[0004] However, the above-mentioned door body only relies on the rotation of the connecting rod to realize the opening or closing of the door body. The opening stroke of the door body is limited by the length of the connecting rod, and the movement stroke is limited. Summary of the invention

[0005] The purpose of the present application is to provide a door body connection mechanism, a door body mechanism and a vehicle, which are used to solve the problem that the existing vehicle door only relies on the rotation of a connecting rod to open the door body and has a limited opening stroke.

[0006] In order to achieve the above object, the technical solution adopted by the present invention is as follows:

[0007] On the one hand, an embodiment of the present application provides a door body connection mechanism for installation at the door structure of a vehicle frame. The door body connection mechanism includes a rotating mechanism, a mounting seat, and a slide rail. The rotating mechanism is used to be rotatably connected to the door structure of the vehicle frame. The mounting seat is connected to the rotating mechanism, and is used to move away from or close to the door structure of the vehicle frame under the drive of the rotating mechanism. The slide rail is arranged on the mounting seat, and includes a first slide rail and a second slide rail. The first slide rail is connected to the mounting seat, and the second slide rail is slidably connected to the first slide rail, and is used to connect to the door body to drive the door body to slide relative to the first slide rail.

[0008] According to the above-mentioned technical means, the door body connecting mechanism provided in the embodiment of the present application can rotate relative to the vehicle frame because the rotating mechanism is rotatably connected to the door structure of the vehicle frame. Since the mounting seat is connected to the rotating mechanism, the mounting seat can be driven to move when the rotating mechanism rotates, so that the mounting seat is away from or close to the door structure of the vehicle frame. At the same time, since the first slide rail is arranged on the mounting seat, the second slide rail is slidably connected to the first slide rail, and the second slide rail can slide relative to the first slide rail. In this way, the second slide rail can drive the door body connected to the second slide rail to slide, so as to realize the opening or closing of the door body. Therefore, the door body connecting mechanism provided in the embodiment of the present application can further increase the movement stroke of the door body by the relative movement of the first slide rail and the second slide rail while using the rotating mechanism to rotate the door body to open the door structure, thereby ensuring the movement stroke of the door body.

[0009] In a possible implementation, the door body connection mechanism further includes a first driving mechanism. The first driving mechanism is used to be installed at the door structure of the vehicle frame and is connected to the rotating mechanism. The first driving mechanism is used to drive the rotating mechanism to rotate.

[0010] According to the above technical means, the first driving mechanism can drive the rotating mechanism to rotate, so that the rotating mechanism drives the mounting seat to move, and finally realizes the movement of the door body relative to the vehicle frame. In this way, when the user needs to open the door body, he only needs to control the first driving mechanism to drive the rotating mechanism to move, and the door body can be opened without manual operation, which improves the user experience and the automatic operation of the vehicle.

[0011] In a possible embodiment, the rotating mechanism includes a rotating connecting rod. The rotating connecting rod includes a rotating shaft, a first connecting rod and a second connecting rod. The rotating shaft is used to be rotatably connected to the door structure of the vehicle frame. One end of the first connecting rod is connected to one end of the rotating shaft, and the other end is connected to the mounting seat. One end of the second connecting rod is connected to the other end of the rotating shaft, and the other end is connected to the mounting seat. The first driving mechanism includes a first driving motor. The first driving motor is used to be installed at the door structure of the vehicle frame. The first driving motor is connected to the rotating shaft and is used to drive the rotating shaft to rotate.

[0012] According to the above technical means, when the rotating shaft rotates, the other end of the first connecting rod and the other end of the second connecting rod rotate around the rotating shaft, thereby driving the mounting seat to move. The structure of the rotating connecting rod is simple and convenient for installation and fixing. At the same time, since the first connecting rod and the second connecting rod are respectively connected to the mounting seat, the mounting seat can move better and ensure the stability of the movement.

[0013] In a possible implementation, there are multiple rotating connecting rods. The other ends of the multiple first connecting rods and the other ends of the multiple second connecting rods are all rotatably connected to the mounting seat, and the rotation axis is parallel to the rotation axis of the rotating shaft.

