Description

Technical Field

[0001] The present application relates to the technical field of automobile doors, and in particular to an automobile door and a vehicle. Background Art

[0002] An electric door is an automotive component that uses an electric drive system to automatically open and close the door. It is widely used in high-end car models and electric vehicles.

[0003] Announcement No. CN205591729U discloses a car door and a car, including a door body, a door shaft, which is arranged on one side of the door body, and the door body is connected to rotate around the door shaft; a door shaft motor, which is connected to the door shaft, and the door shaft motor drives the door shaft to rotate; a body controller, which is electrically connected to the door shaft motor; and a control button, which is electrically connected to the body controller, and the control button includes an open state and a closed state. When the control button is in the open state, the body controller drives the door shaft motor to rotate, thereby driving the door shaft to rotate in a first direction to drive the door body to open; when the control button is in the closed state, the body controller drives the door shaft motor to rotate, thereby driving the door shaft to rotate in a second direction to drive the door body to close.

[0004] During use, the above-mentioned car doors need to be opened in a fan-shaped manner, which occupies a large opening angle. In a restricted use environment, the doors are difficult to open and close completely, which has limitations in use and affects the convenience of passengers entering and exiting the vehicle. Utility Model Content

[0005] In order to help solve the problem that existing automobile doors need to occupy a large angle when opening and closing in a fan shape, making it difficult for passengers to enter and exit the vehicle conveniently in a compact space, and having great limitations on use, the present application provides an automobile door, which adopts the following technical solution: it includes a frame and a door arranged on one side of the frame, and also includes a transmission unit, a first end of the transmission unit is rotatably connected to the frame, and a second end of the transmission unit is rotatably connected to the door, a driving unit is provided on the frame, and the driving unit is connected to the first end of the transmission unit for driving the transmission unit to rotate relative to the frame, and a telescopic unit is also provided on the frame, and the telescopic unit is connected to the door for controlling the opening and closing trajectory of the door.

[0006] Through the above technical solution, the drive unit is activated, which drives the door through the transmission unit, achieving deflection relative to the frame. The telescopic unit controls the door's opening and closing trajectory, pushing the door to adjust its angle. This deflection-based opening and closing method reduces the space occupied by the door during opening and closing, meeting the needs of door opening and closing in compact spaces, facilitating passenger entry and exit, and improving user comfort and convenience.

[0007] In a specific possible implementation scheme, the transmission unit includes a connecting rod and a bottom rod arranged opposite to each other, one end of the connecting rod is rotatably connected to the vehicle door, and the other end of the connecting rod away from the vehicle door is fixedly connected to the output end of the drive unit, one end of the bottom rod is rotatably connected to the vehicle door, and the other end of the bottom rod away from the vehicle door is rotatably connected to the frame.

[0008] Through the above technical solution, the drive unit is started, which drives the connecting rod at the output end of the drive unit to move, thereby driving the door connected to the connecting rod to move. The connecting rod and the bottom rod provide guidance and stabilization for the movement of the door, so that the power of the drive unit can be accurately and smoothly transmitted to the door, realizing smooth opening and closing of the door.

[0009] In a specific possible implementation manner, the bottom rod and the connecting rod are connected via a plurality of reinforcing rods.

[0010] Through the above technical solution, after the bottom rod and the connecting rod are connected by the reinforcing rod, the overall structural strength can be increased, which helps to resist external impact and vibration, reduce the deformation or damage of the door caused by external force, and improve the firmness and stability of the door during operation.

[0011] In a specific embodiment, the distance between the connecting rod and the bottom bar close to the vehicle door is smaller than the distance between the connecting rod and the bottom bar close to the frame.

[0012] Through the above technical solution, the space occupied by the connecting rod and the bottom rod is reduced, which makes it easier to reserve space for mechanisms such as the handle and storage box on the inside of the door, thereby improving the space utilization between the door and the frame.

[0013] In a specific embodiment, the reinforcing rod close to the frame may be cross-disposed between the connecting rod and the bottom rod.

[0014] Through the above technical solution, the cross-arranged reinforcement rods can effectively connect the connecting rod and the bottom rod together, disperse the stress in multiple directions, reduce the concentration of stress in specific areas, and improve the stability and bearing capacity of the overall structure.

[0015] In a specific embodiment, a reinforcement bar close to the vehicle door may be arranged in parallel between the connecting rod and the bottom bar.

[0016] Through the above technical solution, the parallel reinforcement rods can improve the structural rigidity, reduce the deformation or damage between the connecting rod and the bottom rod under the action of external force, and thus reduce the possibility of the door being squeezed and deformed.

[0017] In a specific possible implementation scheme, the driving unit includes a fixing frame provided on the frame, an actuator is provided on the fixing frame, and an output end of the actuator is fixedly connected to the transmission unit.

