Description

Technical Field

[0001] This application relates to the technical field of vehicles, and particularly to a door assembly and a vehicle. Background Art

[0002] With the continuous development of the automotive industry, people's usage scenarios for vehicles are becoming increasingly diverse, such as outdoor camping, door poker and other entertainment items. At the same time, there is also an increasing pursuit of a good user experience, such as the upper and lower spaces of the vehicle, the rotational use of seats, etc. Currently, mainstream models on the market all have a B-pillar on the side panel. To a certain extent, the existence of the B-pillar restricts the user scenarios of the vehicle and also causes certain limitations in the interior space of the vehicle, making it impossible to maximize the use scenarios of the seats.

[0003] Therefore, it is necessary to develop a door assembly to meet people's needs. Summary of the Invention

[0004] The purpose of this application is to disclose a door assembly and a vehicle.

[0005] In a first aspect, this application discloses a door assembly. The door assembly is applied to a vehicle without a B-pillar and includes a first door, a second door, a first driving mechanism, a second driving mechanism, and a third driving mechanism. The first driving mechanism, the second driving mechanism, and the third driving mechanism cooperate to drive the first door to achieve three-dimensional motion and to fully close or fully open the first door. When the first door and the second door are in a fully closed state, they close the same entrance and exit of the vehicle in the front-rear direction of the vehicle, and the front end of the first door is located inside the rear end of the second door. The first driving mechanism, the second driving mechanism, and the third driving mechanism also cooperate with each other to drive the first door to rotate in the horizontal direction so that the first door is in a non-fully open state. In the non-fully open state, the front end of the first door is pressed by the rear end of the second door, and a first angle is formed between the first door and the vehicle body.

[0006] In some embodiments, the first angle is A, and the driving mechanism also drives the first door to form a second angle B with the vehicle body, where C ≤ B < A, and the angle C is the lower limit angle when the second door presses the first door when the first door is not fully open.

[0007] In some embodiments, the preset value is a, where 0 cm ≤ a ≤ 1 cm.

[0008] In some embodiments, the door assembly includes a controller, which is connected to the first driving mechanism, the second driving mechanism, and the third driving mechanism, and drives the first door to switch between the first angle A, the second angle B, and the angle C.

[0009] In some embodiments, the door assembly includes a controller. The first driving mechanism includes a first motor and a first position sensor, and the second driving mechanism includes a second motor and a second position sensor. The controller controls the first motor and the second motor based on the position of the first motor detected by the first position sensor and the position of the second motor detected by the second position sensor, so as to control the opening or closing of the first door.

[0010] In some embodiments, the third driving mechanism includes a third motor and a third position sensor; the controller also controls the opening or closing of the first door based on the position of the third motor detected by the third position sensor.

[0011] In some embodiments, the first driving mechanism includes a first motor; the second driving mechanism includes a second motor; the first motor serves as the driving motor, and the second motor serves as the driven motor and moves following the first motor.

[0012] In some embodiments, the third driving mechanism includes a third motor, and the third motor moves following the first motor.

[0013] In some embodiments, the door assembly includes a first connecting rod, a second connecting rod, a third connecting rod, a damping rod and a connector; both ends of the first connecting rod are respectively rotatably connected to the first driving mechanism and the first door; the second driving mechanism is rotatably connected to the second connecting rod; the second connecting rod is further rotatably connected to the third connecting rod, and the third connecting rod is rotatably connected to the first door; the connection position of the third connecting rod and the first door is in front of the connection position of the first connecting rod and the first door; one end of the damping rod is rotatably connected to the first connecting rod, and the other end is rotatably connected to the connector; the connector is rotatably connected to the second connecting rod; during the process of the first door moving from fully closed to not fully opened, the angle between the damping rod and the first connecting rod becomes larger.

[0014] In some embodiments, both the first driving mechanism and the second driving mechanism are connected to the first end of the first door, and the third driving mechanism is connected to the second end of the first door, and the first end and the second end are opposite to each other along the height of the door.