[0014] According to the above technical means, through multiple rotating connecting rods, the pressure on each rotating connecting rod can be reduced, the service life of the rotating mechanism can be improved, and the use effect can be guaranteed. At the same time, because the other ends of the multiple first connecting rods and the other ends of the multiple second connecting rods are rotatably connected to the mounting seat, and the rotation axis is parallel to the rotation axis of the rotating shaft, the mounting seat can better move with the rotation of the rotating connecting rod.

[0015] In a possible implementation, a first thread is formed at the output end of the first driving motor, a second thread is formed on the peripheral wall of the rotating shaft, and the first thread meshes with the second thread.

[0016] According to the above technical means, the first drive motor can be used to drive the rotating shaft through the cooperation between the first thread and the second thread. In addition, by adopting the above method, the first drive motor can be arranged on the peripheral side of the rotating shaft, thereby facilitating the placement of the first drive motor.

[0017] In a possible implementation, the rotating connecting rod further includes a reinforcing rod, one end of which is connected between two ends of the first connecting rod, and the other end of which is connected between two ends of the second connecting rod.

[0018] According to the above technical means, the connection between the first connecting rod and the second connecting rod can be further strengthened by the reinforcing rod to ensure the stability of the connection between the first connecting rod and the second connecting rod.

[0019] In a possible implementation, the door body connection mechanism further includes a second driving mechanism. The second driving mechanism is disposed on the mounting seat and is used to connect with the door body to drive the door body to slide relative to the first slide rail.

[0020] According to the above technical means, the user can provide power to the door body by controlling the second driving mechanism, so that the door body can drive the second slide rail to move relative to the first slide rail, thereby enabling the door body to open or close the door structure of the vehicle frame.

[0021] In a possible implementation, the second slide rail includes an inner slide rail and an outer slide rail, wherein the inner slide rail is slidably connected to the first slide rail, and the outer slide rail is slidably connected to the inner slide rail.

[0022] According to the above technical means, since the second slide rail includes an inner slide rail and an outer slide rail that are slidably connected to each other, the inner slide rail and the outer slide rail are in a retracted state when the door is closed, the space occupied by the second slide rail can be reduced. At the same time, the design of the inner slide rail and the outer slide rail can ensure the movement range of the door body.

[0023] In a possible embodiment, the inner slide rail is formed with a first recessed portion. A portion of the first slide rail is located in the first recessed portion. The slide rail further includes a plurality of first balls. The plurality of first balls are disposed in the first recessed portion and abut against the first slide rail and the inner slide rail.

[0024] According to the above technical means, when the inner slide rail moves relative to the first slide rail, the first ball rolls to make the inner slide rail slide relative to the first slide rail. In this way, the friction between the inner slide rail and the first slide rail can be converted into rolling friction, which can reduce the friction force and make the movement of the inner slide rail smoother and easier.

[0025] In a possible embodiment, the outer slide rail is formed with a second recessed portion. A portion of the inner slide rail is located in the second recessed portion. The slide rail further includes a plurality of second balls. The plurality of second balls are disposed in the second recessed portion and abut against the inner slide rail and the outer slide rail.

[0026] According to the above technical means, when the outer slide rail moves relative to the inner slide rail, the second ball rolls to make the outer slide rail slide relative to the inner slide rail. In this way, the friction between the inner and outer slide rails can be converted into rolling friction, which can reduce the friction force and make the movement of the outer and inner slide rails smoother and easier.

[0027] On the other hand, an embodiment of the present application provides a door body mechanism, comprising a door body and any one of the above-mentioned door body connection mechanisms. The door body is connected to a second slide rail.

[0028] Since the door body mechanism provided in the embodiment of the present application includes any one of the above-mentioned door body connection mechanisms, it can solve the same technical problems as the above-mentioned door body connection mechanisms and achieve the same technical effects, which will not be repeated here.

[0029] In a possible implementation, the door body connection mechanism further includes a second drive mechanism. The second drive mechanism includes a second drive motor and a transmission gear. The second drive motor is disposed on a mounting seat, and the transmission gear is disposed at an output end of the second drive motor. The door body mechanism further includes a rack. The rack is disposed on the door body and meshes with the transmission gear.

