[0052] Such as Figure 1As shown in the figure, the present utility model provides an automobile, which includes: a vehicle body 1, a vehicle door 2, and an electric hybrid door opening mechanism. This door opening mechanism can drive the vehicle door 2 to open or close in a first driving mode, or to open or close in a second driving mode. Among them, the common point of the first driving mode and the second driving mode is that the vehicle door 2 is hinged to the vehicle body 1, and the difference lies in the different running trajectories of the vehicle door 2. By adopting this door opening mechanism, when the user opens the vehicle door 2, they can make a choice, which has stronger applicability and sensory experience.

[0053] The following will detail the electric hybrid door opening mechanism of the present application through the following embodiments.

[0054] Embodiment 1:

[0055] As Figures 1-8 shown, in this embodiment, the door opening mechanism includes: a first driving component 100, which is used to drive the vehicle door 2 to open or close it in a first driving mode, and is installed at the empty position below the left side of the A-pillar of the vehicle body 1; a second driving component 200, which is used to drive the vehicle door 2 to open or close it in a second driving mode, and is installed inside the vehicle door 2 and integrated with the vehicle door 2; and a switching component 300, which is used to switch between the first driving mode and the second driving mode when the vehicle door 2 is closed, so that the vehicle door 2 can only be opened and closed in one of the modes.

[0056] Among them, the first driving mode is that the vehicle door 2 rotates and opens or closes along a curve combining a horizontal plane and a vertical plane; the second driving mode is that the vehicle door 2 rotates and opens or closes along a horizontal plane.

[0057] In this technical solution, the movement trajectory of the vehicle door 2 when it opens in the first driving mode is a curve, such as a scissor door or a butterfly door; the movement trajectory of the vehicle door 2 when it opens in the second driving mode is an arc line, that is, a flat door. In order to use two types of hinges between the vehicle door 2 and the vehicle body 1, and to avoid movement interference between the first driving component 100 and the second driving component 200, a switching component 300 is also provided. Through the switching component 300, a vehicle door 2 can have two opening methods.

[0058] Embodiment 2:

[0059] This embodiment is a further improvement based on Embodiment 1.

[0060] As Figures 2-5 、 Figure 7 、 Figure 8As shown in the figure, in this embodiment, the door opening mechanism further includes: a door connecting arm 400, on which the door 2 is mounted; a rotating arm 500, which has a first connecting end 510 and a second connecting end 520, and the second connecting end 520 on the rotating arm 500 is hinged to the door connecting arm 400;

[0061] Among them, the first driving component 100 can drive the rotating arm 500 and the door connecting arm 400 to rotate around the first connecting end 510, so that the door 2 can be opened or closed in the first driving mode;

[0062] Or the second driving component 200 can drive the door connecting arm 400 to rotate around the second connecting end 520, so that the door 2 can be opened or closed in the second driving mode.

[0063] In this technical solution, more specifically, the first driving component 100 is used to be assembled on the vehicle body 1, and is fixedly connected to the vehicle body 1. The first driving component 100 is used to control the rotation of the rotating arm 500. The rotating arm 500 is rotatably connected to the door connecting arm 400, and the door connecting arm 400 is fixedly connected to the door 2; when the door 2 is opened or closed in the first driving mode, the rotating arm 500 rotates, while the door connecting arm 400 is locked on the rotating arm 500 and cannot rotate. Therefore, the door 2 is opened or closed in the scissor door / butterfly door movement mode; when the door 2 is opened or closed in the second driving mode, the rotating arm 500 is locked and cannot rotate, while the door connecting arm 400 can rotate on the rotating arm 500. Therefore, the door 2 is opened or closed in the swing door movement mode.

[0064] Specifically, a convex block 410 is provided on the door connecting arm 400, a slot 111 is provided on the vehicle body 1, and the switching component 300 is provided on the rotating arm 500;

[0065] The switching component 300 includes: a switching rod 310, which has at least one insertion portion 311 and a stop block 312; and a driving portion, which is used to drive the switching rod 310 to move linearly along its length direction, so that it presents a first state and a second state;

[0066] Among them, when the switching rod 310 is in the first state, the insertion portion 311 is inserted into the slot 111, the rotating arm 500 is locked, the door connecting arm 400 is opened, and the second driving component 200 is released from the restriction of the stop block 312 and can drive the door 2 to move; when the switching rod 310 is in the second state, the insertion portion 311 is disengaged from the slot 111, the convex block 410 abuts against the stop block 312, the door connecting arm 400 is restricted by the stop block 312 and is locked, the rotating arm 500 is opened, and the first driving component 100 is released from the restriction of the insertion portion 311 and can drive the door 2 to move.

