Description

Technical Field

[0001] This invention belongs to the field of automotive parts manufacturing technology, specifically relating to an automotive charging compartment door opening and closing device, an opening and closing control method, and an automotive. Background Technology

[0002] In recent years, new energy vehicles have become very popular. New energy vehicles mainly use electricity as their power source and need to be charged when in use. To facilitate charging, a charging port is usually set on the car body at the location corresponding to the charging socket, and a charging port cover is set at the charging port to protect the charging socket.

[0003] Currently, the charging compartment door primarily relies on microswitches to monitor whether it is fully closed. When the microswitch is triggered, it in turn triggers a locking signal, and the locking action completes the closing of the charging compartment door. However, due to manufacturing tolerances, if a foreign object is caught at a small angle during the closing process, the door may not be fully closed, but the microswitch may have already triggered prematurely, attempting to lock, ultimately resulting in a locking failure. Furthermore, the hinge panel is made of plastic; if the closing action continues even when a foreign object is caught at a small angle, the hinge panel may deform and bend, also causing the microswitch to trigger prematurely. Summary of the Invention

[0004] The purpose of this invention is to provide an opening and closing device, opening and closing control method and automobile for a car charging compartment door, which aims to solve the technical problem that the existing charging compartment door will lock prematurely when a foreign object is caught at a small angle.

[0005] To achieve the above objectives, a first aspect of the present invention provides an opening and closing device for an automotive charging compartment door, comprising a housing, a door cover, a door drive assembly, a locking drive mechanism, and a positioning detection assembly; the housing has a charging port for inserting a charging device; the door cover is provided with a pivot and rotatably mounted on the housing via the pivot; the door drive assembly can drive the door cover to rotate, thereby opening or closing the charging port; the locking drive mechanism is disposed on the housing and can drivably lock or unlock the end of the door cover away from the pivot; the positioning detection assembly is non-contact and includes a sensor and a trigger, one of which is disposed at the end of the housing away from the pivot, and the other is disposed at the end of the door cover away from the pivot, and the sensor is communicatively connected to the locking drive mechanism.

[0006] In some embodiments of the present invention, the sensing element is a magnetic sensing element, and the triggering element is a magnet.

[0007] In some embodiments of the present invention, the magnetic induction element is disposed on the housing and connected to the locking drive mechanism wire, and the magnet is disposed on the hatch cover plate.

[0008] In some embodiments of the present invention, the housing includes a concave flat plate portion, a vertical plate portion, and an outer edge plate portion. The concave flat plate portion is provided with a charging port. The vertical plate portion is arranged to surround and extend outward along the edge of the concave flat plate portion to form a cover space. The outer edge plate portion extends outward from the edge of the vertical plate portion away from the concave flat plate portion towards the side opposite to the cover space. The hatch cover plate is provided with a sealing ring that can be placed in the cover space and abuts against the vertical plate portion. A magnetic induction element is provided on the inner side of the outer edge plate portion, and a magnet is provided on the outer side of the hatch cover plate and is located at a position corresponding to the sealing ring.

[0009] In some embodiments of the present invention, the hatch cover plate has a locking hole formed within the sealing ring, and the locking drive mechanism includes a locking rod body and a locking rod drive assembly. The locking rod body is movably disposed on the inner side of the concave plate portion, and the end of the locking rod body away from the pivot passes through the concave plate portion and forms a locking head. The locking rod drive assembly can drive the locking rod body to move so as to drive the locking head to exit or insert into the locking hole.

[0010] In some embodiments of the present invention, the locking hole is centrally located at the end of the hatch cover away from the pivot, and the concave flat plate is centrally located at the end away from the pivot with a push-pull mounting opening. The locking rod body includes a first rod segment, a second rod segment, and a locking head. The first rod segment is located on one side of the charging port and can be pushed and pulled. The second rod segment is connected to the first rod segment and is located on the side of the charging port away from the pivot. The locking head is located at the end of the second rod segment away from the first rod segment and extends out from the push-pull mounting opening. The locking rod drive assembly is drivenly connected to the end of the first rod segment away from the second rod segment to drive the locking head to move in the push-pull mounting opening in the direction of exiting or inserting into the locking hole.

[0011] In some embodiments of the present invention, the magnetic sensing element is a Hall switch.

