Description

Technical Field

[0001] This application belongs to the field of automotive technology, specifically relating to door systems, door control methods, and automobiles. Background Technology

[0002] Current car door designs often use external handles, which can generate wind noise during driving. While existing electric vehicles use electric hinges and millimeter-wave radar to open and close the doors, this design is costly due to the radar; furthermore, the radar may give false alarms, posing a risk of fingers getting caught during door opening or closing. Summary of the Invention

[0003] One objective of this application is to provide a vehicle door system that can better avoid the risk of "hand pinching" during the opening or closing of the vehicle door.

[0004] Another objective of this application is to provide a door control method that can be used to control the aforementioned door system.

[0005] One inventive objective of this application is to provide an automobile that may include the aforementioned door system.

[0006] According to an embodiment of this application, a first aspect provides a door system for a vehicle, the vehicle including a vehicle body, the door system comprising:

[0007] A car door, one side of which is hinged to the vehicle body;

[0008] A door lock mechanism is disposed between the vehicle body and the door, and the door lock mechanism controls the locking and unlocking of the door;

[0009] An unlocking mechanism is provided on the vehicle door, the unlocking mechanism is connected to the door lock mechanism, and the unlocking mechanism can control the door lock mechanism to unlock the vehicle door;

[0010] An ejection mechanism is disposed on the vehicle body. The ejection mechanism can be controlled to reciprocate along a first direction and the opposite direction of the first direction. When the ejection mechanism moves along the first direction, the unlocking mechanism controls the door lock mechanism to unlock the vehicle door. When the ejection mechanism moves along the first direction, it pushes the vehicle door to rotate around the vehicle body.

[0011] An angle detection module is installed in the vehicle door, and the angle detection module is used to obtain the angle between the vehicle door and the vehicle body;

[0012] A door controller is disposed on the vehicle body. The door controller is electrically connected to the ejector mechanism and the angle detection module. The door controller can control the ejector mechanism to move along the first direction and can control the ejector mechanism to move in the opposite direction of the first direction according to the angle information obtained by the angle detection module.

[0013] In one embodiment, the door lock mechanism includes a latch and a bolt, the latch being disposed on the vehicle body, the bolt being disposed on the vehicle door, and the unlocking mechanism being connected to the bolt and controlling the bolt to separate from the latch to unlock the vehicle door.

[0014] In one embodiment, the unlocking mechanism includes a spring-loaded rotating part and a limiting part. The spring-loaded rotating part is rotatably disposed on the vehicle door, and a cable is provided between the spring-loaded rotating part and the locking tongue. The limiting part is disposed on the spring-loaded rotating part and is used to restrict the rotation of the spring-loaded rotating part.

[0015] When the ejector mechanism moves along the first direction, it pushes the spring-loaded rotating part to rotate around the second direction. The spring-loaded rotating part separates the latch from the buckle through the cable. When the ejector mechanism separates from the spring-loaded rotating part, the spring-loaded rotating part moves in the opposite direction of the second direction and causes the latch to engage with the buckle.

[0016] In one embodiment, the ejection mechanism includes a top column and a driving element, the driving end of the driving element being connected to the top column, and the driving element being able to control the top column to reciprocate along the first direction and the opposite direction of the first direction.

[0017] In one embodiment, the travel distance of the top column includes a first travel segment and a second travel segment. The top column controls the unlocking mechanism to work in the first travel segment, and the unlocking mechanism causes the door lock mechanism to unlock the vehicle door. The top column controls the vehicle door to rotate around the vehicle body in the second travel segment.

[0018] In one embodiment, the driving element is a motor.

[0019] In one embodiment, the door controller includes a touch switch disposed on the vehicle body, the touch switch being capable of controlling the ejection mechanism to move along the first direction.

[0020] In one embodiment, the angle detection module includes a micro switch, which can send a signal to the door controller, causing the door controller to control the ejection mechanism to move in the opposite direction of the first direction.

[0021] According to an embodiment of this application, a second aspect provides a door control method for controlling the door system, the door control method comprising the following steps:

[0022] The door controller controls the ejection mechanism to move along the first direction. When the ejection mechanism moves along the first direction, it causes the unlocking mechanism to activate. The unlocking mechanism controls the door lock mechanism to unlock the door. When the ejection mechanism moves along the first direction, it pushes the door to rotate around the vehicle body. After the ejection mechanism moves along the first direction to its maximum stroke, the ejection mechanism maintains its current state.