[0067] In this technical solution, a strip-shaped installation chamber is further provided at a position of the rotating arm 500 close to its second connection end 520. The switching rod 310 is arranged in this installation chamber, and the switching rod 310 can only move along the length direction of the installation chamber. Therefore, the switching rod 310 and the rotating arm 500 are in a linkage state, and the rotation of the rotating arm 500 and the movement of the switching rod 310 are synchronized.

[0068] When the switching rod 310 is moved and the insertion portion 311 on the switching rod 310 is inserted into the slot 111, the switching rod 310 will be locked to the vehicle body 1, and the second connection end 520 on the rotating arm 500 will also be locked by the switching rod 310 at the same time. As a result, the rotating arm 500 cannot rotate around the first connection end 510, and the first driving mode of the vehicle door 2 is restricted. At the same time, the stopper 312 on the switching rod 310 slides out from the convex block 410 on the vehicle door connecting arm 400, that is to say, the vehicle door connecting arm 400 is released from the restriction of the stopper 312, and the second driving mode of the vehicle door 2 is started.

[0069] When the switching rod 310 is moved and the stopper 312 on the switching rod 310 abuts against the convex block 410 of the vehicle door connecting arm 400, the vehicle door connecting arm 400 cannot rotate along the second connection end 520, and the second driving mode of the vehicle door 2 is restricted. At the same time, the insertion portion 311 on the switching rod 310 disengages from the slot 111, and the switching rod 310 is released from the restriction of the vehicle body 1, that is, the rotating arm 500 is released from the restriction of the vehicle body 1. At this time, the rotating arm 500 can rotate around the first connection end 510 as the rotation point and drive the vehicle door connecting arm 400 to rotate, and the first driving mode of the vehicle door 2 is started.

[0070] Embodiment Three:

[0071] This embodiment is a further improvement based on any of the above embodiments.

[0072] As Figure 2 and Figure 5 shown, in this embodiment, the driving part includes: a rack 320, arranged on the switching rod 310 and disposed along its length direction; a gear 330, meshing with the rack 320; and a motor 340, used to drive the gear 330 to rotate so as to drive the rack 320 and the switching rod 310 to perform linear motion.

[0073] In this technical solution, the motor 340 drives the gear 330 to rotate, and then the rack 320 and the switching rod 310 connected thereto rotate. The structure is simple and the operation is convenient. It only needs to control the operating state of the motor 340.

[0074] In this embodiment, preferably, the motor 340 is arranged in parallel with the switching lever 310. This arrangement not only reduces the assembly volume of the driving part, but also avoids interfering with the movement of the door connecting arm 400.

[0075] Specifically, the driving part further includes: a worm 350 connected to the output shaft of the motor 340; a worm gear 360 meshing with the worm 350, and when the worm 350 rotates, the worm gear 360 moves along the length direction of the worm 350; wherein, a shaft 370 is further arranged on the worm 350, and the other end of the shaft 370 is connected to the gear 330.

[0076] In this technical solution, the motor 340 drives the worm 350 to rotate, thereby driving the worm gear 360 to rotate on the worm 350, and further driving the shaft 370 and the gear 330 to rotate, so as to realize the switching between the first mode and the second mode of the switching lever 310.

[0077] Embodiment Three:

[0078] This embodiment is a further improvement based on any of the above embodiments.

[0079] As Figure 2 Figure 5 shown, in this embodiment, specifically, the first driving assembly 100 includes: a mounting side plate 110 fixed to the vehicle body 1; and a first actuator arranged on the mounting side plate 110 for driving the rotating arm 500 to rotate; wherein, a slot 111 is located on the mounting side plate 110. By arranging the slot 111 on the mounting side plate 110, it is convenient for the overall assembly of the entire door opening mechanism.