[0012] To achieve the above objectives, a second aspect of the present invention provides a method for controlling the opening and closing of an automotive charging compartment door, wherein the method is applied to an automotive charging compartment door opening and closing device according to the above description, and includes:

[0013] If the hatch door drive assembly malfunctions and closes the hatch cover without triggering the sensor, control the hatch door drive assembly to open the hatch cover in the reverse direction.

One of the sensor and the trigger is located at the end of the housing away from the pivot, and the other is located at the end of the door cover away from the pivot. Compared with the prior art, this invention replaces the mechanical microswitch with a non-contact positioning detection component. The positioning detection component has no manufacturing tolerances and can be calibrated online before shipment. Furthermore, the installation position is moved from the side close to the pivot to the side away from the pivot. The side away from the pivot is the locking end of the door cover. The positioning detection component is designed to detect whether the locking end is closed properly. Compared with the prior art where the microswitch is located close to the pivot, the positioning detection component in this invention is moved forward, eliminating the amplification effect of the movement path and improving the accuracy of positioning detection. This ensures that when the charging compartment door is caught with a foreign object at a small angle and is not fully closed, the sensor will not be triggered, thus avoiding premature locking.

[0039] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0040] In view of the above-mentioned defects caused by using a micro switch to detect the closed position in the background technology, the inventors of this application have conducted a lot of research and found that the main reasons are: (1) the micro switch is a mechanical switch and there are tolerances in the manufacturing process; (2) the micro switch is located at the near end of the rotating shaft and far from the locking end of the charging compartment door, which has an amplified effect on the detection of the closed position, thus affecting the detection accuracy.

[0041] Based on the above findings, this invention proposes a positioning detection component located at the far end of the rotating shaft. The positioning detection component is non-contact, has no manufacturing tolerances, and can be calibrated online before shipment, thereby solving the technical problems mentioned in the background art.

[0042] The following description, with reference to the accompanying drawings, describes the automobile charging compartment door opening and closing device, opening and closing control method, and automobile according to the present invention.

[0043] like Figures 1 to 4 As shown, the present invention provides an opening and closing device for an automotive charging compartment door, wherein the automotive charging compartment door opening and closing device includes:

[0044] The housing 100 has a charging port 111 for inserting a charging device;

[0045] The hatch cover 200 is provided with a pivot 210 and is rotatably mounted on the housing 100 through the pivot 210;

[0046] The hatch drive assembly 300 can drive the hatch cover 200 to rotate, thereby opening or closing the charging port 111.

[0047] A locking drive mechanism 400 is provided on the housing 100 and can drive the locking or unlocking of the end of the hatch cover 200 away from the rotating shaft 210.

[0048] The positioning detection component is non-contact and includes a sensor and a trigger. One of the sensor and the trigger is located at the end of the housing 100 away from the rotating shaft 210, and the other is located at the end of the hatch cover 200 away from the rotating shaft 210. The sensor is communicatively connected to the locking drive mechanism 400.

[0049] When using the aforementioned car charging compartment door opening and closing device, since the positioning detection component is made non-contact and includes a sensor and a trigger, with one of the sensor and trigger located at the end of the housing 100 away from the rotating shaft 210 and the other located at the end of the door cover 200 away from the rotating shaft 210, compared to the prior art, this invention replaces the mechanical microswitch with a non-contact positioning detection component. The positioning detection component has no manufacturing tolerances and can be calibrated online before shipment. Furthermore, the installation position is changed from being close to the rotating shaft 210... One side is moved to the side away from the pivot 210. The side away from the pivot 210 is the locking end of the door cover 200. The purpose of the positioning detection component is to detect whether the locking end is closed. Compared with the prior art where the micro switch is placed near the pivot 210, the positioning detection component in this invention is moved forward, and there is no amplification effect of the movement path, which improves the accuracy of positioning detection. As a result, when the charging door is caught with a foreign object at a small angle and is not closed completely, the sensor will not be triggered, thus avoiding the phenomenon of premature locking.

[0050] Specifically, the sensor can be triggered when the trigger is in a certain set position. Even if the hatch cover 200 clamps a foreign object at a small angle in this set position, the locking drive mechanism 400 can still successfully lock. However, if the trigger is not in this set position, the sensor cannot be triggered. Furthermore, the communication connection mentioned in this invention can be a wired connection or a wireless connection.