[0015] In some embodiments, at least one of the second driving mechanism and the third driving mechanism includes an electric strut or a cylinder.

[0016] In some embodiments, in the fully closed state of the first door, the front end of the first door is pressed by the rear end of the second door.

[0017] Second aspect, the present application discloses a vehicle. The vehicle includes any one of the foregoing door assemblies.

[0018] For the above-mentioned door assembly and vehicle, since the first door has a non-fully opened state of opening at a first included angle through the cooperation of the first driving mechanism, the second driving mechanism and the third driving mechanism, in this state, the first door is pressed by the second door. On the one hand, the pressing makes the projection of the front end of the first door and the rear end of the second door overlap in a plane along the vehicle body height direction, and the gap between the rear end and the front end is less than a preset value (the preset value makes there be no gap or a very small gap between the rear end and the front end), avoiding the hands of consumers (especially children) being pinched when the first door is in the non-fully opened state. On the other hand, the above settings can also bring a good user experience. For example, when the first door is in the non-fully opened state, looking from the outside towards the inside of the vehicle body, it not only protects the privacy of consumers, but also can hear the outside sound without turning on the car machine, or there is ventilation between the inside of the vehicle body and the outside, etc. Another example is that since the first side door is located inside the second door, opening the second door is not affected by the first door, and because the first door is rotationally connected by the second link and the third link, it can rotate towards the inside of the second door to form the first included angle with the vehicle body when located inside the second door. In this way, opening the first door to the non-fully opened state is not affected by the second door either. Therefore, the first door and the second door can be independently opened and closed, which is convenient to use and also brings a good user experience. Description of the Drawings

[0039] Here, the technical solutions in the embodiments (or "implementation manners") of the present application will be clearly and completely described in conjunction with the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numerals in different drawings represent the same or similar elements.

[0040] If there are terms related to directional indications or positional relationships in the embodiments of the present application (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movement conditions between components in a specific posture (as shown in the accompanying drawings); if this specific posture changes, then the directional indication or positional relationship also changes accordingly. In addition, the terms "first", "second", etc. involved in the embodiments of the present application are only for the purpose of convenient description and cannot be understood as indicating or implying relative importance.

[0041] The present application discloses a vehicle door assembly. Refer to Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 7 , Figure 8 , Figure 10 , Figure 11 , Figure 13 , Figure 14 , Figure 16 and Figure 17, this application discloses a door assembly. The door assembly is applied to a vehicle without a B-pillar and includes a first door 1, a second door 2, a driving mechanism 3 (subsequently referred to as the first driving mechanism 32 and the second driving mechanism 33), and a third driving mechanism 6. Since the vehicle body has no B-pillar, there is an entrance on one side of the vehicle body. When the first door 1 and the second door 2 are fully closed, they close the same entrance on one side of the vehicle along the front-rear direction of the vehicle. That is to say, for a vehicle with a B-pillar, there is a first entrance closed or opened by the front door (such as the second door) and a second entrance closed or opened by the rear door (such as the first door) on one side of the vehicle. After the vehicle has no B-pillar, there is only one entrance on one side of the vehicle, that is, the first entrance and the second entrance are combined into one entrance because there is no B-pillar. Refer to Figure 1 , when the first door 1 and the second door 2 are in a fully closed state, the front end 10 of the first door 1 is located inside the rear end 20 of the second door 2. The inside and outside are referenced with respect to the inside and outside of the vehicle body. The first driving mechanism 32 and the second driving mechanism 33 are finally connected to the bottom of the first door 1, and the third driving mechanism 6 is connected to the top of the first door 1. In some other embodiments, the first driving mechanism 32 and the second driving mechanism 33 are connected to the top of the first door 1, and the third driving mechanism 6 is connected to the bottom of the first door 1. In short, regardless of how the first driving mechanism 32, the second driving mechanism 33, and the third driving mechanism 6 are connected to the first door 1 and their structures, ultimately, the first driving mechanism 32, the second driving mechanism 33, and the third driving mechanism 6 cooperate to drive the first door 1 to achieve three-dimensional motion (motion parallel to the vehicle body direction, motion perpendicular to the vehicle body direction, and swinging), and to achieve full closure or full opening.