[0080] Specifically, the first actuator includes: a rotating shaft 120 vertically arranged on the mounting side plate 110 and capable of rotating in a horizontal plane; a rotating seat 130 fixedly arranged on the rotating shaft 120; and a first actuator mechanism 140 for driving the rotating seat 130 to rotate and driving the rotating arm 500 to rotate;

[0081] wherein, the first connection end 510 of the rotating arm 500 is divided into a first connection point 511 and a second connection point 512, and the first connection point 511 is rotatably arranged on the rotating seat 130 along a vertical plane;

[0082] The first actuator further includes a first connecting rod 150 having a first end a151 and a second end a152, the first end a151 is rotatably connected to the second connection point 512 of the rotating arm 500, and the second end a152 is rotatably connected to the mounting side plate 110;

[0083] During the operation of the first actuator mechanism 140 to drive the first connection point 511 of the rotating base 130 and the rotating arm 500, the rotating arm 500 pivots around the second end a152 of the first link 150, performing a curvilinear motion to swing the vehicle door 2 upward or downward.

[0084] In this technical solution, aiming at the stress problem of the original hinge, the structure and installation of the rotating arm 500 are integrally optimized, which can greatly enhance the service life of the rotating arm 500.

[0085] Specifically, three connection points are provided on the rotating arm 500, namely the first connection points 511 on both sides, the second connection end 520, and the second connection point 512 in the middle position; the first connection point 511 is connected to the rotating base 130, the second connection end 520 is hinged to the vehicle door connecting arm 400, and the second connection point 512 serves as a pivot point. The first link 150 is provided at the second connection point 512. When the vehicle door 2 needs to be activated, that is, when opening or closing the vehicle door 2, by driving the rotation of the first connection point 511, the entire rotating arm 500 can rotate around the first link 150 as the axis of rotation. This design enables the rotating base 130 to only provide a guiding function for the rotating arm 500, without providing or providing only a small amount of the weight load of the rotating arm 500, thereby reducing the damage degree of the first connection point 511 and improving the service life of the entire first drive assembly 100.

[0086] In this embodiment, the first drive assembly 100 further includes:

[0087] A second link 160 having a first end b161 and a second end b162, the first end b161 being rotatably connected to the rotating base 130; a sector gear 170 provided at the first connection end 510 of the rotating arm 500; a bevel gear 180 meshing with the sector gear 170 and the bevel gear 180 being coaxial with the rotating shaft 120;

[0088] Wherein, the first actuator mechanism 140 is used to drive the rotation of the bevel gear 180 and the second end b162 of the second link 160 to perform an arc motion.

[0089] In this technical solution, the transmission method combining the sector gear 170 and the bevel gear 180 is adopted, so that when the first actuator mechanism 140 drives the bevel gear 180 to rotate, the first connection point 511 on the rotating arm 500 rotates in the vertical plane. During this process, the first actuator mechanism 140 also drives the second link 160 to rotate, causing the rotating base 130 to rotate in the horizontal plane. Finally, the rotating arm 500 pivots around the first link 150 to perform a curvilinear motion, causing the second connection point 512 of the rotating arm 500 to swing obliquely upward or obliquely downward.

[0090] In this embodiment, the first actuator mechanism 140 uses a power source and a differential to provide different rotation speeds for the second end b162 of the second connecting rod 160 and the bevel gear 180 in a differential manner. For the specific structure of the first actuator mechanism 140, the applicant has applied for similar technical patents, such as the patent with publication number CN115288553A. Since the present application does not further optimize the structure, the two structures are similar, so the first actuator mechanism 140 is not described in detail in this embodiment.

[0091] Embodiment 4:

[0092] This embodiment is a further improvement made on the basis of any of the above embodiments.

[0093] like Figure 2 , Figure 3 As shown, in this embodiment, specifically, a mounting plate 530 is provided on one side of the rotating arm 500 close to the second connecting end 520 thereof, and the second driving assembly 200 includes: a transmission arm 210; and a second actuator 220, which is used to drive the transmission arm 210 to extend or retract;

[0094] The end of the transmission arm 210 is disposed on the mounting plate 530 . When the switch lever 310 is in the first state, the second actuator 220 can drive the transmission arm 210 to extend and retract, thereby driving the door connecting arm 400 and the door 2 to rotate.

[0095] In this embodiment, the transmission arm 210 is driven to extend and retract by the second actuator 220, thereby realizing the horizontal opening and closing of the vehicle door 2. For the specific structure of the second actuator 220 mechanism, the applicant has applied for similar technical patents, such as the patent with publication number CN219492056U. Since the present application does not further optimize the structure, the two structures are similar. Therefore, the second actuator 220 mechanism is not described in detail in this embodiment.

[0096] The embodiments of the present disclosure have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments.