[0030] According to the above technical means, since the rack is meshed with the transmission gear, when the second drive motor drives the transmission gear to rotate, the second slide rail connected to the door body can be driven by the rack to move relative to the first slide rail.

[0031] On the other hand, an embodiment of the present application provides a vehicle, including a vehicle frame and any one of the door mechanisms in the above aspect.

[0032] Since the vehicle provided in the embodiment of the present application includes the above-mentioned door body mechanism, it can solve the same technical problems as the above-mentioned door body mechanism and achieve the same technical effects, which will not be repeated here.

[0033] In a possible implementation manner, the door body connection mechanism is connected to a door sill of the vehicle frame.

[0034] According to the above technical means, when the door body connecting mechanism is arranged at the door sill of the vehicle frame, the space of the door sill can be utilized, and the door body connecting mechanism can be more conveniently designed and placed.

DETAILED DESCRIPTION

[0045] In order to enable ordinary persons in the art to better understand the technical solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0046] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims.

[0047] The embodiment of the present application provides a vehicle. The embodiment of the present application does not specifically limit the specific type of the vehicle. For example, the vehicle provided in the embodiment of the present application may be an electric vehicle, a hybrid vehicle, or a solar vehicle. At the same time, the vehicle provided in the embodiment of the present application may also be a vehicle of different forms. For example, the vehicle provided in the embodiment of the present application may be a sedan, a sport utility vehicle (SUV), or a multi-purpose vehicle (MPV).

[0048] like Figure 1 As shown, Figure 1 The schematic diagram of a part of the structure of a vehicle 100 provided in an embodiment of the present application, the vehicle 100 may include a vehicle frame 10. The vehicle frame 10 may form the overall shape of the exterior of the vehicle 100 and form a seating space for accommodating passengers. Figure 1As shown, the vehicle frame 10 is formed with a door structure (ie, an opening) through which a user can enter and exit.

[0049] At the same time, if Figure 1 As shown, the vehicle 100 provided in the embodiment of the present application further includes a door mechanism 20, which can be disposed at the door structure of the vehicle frame 10 and can be used to open or close the door structure of the vehicle frame 10. Figure 1 As shown, the door mechanism 20 may include a door body 30 and a door body connection mechanism 40. The door body connection mechanism 40 may be disposed on the vehicle frame 10 and connected to the vehicle frame 10. The door body 30 may be connected to the door body connection mechanism 40 and disposed on the vehicle frame 10 through the door body connection mechanism 40.

[0050] The door body 30 can cover or open the door structure of the vehicle frame 10. The door body connection mechanism 40 can enable the door body 30 to move relative to the vehicle frame 10, so that the door body 30 can open or close the door structure of the vehicle frame 10.

[0051] It is understandable that if Figure 1 As shown, the vehicle frame 10 may have multiple door structures. The door mechanism 20 may be disposed at the door structure at the rear of the vehicle frame 10. Figure 1 As shown, the vehicle 100 may further include a front door 50. The front door 50 may be disposed at a door structure at the front of the vehicle frame 10. Figure 2 As shown, Figure 2 for Figure 1 The schematic structural diagram of the vehicle 100 is shown when the front door 50 is in an open state. One side of the front door 50 can be rotatably connected to the vehicle frame 10 to open or close the door structure at the front of the vehicle frame 10.

[0052] It is understandable that in order to realize the basic functions of a car, the vehicle 100 may include components such as a chassis, a power system, and an electrical system.

[0053] The chassis may include components such as a transmission system and a drive system. The drive system can drive the wheels to rotate. Depending on the drive mode of the drive system, the drive system can be divided into front-wheel drive, rear-wheel drive, and four-wheel drive arrangements. The transmission system can transfer the power generated by the engine to the wheels.

[0054] The power system can provide power for the vehicle 100 so that the vehicle 100 can complete basic driving functions. The composition of the power system varies according to the type of the vehicle 100. For example, when the vehicle 100 is an electric vehicle, the power system may include an electric motor.

