to the fact that the driving gear is meshed with the rack, so that the moving plate can reciprocate up and down along the rack.
Four supporting columns are arranged on the moving plate at positions corresponding to the worm gear box, and screw holes are formed in the supporting columns; the four support columns enclose a quadrangle. Through setting up screw on support column and the support column so that install the worm gear case, because the support column has certain height, when the worm gear case was installed on it, can make drive gear just in time with rack toothing like this.
And a plurality of air holes are uniformly distributed in the middle of the transparent baffle. Through setting up the bleeder vent, on the one hand can increase gaseous circulation, and on the other hand because transparent baffle is the arc structure, the bleeder vent will distribute in curved department of buckling when distributing, can reduce the reflection of light condition greatly for the driver field of vision is better.
The utility model has the advantages that: due to the adoption of the transparent baffle plate with the arc-shaped structure and the arc-shaped open groove, the arc-shaped structure can greatly reduce the light reflection, and the problem that a driver cannot see clearly due to the light reflection of the transparent baffle plate when observing the rearview mirror is avoided; because still have elevating system in the guard gate casing and can drive transparent baffle and make up and down reciprocating motion in the arc fluting to realize packing up or opening of transparent baffle, the driver of being convenient for selects.
Drawings
The foregoing and other objects, features, and advantages of the invention will be apparent from the following detailed description taken in conjunction with the accompanying drawings.
Wherein: FIG. 1 is a schematic structural view of the present invention;
in the attached drawing, 1 is a protective door shell, 3 is a transparent baffle, 4 is a stand column, 5 is a rack, 6 is a moving plate, 7 is a driver, 8 is a worm gear box, 9 is a motor, 10 is a driving gear, 11 is a support column, and 12 is an air hole.
Detailed Description
Referring to fig. 1, the protective door for the bus driver seat is characterized by comprising a protective door shell 1, wherein an arc-shaped open slot is formed in the top surface of the protective door shell, a liftable transparent baffle 3 is installed in the arc-shaped open slot, and the transparent baffle is of an arc-shaped structure; and a lifting mechanism for driving the transparent baffle to lift is arranged in the protective door shell. Due to the adoption of the transparent baffle plate with the arc-shaped structure and the arc-shaped open groove, the arc-shaped structure can greatly reduce the light reflection, and the problem that a driver cannot see clearly due to the light reflection of the transparent baffle plate when observing the rearview mirror is avoided; because still have elevating system in the guard gate casing and can drive transparent baffle and make up and down reciprocating motion in the arc fluting to realize packing up or opening of transparent baffle, the driver of being convenient for selects.
The lifting mechanism comprises a vertical column 4, a rack 5, a moving plate 6 and a driver 7; one end of the upright post is connected with the top surface of the inner cavity of the protective door shell, and the other end of the upright post is connected with the bottom surface of the inner cavity of the protective door shell; the rack is arranged on the side edge of one side of the upright post; the top of the movable plate is connected with the transparent baffle, and a driver is arranged on the movable plate below the transparent baffle. The driver is arranged to drive the movable plate to do up-and-down reciprocating motion, and the movable plate is connected with the transparent baffle, so that the transparent baffle can be driven to do up-and-down reciprocating motion together in the up-and-down reciprocating motion process of the movable plate, and the lifting of the transparent baffle is realized.
The driver comprises a worm gear box 8 and a motor 9 which are arranged on the moving plate; a driving shaft of the motor is connected with the input end of the worm gear box, and a driving gear 10 is sleeved on the output shaft of the worm gear box; the driving gear is meshed with the rack. The driving gear on the worm gear box is driven to rotate by the motor, and the rack is fixed because the driving gear is meshed with the rack, so that the moving plate can reciprocate up and down along the rack; the specific structure of the worm gear box is described in detail in patent document No. 201510136521.4, and will not be described in detail here.
