[0054] As described in the background art, at the present stage, the traditional rear door usually opens integrally upward around a single axis. There are also similar side - opening rear doors for off - road vehicles. Each time people take or place items, they need to open the rear door integrally, which is not flexible enough. And when the vehicle is parked, enough clearance needs to be reserved from the wall, otherwise the rear door cannot be opened. In addition, the rear door that opens integrally upward around a single axis has no functional extensibility and is relatively single - function.

[0055] To solve the above technical problems, the embodiments of the present application provide a ground door device and a vehicle. The ground door device includes a ground door, a rotating shaft mechanism, and a driving assembly.

The driving assembly is located on one side of the ground door and is connected to the ground door. The driving assembly is used to drive the ground door to rotate. The driving assembly includes a first connecting rod and a second connecting rod. One end of the second connecting rod is connected to the first connecting rod, and the other end of the second connecting rod is connected to the ground door. When the ground door is in the open state, the end of the second connecting rod connected to the ground door is far from the first connecting rod, so that the first connecting rod and the second connecting rod tend to be in a straight line. When the ground door is in the closed state, the end of the second connecting rod connected to the ground door is close to the first connecting rod, so that the first connecting rod and the second connecting rod are in a folded state. The vehicle includes a vehicle body and the above - mentioned ground door device. Among them, the ground door device is located at one end of the vehicle body and is connected to the vehicle body. In this way, the present application can set the ground door device to achieve segmented opening of the sky - ground door, meeting the requirement that only one sky door or one ground door needs to be opened when taking small items, and the method is more flexible. It also reduces the opening length of the rear door in the horizontal direction, making it easier to open the rear door without worrying about scratching the rear door and the wall when opening. In addition, the ground door device can be used as a platform for picnics, selling small commodities, and fishing, increasing the functional extensibility and improving the overall performance of the vehicle.

[0056] In order to make the above-mentioned objects, features, and advantages of the embodiments of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0057] The embodiments of the present application provide a ground door device and a vehicle. The ground door device is provided to realize the segmented opening of the sky and ground doors, so that when taking small items, only one sky door or ground door needs to be opened, and the method is more flexible. It also reduces the opening length of the rear door in the horizontal direction, making it easier to open the rear door without worrying about scratching the rear door and the wall when opening. In addition, the ground door device can be used as a platform for picnics, small commodity sales, and fishing, increasing the functional extensibility and improving the overall performance of the vehicle. The following will introduce the specific structures of the ground door device and the vehicle provided by the embodiments of the present application with reference to the accompanying drawings.

[0058] Refer to Figure 1 In the first aspect of the embodiments of the present application, a ground door device 100 is provided. The ground door device 100 may include a ground door 200, a rotating shaft mechanism 300, and a driving component 400. Among them, in a possible implementation manner, the shape of the ground door 200 may be a rectangular structure. The embodiments of the present application do not limit the shape of the ground door 200 here, as long as the ground door 200 is adapted to the vehicle trunk. In the embodiments of the present application, one end of the rotating shaft mechanism 300 may be connected to the ground door 200, so that the ground door 200 can rotate around the rotating shaft mechanism 300, thereby realizing the opening or closing of the ground door 200. In a possible implementation manner, the rotating shaft mechanism 300 may be located at one end in the width direction of the ground door 200, and the rotating shaft mechanism 300 may be located on one of the inner side walls of the vehicle body 500. The driving component 400 may be located at one end in the length direction of the ground door 200, and the driving component 400 may also be located on the vehicle body 500. One end of the driving component 400 may also be connected to the ground door 200, so that the driving component 400 can be used to drive the ground door 200 to rotate.

[0059] Refer to Figure 1 、 Figure 3 and Figure 4, on the basis of the above embodiments, the driving assembly 400 may include a first connecting rod 423 and a second connecting rod 425. Among them, in a possible implementation manner, one end of the second connecting rod 425 may be connected to the first connecting rod 423, and the other end of the second connecting rod 425 may be connected to the ground door 200. Driving the first connecting rod 423 can drive the second connecting rod 425 and then drive the ground door 200 to rotate around the rotating shaft mechanism 300, so as to realize the opening and closing of the ground door 200. In the embodiments of the present application, when the ground door 200 is in the open state, the end of the second connecting rod 425 connected to the ground door 200 is far from the first connecting rod 423, so that the first connecting rod 423 and the second connecting rod 425 tend to be in a straight line, and then the second connecting rod 425 pushes the ground door 200 to rotate towards the outside of the vehicle body 500 to realize the opening of the ground door 200. When the ground door 200 is in the closed state, the end of the second connecting rod 425 connected to the ground door 200 is close to the first connecting rod 423, so that the first connecting rod 423 and the second connecting rod 425 are in a folded state, and then the second connecting rod 425 drives the ground door 200 to rotate towards the inside of the vehicle body 500 to realize the closing of the ground door 200.