[0055] In order to power electrical components such as motors, the vehicle 100 provided in the embodiment of the present application also includes a battery system. The battery system may include a battery pack, which may be used to provide electrical energy. The battery pack may be electrically connected to the electrical components of the vehicle 100. In this way, the electrical energy of the battery pack may be transferred to the electrical components of the vehicle 100 for powering.

[0056] like Figure 3 As shown, Figure 3 for Figure 1 The vehicle 100 is shown in a structural schematic diagram at another angle. When the door body 30 of the vehicle 100 provided in the embodiment of the present application is in an open state, the door body 30 can be relatively staggered with the door structure of the vehicle frame 10 through the door body connecting mechanism 40, and there is a certain gap between the door body 30 and the vehicle frame 10.

[0057] To achieve Figure 3 The door connecting mechanism 40 provided in the embodiment of the present application is further described below. Figure 4 As shown, Figure 4 for Figure 1 As shown in the exploded view of the vehicle 100, the door body connection mechanism 40 includes a rotating mechanism 41, a mounting seat 42 and a slide rail 43. The rotating mechanism 41 can be rotatably connected to the door structure of the vehicle frame 10. Therefore, the rotating mechanism 41 can rotate relative to the vehicle frame 10.

[0058] Exemplarily, the rotation axis of the rotating mechanism 41 may be parallel to the height direction of the vehicle 100. Thus, when the rotating mechanism 41 rotates, the portion of the rotating mechanism 41 that is not connected to the vehicle frame 10 may move away from or close to the vehicle frame 10.

[0059] The mounting seat 42 is connected to the rotating mechanism 41, and is used to move under the drive of the rotating mechanism 41 to move away from or close to the door structure of the vehicle frame 10. Therefore, under the drive of the rotating mechanism 41, the mounting seat 42 can move away from or close to the door structure of the vehicle frame 10 as the rotating mechanism 41 rotates. At the same time, the mounting seat 42 can provide a mounting position for other components, facilitating the installation of other components.

[0060] The slide rail 43 is disposed on the mounting seat 42 and connected to the door body 30. The slide rail 43 can drive the door body 30 to slide relative to the mounting seat 42, so that the door body 30 can slide relative to the vehicle frame 10, so that the door body 30 can move to a position relatively staggered with the door structure, and open the door structure to facilitate the user to enter.

[0061] Among them, Figure 5 As shown, Figure 5This is one of the partial enlarged views of a vehicle 100 provided in an embodiment of the present application. The slide rail 43 may include a first slide rail 431 and a second slide rail 432. The first slide rail 431 is connected to the mounting seat 42, the second slide rail 432 is slidably connected to the first slide rail 431, and the second slide rail 432 can be connected to the door body 30 ( Figure 4 ) to drive the door body 30 to slide relative to the first slide rail 431.

[0062] Since the second slide rail 432 is connected to the door body 30, and the second slide rail 432 is slidably connected to the first slide rail 431, the door body 30 can move relative to the first slide rail 431 under the action of the second slide rail 432. Since the first slide rail 431 is connected to the mounting seat 42, the door body 30 can move relative to the mounting seat 42, and further the door body 30 can slide relative to the vehicle frame 10.

[0063] Therefore, the door body connection mechanism 40 provided in the embodiment of the present application, since the rotating mechanism 41 is rotatably connected to the door structure of the vehicle frame 10, the rotating mechanism 41 can rotate relative to the vehicle frame 10. Since the mounting seat 42 is connected to the rotating mechanism 41, the rotating mechanism 41 can drive the mounting seat 42 to move when rotating, so that the mounting seat 42 is away from or close to the door structure of the vehicle frame 10. At the same time, since the first slide rail 431 is arranged on the mounting seat 42, the second slide rail 432 is slidably connected to the first slide rail 431, and the second slide rail 432 can slide relative to the first slide rail 431. In this way, the second slide rail 432 can drive the door body 30 connected to the second slide rail 432 to slide, so as to open or close the door body 30. Therefore, the door body connection mechanism 40 provided in the embodiment of the present application, while using the rotating mechanism 41 to rotate the door body 30 to open the door structure, can also further increase the movement stroke of the door body 30 through the relative movement of the first slide rail 431 and the second slide rail 432, thereby ensuring the movement stroke of the door body 30.

