Description

Roof turning device and vehicle with same

Technical Field

The invention relates to the field of automobiles, in particular to a car roof turnover device applied to an open sports car.

Background

With the progress of society and rapid economic development, people pursue the quality of life to be gradually improved, and more open sports cars appear in daily life. In order to meet the requirements of all weather, the roof of the convertible sports car basically has the sealing performance of the roof of the car in the unfolded state, and the roof of the convertible sports car is safe and stable to open and close.

CN1293122A discloses a retractable hard roof for a vehicle, which comprises an upper roof part and a rear roof part, which are connected by a link assembly. When the roof is in the stowed position, the upper roof section can slide into the rear roof section and be stowed together in the receiving space behind the vehicle. This patent document does not relate to a sealing arrangement for a vehicle when the roof is closed and stowed.

CN2880565Y discloses a convertible hard top for a convertible vehicle, which comprises a base, a first link connected to the front end of the base, a second link connected to the rear end of the base, and a third link connected between the first link and the second link. The second connecting rod comprises a rear fixing rod and a front fixing rod connected with the rear fixing rod. In operation, each link is driven by the hydraulic cylinder to act, so that the roof part moves between a closing position for unfolding and closing the roof and a folding position for folding and folding the roof into the roof accommodating space. This patent document also does not relate to a sealing structure and therefore affects the aesthetic and aerodynamic performance of the vehicle when the roof is stowed or deployed.

CN1750952A discloses a retractable roof device and a vehicle equipped with such a device, which comprises a rear cover structure including a rear flip and side flips at both sides of the rear flip. The rear cover structure is movable to allow passage of the roof and its guides as the roof is moved between the deployed and stowed positions, and is capable of providing a sealing arrangement for the vehicle when in either the deployed or stowed positions following movement of the roof. In this patent document, the rear cover structure is interlocked with the movement of the roof. Specifically, when the roof moves, a swing arm poking rod extending from the main swing arm pokes a cam on the main shaft to rotate, and the rear turnover cover is driven to move through the L-shaped operating rod. When the main swing arm moves to a certain position, the swing arm poke rod interferes with the wire drawing pulley sleeved on the main shaft to drive the wire drawing pulley to rotate, the wire drawing pulley pulls a wire drawing, the other end of the wire drawing pulls the rotary shaft sleeve to rotate, and then the flip covers on the two sides are driven to be opened and closed. The structure is easy to cause the phenomena of inconsistent movement starting points of all parts and wire drawing derailment, thereby causing a series of destructive results, such as breakage of the rear flip cover, incapability of continuing movement of the vehicle roof due to pause and the like, and the complexity of the structure puts higher requirements on the precision of processing and assembly.

Detailed Description

The following detailed description of embodiments of the invention refers to the accompanying drawings.

Fig. 1 is a schematic perspective view of a roof drive mechanism 10 according to an embodiment of the present invention. Fig. 2 is a side view of the roof drive mechanism 10 shown in fig. 1. Fig. 3 is a side view of the roof drive mechanism 10 shown in fig. 1, showing the base 1.

As shown in fig. 1 to 3, the roof driving mechanism 10 mainly includes a base 1, a hydraulic cylinder 2, a guide rod 3, a connecting rod 4, a main swing arm 5, a front rod 6, a rear rod 7, and a main shaft 8. Wherein,

before describing the structure of the roof drive mechanism 10 in detail, for the convenience of description, the position near the hydraulic cylinder 2 or its piston rod is defined as "near" and vice versa as "far".

The hydraulic cylinder 2 is mounted on the base 1. The piston rod of the hydraulic cylinder 2 is hinged with the near end of the guide rod 3 and the near end of the connecting rod 4. The far end of the guide rod 3 is hinged on the base 1 and plays a role in guiding the movement of the piston rod of the hydraulic cylinder 2. The far end of the connecting rod 4 is hinged on the main swing arm 5, and the hinged position is close to the near end of the main swing arm 5. The near end of the main swing arm 5 is hinged on the main shaft 8. The main shaft 8 is mounted on the base 1. Therefore, when the piston rod of the hydraulic cylinder 2 extends, the main swing arm 5 can be driven to rotate around the main shaft 8 through the connecting rod 4.

The far end of the main swing arm 5 is hinged with the far end of the front rod 6, the near end of the front rod 6 is hinged with the far end of the rear rod 7, and the near end of the rear rod 7 is hinged on the base 1. It can be seen that the base 1, the main swing arm 5, the front rod 6 and the rear rod 7 form a four-bar linkage. As mentioned above, when the hydraulic cylinder 2 drives the main swing arm 5 to rotate, the main swing arm 5 drives the four-bar linkage to move, so as to unfold or close the roof.