[0042] As follows, describe how the related first driving mechanism 32 and second driving mechanism 33 are connected to the first door 1 in an embodiment of this application.

[0043] Refer to Figure 11 , Figure 14 , Figure 16 and Figure 17 , the driving mechanism 3 (the first driving mechanism 32 and the second driving mechanism 33) is connected to the first door 1. Specifically, through Figure 3 and Figure 12The first door connecting member 11 shown is connected to the bottom of the first door 1. The door connecting member 11 belongs to a part of the first door 1 or is fixed to the first door 1 as an independent component. The door assembly further includes a first link 31, a second link 34, a third link 35, a damping rod 36, and a connector 37. Two ends of the first link 31 are respectively rotatably connected to the first driving mechanism 32 and the first door 1. In an embodiment of the present application, it is connected to the door connecting member 11 of the first door 1. The second driving mechanism 33 is rotatably connected to the second link 34. The second link 34 is further rotatably connected to the third link 35, and the third link 35 is rotatably connected to the first door 1. In the present application, it is also connected to the door connecting member 11. A connection point (combining Figure 1 and Figure 3 , still with the front of the vehicle head as the front, using arrow A to represent forward, marking this connection point as the first connection point 111) of the third link 35 and the first door 1 is located in front of a connection point (in Figure 3 , marking this connection point as the second connection point 112) of the first link 31 and the first door 1.

[0044] Referring to Figure 3 , Figure 6 , Figure 9 , Figure 12 , Figure 15 and Figure 18 , one end of the damping rod 36 is rotatably connected to the first link 31, and the other end is rotatably connected to the connector 37. The connector 37 is rotatably connected to the second link 34. Comparing Figure 3 , Figure 6 , Figure 9 , Figure 12 , Figure 15 and Figure 18 it can be seen that during the process of the first door changing from fully closed to not fully opened, the included angle between the damping rod 36 and the first link 31 becomes larger.

[0045] By adopting the first link 31, the first driving mechanism 32, the second driving mechanism 33, the second link 34, the third link 35, the damping rod 36, and the connector 37, the first door and the second door can be independently opened and closed without affecting each other. In addition, by setting the damping rod 36, a relatively small force applied by the first driving mechanism 32 can drive the second driving mechanism 33.

[0046] Referring to Figure 3 , Figure 6 , Figure 9 , Figure 12 , Figure 15 and Figure 18, the third driving mechanism 6 (since there are the first driving mechanism 32 and the second driving mechanism 33 in front, in some embodiments, the third driving mechanism 6 is also called the third motor assembly) is connected to the top of the first door 1 through the second door connecting member 12. The third driving mechanism 6 only needs to cooperate with the driving mechanism 3 to open and close the first door 1, as long as this function can be achieved. In addition, during the opening process of the first door 1, the third driving mechanism 6 can share the weight of the first door 1 to improve the stability and safety during the opening process of the first door 1. In this application, the third driving mechanism 6 is a third motor assembly, including a third motor 611, an electric strut 333, and a connecting rod 62. The connecting rod 62 is rotatably connected to the electric strut 333. The third motor 611 controls the electric strut 333 to extend or retract, and finally, together with the driving mechanism 3, realizes the opening or closing of the first door 1. Figure 6 , Figure 9 , Figure 12 , Figure 15 and Figure 18 illustrate that the electric strut 333 and the connecting rod 62 cooperate to open the first door 1.