[0064] Generally, in the related art, for a door body that can slide, the vehicle frame is generally provided with a slide rail to realize the sliding of the door, which makes the structural aesthetics of the vehicle frame poor. At the same time, the provision of a slide rail mechanism will also affect the strength of the vehicle frame, and the provision of the slide rail mechanism will also be limited by the structure of the vehicle frame. However, in the embodiment of the present application, in order to solve the above problems, a mounting seat 42 is provided on the vehicle frame 10, and a slide rail 43 is provided on the mounting seat 42, so that no other structure is required to be provided on the vehicle frame 10 to provide the slide rail 43, reducing the structural restrictions on the vehicle frame 10, so that the shape of the vehicle frame 10 can be more diversified to meet the different needs of users. At the same time, since the slide rail 43 is provided on the mounting seat 42, it will not be limited by the structure of the vehicle frame 10, and the design is more flexible and convenient.

[0065] In some embodiments, Figure 6As shown, Figure 6 The second partial enlarged view of a vehicle 100 provided in an embodiment of the present application, the door connecting mechanism 40 is connected to the door sill 101 of the vehicle frame 10. When the door connecting mechanism 40 is arranged at the door sill 101 of the vehicle frame 10, the space of the door sill 101 can be utilized, and the door connecting mechanism 40 can be more conveniently designed and placed. Figure 4 and Figure 6 As shown, the door connecting mechanism 40 can be arranged at the door sill 101 below the C-pillar of the vehicle frame 10, making use of the space at the position of the door sill 101 below the C-pillar, which is more convenient to arrange.

[0066] Of course, in other embodiments, the door body connection mechanism 40 may also be disposed at other positions. For example, the door body 30 connection structure may also be disposed above the C-pillar, close to the inner side of the door body 30 .

[0067] In some embodiments, Figure 7 As shown, Figure 7 FIG. 4 is a schematic diagram of a door connecting mechanism 40 provided in an embodiment of the present application. The door connecting mechanism 40 further includes a first driving mechanism 44. The first driving mechanism 44 is used to be installed on the vehicle frame 10 ( Figure 6 ) at the door structure and connected to the rotating mechanism 41. The first driving mechanism 44 is used to drive the rotating mechanism 41 to rotate.

[0068] Thus, the first driving mechanism 44 can drive the rotating mechanism 41 to rotate, so that the rotating mechanism 41 drives the mounting seat 42 to move, and finally the door body 30 is relative to the vehicle frame 10 ( Figure 4 In this way, when the user needs to open the door body 30, the user only needs to control the first driving mechanism 44 to drive the rotating mechanism 41 to move to open the door body 30, without manual operation, thereby improving the user experience and the automatic operation of the vehicle 100.

[0069] Of course, in other embodiments, the door body connection mechanism 40 may not include the first drive mechanism 44. In this case, when the user needs to open or close the door body 30, the door body 30 can be directly pulled so that the door body 30 drives the rotating mechanism 41 to rotate, thereby realizing the opening or closing of the door body 30. In this case, the structure of the vehicle 100 is relatively simple and the manufacturing cost is lower. It is understandable that the vehicle 100 provided in the embodiment of the present application can be set according to actual selection whether to set the first drive mechanism 44.

[0070] Continue to refer to Figure 7In order to enable the rotating mechanism 41 to rotate, in some embodiments, the rotating mechanism 41 includes a rotating link 415. The rotating link 415 includes a rotating shaft 411, a first link 412, and a second link 413. The rotating shaft 411 can be rotatably connected to the door structure of the vehicle frame 10. In this way, the rotating shaft 411 can rotate relative to the vehicle frame 10.