[0018] Through the above technical solution, the actuator is started, and the actuator output power drives the transmission unit at the output end of the actuator to rotate, thereby realizing the deflection movement of the car door.

[0019] In a specific feasible implementation scheme, the telescopic unit includes a telescopic cylinder, a first connecting frame and a second connecting frame, the first connecting frame is fixed on the vehicle door, the second connecting frame is fixed on the frame, one end of the telescopic cylinder is rotatably connected to the second connecting frame, and the output end of the telescopic cylinder is rotatably connected to the first connecting frame.

[0020] Through the above technical solution, the telescopic cylinder is started to drive the first connecting frame at the output end of the telescopic cylinder to move, thereby driving the car door to move, controlling the running trajectory of the car door, and realizing the adjustment of the opening and closing state of the car door.

[0021] In a specific possible implementation manner, when there are two vehicle doors, one of the vehicle doors is provided with a main locking mechanism, and the main locking mechanism is used to lock the two vehicle doors to each other when they are in a closed state.

[0022] Through the above technical solution, when there are two doors, the main locking mechanism is used to lock the two doors in the closed state, while saving the B-pillar between the two doors in the existing vehicle, thereby increasing the space for passengers to enter and exit the vehicle.

[0023] In a specific embodiment, a vehicle is also disclosed, comprising the above-mentioned automobile door.

[0024] In summary, this application has the following beneficial technical effects:

[0025] (1) Start the drive unit, which drives the door through the transmission unit to achieve deflection of the door relative to the frame. The telescopic unit controls the door's opening and closing trajectory and pushes the door to adjust its angle. By opening and closing the door after deflection, the space occupied by the door during the opening and closing process is reduced, meeting the door opening and closing requirements in a compact space, making it easier for passengers to enter and exit the vehicle, and improving user comfort and convenience.

[0026] (2) When there are two doors, the main locking mechanism can be used to lock the two doors in the closed state, which can save the B-pillar between the two doors in the existing vehicle and increase the space for passengers to enter and exit the vehicle. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] The following is combined with Figure 1-2 This application is described in further detail.

[0031] The embodiments of the present application disclose a car door and a car.

[0032] Example 1

[0033] Reference Figure 1 The automobile door includes a frame 100 and a door 200 arranged on one side of the frame 100. In the embodiment of the present application, two doors 200 are located on the same side of the frame 100 as an example. A main locking mechanism is installed on one of the doors 200. The main locking mechanism is used to lock the two doors 200 with each other when they are in a closed state. In the embodiment of the present application, the main locking mechanism can adopt an electric motor automatic door lock.

[0034] Reference Figure 1 The automobile door further includes a transmission unit 300, a first end 340 of which is rotatably connected to the frame 100, and a second end 350 of which is rotatably connected to the door 200. A drive unit 400 is provided on the frame 100, and an output end of the drive unit 400 is connected to the first end 340 of the transmission unit 300, for driving the transmission unit 300 to rotate relative to the frame 100. The frame 100 is further provided with a telescopic unit 500, which is connected to the door 200 and is used to control the opening and closing trajectory of the door 200. Preferably, when the drive unit 400 and the telescopic unit 500 are activated, the main locking mechanism is simultaneously activated to unlock.

[0035] Reference Figure 1 When the driving unit 400 and the telescopic unit 500 are started synchronously, the door 200 opens and closes parallel to the frame 100. Compared with the existing fan-shaped opening and closing method of the door 200, the door 200 opens and closes parallel to the frame 100, which saves the space required for opening and closing the door 200.

[0036] Reference Figure 1The transmission unit 300 includes a connecting rod 310, one end of which is rotatably connected to the vehicle door 200 via a pin. The end of the connecting rod 310 facing away from the vehicle door 200 is fixedly connected to the output end of the drive unit 400. The transmission unit 300 also includes a bottom bar 320, one end of which is rotatably connected to the vehicle door 200, and the end of the bottom bar 320 facing away from the vehicle door 200 is rotatably connected to the frame 100. The bottom bar 320 and the connecting rod 310 are connected by a plurality of reinforcing rods 330. The connection between the bottom bar 320 and the connecting rod 310 by the reinforcing rods 330 increases the overall structural strength, helps to resist external impact and vibration, reduces deformation or damage to the vehicle door 200 caused by external forces, and improves the firmness and stability of the vehicle door 200 during operation.

[0037] Therefore, the driving unit 400 is started, which drives the connecting rod 310 at the output end of the driving unit 400 to move, thereby driving the vehicle door 200 connected to the connecting rod 310 to move. The connecting rod 310 provides guidance and stabilization for the movement of the vehicle door 200, so that the power of the driving unit 400 can be accurately and smoothly transmitted to the vehicle door 200, thereby realizing smooth opening and closing of the vehicle door 200.