[0047] The first driving mechanism 32, the second driving mechanism 33, and the third driving mechanism 6 also cooperate with each other to drive the first door 1 to rotate in the horizontal direction. After rotation, as Figure 5 shown, the first door 1 is in a non-fully opened state; in the non-fully opened state, the front end 10 of the first door 1 is pressed by the rear end 20 of the second door 2, so that the projections of the rear end and the front end in the plane along the vehicle body height direction overlap, and the gap between the rear end and the front end is less than a preset value. Moreover, a first included angle A is formed between the first door 1 and the vehicle body 4. The pressing connection can be a direct contact without a gap for pressing connection, or a small gap can be formed. The preset value can be set according to the situation to achieve the subsequent function of not pinching hands. It is not limited by what structure realizes the pressing connection, as long as the role played by the subsequent pressing connection can be achieved.

[0048] See Figure 3 , Figure 6 , Figure 9 , Figure 12 , Figure 15 and Figure 18 and in combination with Figure 2 , Figure 5 , Figure 8 , Figure 11 , Figure 14 and Figure 17 , the working principle of the driving mechanism 3 (the first driving mechanism 32 and the second driving mechanism 33) driving the first door 1 is described as follows:

[0049] The first driving mechanism 32 and the second driving mechanism 33 are arranged on the vehicle body 4. The motor of the first driving mechanism 32 (subsequently referred to as the first motor 321) can rotate clockwise or counterclockwise, thereby driving the first connecting rod 31 to rotate. When the first motor 321 rotates clockwise, the first vehicle door 1 is closed, and when it rotates counterclockwise, the first vehicle door 1 is opened. The second driving mechanism 33 can extend or contract. During the extension or contraction process, the first vehicle door 1 rotates around the structure formed by the second connecting rod 34 and the third connecting rod 35 (at this time, the second connecting rod 34 and the third connecting rod 35 can be regarded as a whole). At the same time, the relationship between the second connecting rod 34 and the third connecting rod 35 will show changes as Figure 3 and Figure 6 and Figure 9 and Figure 12 and Figures 15 to 18 shown. Finally, through the aforementioned driving mechanism 3, the first vehicle door 1 is realized to move from Figure 1 and Figure 2 shown in the fully closed state to Figure 16 and Figure 17 shown in the fully open state, or from the fully open state to the fully closed state.

[0050] In addition, the driving mode of the third driving mechanism 6 can also refer to the driving modes of the first driving mechanism 32 and the second driving mechanism 33, or the following driving mode as described later.

[0051] It should be noted that Figure 7 、 Figure 8 、 Figure 10 、 Figure 11 、 Figure 13 and Figure 14 indicate some intermediate states (non-fully open states) when the first vehicle door 1 is opened. Those skilled in the art can understand that in some cases, these intermediate states may not exist.

[0052] With the above settings, the first door 1 is made to have a non-fully opened state with a first included angle by the cooperation of the driving mechanism 3 (the first driving mechanism 32 and the second driving mechanism 33) and the third driving mechanism 6. In this state, the first door 1 is pressed against by the second door 2. On the one hand, this pressing makes the front end 10 of the first door 1 and the rear end 20 of the second door 2 overlap in the projection in the plane along the vehicle body height direction, and the gap between the rear end 20 and the front end 10 is less than a preset value (the preset value makes there be no gap or a very small gap between the rear end 20 and the front end 10), avoiding the hands of consumers (especially children) being pinched when the first door 1 is in the non-fully opened state. On the other hand, the above settings can also bring a good user experience. For example, when the first door 1 is in the non-fully opened state, looking from the outside towards the inside of the vehicle body 4, the visible range inside the vehicle body is small, which not only protects the privacy of consumers, but also allows one to hear the outside sounds without turning on the car machine, or there is ventilation between the inside of the vehicle body 4 and the outside, etc. Also, for example, because the first side door is located inside the second door, opening the second door is not affected by the first door. And because the first door 1 is rotationally connected by the second link and the third link, it can rotate towards the inside of the second door when located inside the second door to form the first included angle A with the vehicle body. In this way, opening the first door 1 to the non-fully opened state is not affected by the second door either. Therefore, the first door 1 and the second door 2 can be independently opened and closed, which is convenient to use and also brings a good user experience.