[0023] The angle between the door and the vehicle body is obtained by the angle detection module. When the angle between the door and the vehicle body exceeds a preset first threshold, the door controller controls the ejection mechanism to move in the opposite direction of the first direction through the signal sent by the angle detection module.

[0024] According to an embodiment of this application, a third aspect provides an automobile that includes the door system.

[0025] In the vehicle door system of this application, the door controller controls the ejector mechanism to move along a first direction. The ejector mechanism controls the unlocking mechanism, which unlocks the door. The ejector mechanism continues to move along the first direction to complete the action of pushing the door open, and the ejector mechanism maintains its current state. The angle detection module obtains the angle between the door and the vehicle body, and the door control module causes the ejector mechanism to move in the opposite direction of the first direction based on the angle information obtained by the angle detection module. In this application, the door controller controls the ejector mechanism to move in the opposite direction of the first direction based on the angle between the door and the vehicle body. That is, the ejector mechanism only moves in the opposite direction of the first direction when the angle between the door and the vehicle body meets the requirements, thus effectively avoiding the "hand pinching" situation. In addition, the ejector mechanism of this application can also control the unlocking mechanism to complete the action of unlocking the door. Attached Figure Description

[0033] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0034] It should be noted that the illustrations provided in this embodiment are only schematic representations of the basic concept of the present invention.

[0035] The structures, proportions, sizes, etc., illustrated in the accompanying drawings of this specification are only for the purpose of assisting those skilled in the art in understanding and reading the content disclosed in the specification, and are not intended to limit the conditions under which the present invention can be implemented.

They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0037] Existing automobiles use external handles in their door designs, which can generate wind noise during driving. While current electric vehicles use electric hinges and millimeter-wave radar to open and close the doors, this design is costly due to the radar; furthermore, the radar may produce false alarms, posing a risk of hand pinching during door closing. To better address this issue, researchers have proposed a door system comprising a push-out mechanism and an angle detection module. The push-out mechanism remains in its current state after the door is pushed open, and only retracts when the angle detection module detects that the angle between the door and the vehicle body meets the requirements, thus effectively avoiding the risk of hand pinching. It should be noted that during the process of opening the door, passengers may rotate the door, increasing the angle between the door and the vehicle body. When the angle between the car door and the vehicle body meets the requirements, it can be understood that the angle between the door and the vehicle body is large enough. In this case, there is no risk of passengers getting their hands caught while opening the door due to an excessively small angle. The door system in this application can be applied to the automotive field, but it is not limited to it; it can also be applied to other solutions involving the opening or closing of doors and the vehicle body.

[0038] like Figure 1 As shown, Figure 1 This is a schematic diagram of the door system in one embodiment of this application. Figure 2 This is a schematic diagram of the structure of a door system according to one embodiment of this application. The door system of this application can be used in a vehicle, wherein the vehicle includes a vehicle body 100. The door system includes: a door 200, a door locking mechanism 300, an unlocking mechanism 400, a push-out mechanism 500, an angle detection module 600, and a door system door controller 700.

[0039] In this context, the vehicle body 100 can be understood as the frame itself. The door 200 can be hinged to the vehicle body 100, for example, one side of the door 200 can be hinged to the vehicle body 100. The hinge method can include mechanical or electric hinges. In a mechanical hinge, the door 200 requires external force to close. An electric hinge, on the other hand, uses an electric device to drive the door 200 to rotate around the vehicle body 100, thus opening or closing the door.