[0051] In some embodiments of the present invention, the sensing element is a magnetic sensing element 500, and the triggering element is a magnet 600. Choosing magnetic sensing makes the setting of the triggering element simpler and more convenient. Of course, the present invention is not limited to this; light sensing, etc., can also be chosen. However, light-sensing triggering elements require power-on settings, which would make manufacturing more complex.

[0052] In some embodiments of the present invention, the magnetic induction element 500 is disposed on the housing 100 and wiredly connected to the locking drive mechanism 400, and the magnet 600 is disposed on the hatch cover plate 200. By choosing to dispose of the magnetic induction element 500 on the fixedly installed housing 100, it is easier to realize the wiring for the wired connection to the locking drive mechanism 400, and avoid wiring on the hatch cover plate 200.

[0053] In some embodiments of the present invention, the magnetic induction element 500 is disposed on the inner side of the housing 100, which makes the housing 100 more aesthetically pleasing. Meanwhile, the magnet 600 is disposed on the outer side of the hatch cover 200, which prevents it from adversely affecting the sealing of the hatch cover 200. It should be noted that the definition of inward and outward directions in the present invention is based on the inward and outward directions of a vehicle.

[0054] Please see again Figures 1 to 4 In some embodiments of the present invention, the housing 100 includes a concave flat plate portion 110, a vertical plate portion 120, and an outer edge plate portion 130. The concave flat plate portion 110 is provided with a charging port 111. The vertical plate portion 120 is arranged to surround and extend outward along the edge of the concave flat plate portion 110 to form a cover space. The outer edge plate portion 130 extends outward from the edge of the vertical plate portion 120 away from the concave flat plate portion 110 towards the side opposite to the cover space. The hatch cover plate 200 is provided with a sealing ring 220 that can be placed in the cover space and abuts against the vertical plate portion 120. The magnetic induction element 500 is provided on the inner side of the outer edge plate portion 130, and the magnet 600 is provided on the outer side of the hatch cover plate 200 and is located at a position outside the sealing ring 220. When the hatch cover 200 is closed, the sealing ring 220 is placed in the cover space to ensure a reliable seal. At the same time, the part of the hatch cover 200 outside the sealing ring 220 is positioned opposite to the outer edge plate 130. By placing the magnetic induction element 500 on the outer edge plate 130 and the magnet 600 on the part of the hatch cover 200 outside the sealing ring 220, the magnetic induction element 500 and the magnet 600 can be placed closer together, thereby further improving the detection accuracy.

[0055] In some embodiments of the present invention, the hatch cover 200 has a locking hole 231 formed within the sealing ring 220. The locking drive mechanism 400 includes a locking rod body 410 and a locking rod drive assembly 420. The locking rod body 410 is movably disposed inside the concave flat plate portion 110, and one end of the locking rod body 410 away from the pivot 210 passes through the concave flat plate portion 110 and forms a locking head 413. The locking rod drive assembly 420 can drive the locking rod body 410 to move, thereby causing the locking head 413 to exit or insert into the locking hole 231. This allows the main body of the locking rod body 410 and the locking rod drive assembly 420 to be hidden inside the housing 100, which can both ensure aesthetics and provide protection. In addition, arranging the locking rod body 410 on the concave flat plate portion 110, which has a large installation space, makes assembly more convenient.

[0056] Specifically, the inner side of the hatch cover plate 200 is provided with a frame portion 230 that surrounds and forms a locking hole 231 within the sealing ring 220. The frame portion 230 has three frame segments connected in sequence, and the frame segment of the frame portion 230 that is away from the hatch cover plate 200 is designated as the first frame segment. The first frame segment can be hooked by the locking head 413 when it is inserted into the locking hole 231. When the hatch cover plate 200 is closed, the locking head 413 can hook the first frame segment.

