Detailed Description

The utility model is described in more detail below with reference to the accompanying drawings.

Fig. 1 shows a plan view of a vehicle door inspection apparatus according to a first embodiment of the present invention, fig. 2 shows a side view of the vehicle door inspection apparatus according to the first embodiment of the present invention, and fig. 3 shows a rear view of the vehicle door inspection apparatus according to the first embodiment of the present invention. The side and rear views referred to in this invention are relative to the direction of travel of the vehicle.

As shown in fig. 1, the vehicle door inspection device includes a first limit wheel 1, a second limit wheel 2, and a wheel support frame 3 for supporting the first limit wheel 1 and the second limit wheel 2. The wheel support 3 is fixed in place in an automatic production line of a motor vehicle, for example to the floor or wall beside the production line. The distance between the first limit wheel 1 and the second limit wheel 2 and the vehicle body is set to be that at least one of the first limit wheel 1 and the second limit wheel 2 can contact with the vehicle door when the vehicle passes through. For example, the distance of the first spacing wheel 1 from the vehicle body is set to be greater than the distance of the second spacing wheel 2 from the vehicle body, for example, the distance L1 (shown in fig. 4) of the center of the first spacing wheel from the vehicle body is set to be about 420mm to 470mm, preferably 420mm, for example, and the distance L2 (shown in fig. 4) of the center of the second spacing wheel from the vehicle body is set to be about 150mm to 200mm, preferably 150mm, for example. When the doors of any type of vehicle passing through the exits of the workshops of the production line are not completely closed, the first and second stopping wheels 1 and 2 cooperate with each other to help the doors of all different types of vehicles to be automatically and completely closed.

In general, a vehicle has a front door 10 and a rear door 11 that are not uniform in length, and for a longer front door 10, the first stopper wheel 1 is pushed by friction between the front door 10 and the first stopper wheel 1, so that the front door 10 is closed to a corresponding angle, for example, an angle from 45 degrees to 20 degrees. As the vehicle advances, the second stopper wheel 2 comes into contact with the front door 10, and the second stopper wheel 2 is pushed by the frictional force between the front door 10 and the second stopper wheel 2, so that the door is completely closed. For a shorter rear door 11, the rear door 11 can be completely closed only by frictional contact between the second stopping wheel 2 and the rear door 11, while the first stopping wheel 1 does not contact the rear door 11. Adopt first spacing wheel 1 and second spacing wheel 2, avoided because the door is not closed completely and damages the risk of door and automobile body.

As shown in fig. 2 and 3, the vehicle door inspection apparatus according to the first embodiment of the present invention further includes a first sensor strip 4 located below the first spacing wheel 1, a first sensor 6 disposed opposite to the first sensor strip 4, and a first sensor support 7 for supporting the first sensor 6, and a second sensor strip 5 located below the second spacing wheel 2, a second sensor 8 disposed opposite to the second sensor strip 5, and a second sensor support 9 for supporting the second sensor 8. When the vehicle door is not normally closed due to an abnormal state, the vehicle door contacts the first limiting wheel 1 or the second limiting wheel 2, and the friction force between the vehicle door and the first limiting wheel 1 or the second limiting wheel 2 enables the first limiting wheel 1 or the second limiting wheel 2 to rotate. When the first limiting wheel 1 or the second limiting wheel 2 rotates, the first induction bar 4 or the second induction bar 5 is separated from the corresponding first sensor 6 or the second sensor 8. When the signals of the first sensor 6 or the second sensor 8 disappear, an alarm (not shown) connected with the first sensor 6 or the second sensor 8 sends out a vehicle transmission emergency stop alarm, the vehicle emergently stops, related personnel wait for checking and processing the vehicle door, the first limiting wheel 1 and the second limiting wheel 2 are recovered after the fault is eliminated, the alarm is reset, the vehicle continues to move forwards, and the production is recovered.

In an embodiment of the present invention, first sensor 6 and second sensor 8 may be, for example, proximity sensors, and first sensor strip 4 and second sensor strip 5 may be, for example, metal sensor strips.

Fig. 4 shows a schematic view of the door check device according to the first embodiment of the present invention in an operating state. As shown in fig. 4, the door check device is disposed on both sides of the vehicle body in the lateral direction of the vehicle. The radii of the first and second wheels 1, 2 may be set as appropriate, for example, to about 100mm to 150mm, with a radius of 100mm being preferred. If the door of the traveling vehicle is not completely closed, the first and/or second stopping wheels 1 and 2 of the door check device are/is activated so that the door can be automatically and completely closed.

In the above embodiment, the first limiting wheel 1 and the second limiting wheel 2 of the utility model can adopt mechanical thumb wheels, and the structure is simple and reliable.

The door check device also comprises an information collector used for recording relevant information of the alarm vehicle, and the information collector is connected with the corresponding sensor. When the corresponding sensors are started, the information collector records data and carries out information statistics, and a user can inquire the number of alarms, the type of the vehicle and the information of the vehicle, so that problems can be found and analyzed conveniently.

In order to prevent damage to the door when the vehicle is transported at too high a speed, the first and second stopping wheels 1, 2 are made of a cushioning material and are preferably wrapped, for example, with a foamed sponge to avoid wear to the door.

The embodiment of the vehicle door inspection device shown in fig. 1-4 is merely exemplary, and one skilled in the art can set the number of the check wheels as desired. Under the condition that the vehicle type of the production line vehicle is single, the limiting wheels can be arranged to be one according to the condition. Under the condition that the production line vehicle type is complicated, the number of the limiting wheels can be set to be three or more.

The vehicle door inspection device has simple structure and high reliability. By adopting the vehicle door inspection device, the vehicle doors of the vehicles on the production line can be automatically closed, so that the time for manual inspection prompt is saved. And under the condition of adopting more than two limiting wheels, all types of vehicle doors on the production line of multi-vehicle type mixed production can be automatically closed. And the vehicle door inspection device has the functions of alarming and prompting manual inspection, thereby improving the processing efficiency. The information collection system can record data and carry out information statistics, and is convenient for finding and analyzing problems. The vehicle door inspection device provided by the utility model eliminates the risk that the vehicle door is not closed, and avoids the problems of vehicle scrapping and production stop caused by the fact that the vehicle door is not closed.

The foregoing is illustrative of the present invention and is not to be construed as limiting thereof. Although exemplary embodiments of this invention have been described, those skilled in the art will readily appreciate that many modifications are possible in the exemplary embodiments without materially departing from the novel teachings and advantages of this invention. Accordingly, all such modifications are intended to be included within the scope of this invention.