[0040] The door lock mechanism 300 can lock and unlock the door 200 to the vehicle body 100. The door lock mechanism 300 can operate electromagnetically or by a latch, thus achieving the locking and unlocking of the door 200 to the vehicle body 100. The unlocking mechanism 400 can be understood as unlocking the door lock mechanism 300, allowing the door 200 to be opened. The unlocking mechanism 400 can be understood as controlling the door lock mechanism 300 by, for example, controlling electromagnetic contacts or a latch-type bolt. During its movement, the ejector mechanism 500 can activate the unlocking mechanism 400, for example, by causing the unlocking mechanism 400 to move or rotate. The unlocking mechanism 400's action causes the door lock mechanism 300 to actuate, thereby opening the door 200. As the ejector mechanism 500 continues to move, it can push the door 200, causing the door 200 to rotate around the vehicle body 100. The angle detection module 600 can be used to obtain the angle between the door 200 and the vehicle body 100, thereby obtaining the current state of the door 200. The angle detection module 600 can directly obtain the angle information between the door 200 and the vehicle body 100 through a sensor, or it can convert displacement transformation into angle change through a displacement sensor, for example. After the angle sensor obtains the angle information between the door 200 and the vehicle body 100, it can send a signal to the door controller 700, thereby causing the door controller 700 to control the retraction of the ejection mechanism 500.

[0041] The concept of this embodiment is as follows: during the opening of the car door 200, the door controller 700 controls the movement of the ejector mechanism 500. During the movement of the ejector mechanism 500, it controls the action of the unlocking mechanism 400. When the unlocking mechanism 400 completes its action, it causes the door lock mechanism 300 to unlock the car door 200. As the ejector mechanism 500 continues to move, it pushes the car door 200 to rotate around the vehicle body 100. When the ejector mechanism 500 reaches its maximum travel, it maintains its current state. Because the ejector mechanism 500 maintains its maximum travel, meaning the car door 200 and the vehicle body 100 are supported by the ejector mechanism 500, the gap between the car door 200 and the vehicle body 100 will not be reduced. Passengers can insert their fingers into the gap between the car door 200 and the vehicle body 100 during the opening process without being pinched due to a reduced gap. As the vehicle door 200 is opened by a passenger, the angle between the door 200 and the vehicle body 100 continues to increase. When the angle reaches a preset threshold, the angle detection module 600 sends a signal, causing the door controller 700 to retract the ejector mechanism 500 to prevent a collision between the ejector mechanism 500 and the door 200 during the closing process. In other words, when a passenger moves the door 200, the ejector mechanism 500 restricts the gap between the door 200 and the vehicle body 100, preventing the passenger from getting their hand caught.

[0042] Specifically, a door lock mechanism 300 is located between the vehicle body 100 and the door 200, controlling the locking and unlocking of the door 200. An unlocking mechanism 400 is located on the door 200, connected to the door lock mechanism 300, and capable of controlling the door lock mechanism 300 to unlock the door 200. A push-out mechanism 500 is located on the vehicle body 100, capable of being controlled to reciprocate along a first direction and the opposite direction. The first direction can be referred to... Figure 2 In the direction pointed to by the middle arrow a, the ejector mechanism 500 moves along the first direction, causing the unlocking mechanism 400 to control the door lock mechanism 300 to unlock the door 200. When the ejector mechanism 500 continues to move along the first direction, it can push the door 200 to rotate around the vehicle body 100. It should be noted that the first direction can be a linear motion direction or a curved motion direction, which can be implemented according to actual needs.

[0043] An angle detection module 600 is disposed on the door 200, and is used to obtain the angle between the door 200 and the vehicle body 100. A door controller 700 is disposed on the vehicle body 100, and is electrically connected to the ejector mechanism 500 and the angle detection module 600. The door controller 700 can control the ejector mechanism 500 to move along a first direction, and can also control the ejector mechanism 500 to move in the opposite direction of the first direction based on the angle information obtained by the angle detection module 600.

[0044] In this embodiment, when the car door 200 is opened, the door controller 700 controls the ejection mechanism 500 to operate, allowing the ejection mechanism 500 to move along a first direction. During this movement, the ejection mechanism 500 triggers the unlocking mechanism 400 to control the door lock mechanism 300 to unlock the car door 200. After the door lock mechanism 300 unlocks the car door 200, the ejection mechanism 500 continues to move along the first direction, thus pushing the car door 200 open. It should be noted that after the car door 200 is pushed open, the ejection mechanism 500 maintains its current state to prevent the gap between the car door 200 and the vehicle body 100 from narrowing, which could lead to a "hand pinch" risk. Simultaneously, the angle between the car door 200 and the vehicle body 100 can be detected by the angle detection module 600. When the angle between the car door 200 and the vehicle body 100 reaches a set threshold, the door controller 700 can control the ejection mechanism 500 to move in the opposite direction of the first direction, allowing the car door 200 to close smoothly. In this application, the door 200 is opened by the cooperation of the ejection mechanism 500, the unlocking mechanism 400, and the door lock mechanism 300. At the same time, during the opening of the door 200, the ejection mechanism 500 ensures that the gap between the door 200 and the vehicle body 100 does not decrease, thus effectively avoiding the problem of "hand pinching". In addition, the cooperation between the ejection mechanism 500, the angle detection module 600, and the door controller 700 also ensures that the door 200 will not collide with the ejection mechanism 500 during the closing process.

