Abstract

The utility model relates to an electric apparatus for door pulling forward and backward of a coach, composed of a motor (1) and a speed changer (2). The utility model is characterized in that the speed changer (2) is fixedly connected with a buffer (6), the buffer (6) is movably connected with a reel (3) through a bearing (7), and the reel (3) is movably connected with a steel cable (4). So, the utility model has the advantages of convenient use, low labor intensity and reliable safety, and is especially suitable for pulling a door forward and backward in a bread taxi and other coaches.

Description

Sliding door automobile door electric device before and after the utility van

The utility model relates to a kind of electric device of arrangements for automotive doors, sliding door automobile door electric device before and after particularly a kind of utility van.

At present, the utility van that the utility van of domestic road running and car production producer produce, except the large and medium-sized utility van of part adopts the accordion door form, what other car adopted is the form of front and back sliding door, sliding door must be by manpower ability stretchy before and after these, the labour intensity height, and handle is all arranged with the innner and outer, must open door lock earlier when opening car door, could door be opened by handle, thereby use trouble, the particularly present domestic bread taxicar that travels, the driver can not control the passenger and get on and off, poor stability.

The purpose of this utility model will provide a kind of labour intensity low exactly, uses simply sliding door automobile door electric device before and after the utility van of high safety.

The purpose of this utility model is achieved in that utility van front and back sliding door automobile door electric device, by motor (1), change-speed box (2) is formed, it is characterized in that described change-speed box (2) and energy disperser (6) are for captiveing joint, energy disperser (6) flexibly connects by bearing (7) with reel (3), and reel (3) flexibly connects steel cable (4).

The stretching, extension of steel cable of the present utility model (4) is by fleet wheel I (8) and fleet wheel II (11), guiding principle rope pulley III (12) bonded assembly, carry out bonded assembly by nut I (5) between change-speed box (2) energy disperser (6), the cylindrical swivel of energy disperser (6), be connected with T shape leading screw (17) on the fleet wheel III (12), be connected with nut II (18) on the T shape leading screw (17), be connected with the travel switch (19) of control opening/closing door of vehicle degree on the nut II (18).

The utility model compared with prior art has the following advantages:

1, owing to adopt motor (1) to drive change-speed box (2), change-speed box (2) is connected with energy disperser (6), reel (3), guiding principle rope (4), do not need just can open car door with manpower, thereby labour intensity is low, uses simple.

2, owing to adopt electrically operated form, thereby the switch of car door is controlled in driver's hand, saved the inside and outside handle of car door, high safety.