[0071] The first driving mechanism 44 may include a first driving motor 441, and the first driving motor 441 may be installed at the door structure of the vehicle frame 10. The first driving motor 441 may be connected to the rotating shaft 411. In this way, the rotating shaft 411 may rotate under the drive of the first driving motor 441.

[0072] Among them, one end of the first connecting rod 412 is connected to one end of the rotating shaft 411, and the other end is connected to the mounting seat 42. One end of the second connecting rod 413 is connected to the other end of the rotating shaft 411, and the other end is connected to the mounting seat 42. Therefore, when the rotating shaft 411 rotates, the other end of the first connecting rod 412 and the other end of the second connecting rod 413 rotate around the rotating shaft 411, thereby driving the mounting seat 42 to move. The structure of the rotating connecting rod 415 is simple and convenient for installation and fixing. At the same time, since the first connecting rod 412 and the second connecting rod 413 are respectively connected to the mounting seat 42, the mounting seat 42 can be better moved to ensure the stability of the movement.

[0073] In addition, since the door body connection mechanism 40 provided in the embodiment of the present application can increase the movement stroke of the door body 30 through the relative movement of the first slide rail 431 and the second slide rail 432, the first connecting rod 412 and the second connecting rod 413 only need to be able to unfold the door body 30 and have a certain distance from the vehicle frame 10, and there is no need to set a longer length. In this way, the first connecting rod 412 and the second connecting rod 413 can withstand greater force due to their shorter length, thereby ensuring the firmness of the connection, and only the first connecting rod 412 and the second connecting rod 413 of the chair back can achieve a good support effect.

[0074] Of course, in other embodiments, the rotating mechanism 41 may also have other components, which can be selected according to actual conditions, and are described here only as examples. For example, in some embodiments, the rotating mechanism 41 may also include a rotating shaft 411 and a single connecting rod. One end of the single connecting rod is connected to the rotating shaft 411, and the other end is connected to the mounting seat 42. In this way, the rotating mechanism 41 can also drive the mounting seat 42 to rotate.

[0075] In some embodiments, there are multiple rotating links 415. The other ends of the multiple first links 412 and the other ends of the multiple second links 413 are all rotatably connected to the mounting seat 42, and the rotation axis 411 line is parallel to the rotation axis 411 line of the rotation axis 411. In this way, through the multiple rotating links 415, the pressure on each rotating link 415 can be reduced, the service life of the rotating mechanism 41 is improved, and the use effect is guaranteed.

[0076] At the same time, since the other ends of the multiple first connecting rods 412 and the other ends of the multiple second connecting rods 413 are rotatably connected to the mounting seat 42, and the rotating axis 411 line is parallel to the rotating axis 411 line of the rotating axis 411, the mounting seat 42 can better move with the rotation of the rotating link 415.

[0077] It is understandable that the specific structure of the mounting base 42 can be designed according to actual conditions. Figure 7 As shown, the mounting seat 42 may include a mounting plate 421 and a mounting portion 422. The mounting portion 422 is disposed on one side of the mounting plate 421 and is connected to the mounting plate 421. In order to achieve the rotational connection between the first connecting rod 412 and the second connecting rod 413 and the mounting seat 42. The mounting seat 42 may also include a connecting shaft 423. The connecting shaft 423 may be inserted into the mounting portion 422 and rotationally connected to the mounting plate 421. At the same time, the other end of the first connecting rod 412 and the other end of the second connecting rod 413 may be rotationally connected to both ends of the connecting shaft 423. In this way, the first connecting rod 412 and the second connecting rod 413 may be rotationally connected to the mounting seat 42 through the connecting shaft 423.

[0078] In addition, it is understood that the number of the rotating connecting rods 415 can be set according to actual conditions. Figure 7 As shown, the number of the rotating connecting rods 415 can be two. In this case, the two first connecting rods 412 and the two second connecting rods 413 can roughly form a parallelogram structure. Figure 7 As shown, the specific shapes of the first connecting rod 412 and the second connecting rod 413 can be designed according to actual conditions. For example, the first connecting rod 412 and the second connecting rod 413 can be in a curved structure. At this time, the curved structure of the first connecting rod 412 and the second connecting rod 413 can avoid other structures, facilitating the movement of the first connecting rod 412 and the second connecting rod 413.