[0045] In one embodiment, the door lock mechanism 300 includes a latch and a bolt. The latch is disposed on the vehicle body 100, and the bolt is disposed on the door 200. The unlocking mechanism 400 is connected to the bolt and controls the bolt to separate from the latch to unlock the door 200. In this embodiment, when the unlocking mechanism 400 is activated, for example, during the movement or rotation of the unlocking structure, the unlocking mechanism 400 can separate the bolt from the latch. When the bolt and latch are separated, it can be understood that the door 200 is unlocked; and when the bolt and latch are engaged, it can be understood that the door 200 is locked.

[0046] Furthermore, in one embodiment, see [reference] Figure 2As shown, the unlocking mechanism 400 includes a spring-loaded rotating part 410 and a limiting part 420. The spring-loaded rotating part 410 is rotatably mounted on the door 200, and a cable is provided between the spring-loaded rotating part 410 and the latch. The limiting part 420 is connected to the spring-loaded rotating part 410 and is used to limit the rotation of the spring-loaded rotating part 410. When the ejection mechanism 500 moves in the first direction, it pushes the spring-loaded rotating part 410 to rotate around the second direction, which can be referred to in [reference needed]. Figure 2 In the direction indicated by arrow b, the spring-loaded rotating part 410 separates the latch from the buckle via a cable; when the ejector mechanism 500 separates from the spring-loaded rotating part 410, the spring-loaded rotating part 410 moves in the opposite direction of the second direction and causes the latch to engage with the buckle.

[0047] In this embodiment, the spring-loaded rotating part 410 may include a reset mechanism, such as a reset spring. When the ejector mechanism 500 moves along the first direction, it can push the spring-loaded rotating part 410 to rotate around the second direction. Since the spring-loaded rotating part 410 is connected to the latch via a cable, it can drive the latch to move during the rotation of the spring-loaded rotating part 410, thereby opening the door 200. The limiting part 420 provided in the spring-loaded rotating part 410 can effectively limit the rotation angle of the spring-loaded rotating part 410 to prevent the spring-loaded rotating part 410 from being difficult to reset due to an excessive rotation angle. When the ejector mechanism 500 separates from the spring-loaded rotating part 410, it can be understood that when the ejector mechanism 500 moves in the opposite direction of the first direction, the ejector mechanism 500 no longer applies force to the spring-loaded rotating part 410. At this time, during the rotation of the spring-loaded rotating part 410 in the opposite direction of the second direction, it again drives the latch to move via the cable.

[0048] To better illustrate the above process, this application provides a feasible implementation method. When it is necessary to open the car door 200, the door controller 700 first controls the ejection mechanism 500 to move along a first direction. During the movement of the ejection mechanism 500 along the first direction, it pushes the spring-loaded rotating part 410 in the unlocking mechanism 400 to rotate around a second direction. The limiting part 420 provided in the spring-loaded rotating part 410 can prevent the spring-loaded rotating part 410 from rotating too much. During the rotation, the spring-loaded rotating part 410 can drive the bolt in the door lock mechanism 300 to move through the cable, thereby separating the bolt from the lock body. At this time, the car door 200 is unlocked. Then, the ejection mechanism 500 continues to move along the first direction and pushes the car door 200 to rotate around the vehicle body 100. When the ejection mechanism 500 reaches its maximum stroke, it remains in its current state, thereby preventing passengers from "pinching their hands" when opening the car door 200. When a passenger rotates the door 200 to a preset threshold angle, the door controller 700 controls the ejection mechanism 500 to rotate in the opposite direction of the first direction. During this movement, the ejection mechanism 500 separates from the spring-loaded rotating part 410 in the unlocking mechanism 400, and the spring-loaded rotating part 410 begins to reset, rotating in the opposite direction of the second direction. During this rotation, the spring-loaded rotating part 410 again controls the movement of the latch via a cable.

