[0029] It should be noted that the following detailed description is exemplary and is intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present invention belongs.
[0030] Embodiment 1
[0031] In a typical implementation manner of the present invention, with reference to Figures 1-7As shown in the figure, a portable hatch structure for the front luggage compartment includes the hood 1 structure of the vehicle. The hood is provided with a rectangular opening communicating with the luggage compartment inside the vehicle body, and a pair of hatches are movably arranged at the rectangular opening. The hatches are driven by motors and can be opened and closed parallel to the left and right sides, eliminating the need to open the hood 1 structure and solving the problem of excessive space occupation when the current hood is opened.
[0032] As Figure 3 shown in the figure, mounting plates 5 are provided at the left and right sides of the bottom of the hood 1 near the opening. A first driving mechanism is provided on the mounting plate, and the output end of the first driving mechanism is connected to the hatch through a linkage mechanism 2. The first driving mechanism drives the hatch to rotate through the linkage mechanism 2 to realize the opening and closing of the hatch. The mounting plate 5 provides a mounting position for the first driving mechanism and is used to support the first driving mechanism.
[0033] As Figure 4 shown in the figure, the mounting plate 5 includes a main support plate for fixing to the bottom of the hood. A connecting plate is vertically provided at the bottom of the main support plate for mounting the first driving mechanism, and the first driving mechanism uses a first motor.
[0034] As Figure 4 described, the first motor 3 is installed on one side of the connecting plate. The connecting plate is provided with a through hole, and the output end of the first motor 3 can extend to the outside of the connecting plate through the through hole by means of a bevel gear set structure and is fixedly connected to the second connecting rod. The rotating shaft 31 on the bevel gear is in bearing fit with the through hole on the connecting plate.
[0035] In this embodiment, the axis of the first motor is arranged along the vehicle body width direction. In other examples, the first motor 3 is arranged along the vehicle body length direction, and the output shaft of the first motor 3 can be directly fixedly connected to the second connecting rod without using a bevel gear set for steering.
[0036] The linkage mechanism 2 includes a first connecting rod 21 and a second connecting rod 22 with one end hinged to the bottom of the hatch. The other end of the first connecting rod 21 is hinged to the main support plate of the mounting plate 5, and the other end of the second connecting rod 22 is connected to the output end of the first driving mechanism. The first motor drives the two hatches to open and close parallel to the two sides through the linkage mechanism 2.
[0037] The hatches in this embodiment include a first hatch 11 and a second hatch 12. The first hatch 11 and the second hatch 12 can seal the opening after being closed. Each hatch corresponds to a set of mounting plates 5, a set of first motors 3, and a set of linkage mechanisms.
[0038] Among them, each set of linkage mechanisms 2 includes a second connecting rod and two first connecting rods. The second connecting rod is located between the two first connecting rods, and the first connecting rod 21 and the second connecting rod 22 form a four-bar linkage structure.
[0039] Specifically, as Figure 4As shown, taking the first hatch 11 as an example, one end of two first linkages 21 is hinged to the bottom of the first hatch 11, and the X-direction positions of the hinge points are the same. The two first linkages are arranged in parallel, and the X-direction represents the vehicle body width direction. The other ends of the two first linkages 21 are hinged to the front end of the main support plate of the mounting plate 5.
[0040] One end of the second linkage 22 is hinged to the bottom of the first hatch 11, and the other end is fixedly connected to the output end of the first motor near the connecting plate. The hinge point of the second linkage 22 and the first hatch 11 is different from the hinge point of the first linkage 21, and the hinge point of the second linkage is at the rear. Figure 4 In the middle, a set distance is set for the second linkage to translate to the right as a whole, so that the working principle of the linkage mechanism is similar to that of a four-bar linkage structure. When the first motor drives the second linkage 22 to rotate, the two hatches can be opened and closed in parallel left and right, with a small opening space and no problems such as knocking.
[0041] As Figure 4 shown, both the first linkage 21 and the second linkage 22 are arc-shaped, and the specific shape is similar to the shape of the letter "J", so that after the hatch is opened, it can always ensure that when the two hatches are opened and closed, they maintain a motion posture parallel to the engine hood 1.
[0042] As Figure 4 and Figure 5 shown, two sets of limit blocks 7 are provided on the outer side of the connecting plate of the mounting plate 5. The limit blocks 7 are used to limit the movement position of the second linkage 22. The first driving mechanism is installed below the mounting plate, and the output end of the first driving mechanism is connected to the second linkage to drive the second linkage 22 to rotate. The second linkage 22 is arranged on the outer side of the mounting plate and in the same plane as the limit blocks. The motion limit when the hatch is opened and closed is the position where the second linkage 22 contacts the two limit blocks 7. When the second linkage 22 touches the preset limit block 7, the driving motor will automatically stop running. At this time, the hatch reaches its maximum opening angle and remains in a hovering state, ensuring that the user can safely and conveniently access the trunk space.
[0043] As Figure 6 shown, a circle of side water trough 9 is provided inside the rectangular opening of the engine hood 1, and a sealing strip 8 is provided inside the side water trough 9. The sealing strip 8 is used for sealing after the hatch is closed.
[0044] As Figure 4 shown, a middle water trough 6 is provided on the side of the first hatch 11 close to the second hatch 12. The cross-section of the middle water trough 6 is U-shaped. The middle water trough 6 is arranged along the front and rear directions of the vehicle body. The front and rear ends of the middle water trough 6 extend to the side water trough 9, and drain holes are provided on the side water trough 9, which can drain water in time to prevent water from entering the trunk.
[0045] As Figure 4As shown, locking plates are provided at the front and rear sides of the bottom of the hatch door, and pin holes are provided on the locking plates. A locking mechanism 4 is provided at the middle position near the front side and the rear side of the bottom of the engine hood opening for locking the hatch door after it is closed.
[0046] Specifically, the locking mechanism 4 includes a second driving mechanism and a bolt connected to the output end of the second driving mechanism. The second driving mechanism is a second motor. The output end of the second motor is connected to two bolts through a connecting rod. When the two hatch doors are closed, the two second motors drive the four bolts to insert into the pin holes to achieve the locking of the hatch door.
[0047] This embodiment further includes a controller provided on the vehicle body. The controller is connected to the first motor and the second motor and is configured with hatch door opening and closing buttons. When the opening button is pressed, the controller can control the second motor to first drive the bolt 41 to withdraw from the pin hole, and then control the first motor to rotate to realize the left and right parallel opening of the first hatch door 11 and the second hatch door 12. When the closing button is pressed, the controller first controls the first motor 3 to reverse to close the hatch door, and then controls the second motor to drive the bolt to lock the hatch door.
[0048] It can be understood that the closing button can be set at the bottom of the hatch door so that after putting items in the trunk, the hatch door can be directly closed through the closing button, and its working principle is similar to that of the closing button of the existing car trunk.
[0049] In this embodiment, the first hatch door 11 and the second hatch door 12 can be unfolded or closed in a posture of left and right parallel opening and closing when opening and closing, as Figure 2 shown. When the hatch door is opened, it will not occupy too much external space, solving the problem that there may be a collision with the front trunk lid when taking and placing goods in the current car trunk, and realizing the convenience of taking and placing goods and the convenience of opening and closing the trunk lid. In addition, through the integration of the four-bar linkage formed by the link mechanism 2 and the front trunk lid, the stability and reliability of the overall structure are enhanced.
[0050] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