[0060] On the basis of the above embodiments, when the ground door 200 is in the closed state, the folding angle between the first connecting rod 423 and the second connecting rod 425 may be less than or equal to 90°, that is, the folding angle between the first connecting rod 423 and the second connecting rod 425 is an acute angle. Thus, the first connecting rod 423 and the second connecting rod 425 occupy less space, and further save the internal space of the vehicle body 500. In a possible implementation manner, the end of the second connecting rod 425 connected to the ground door 200 may be in contact with the first connecting rod 423, so that the first connecting rod 423 and the second connecting rod 425 are further folded.

[0061] Continue to refer to Figure 1 , on the basis of the above embodiments, among them, in a possible implementation manner, the number of the rotating shaft mechanisms 300 may be at least two, and the embodiments of the present application do not limit this here. In the embodiments of the present application, an example is given with the number of the rotating shaft mechanisms 300 being two. The two rotating shaft mechanisms 300 may be respectively located at both ends of the inner side wall of the vehicle body 500 in the width direction, which can drive the ground door 200 to rotate more stably and facilitate the opening or closing of the ground door 200.

[0062] Refer to Figure 2, when specifically embodied in the embodiments of the present application, further, each rotating shaft mechanism 300 may include: a fixing member 310, a first connecting member 320, and a rotating shaft 330. Among them, in a possible implementation manner, a first through hole 321 may be formed at one end of the first connecting member 320. It can be understood that the diameter dimension of the first through hole 321 may be greater than or equal to the diameter dimension of the rotating shaft 330, so that the first through hole 321 can be penetrated by the rotating shaft 330, and further the rotating shaft 330 can be located on the first connecting member 320 through the first through hole 321. In this way, the rotating shaft 330 can be located at one end of the first connecting member 320, and the other end of the first connecting member 320 can be connected to the fixing member 310. In a possible implementation manner, the fixing member 310 may be a hinge structure, and the embodiments of the present application do not limit the form of the fixing member 310 here. In the embodiments of the present application, one end of the fixing member 310 is connected to the first connecting member 320, and the other end of the fixing member 310 can be used to connect to the vehicle body 500, so that the entire rotating shaft mechanism 300 is located inside the vehicle body 500.

[0063] Continue to refer to Figure 2 , on the basis of the above embodiments, further, each rotating shaft mechanism 300 may further include: an extension arm 340. Among them, the extension arm 340 may be located on the first connecting member 320. In a possible implementation manner, the extension arm 340 may be located at the end of the first connecting member 320 where the rotating shaft 330 is provided, so that the extension arm 340 can extend along one end of the rotating shaft 330 toward the landing door 200. It can be understood that one end of the extension arm 340 can be connected to the rotating shaft 330, and the other end of the extension arm 340 can be fixed to the landing door 200. In this way, the rotating shaft 330 can drive the extension arm 340 to rotate, so that the extension arm 340 can rotate around the rotating shaft 330, and further drive the landing door 200 to rotate to realize the opening or closing of the landing door 200. In a possible implementation manner, a through hole may also be formed at the end of the extension arm 340 facing the rotating shaft 330, and the rotating shaft 330 can also pass through the through hole and be located on the extension arm 340. Among them, the through hole may coincide with the first through hole 321 on the first connecting member 320, so that the rotating shaft 330 can be located at one end of the first connecting member 320 and also at one end of the extension arm 340.

[0064] Figure 3 Schematic structural diagram of the drive assembly 400 when the landing door 200 is open, Figure 4 Schematic structural diagram of the drive assembly 400 when the landing door 200 is closed. Refer to Figure 3, on the basis of the above embodiments, further, the driving assembly 400 may include: a driving member 410 and a transmission mechanism 420. In a possible implementation, the driving member 410 may be a rotary motor, and the rotary motor may provide driving force for the transmission mechanism 420. Among them, one end of the transmission mechanism 420 may be connected to the driving member 410, and the other end of the transmission mechanism 420 may be connected to the ground door 200. It can be understood that the driving member 410 can be used to drive the transmission mechanism 420, so that the transmission mechanism 420 can stretch or contract, and then drive the ground door 200 to open or close. In a possible implementation, when the driving member 410 drives the transmission mechanism 420 to stretch, the transmission mechanism 420 at this time can push the ground door 200 to rotate towards the outside of the vehicle body 500, so as to realize the open state of the ground door 200. Correspondingly, when the driving member 410 drives the transmission mechanism 420 to contract, the transmission mechanism 420 at this time can drive the ground door 200 to rotate towards the inside of the vehicle body 500, so as to realize the closed state of the ground door 200.