[0049] In one embodiment, the ejection mechanism 500 includes an ejector column and a drive element. The drive end of the drive element is connected to the ejector column, and the drive element is capable of controlling the ejector column to reciprocate along a first direction and the opposite direction. The drive element can be a motor.

[0050] In one embodiment, the travel distance of the top column includes a first travel segment and a second travel segment. During the first travel segment, the top column controls the unlocking mechanism 400 to operate, causing the door lock mechanism 300 to open the door 200. During the second travel segment, the top column controls the door 200 to rotate around the vehicle body 100, ensuring that the angle between the door 200 and the vehicle body 100 is within a first threshold range. It should be noted that the first and second travel segments can be adjusted according to actual conditions, and they are two consecutive travel segments. The first threshold range, where the angle between the door 200 and the vehicle body 100 is within this range, means that when a passenger inserts their fingers between the door 200 and the vehicle body 100, their hand will not be pinched.

[0051] In one embodiment, the door controller 700 includes a touch switch disposed on the vehicle body 100. The touch switch can control the ejection mechanism 500 to move along a first direction. In this embodiment, when a passenger needs to board the vehicle, the passenger can control the touch switch to activate the ejection mechanism 500, thereby opening the door 200. By providing a touch switch, passengers can directly control the opening of the door 200.

[0052] In one embodiment, the angle detection module 600 includes a micro switch. The angle detection module 600 can send a signal to the door controller 700 via the micro switch, causing the door controller 700 to control the ejection mechanism 500 to move in the opposite direction of the first direction. When the angle detection module 600 detects that the angle between the door 200 and the vehicle body 100 reaches a preset threshold, the micro switch in the angle detection module 600 can send a signal, thereby causing the ejection mechanism 500 to move in the opposite direction of the first direction. It should be noted that the micro switch has the characteristics of high sensitivity and high reliability. Therefore, when the angle information obtained by the angle detection module 600 reaches the threshold, the signal can be quickly transmitted to the door controller 700 via the micro switch. The door controller 700 can then cause the ejection mechanism 500 to move in the opposite direction of the first direction, that is, the ejection mechanism 500 completes the retraction action, preventing the door 200 from colliding with the ejection mechanism 500 during the rapid closing process.

[0053] This application also proposes a door 200 control method, which can control the aforementioned door system. The door 200 control method includes the following steps:

[0054] S110: The door controller 700 controls the ejection mechanism 500 to move along the first direction. When the ejection mechanism 500 moves along the first direction, it causes the unlocking mechanism 400 to activate. The unlocking mechanism 400 controls the door lock mechanism 300 to unlock the door 200. When the ejection mechanism 500 moves along the first direction, it pushes the door 200 to rotate around the vehicle body 100. After the ejection mechanism 500 moves along the first direction to its maximum stroke, the ejection mechanism 500 maintains its current state.

[0055] S120: The angle between the door 200 and the vehicle body 100 is obtained by the angle detection module 600. When the angle between the door 200 and the vehicle body 100 exceeds the preset first threshold, the door controller 700 controls the ejection mechanism 500 to move in the opposite direction of the first direction through the signal sent by the angle detection module 600.

[0056] The aforementioned door 200 control method first involves the door controller 700 controlling the ejector mechanism 500 to move along a first direction. During this movement, the unlocking mechanism 400 activates, causing the door lock mechanism 300 to unlock the door 200. After continuing to move along the first direction to its maximum travel, the ejector mechanism 500 maintains its current state, thus ensuring a gap between the door 200 and the vehicle body 100 to prevent hand pinching when passengers place their hands between them. When the angle between the door 200 and the vehicle body 100 reaches a preset first threshold, indicating the passenger is inside the vehicle, the risk of hand pinching is eliminated. The door controller 700 then controls the ejector mechanism 500 to move in the opposite direction of the first direction to prevent collision between the door 200 and the ejector mechanism 500 during closing.

[0057] Finally, this application also proposes a vehicle that includes the aforementioned door system. By incorporating this door system into the door 200, the risk of "hands being pinched" during the opening or closing of the door 200 is effectively avoided.

[0058] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0059] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
