Description

TECHNICAL FIELD

This invention is relevant to automobile accessories, especially a hard flipping car cover.

BACKGROUND TECHNOLOGY

The cargo hopper of a pick-up truck (also known as a sedan truck) is used to carry goods, as long as it is open, in order to avoid the rain from wetting the goods inside the cargo hopper in rainy and snowy weather, a car cover is invented and installed on the cargo hopper of the pick-up truck, using the car cover to shelter the goods in the cargo hopper to avoid the goods inside from being wet by rain.

The existing car cover is erected at 90° and the supporting system is concentrated at the point of support, which makes the supporting system prone to damage.

Moreover, most existing covers require multiple rotating shaft, the car cover does not need to be fully opened in practice, the frequently used rotating shaft system is prone to damage if a lower cost rotating shaft system is used, while the usage of a higher cost rotating shaft result in a higher production cost of the entire car cover.

About the Invention

The purpose of the invention is to provide a car cover with multiple rotating shaft, make better stability of the supporting system as well as longer service life by improving the supporting system, secondly, the cost and service life of the different rotating shaft systems are used to make the car cover more economical.

By adjusting the position of the connecting arm, it is possible to control the rotation angle of the large front bar rotating shaft and thus the angle of rotation of the first plate body. As the plate body is able to turn 95°-110° when rotating, the plate body is not completely vertical when standing up but forms an obtuse angle of 95°-110° with the cargo hopper, so that the supporting base can be directly connected to the plate body and set parallel to it, whereas the existing plate body can only turn 90°, so that the supporting base needs to make an oblique angle of about 15° when it is connected to the plate body in order to facilitate the connection of the supporting pole, as the supporting pole is tilted to support the plate body after it is standing up, tilting the inclined plate by 15-25°, the supporting pole has a larger contact area between the nut and the inclined plate after it is connected to the inclined plate, the inclined plate is subjected to a more even force, which not only supports more stability but also extends the service life of the supporting block. the buffer plate can be in the form of a long strip or a plurality of blocks structures lined up in sequence in the structure.

The first plate body 5 is connected to the front bar system by the large front bar rotating shaft 1 by rotation, the first plate body 5 is connected to a second plate body 6 by a first rotating shaft system 2 by rotation.

The second plate body 2 is rotatably connected to the third plate body 7 by a second rotating shaft system 3.

The three-point positioning of the first plate body 5 is achieved by means of a large front bar rotating shaft 1, a buffer block 84 and a buffer plate 85. When the first plate body 5 is turned up, the upper end of the first plate body 5 rests on the buffer plate 85, while the first rotating shaft system 2 presses on the buffer block 84, at which point the angle between the plate body and the horizontal plane is greater than 90°, enabling the plate body to stand.

Embodiment 2

On the basis of embodiment 1, as shown in FIGS. 15-17, 20 and 21, the supporting system includes a supporting pole assembly and a large front bar rotating shaft 1.

The supporting pole assembly includes a supporting pole 81, a supporting pole head 82 and a supporting block 83.

The large front bar rotating shaft 1 not only drives the first plate body 5 to turn over, but also supports the first plate body 5 after rotation by using its hard connection structure.

When the car cover is closed, the first plate body 5 is in a horizontal state, at the same time the second limiting section 15 tightens the first limiting section 14 and limits the first limiting section 14, when the car cover is opened, the first plate body 5 is standing up, while the connection arm 13 is against the end of the top pillar 11, which supports the front bar rotating centre 12.

By adjusting the position of the connecting arm 13, it is possible to control the rotation angle of the large front bar rotating shaft 1 and thus the angle of rotation of the first plate body.

As the plate body is able to turn 95°-110° when rotating, the plate body is not completely vertical when standing up but forms an obtuse angle of 95°-110° with the cargo hopper, so that the supporting base 86 can be directly connected to the plate body and set parallel to it, whereas the existing plate body can only turn 90°, the supporting base 86 needs to make an oblique angle of about 15° while connecting to the plate body to facilitate the connection of the supporting pole 81.

In practice, it is necessary to connect a nut (not shown in the drawing) to the supporting pole 81 and use the nut to press against the tilt plate 832 to provide support.

As the supporting pole 81 is tilted to support the plate body after it is standing up, tilting the inclined plate 832 by 15-25°, the supporting pole 81 has a larger contact area between the nut and the inclined plate 832 after it is connected to the inclined plate 832, the inclined plate 832 is subjected to a more even force, which not only supports more stability but also extends the service life of the supporting block 83.

After the plate body is stood up, one second side bars 31 of the second rotating shaft system 3 is pressed against the buffer block 84, the other second side bar 31 of the second rotating shaft system 3 together with the second intermediate connection bar 33 are suspended.

The buffer block 84 includes a buffer pad 841 and a fixing pad 842, the fixing pad 842 is connected to the front bar system, the fixing pad 842 is provided with a socket 843, the buffer pad 841 is connected to the fixing pad 842, the buffer pad 841 is of an “L” shape, the buffer pad 841 is used to support the plate body, the “L” shape of the buffer pad 841 is made to hold the second rotating shaft system 3 in place and prevent it from sliding.