[0057] In some embodiments of the present invention, the locking hole 231 is centrally located at the end of the hatch cover plate 200 away from the rotating shaft 210, and a push-pull mounting opening is centrally located at the end of the concave flat plate portion 110 away from the rotating shaft 210. That is, when the hatch cover plate 200 is closed in place, the locking hole 231 and the push-pull mounting opening are directly opposite each other. Figure 3 and Figure 4As shown, the locking rod body 410 includes a first rod segment 411, a second rod segment 412, and a locking head 413. The first rod segment 411 is located on one side of the charging port 111 and can be pushed and pulled. Specifically, the concave flat plate portion 110 has at least two latching portions 112 spaced apart on one side of the charging port 111. The first rod segment 411 passes through the at least two latching portions 112. The second rod segment 412 is connected to the first rod segment 411 and is located on the side of the charging port 111 away from the rotating shaft 210. The locking head 413 is located at the end of the second rod segment 412 away from the first rod segment 411 and extends out from the push-pull mounting port. The locking rod drive assembly 420 is driven to the end of the first rod segment 411 away from the second rod segment 412, so as to drive the locking head 413 to move in the push-pull mounting port in the direction of exiting or inserting into the locking hole 231. By arranging the locking lever 410 in this way, the charging port 111 is centered, and the locking lever 410 can also lock the hatch cover 200 in a centered position, ensuring the reliability of the locking. Simultaneously, setting the pushing and pulling movement of the locking lever 410 in the direction from the hinged end of the hatch cover 200 towards the locking end facilitates the layout design of the locking lever drive assembly 420. Specifically, applying a pushing force to the locking lever 410 by the locking lever drive assembly 420 can push the locking head 413 towards the direction of exiting the locking hole 231, and applying a pulling force to the locking lever 410 by the locking lever drive assembly 420 can pull the locking head 413 towards the direction of inserting into the locking hole 231.

[0058] Specifically, the end of the first rod segment 411 furthest from the second rod segment 412, i.e., the end of the first rod segment 411 closest to the rotating shaft 210, is provided with a rack body. The locking rod drive assembly 420 includes a first rotary drive member 421 and a drive gear. The first rotary drive member 421 is disposed on the housing 100, and the drive gear is disposed on the output shaft of the first rotary drive member 421 and meshes with the rack body. The locking rod drive assembly 420 and the hatch drive assembly 300 can be disposed at opposite ends of the rotating shaft 210. More specifically, the hatch drive assembly 300 includes a second rotary drive member 310, a drive gear 320, and a driven gear 330. The second rotary drive member 310 is disposed on the housing 100, the drive gear 320 is disposed on the output shaft of the second rotary drive member 310, and the driven gear 330 is disposed on the rotating shaft 210 and meshes with the drive gear 320. Both the first rotary drive 421 and the second rotary drive 310 can be power output components with built-in motors and control chips, so as to realize automatic control of hatch opening and closing and locking / unlocking of the locking lever.

[0059] In some embodiments of the present invention, the magnetic sensing element 500 is a Hall switch. A Hall switch is a proximity switch that relies on a chip to sense the strength of a magnetic field. It is calibrable and has the advantages of reliability, long lifespan, fast response speed, and high accuracy. Of course, the present invention is not limited to this; the magnetic sensing element 500 can also be other suitable magnetic sensing elements such as a reed switch.

[0060] Specifically, the unlocking and opening process of the hatch cover 200 is as follows: the vehicle system sends an unlocking command to the first rotary drive member 421 of the lock lever drive assembly 420. After the first rotary drive member 421 drives the locking head 413 to exit the locking hole 231, it sends an opening command to the second rotary drive member 310 of the hatch drive assembly 300. The second rotary drive member 310 drives the hatch cover 200 to rotate and open. After the hatch cover 200 is opened, the sensor will change from the triggered state to the disconnected state. This signal is transmitted to the vehicle system screen to display that the hatch cover 200 is open.

[0061] The closing and locking process of the hatch cover 200 is as follows: The vehicle system sends a closing command to the second rotary drive 310 of the hatch drive assembly 300. The second rotary drive 310 drives the hatch cover 200 to rotate and close. When the hatch cover 200 is completely closed, the sensor will change from the off state to the triggered state. This signal is transmitted to the first rotary drive 421 of the lock lever drive assembly 420. The first rotary drive 421 drives the locking head 413 to insert into the locking hole 231 and perform the locking action. This signal is also transmitted to the vehicle system screen to display that the hatch cover 200 is closed. When the hatch cover 200 is clamped by a foreign object at a small angle and the sensor cannot be triggered, the lock lever drive assembly 420 will not perform the locking operation.