[0038] Reference Figure 1 The reinforcing rods 330 near the frame 100 can be arranged crosswise between the connecting rod 310 and the bottom rod 320, while the reinforcing rods 330 near the door 200 can be arranged parallel to the connecting rod 310 and the bottom rod 320. The cross-arranged reinforcing rods 330 effectively connect the connecting rod 310 and the bottom rod 320, dispersing stress in multiple directions, reducing stress concentration in specific areas, and improving the stability and load-bearing capacity of the overall structure. The parallel arrangement of the reinforcing rods 330 can increase structural rigidity and reduce deformation or damage between the connecting rod 310 and the bottom rod 320 under external forces, thereby reducing the possibility of compression and deformation of the door 200.

[0039] Reference Figure 1 The distance between the connecting rod 310 and the bottom rod 320 near the vehicle door 200 is smaller than the distance between the connecting rod 310 and the bottom rod 320 near the frame 100, reducing the space occupied by the connecting rod 310 and the bottom rod 320, making it easier to reserve space for components such as the handle and storage box on the inside of the vehicle door 200, thereby improving the space utilization between the vehicle door 200 and the frame 100.

[0040] Reference Figure 1The drive unit 400 includes a mounting bracket 410 mounted on the frame 100. An actuator 420 is mounted on the mounting bracket 410. The output end of the actuator 420 is fixedly connected to the transmission unit 300. Therefore, when the actuator 420 is activated, the power output from the actuator 420 drives the output shaft of the actuator 420 to rotate. Since the end of the connecting rod 310 away from the vehicle door 200 is fixedly connected to the output end of the actuator 420, the connecting rod 310 is driven to move, thereby achieving the deflection movement of the vehicle door 200.

[0041] Reference Figure 1 The telescopic unit 500 includes a telescopic cylinder 510, a first connecting frame 520, and a second connecting frame. The first connecting frame 520 is fixed to the vehicle door 200, and the second connecting frame is fixed to the frame 100. One end of the telescopic cylinder 510 is rotatably connected to the second connecting frame, and the output end of the telescopic cylinder 510 is rotatably connected to the first connecting frame 520. In this embodiment of the present application, the telescopic cylinder 510 can be an electric telescopic cylinder. Therefore, when the telescopic cylinder 510 is activated, the first connecting frame 520 at the output end of the telescopic cylinder 510 moves, thereby moving the vehicle door 200, controlling the movement trajectory of the vehicle door 200 and adjusting the opening and closing state of the vehicle door 200.

[0042] In addition, in the embodiment of the present application, a four-link motion structure 310 is used to realize the opening and closing of the vehicle door 200. While locking the two vehicle doors 200 in the closed state through the electric motor-type automatic door lock, the B-pillar between the two doors 200 in the existing vehicle can be saved, thereby increasing the space for passengers to enter and exit the vehicle and improving space utilization.

[0043] The operating principle of the embodiment of the present application is as follows: actuator 420 is activated, and the power output by actuator 420 drives the connecting rod 310 at the output end of actuator 420 to rotate, thereby achieving movement of vehicle door 200; telescopic cylinder 510 is activated, which drives the first connecting frame 520 at the output end of telescopic cylinder 510 to move, thereby driving the movement of vehicle door 200, controlling the movement trajectory of vehicle door 200, and adjusting the opening and closing state of vehicle door 200. When actuator 420 and telescopic cylinder 510 are activated synchronously, vehicle door 200 opens and closes parallel to frame 100. Compared with the existing fan-shaped opening and closing method of vehicle door 200, opening and closing vehicle door 200 parallel to frame 100 saves space required for opening and closing vehicle door 200. Even in restricted operating environments, vehicle door 200 can be fully opened and closed parallel to frame 100, facilitating passenger entry and exit while minimizing limitations.

[0044] Example 2

[0045] Reference Figure 2It should be noted that the difference between the second embodiment of the present application and the first embodiment is that when the drive unit 400 and the telescopic unit 500 are activated asynchronously, the drive unit 400 drives one end of the door 200 to deflect away from the frame 100, and the door 200 opens and closes at an angle with the frame 100. If there is an obstacle on the side of the door 200 facing away from the frame 100, the drive unit 400 can drive the door 200 to deflect to avoid the obstacle. At the same time, it meets the requirements of opening and closing the door 200 in a compact space, making it easier for passengers to enter and exit the vehicle, and improving user comfort and convenience.

[0046] By adjusting the start-up sequence of the driving unit 400 and the telescopic unit 500, two opening and closing states can be achieved: parallel opening and closing between the door 200 and the frame 100, and angled opening and closing between the door 200 and the frame 100. This provides greater flexibility and improves the applicability of the entire automobile door.

[0047] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