[0065] Reference Figure 3 And Figure 4 , on the basis of the above embodiments, the transmission mechanism 420 may further include: a first rotating shaft 421 and a second connecting member 422. Among them, the second connecting member 422 may be fixedly connected to the driving member 410, and the second connecting member 422 may be provided with a second through hole 4221. In a possible implementation, the second through hole 4221 may be provided at one end of the second connecting member 422 facing away from the driving member 410. It can be understood that the diameter dimension of the second through hole 4221 may be greater than or equal to the diameter dimension of the first rotating shaft 421, so that the second through hole 4221 can be penetrated by the first rotating shaft 421, and then the first rotating shaft 421 can be located on the second connecting member 422 through the second through hole 4221. In this way, the first rotating shaft 421 may be located at one end of the second connecting member 422, and the other end of the second connecting member 422 may be connected to the driving member 410.

[0066] Continue to refer to Figure 3 And Figure 4, on the basis of the above embodiments, the first connecting rod 423 may be located at the other end of the first rotating shaft 421. In this way, one end of the first rotating shaft 421 is inserted into the second through hole 4221 of the second connecting member 422, the other end of the first rotating shaft 421 is connected to one end of the first connecting rod 423, and the first connecting rod 423 is provided with a third through hole 4231. In a possible implementation manner, the end of the first connecting rod 423 connected to the first rotating shaft 421 may be provided with the third through hole 4231. It can be understood that the diameter dimension of the third through hole 4231 may be greater than or equal to the diameter dimension of the first rotating shaft 421, so that the third through hole 4231 can be penetrated by the first rotating shaft 421, and further the other end of the first rotating shaft 421 can penetrate through the third through hole 4231 and be connected to the first connecting rod 423. In this way, when the driving member 410 drives the first rotating shaft 421 to rotate, the first rotating shaft 421 can drive the first connecting rod 423 to rotate during the rotation process. In a possible implementation manner, when the first rotating shaft 421 is driven to rotate, the first connecting rod 423 may rotate towards the outside of the vehicle body 500, so as to push the ground door 200 to open outwards. Correspondingly, the first connecting rod 423 may also rotate towards the inside of the vehicle body 500, so as to drive the ground door 200 to close inwards.

[0067] Continue to refer to Figure 3 and Figure 4 , on the basis of the above embodiments, the transmission mechanism 420 may further include: a second rotating shaft 424. The second rotating shaft 424 may be connected to the first connecting rod 423, and the first connecting rod 423 is further provided with a fourth through hole 4232. In a possible implementation manner, the end of the first connecting rod 423 connected to the second rotating shaft 424 may be provided with the fourth through hole 4232. It can be understood that the diameter dimension of the fourth through hole 4232 may be greater than or equal to the diameter dimension of the second rotating shaft 424, so that the fourth through hole 4232 can be penetrated by the second rotating shaft 424, and further the second rotating shaft 424 can penetrate through the fourth through hole 4232 and be connected to the first connecting rod 423. In this way, when the driving member 410 drives the first rotating shaft 421 to rotate, the first rotating shaft 421 can drive the first connecting rod 423 to rotate during the rotation process, so as to drive the second rotating shaft 424 to rotate. In a possible implementation manner, the third through hole 4231 and the fourth through hole 4232 may be respectively opened at both ends of the first connecting rod 423 in the length direction, so that the first rotating shaft 421 and the second rotating shaft 424 respectively penetrate through both ends of the first connecting rod 423 in the length direction.

