[0030] Please refer to Figures 1 to 5 , Figure 1 This is a schematic structural diagram of a vehicle hood opening mechanism in one embodiment of the present invention; Figure 2 for Figure 1 A schematic structural diagram of the vehicle hood opening mechanism from another perspective; Figure 3 for Figure 1 A schematic diagram of the partial structure of the vehicle hood opening mechanism;

[0031] Figure 4 for Figure 1 A schematic diagram of a portion of the structure of the vehicle hood opening mechanism; Figure 5 for Figure 1 A schematic structural diagram of the vehicle hood opening mechanism from another angle is shown.

[0032] The present invention provides a vehicle comprising a vehicle body, a hood and a vehicle hood opening mechanism.

[0033] In the present invention, the hood is hinged to the vehicle body at one end closest to the cab, and the end remote from the cab is an opening end. The hood can be rotated relative to the hinged end to open the space covered by the hood upward or close the space covered by the hood downward. The hinged structure of the hood and the cab is not shown in the drawings herein, and those skilled in the art are referred to the existing art.

[0034] In the present invention, the hood and the vehicle body are locked by a two-stage lock. That is, the secondary lock needs to be opened step by step to open the hood. That is, during the hood opening process, the main lock 9 needs to be opened first, and then the secondary lock 8 needs to be opened to lock the hood and the vehicle body. This article defines the secondary lock as the main lock 9 and the secondary lock 8. In one example, the main lock 9 and the secondary lock 8 are not locked to the hood at the same time. The hood can be locked to the vehicle body through the main lock 9 and the secondary lock 8 respectively. When the hood is locked normally, the hood is locked to the vehicle body through the main lock 9, and the secondary lock 8 and the vehicle body temporarily do not have a locking effect. When the main lock 9 is opened, the secondary lock 8 and the vehicle body are locked during the hood opening process. Unlocking the secondary lock 8 and the vehicle body allows the hood to be opened. The vehicle hood opening mechanism of the present invention includes a vehicle logo 1 that is rotatably connected to the vehicle body, and a first connecting rod mechanism and a second connecting rod mechanism that are linked to the vehicle logo 1. The car logo 1 is usually set in the middle of the front end of the car body. The car logo 1 can be rotatably connected to the car body through a rotating shaft, and the rotating shafts of the two can be roughly parallel to the width direction of the vehicle.

[0035] In the present invention, when the car logo 1 rotates to the first position, the car logo 1 drives the main lock buckle 9 to the unlocked position with the hood through the first connecting rod mechanism. When the car logo 1 rotates to the second position, the car logo 1 drives the secondary lock buckle 8 to the unlocked position with the hood through the second connecting rod mechanism. The rotation direction of the car logo 1 can be in various forms. In a specific example, the car logo 1 can rotate downward (counterclockwise) around the rotation axis to achieve the main lock buckle 9 in the unlocked position, and the car logo 1 can rotate upward (clockwise) around the rotation axis to achieve the unlocking of the secondary lock buckle 8. Of course, the rotation direction of the car logo 1 is not limited to the above-mentioned one, and other forms are also possible as long as the above-mentioned technical effects can be achieved.

[0036] The present invention provides a vehicle logo 1 and a first connecting rod mechanism and a second connecting rod mechanism linked to the vehicle logo 1. The vehicle logo 1 rotates to drive the two connecting rod mechanisms to open the main lock buckle 9 and the auxiliary lock buckle 8 respectively. In this way, the operator only needs to open the hood at the same position, which can greatly improve the convenience of opening the vehicle hood, and indirectly improve the comfort of use of the entire vehicle, and is also conducive to optimizing the configuration of other components of the entire vehicle.

[0037] To improve the convenience of mechanism installation, in one embodiment, the vehicle hood opening mechanism may further include a first slide rail 21, a zipper block 10, and a first zipper 19. The first slide rail 21 is fixed to the vehicle body. The first slide rail primarily facilitates the arrangement of the zipper block 10 and the first zipper 19. The first slide rail may extend generally horizontally, but may also extend in other directions. One end of the first zipper 19 is fixedly connected to the zipper block 10, which is slidably disposed on the first slide rail 21. The zipper block 10 is connected to the free end of the last link of the first linkage mechanism. Driven by the first linkage mechanism, the zipper block 10 can slide along the first slide rail 21, thereby driving the first zipper 19 to pull the main lock buckle 9 out of the locked position.

[0038] Similarly, the vehicle hood opening mechanism can be further provided with a second zipper 20 and a second slide rail 22. One end of the second zipper 20 is connected to the secondary lock buckle 8, and the other end is connected to the secondary zipper block 23 that slides with the second slide rail 22. The secondary zipper block 23 is connected to the free end of the last link of the second linkage mechanism. Driven by the second linkage mechanism, the secondary zipper block 23 can slide along the second slide rail 22, thereby driving the second zipper 20 to pull the secondary lock buckle 8 out of the locked position.

[0039] In order to improve the flexibility of the main lock buckle 9 and the auxiliary lock buckle 8, the vehicle hood opening mechanism of the present invention also includes a first elastic component 17, which is used to provide a restoring force for the main lock buckle 9 to move to the locked position; that is, when the main lock buckle 9 is disengaged from the hood lock, and the opening end of the hood moves upward away from the locked position with the main lock buckle 9, under the action of the elastic force of the first elastic component 17, the main lock buckle 9 can automatically return to its original position, and at the same time push the first connecting rod mechanism and the vehicle logo 1 in the opposite direction to return to their original positions.

