Abstract
The utility model provides an anti-clamping structure for a rear door of an automobile, which comprises a door plate and an automobile body, wherein the door plate is provided with a door plate concave positioning groove, a collision block is arranged in the door plate concave positioning groove, and the height of the collision block is not higher than the depth of the door plate concave positioning groove; the concave constant head tank of automobile body has been seted up to the relative position department of the concave constant head tank of automobile body and door plant, is provided with the buffer block in the concave constant head tank of automobile body, and the buffer block includes the rubber bag, and the rubber bag is loaded with non-Newtonian fluid material, and when door plant and automobile body separation, the degree of depth that highly is higher than the concave constant head tank of automobile body of buffer block when the door plant closes with the automobile body, the degree of depth that highly equals the concave constant head tank of automobile body of buffer block. The physical structure is used for replacing an electric structure to realize the hand clamping prevention function of the back tail door, the characteristics of high hardness of the non-Newtonian fluid during fast impact and low hardness during slow impact are utilized to limit the speed of the door plate during closing, and the phenomena of hand clamping prevention function failure caused by misjudgment of the sensor and the specific condition of opening and closing a system fault lamp are avoided.
Description
Technical Field
The utility model belongs to the technical field of automobile parts, and particularly relates to an anti-pinch structure of a rear tail door of an automobile.
Background
At present, whether there is the foreign matter between tail-gate and the automobile body after judging the car to the structure of car tail-gate anti-pinch design generally through infrared sensor, mechanical sensor etc, if there is the foreign matter then feedback signal gives anti-pinch device, the drive anti-pinch device starts, avoid unexpected injury, but above operation all can play a role when the sensor is effective, when sensor outage became invalid or other reasons became invalid, anti-pinch device can not start, consequently still exist under the special circumstances and is pressed from both sides the risk of hindering.
SUMMERY OF THE UTILITY MODEL
In order to solve the problems in the background art, the utility model provides an anti-pinch structure of a rear tail door of an automobile.
The technical scheme of the utility model is as follows:
an anti-pinch structure of a rear tail door of an automobile comprises a door plate and an automobile body, wherein a door plate concave positioning groove is formed in the door plate, a collision block is arranged in the door plate concave positioning groove, and the height of the collision block is not higher than the depth of the door plate concave positioning groove; the automobile body concave positioning groove is formed in the position, opposite to the door plate concave positioning groove, of the automobile body, a buffer block is arranged in the automobile body concave positioning groove and comprises a rubber bag, a non-Newtonian fluid material is loaded in the rubber bag, when the door plate is separated from the automobile body, the height of the buffer block is higher than the depth of the automobile body concave positioning groove, and when the door plate is closed to the automobile body, the height of the buffer block is equal to the depth of the automobile body concave positioning groove.
Preferably, the impact block and the door plate are integrally formed.
Preferably, the buffer block is bonded or screwed to the concave positioning groove of the vehicle body.
Preferably, an upper surface of the impact block is planar.
Preferably, the cushion block is formed in a mountain shape as a whole, and the cushion block and the striker block contact each other when the door panel and the vehicle body are closed.
The utility model has the following beneficial effects:
the utility model provides an automobile back door anti-pinch structure, which uses a physical structure to replace an electric structure to realize the anti-pinch function of the back door, utilizes the characteristics of high hardness of non-Newtonian fluid during fast impact and low hardness during slow impact to limit the closing speed of a door plate, improves the hardness of a buffer block due to the too high impact speed between the impact block and the buffer block when the door plate is closed fast, and cannot be closed normally.