[0053] In some embodiments, the preset value is a, where 0 cm ≤ a ≤ 1 cm. Thereby, pinching can be prevented.

[0054] See Figure 19 and in combination with Figure 5 , first of all, it should be noted that although Figure 19 the A shown schematically looks larger than Figure 5 the A shown in Figure 19 , the first included angle A, the second included angle B and the angle C in Figure 5 are only used to indicate the size relationship between them and are not used to limit the angle shown in Figure 5 . The driving mechanism 3 also drives the first door 1 to form a second included angle B with the vehicle body 4. C ≤ B < A, where the angle C is the lower limit angle when the second door 2 presses against the first door 1 when the door is not fully opened, and the first included angle A can be considered as the upper limit angle when the second door 2 presses against the first door 1 in the non-fully opened state. For a vehicle, usually, when leaving the factory, the first included angle A and the angle C are fixed values. The B is a value between A and C, that is, consumers can rotate the first door within the range of the angle C and the first included angle A and fix the door at the rotated angle.

[0055] With the above settings, since the first door 1 can also swing between the first included angle A and the angle C, the opening angle of the first door 1 in a non-fully opened state can be adjusted, thereby bringing a better user experience. For example, during use, consumers can adjust the opening angle of the first door 1 according to the strength of the external wind. For example, if the external wind is too strong, the first included angle A can be adjusted to a smaller angle B.

[0056] In some embodiments, the door assembly includes a controller 5, which is connected to the first driving mechanism 32, the second driving mechanism 33, and the third driving mechanism 6, and drives the first door 1 to switch between the first included angle A, the second included angle B, and the angle C.

[0057] With such a setting, by controlling the first driving mechanism 32, the second driving mechanism 33, and the third driving mechanism 6 through the controller, the first door can be switched between the first included angle A, the second included angle B, and the angle C, which is convenient to control and provides a good user experience in terms of angle switching.

[0058] Based on the functions of the foregoing driving mechanisms 3 (the first driving mechanism 32 and the second driving mechanism 33) and the third driving mechanism 6, those skilled in the art can understand that the structures of the driving mechanisms 3 (the first driving mechanism 32 and the second driving mechanism 33) and the third driving mechanism 6 are not limited, as long as the foregoing functions can be achieved.

[0059] See Figure 20 and in combination with Figure 3 、 Figure 6 、 Figure 9 、 Figure 12 、 Figure 15 and Figure 18 , the door assembly includes a controller 5. The first driving mechanism 32 includes a first motor 321 and a first position sensor 322. The second driving mechanism 33 includes a second motor 331 and a second position sensor 332.

[0060] The controller 5 controls the first motor 321 and the second motor 331 based on the position of the first motor 321 detected by the first position sensor 322 and the position of the second motor 331 detected by the second position sensor 332 to open the first door 1. Compare Figure 3 、 Figure 6 、 Figure 9 、 Figure 12 、 Figure 15 and Figure 18It can be seen that by controlling the first driving mechanism 32 and the second driving mechanism 33, the first connecting rod 31, the first driving mechanism 32, the second driving mechanism 33, the second connecting rod 34, the third connecting rod 35, the damping rod 36, the connecting head 37 and the door connecting member 11 of the first door 1 enclose different shapes, thereby corresponding to different opening states of the first door 1. Of course, for controlling the closing of the first door 1, it can also be achieved according to the positions of the first motor 321 and the second motor 331. In the embodiment of the present application, the positions of the first motor 321 and the second motor 331 are the positions of the motor rotation, or the position stroke, etc., and are not limited thereto.