[0068] Continue to refer to Figure 3 and Figure 4, based on the above embodiments, wherein the second link 425 may be located at one end of the first link 423. It can be understood that the second link 425 and the first link 423 may be connected by a second rotating shaft 424, and the second link 425 and the first link 423 may rotate relative to each other through the second rotating shaft 424. In a possible implementation, a fifth through hole 4251 may be formed at one end of the second link 425 connected to the second rotating shaft 424, and the fifth through hole 4251 may coincide with the fourth through hole 4232. It can be understood that the diameter dimension of the fifth through hole 4251 may be greater than or equal to the diameter dimension of the second rotating shaft 424, so that the fifth through hole 4251 can be penetrated by the second rotating shaft 424, and further the second rotating shaft 424 can also be penetrated through the fifth through hole 4251 and connected to the second link 425. In this way, the second rotating shaft 424 can be respectively penetrated through the fourth through hole 4232 and the fifth through hole 4251, so that the second link 425 and the first link 423 can be connected by the second rotating shaft 424. In a possible implementation, when the second rotating shaft 424 is driven to rotate, the second link 425 may rotate toward the outside of the vehicle body 500, thereby pushing the ground door 200 to open outward. At this time, the first link 423 and the second link 425 may tend to be in a straight line. Correspondingly, the second link 425 may also rotate toward the inside of the vehicle body 500, thereby driving the ground door 200 to close inward. At this time, the first link 423 and the second link 425 are arranged in a folded state to occupy a smaller space inside the vehicle body 500.

[0069] Continue to refer to Figure 3 and Figure 4, on the basis of the above embodiments, the transmission mechanism 420 may further include: a third rotating shaft 426. The third rotating shaft 426 may be connected to the second connecting rod 425, and a sixth through hole 4252 may be formed in the second connecting rod 425. In a possible implementation manner, the sixth through hole 4252 may be formed at one end of the second connecting rod 425 connected to the third rotating shaft 426. It can be understood that the diameter dimension of the sixth through hole 4252 may be greater than or equal to the diameter dimension of the third rotating shaft 426, so that the sixth through hole 4252 can be penetrated by the third rotating shaft 426, and then the third rotating shaft 426 can penetrate through the sixth through hole 4252 and be connected to the second connecting rod 425. In this way, when the driving member 410 drives the second rotating shaft 424 to rotate, the second rotating shaft 424 can drive the second connecting rod 425 to rotate during the rotation process, thereby driving the third rotating shaft 426 to rotate. In a possible implementation manner, the fifth through hole 4251 and the sixth through hole 4252 may be respectively formed at both ends of the second connecting rod 425 in the length direction, so that the second rotating shaft 424 and the third rotating shaft 426 respectively penetrate through both ends of the second connecting rod 425 in the length direction. It can be understood that the other end of the third rotating shaft 426 may be connected to the ground door 200, so that the third rotating shaft 426 can drive the ground door 200 to rotate. In this way, when the second connecting rod 425 rotates toward the outside of the vehicle body 500, the third rotating shaft 426 can also rotate, thereby pushing the ground door 200 to open outward. At this time, the first connecting rod 423 and the second connecting rod 425 may tend to be in a straight line. Correspondingly, the second connecting rod 425 can also rotate toward the inside of the vehicle body 500, thereby driving the ground door 200 to close inward. At this time, the third rotating shaft 426 can be almost attached to the first connecting rod 423, so that the first connecting rod 423 and the second connecting rod 425 are arranged in a folded state.

[0070] The second aspect of the present application provides a vehicle (not shown in the figure), including a vehicle body 500 and the above-mentioned ground door device 100. The ground door device 100 may be located at one end of the vehicle body 500, and the ground door device 100 may be connected to the vehicle body 500. In a possible implementation manner, the ground door device 100 may be located at the tail of the vehicle body 500, so that the ground door device 100 and the vehicle body 500 together form a complete vehicle.

[0071] In the embodiments of the present application, in combination with the vehicle styling requirements and functional requirements, the transmission mechanism 420 is set to meet the force arm stroke, the casting process is adopted to ensure the overall strength of the transmission mechanism 420, and it is cooperated with the driving member 410 to ensure that the ground door 200 realizes the electric opening or closing state, meets the segmented opening of the sky-earth door 200 of the vehicle rear door, increases user convenience, and diversifies the opening methods.

[0072] In the embodiments of the present application, the ground door device 100 is provided to achieve segmented opening of the sky and ground doors, so that when taking small items, only one sky door or the ground door 200 needs to be opened, and the method is more flexible. Compared with the rear door that is integrally opened upward by a single shaft in the related art, the ground door device 100 provided in the present application also reduces the opening length of the rear door in the horizontal direction, making it easier to open the rear door without worrying about scratching the rear door and the wall when opening. In addition, when the ground door device 100 is opened, the ground door 200 can be opened to an angle parallel to the horizontal plane, so that the ground door device 100 can be used as a platform for picnics, selling small commodities, and fishing, increasing the functional extensibility and improving the overall performance of the vehicle.