[0079] In order to enable the first driving mechanism 44 to drive the rotating shaft 411 to rotate, in some embodiments, a first thread (not shown) is formed at the output end of the first driving motor 441. A second thread (not shown) is formed on the peripheral wall of the rotating shaft 411. The first thread is meshed with the second thread. In this way, through the mutual cooperation of the first thread and the second thread, the first driving motor 441 can be used to drive the rotating shaft 411. In addition, by adopting the above method, the first driving motor 441 can be arranged on the peripheral side of the rotating shaft 411, thereby facilitating the placement of the first driving motor 441.

[0080] Of course, the first drive motor 441 can also drive the rotating shaft 411 in other ways. For example, in other implementations, the output end of the first drive motor 441 can be directly connected to the end of the rotating shaft 411. In this way, the first drive motor 441 can directly drive the rotating shaft 411 to rotate.

[0081] In some embodiments, Figure 7 As shown, the rotating connecting rod 415 further includes a reinforcing rod 414. One end of the reinforcing rod 414 is connected between the two ends of the first connecting rod 412, and the other end is connected between the two ends of the second connecting rod 413. In this way, the connection between the first connecting rod 412 and the second connecting rod 413 can be further strengthened by the reinforcing rod 414, thereby ensuring the stability of the connection between the first connecting rod and the second connecting rod 413.

[0082] It is understandable that the number of reinforcing rods 414 can be set according to actual conditions. Figure 1 As shown, the number of the reinforcing rod 414 can be one. Of course, the number of the reinforcing rod 414 can also be multiple. The multiple reinforcing rods 414 are arranged at intervals along the extension direction of the first connecting rod 412. The specific number can be set according to actual conditions, and is only described here as an example.

[0083] In some embodiments, Figure 7 As shown, the door body connection mechanism 40 may further include a second drive mechanism 45. The second drive mechanism 45 is disposed on the mounting seat 42, and the second drive mechanism 45 may be connected to the door body 30 ( Figure 4 ) is connected to drive the door body 30 to slide relative to the first slide rail 431. Therefore, the user can control the second driving mechanism 45 to provide power to the door body 30, so that the door body 30 can drive the second slide rail 432 to move relative to the first slide rail 431, so that the door body 30 can open or close the door structure of the vehicle frame 10.

[0084] Of course, in other embodiments, the door body connection mechanism 40 may not include the second drive mechanism 45. In this case, the user can directly pull the door body 30 to provide power for the door body 30, so that the door body 30 can drive the second slide rail 432 to slide relative to the first slide rail 431, and the door structure of the vehicle frame 10 can also be opened and closed. It can be understood that the vehicle 100 provided in the embodiment of the present application can be set according to actual needs.

[0085] It is understandable that the specific composition and driving mode of the second driving mechanism 45 can be designed according to actual conditions. Figure 7 As shown, the second driving mechanism 45 may include a second driving motor 451 and a transmission gear 452. The second driving motor 451 is disposed on the mounting seat 42, and the transmission gear 452 is disposed at the output end of the second driving motor 451.

[0086] At the same time, the door body mechanism 20 also includes a rack (not shown in the figure). The rack is arranged on the door body 30 and meshes with the transmission gear 452. Specifically, the rack can be arranged on the side of the door body 30 close to the door frame. In this way, the rack can be hidden by the door body 30 and will not affect the overall appearance of the vehicle 100. Since the rack is meshed with the transmission gear 452, when the second drive motor 451 drives the transmission gear 452 to rotate, the second slide rail 432 connected to the door body 30 can be driven by the rack to move relative to the first slide rail 431.

[0087] Of course, in other embodiments, the second drive mechanism 45 may also have other components and structures, and drive the door body 30 to move through other driving methods. The specific design can be based on actual conditions, as long as the effect of driving the door body 30 to move can be achieved. It is only described here as an example without further limitation.