The roof (not shown) of the vehicle has a closed position and a stowed position and is moveable between these two positions by a roof turnover mechanism, i.e. the four-bar linkage mechanism described above. The roof of the present invention may take a known configuration. For example, the roof may comprise a roof panel and a rear window hinged to each other, the roof panel being secured by a front bar 6 and the rear window being secured by a rear bar 7.

The four-bar linkage is generally provided on both lateral sides of the vehicle, and adopts the same structure. The four-bar linkages on both sides may use one hydraulic cylinder 2, which is arranged between the four-bar linkages on both sides, or each four-bar linkage may use one hydraulic cylinder alone.

Referring to fig. 1, when the piston rod of the hydraulic cylinder 2 contracts, the main swing arm 5 is pulled by the connecting rod 4 to rotate clockwise, and the main swing arm 5 pushes the front rod 6 to the right side, and simultaneously causes the rear rod 7 to rotate clockwise, so that the roof can be moved from the closed state to the stowed state. Conversely, when the roof needs to move from the retracted state to the closed state, the piston rod of the hydraulic cylinder 2 extends to cause the main swing arm 5 to rotate anticlockwise.

The main shaft 8 is also provided with a cam 9 and an L-shaped rear flip cover connecting rod 11 connected with the cam 9. The cam 9 can rotate on the main shaft 8. The near end of the rear flip connecting rod 11 is hinged on the cam 9, and the far end thereof is mounted on the rear flip 21 to drive the rear flip to rotate. At the proximal end of the main swing arm 5 there is a transversely extending swing arm tap lever 12 which can be brought into contact with the cam 9 to tap the cam 9 to rotate on the main shaft 8. A cam return spring 13 is connected to the cam 9 to return the cam 9. When the roof driving mechanism 10 drives the roof to move, the rear flip cover 21 can be linked through the cam 9 on the main shaft 8 and the rear flip cover connecting rod 11. That is, during movement of the roof, the rear flap 21 may be moved from the horizontal position to the vertical position so that the roof can be smoothly moved between the closed position and the stowed position. When the vehicle roof is in the closed position or the stowed position after the movement is finished, the rear flip cover 21 may be returned to the horizontal position by the elastic return action of the cam return spring 13, thereby providing a sealing structure for the vehicle.

Typically, the roof receiving space is a trunk having a trunk lid. The trunk lid can be opened from the front to the rear to accommodate the roof of the vehicle into the trunk. The trunk lid may also be opened from the rear to the front as in a conventional trunk lid for storing articles in the trunk.

In order to link the operation of the trunk lid with the operation of the rear lid 21, a wire drawing pulley 14 may be provided which cooperates with the cam 9 on the main shaft 8. Specifically, when the trunk lid is opened, the wire drawing pulley 14 can be rotated by the wire drawing. The wire drawing pulley 14 is engaged with the cam 9 to hold the cam 9 at a certain position so that the rear flap 21 is held at the open position by the rear flap link 11, thereby ensuring smooth storage of the roof of the vehicle in the trunk. The drawing pulley 14 may have a drawing pulley return spring 15 so that when the trunk lid is closed, the drawing pulley 14 may be returned to be disengaged from the cam 9 by the return spring 15, and the cam 9 may be returned by the elastic force of its return spring 13 to return the rear lid 21.

Fig. 4 is a schematic perspective view of the rear cover structure 20 according to an embodiment of the present invention, with the side flaps 22 in the deployed position. Fig. 5 is a schematic perspective view of the rear cover structure 20 shown in fig. 4 with the side flaps 22 in the stowed position.

As shown in fig. 4 and 5, according to one embodiment, the rear cover structure 20 mainly includes a rear folder 21, a side flip 22, a mounting plate 23, a driving motor 24, a wire 25, a rotation bushing 26, and a connecting arm 27. As shown in fig. 4, the side flaps 22 are on both sides of the rear flap 21 and are substantially flush therewith to provide a sealing structure for the vehicle. As shown in fig. 5, the side flip 22 is retracted to a position below the rear flip 21, and provides a space for the roof driving mechanism 10 to smoothly close or retract the roof.