[0061] With the above settings, it can be achieved by a single controller 5, or simultaneously achieved by multiple controllers synchronously (for example, the first controller is responsible for collecting the position information of the assembly and controlling the first motor 321, and the second controller is responsible for collecting the position information of the assembly and controlling the second motor 331. The two controllers synchronize the motor states in real time through bus information to achieve control. Whether using a single controller 5 or multiple controllers, the opening and closing of the first door 1 can be achieved through electric control, and the operation is simple.

[0062] See Figure 20 , in some embodiments, the third driving mechanism 6 includes a third motor 611 and a third position sensor 612; the controller 5 also controls the opening or closing of the first door 1 based on the position of the third motor 611 detected by the third position sensor 612. The position of the third motor 611 can be understood with reference to the positions of the first motor 321 and the second motor 331, and will not be elaborated here.

[0063] In some embodiments, the first motor 321 is used as the active motor, and the second motor 331 is used as the driven motor, following the movement of the first motor 321, so that the position of the second motor 331 changes dynamically with the change of the position of the first motor 321.

[0064] With the above settings, since the second motor 331 is used as the driven motor and follows the movement of the first motor 321, further, during the process of jointly driving the first door 1 to open or close by the first driving mechanism 32 and the second driving mechanism 33, the opening or closing is smoother. The so-called following is not in the strict sense of active and driven, stopping when the main one stops and the driven one stops. The so-called following can be understood in a broad sense as: as mentioned above, the position of the slave motor (the second motor 331) needs to change dynamically following the position of the main motor (the first motor 321), or when the main motor (the first motor 321) is in certain fixed position intervals, the position of the slave motor (the second motor 331) remains unchanged.

[0065] With the above settings, the second motor 331 is driven by the first motor 321, and thus, the opening or closing of the first door 1 is smoother.

[0066] In some embodiments, the third motor 611 of the third driving mechanism 6 moves following the first motor 321. Combining Figure 3 、 Figure 6 、 Figure 9 、 Figure 12 、 Figure 15 and Figure 18 , it can be understood that during the opening process of the first door 1 corresponding to the third driving mechanism 6, the states of the relevant components of the third driving mechanism 6 can be understood from the above movement process. Here, the meaning of "following" is understood with reference to the aforementioned second motor 331 following the first motor 321.

[0067] With the above settings, both the third motor 611 of the third driving mechanism 6 and the second motor 331 are driven by the first motor 321, and thus, the opening or closing of the first door 1 is smoother.

[0068] In some embodiments, the second driving mechanism 33 includes an electric strut 333 or a cylinder.

[0069] With the above settings, the electric strut or the cylinder makes the structure of the second driving mechanism 33 simple and easy to control.

[0070] See Figure 3 、 Figure 6 、 Figure 9 、 Figure 12 、 Figure 15 and Figure 18 , in some embodiments, the third driving mechanism 6 (the third motor assembly in some embodiments) includes an electric strut 333 or a cylinder.

[0071] With the above settings, the third driving mechanism including an electric strut or a cylinder can make the structure of the door assembly of the present application simple and easy to control. In short, it is sufficient that at least one of the third driving mechanism 6 and the second driving mechanism 33 includes the electric strut 333 or the cylinder.

[0072] In some embodiments, in the fully closed state of the first door 1, the front end 10 of the first door 1 is pressed by the rear end 20 of the second door 2.

[0073] With the above settings, in the fully closed state, the front end 10 of the first door 1 is pressed by the rear end 20 of the second door 2, and there is no gap or a very small gap between the front end 10 of the first door 1 and the rear end 20 of the second door 2, preventing the hands of consumers (especially children) from being pinched when the first door is in the fully closed state. Furthermore, in the cases of opening the first included angle and fully closing, the hands of consumers will not be pinched. Of course, in some other embodiments, when the first door 1 is fully closed and located inside the second door 2, the front end 10 of the first door 1 is not pressed by the rear end 20 of the second door 2.