[0088] In some embodiments, Figure 5 As shown, the second slide rail 432 includes an inner slide rail 433 and an outer slide rail 434. The inner slide rail 433 is slidably connected to the first slide rail 431. The outer slide rail 434 is slidably connected to the inner slide rail 433. In this way, since the second slide rail 432 includes the inner slide rail 433 and the outer slide rail 434 slidably connected to each other, the inner slide rail 433 and the outer slide rail 434 are in a retracted state when the door is closed, so as to reduce the space occupied by the second slide rail 432. At the same time, the design of the inner slide rail 433 and the outer slide rail 434 can ensure that the door body 30 ( Figure 4 )'s movement itinerary.

[0089] Of course, in other embodiments, the second slide rail 432 may also include only the inner slide rail 433. At this time, in order to make the stroke of the inner slide rail 433 longer, the length of the first slide rail 431 may be increased so that the inner slide rail 433 can slide a longer distance relative to the first slide rail 431.

[0090] In some embodiments, Figure 8 As shown, Figure 8 A cross-sectional view of a slide rail 43 provided in an embodiment of the present application, wherein the inner slide rail 433 is formed with a first recessed portion 4331. A portion of the first slide rail 431 is located in the first recessed portion 4331. The slide rail 43 further includes a plurality of first balls 435. The plurality of first balls 435 are disposed in the first recessed portion 4331 and abut against the first slide rail 431 and the inner slide rail 433.

[0091] Therefore, if Figure 8 As shown, when the inner slide rail 433 moves relative to the first slide rail 431, the first ball 435 rolls to make the inner slide rail 433 slide relative to the first slide rail 431. In this way, the friction between the inner slide rail 433 and the first slide rail 431 can be converted into rolling friction, which can reduce the friction force and make the movement of the inner slide rail 433 smoother and easier.

[0092] For example, Figure 8 As shown, two first recessed portions 4331 may be formed on the upper and lower sides of the inner slide rail 433. Accordingly, a portion of the first slide rail 431 is located in the two first recessed portions 4331. It is understood that the shape of the first recessed portions 4331 may be designed according to actual conditions so that the first ball 435 can be better engaged in the first recessed portions 4331 and is not easy to fall off from the first recessed portions 4331.

[0093] Of course, the first slide rail 431 may also be directly slidably connected to the inner slide rail 433 without providing the first ball bearing 435. In this case, the overall composition of the slide rail 43 is relatively simple.

[0094] Similarly, continue to refer to Figure 8 In some embodiments, the outer rail 434 is formed with a second recessed portion 4341. A portion of the inner rail 433 is located in the second recessed portion 4341. The rail 43 further includes a plurality of second balls 436. The plurality of second balls 436 are disposed in the second recessed portion 4341 and abut against the inner rail 433 and the outer rail 434.

[0095] When the outer slide rail 434 moves relative to the inner slide rail 433, the second ball bearing 436 rolls to make the outer slide rail 434 slide relative to the inner slide rail 433. In this way, the friction between the inner slide rail 433 and the outer slide rail 434 can be converted into rolling friction, which can reduce the friction force, making the movement of the outer slide rail 434 and the inner slide rail 433 smoother and easier. Similarly, in other embodiments, the outer slide rail 434 can also be directly slidably connected to the inner slide rail 433 without the second ball bearing 436. In this case, the overall composition of the slide rail 43 is relatively simple.

[0096] In addition, in order to ensure that the door body 30 can be locked well, Figure 4 As shown, the vehicle 100 provided in the embodiment of the present application may further include a sky lock 60, a ground lock 70 and a rear door lock 80. For example, the sky lock 60 may be arranged above the door structure of the vehicle frame 10. The ground lock 70 may be arranged below the door structure of the vehicle frame 10, and the rear door lock 80 may be arranged behind the door structure of the vehicle frame 10. Through the sky lock 60, the ground lock 70 and the rear door lock 80, when the door body 30 is in a closed state, the sky lock 60, the ground lock 70 and the rear door lock 80 may be connected to the door body 30 to restrict the movement of the door body 30.

[0097] The above are only specific implementations of the present application, but the protection scope of the present application is not limited thereto, and any changes or substitutions within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