Specifically, the driving motor 24 is mounted on the mounting plate 23, the rotation boss 26 is mounted on the rear folder 21, and the connecting arm 27 is used to connect the rotation boss 26 and the side folder 22. The drive motor 24 may pull the pull wire 25 in a variety of ways. In one embodiment, the shaft of the driving motor 24 can drive the gear to rotate, and the gear can be engaged with the flexible shaft with teeth to drive the flexible shaft to reciprocate. The flexible shaft can be connected with the sliding block, the sliding block can slide in the sliding groove, and the other end of the sliding block can be connected with the drawn wire, so that the flexible shaft drives the sliding block to slide in the sliding groove, and the drawn wire can be smoothly pulled. When the driving motor 24 pulls the wire 25, the wire 25 drives the rotating shaft sleeve 26 fixed on the rear flip 21 to rotate, the rotating shaft sleeve 26 drives the connecting arm 27 to rotate, and the connecting arm 27 drives the side flip 22 to rotate. Meanwhile, since the rotation boss 26 is preferably screw-mounted on the rear folder 21, the rotation boss 26 will also axially move with respect to the rear folder 21 while rotating, thereby causing the connection arm 27 and the side folder 22 to simultaneously rotate and axially move with respect to the rear folder 21. That is, the side flip 22 is simultaneously axially moved and rotated with respect to the rear flip 21 during the drawing of the drawing wire 25 by the driving motor 24, thereby being movable between the deployed position at both sides of the rear flip 21 and the stowed position under the rear flip 21. The movement mode and the transmission mechanism of the side flip 22 between the extended position at the two sides of the rear flip 21 and the retracted position under the rear flip 21 may also adopt other means, for example, the side flip 22 may also move axially for a distance relative to the rear flip 21 and then rotate; or directly via a linkage mechanism, as the present invention is not limited in this regard. The side flap 22 may be returned by providing a return spring in the swivel boss 26, i.e., from the deployed position shown in fig. 4 to the stowed position shown in fig. 5. The reset of the side flip 22 can also be achieved by the reverse rotation of the driving motor 24.

It can be seen that, in the present invention, the operation of the side flip 22 is not linked by the operation of the roof turnover mechanism 10, but a separate side flip driving mechanism is provided for driving the operation of the side flip 22.

The operation of the roof turnover device of the present invention will be explained below.

The movement process of folding and retracting the roof of the vehicle from the closed state into the trunk is as follows:

the trunk lid is opened from front to back, and meanwhile, the drawn wires on the trunk lid are driven to be slowly tightened.

The pressure in the hydraulic cylinder 2 is reduced, the piston rod of the hydraulic cylinder retracts into the hydraulic cylinder 2, under the guiding action of the guide rod 3, the main swing arm 5 is driven by the connecting rod 4 to rotate towards the rear of the vehicle, and the front rod 6 and the rear rod 7 of the vehicle roof are driven by the main swing arm 5 to move backwards, so that the vehicle roof of the vehicle starts to fold backwards.

When the main swing arm 5 rotates to a certain position around the main shaft 8, the swing arm poke rod 12 extending from the main swing arm 5 contacts with the cam 9 and drives the cam 9 to rotate on the main shaft 8, so that the rear flip cover 21 is driven by the rear flip cover connecting rod 11 to move from the approximately horizontal position to the vertical position, and the roof of the vehicle can pass through smoothly.

Along with the wire drawing on the luggage-boot lid gradually tightens up, after the luggage-boot lid was opened certain angle, the wire drawing will drive wire drawing pulley 14 and rotate, and wire drawing pulley reset spring 15 on the wire drawing pulley 14 is compressed the energy storage. As the rear flap 21 approaches the vertical position, the wire drawing slide 14 will contact and hold the cam 9 stationary, thereby holding the rear flap 21 in the vertical position.

During movement of the roof, the drive motor 24 in the side-flip drive mechanism is operated. The drive motor 24 will rotate the rotary sleeve 26 via the pull wire 25. During rotation of the swivel housing 26, the link arm 27 will cause the side flap 22 to rotate and move axially relative to the rear flap 21 to move from the extended position at the side of the rear flap 21 to the stowed position below the rear flap 21, thereby allowing the four-bar linkage to pass through.

After the roof of the vehicle is accommodated in the trunk through the four-bar linkage, the driving motor 24 stops operating, and the side flip 22 is returned to its deployed position by the elastic force of its return spring. At the same time, the trunk lid is closed, and the wire drawing pulley 14 is restored by the elastic force of its restoring spring 15 to be disengaged from the cam 9. The cam 9 will, through the action of its return spring 13, return the rear flap 21 to the horizontal position through the rear flap connecting rod 11, thus closing the trunk lid.

The operation of the vehicle roof from the stowed condition to the closed condition is substantially the reverse of the above-described operation and will not be described in detail.

While the invention has been described in detail with reference to specific embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