[0062] Furthermore, the present invention also provides a method for controlling the opening and closing of an automotive charging compartment door, wherein the method is applied to the automotive charging compartment door opening and closing device described above, and includes:

[0063] If the hatch door drive assembly 300 abnormally drives and closes the hatch cover 200 and the sensor is not triggered, control the hatch door drive assembly 300 to open the hatch cover 200 in the reverse direction.

[0064] If the hatch door drive assembly 300 abnormally drives and closes the hatch cover 200 and the sensor is triggered, the hatch door drive assembly 300 is controlled to stop driving and the locking drive mechanism 400 is controlled to perform a locking operation.

[0065] Understandably, when the hatch drive assembly 300 abnormally drives the hatch cover 200 to close, it proves that the hatch cover 200 is clamping a foreign object. Even if the foreign object is small, due to the addition of the non-contact positioning detection assembly, the triggering accuracy of the sensor is high. If the sensor is not triggered, the hatch cover 200 is controlled to open in the reverse direction, thereby achieving small-angle anti-pinch.

[0066] Furthermore, the trigger threshold of the sensor can be preset. When the actual value does not reach the preset trigger threshold, it proves that the current position of the hatch cover 200 cannot achieve successful locking of the locking drive mechanism 400, and the hatch cover 200 is opened in the reverse direction to achieve small-angle anti-pinch. When the actual value reaches the preset trigger threshold, it proves that the current position of the hatch cover 200 can achieve successful locking of the locking drive mechanism 400, and at this time the size of the foreign object clamped and the angle of non-closure should be smaller. Even if the hatch cover 200 clamps the foreign object, due to the inclined guidance of the inner wall of the locking hole 231, it will not affect the successful locking of the locking drive mechanism 400. While controlling successful locking, the hatch cover 200 is controlled to stop moving, thereby avoiding the phenomenon of deformation and bending of the hatch cover 200.

[0067] Furthermore, by monitoring the current of the door drive assembly 300, if abnormal fluctuations occur in the current, it can be determined that the door drive assembly 300 is in abnormal drive mode.

[0068] In some embodiments of the present invention, the vehicle charging compartment door opening and closing control method further includes:

[0069] The trigger threshold of the sensor is calibrated online.

[0070] Specifically, the trigger threshold of the sensor can be calibrated online before each vehicle is shipped, thereby avoiding the influence of fluctuations in the manufacturing process. As a result, the sensors of different vehicles have different trigger thresholds, ensuring that successful locking can be achieved when the actual value reaches the trigger threshold.

[0071] The small-angle anti-pinch design principle in the opening and closing device and control method of the car charging compartment door is as follows:

[0072] The positioning detection component uses a Hall switch and a magnet, and the trigger threshold of the Hall switch corresponds to an open angle of 1.5°.

[0073] When the hatch cover is closed to within 3 degrees or more, if a foreign object is caught in it, the calibrated distance between the Hall switch and the magnet will not trigger the Hall switch. In this case, the locking operation will not be performed, and the hatch cover will open in the reverse direction. It should be noted that when the hatch cover is closed to within 3 degrees, if the locking head performs the locking operation, the locking head is located outside the locking hole and is at the critical position of abutting against the frame portion forming the locking hole.

[0074] When the hatch cover is closed to within 2°–3° (excluding 3°), if a foreign object is caught at this point, the calibrated distance between the Hall switch and the magnet will not trigger the Hall switch. In this case, the locking operation will not be performed, and the hatch cover will open in the reverse direction. It should be noted that when the hatch cover is closed to within 2°–3°, if the locking head performs the locking operation, the locking head will be located outside the locking hole and in contact with the frame portion forming the locking hole.

[0075] If a foreign object is caught when the hatch cover is closed to within 1.5° or less of its final angle, the calibrated distance between the Hall switch and the magnet will trigger the Hall switch, initiating the locking operation and stopping the hatch cover. It should be noted that while the locking head can successfully insert into the locking hole when the hatch cover is closed to within 1.5° to 2° (excluding 2°), to account for the tolerances of the calibrated Hall switch, the locking operation will only be initiated when the hatch cover is closed to within 1.5° or less of its final angle.