[0040] Similarly, the vehicle hood opening mechanism may also include a second elastic component 18 to provide a restoring force to the secondary lock catch 8 when it moves to the locked position. Specifically, when the secondary lock catch 8 is disengaged from the hood and the opening end of the hood moves upward, away from the locked position with the secondary lock catch 8, the elastic force of the second elastic component 18 automatically returns the secondary lock catch 8 to its original position, simultaneously pushing the second linkage mechanism and the vehicle logo 1 back to their original positions.

[0041] In the above embodiment, the first elastic component 17 and the second elastic component 18 may both be springs.

[0042] In order to prevent the dangerous situation of the hood being opened due to false triggering during driving, the present invention also makes the following arrangements for the vehicle hood opening mechanism.

[0043] The vehicle hood opening mechanism also includes a locking mechanism 16, which is used to limit the rotation of the car logo 1 relative to the rotation axis between it and the car body. When the car is in driving state, the locking mechanism locks the rotation axis of the car logo 1, so that the car logo 1 is in a fixed state and cannot rotate. When the car is in a parked state, the locking mechanism is in a closed state, and the car hood can be opened by pressing the car logo 1.

[0044] The locking or closing of the locking mechanism 16 can be achieved by a control component, which is used to control the locking mechanism 16 to selectively lock or unlock the rotation axis. The control component can be a vehicle controller of the vehicle, or it can be a separate controller. The state of the locking mechanism is controlled by vehicle operating parameters. For example, when the control component determines that the vehicle is moving based on the vehicle operating parameters, it controls the locking mechanism to lock the vehicle logo rotation axis 2. When the control component determines that the vehicle is stopped based on the vehicle operating parameters, it controls the locking mechanism to unlock the vehicle logo rotation axis 2, so that the vehicle logo 1 can rotate.

[0045] In the present invention, the main lock is hinged to the vehicle body, and the first connecting rod mechanism of the vehicle hood opening mechanism includes a first rod 15 and a second rod 11 hinged to each other. The other end of the first rod 15 is hinged to the back side of the vehicle logo 1, and the other end of the second rod 11 is hinged to the main lock to drive the main lock to rotate around its hinge point with the vehicle body.

[0046] To improve the flexibility of the mechanism, the first link mechanism further includes a first slider for slidingly cooperating with a first slideway 12 provided on the vehicle body and extending in a first direction. Both the adjacent ends of the first rod 15 and the second rod 11 are hinged to the first slider. The first direction may extend in the longitudinal direction.

[0047] The first slider can be a whole, of course, the first slider can also be a split structure, for example, the first slider includes a first sub-slider 14 and a second sub-slider 13, the adjacent ends of the first rod 15 and the second rod 11 are hinged to the first sub-slider 14 and the second sub-slider 13 respectively, the first sub-slider and the second sub-slider are both arranged inside the slide, and when the first sub-slider moves along the first slide 12, it can simultaneously drive the second sub-slider to move.

[0048] Similarly, the secondary lock buckle 8 is hinged to the vehicle body, and the second connecting rod mechanism includes a third rod 3 and a fourth rod 7 that are hinged to each other. The other end of the third rod 3 is hinged to the back side of the vehicle logo 1, and the other end of the fourth rod 7 is hinged to the secondary lock buckle to drive the secondary lock buckle to rotate around its hinge point with the vehicle body.

[0049] The second link mechanism further includes a second slider for slidingly cooperating with a second slideway 4 extending along the first direction provided on the vehicle body. The adjacent ends of the third rod 3 and the fourth rod 7 are both hinged to the second slider.

[0050] Similarly, the second slider can be a whole. Of course, the second slider can also be a split structure. For example, the second slider includes a third sub-slider 5 and a fourth sub-slider 6. The adjacent ends of the third rod 3 and the fourth rod 7 are hinged to the third sub-slider 5 and the fourth sub-slider 6 respectively. The third sub-slider 5 and the fourth sub-slider 6 are both arranged inside the second slide 4. When the third sub-slider 5 moves along the second slide 4, it can also drive the fourth sub-slider 6 to move.

[0051] In order to improve the flexibility of the mechanism, the second rod 11 can be further connected to the main lock buckle 9 through the zipper block 10.

[0052] To enhance the flexibility of the mechanism, the vehicle hood opening mechanism also includes an elastic device (not shown in the accompanying drawings) press-fitted between the hood and the vehicle body. This device applies a spring force to pull the hood opening end away from the vehicle body. This allows the elastic device to exert an upward force on the hood during opening. Once the primary latch 9 is unlocked from the hood, the elastic force of the elastic device automatically causes the hood to move upward, free of its locked position with the primary latch 9. Similarly, the elastic device acts similarly on the secondary latch 8.

[0053] The elastic device can be a spring, or other components.

[0054] The vehicle of the present invention has the above-mentioned vehicle hood opening mechanism, so the vehicle also has the above-mentioned technical effects of the vehicle hood opening mechanism.

[0055] The above is a detailed introduction to the hood opening mechanism and vehicle provided by the present invention. Specific examples are used herein to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only intended to help understand the method and core concept of the present invention. It should be pointed out that, for those skilled in the art, various improvements and modifications may be made to the present invention without departing from the principles of the present invention, and such improvements and modifications also fall within the scope of protection of the claims of the present invention.
