Description

Technical Field

[0001] This application relates to the field of automotive technology, and more particularly to the field of automotive door technology, specifically to an unlocking / locking device, a door, a vehicle, and a control method for the unlocking / locking device. Background Technology

[0002] A car door handle is a lever installed on the car door, typically used to open and close the door. Its function is to allow passengers and the driver to easily enter and exit the vehicle. Exposed door handles create a protrusion on the car's surface, significantly impacting the door's design and aesthetics. Furthermore, during vehicle operation, the recessed area created by exposed door handles on the car's surface generates considerable wind resistance. Therefore, concealed door handles are needed to reduce wind resistance generated by the door handles during driving.

[0003] In related technologies, car door handles commonly come in two main concealed designs: one is a parallel outward extension type, and the other is an outward rotation type. Both of these concealed designs achieve their concealed installation by retracting to a state flush with the vehicle body when the vehicle is in motion or the door is closed. However, the concealed door handles in these technologies are not only complicated to operate, but also prone to malfunction in unexpected situations (such as falling into water or freezing in winter), making it impossible for drivers and passengers to open the door normally. Summary of the Invention

[0004] This application provides an unlocking / locking device, a vehicle door, a vehicle, and a control method for the unlocking / locking device, to at least solve the technical problems of complex operation and difficulty in opening concealed door handles in the event of accidents in related technologies. The technical solution of this application is as follows:

[0005] According to a first aspect of this application, an unlocking device is provided, which includes a mounting housing, a cover plate, a handle, a power component, and an actuator.

[0006] The mounting housing forms a mounting cavity and a first opening connecting the mounting cavity to the outside. A cover plate is rotatably connected to the mounting housing and is used to open or close the first opening. A handle is located inside the mounting cavity and is rotatably connected to the mounting housing. The handle is used to open the door lock and includes an abutment part.

[0007] The power component is connected to the mounting housing and is used to connect to the lock cylinder of the door lock. The actuator is connected to the mounting housing; turning the handle causes the abutment part to abut against the actuator, so that the actuator controls the power component to move the lock cylinder to open the door lock.

[0008] According to the above-mentioned technical means, the handle in this application is set inside the mounting cavity, and the cover plate covers the first opening. On the one hand, the handle is installed in a concealed manner. On the other hand, when the vehicle is in motion, the cover plate covers the first opening, and the handle will not protrude from the mounting shell, thus avoiding wind resistance caused by the handle protruding during vehicle operation.

[0009] By turning the handle and applying force, the driver or passenger can rotate the handle's abutment to a position where it contacts the actuator. After the actuator contacts the abutment, the driver or passenger can continue to turn the handle, and the abutment will apply force to the actuator, causing the actuator to move the door lock cylinder, thus unlocking the door. In this way, the driver or passenger can open the door with a simple operation.

[0010] In addition, the unlocking and locking device provided in this application can completely hide the handle inside the car door through a simple mechanical structure. The handle is set in the mounting cavity, and the mounting housing protects the abutting part and actuator of the handle. The rotation path of the handle is not affected by the external environment. When the vehicle faces unexpected situations (such as cold weather such as heavy snow), the driver and passengers can still open the car door normally by using the handle.

[0011] In one possible implementation, when the cover closes the first opening, the surface of the cover away from the mounting cavity is flush with the first surface of the mounting housing, and the first panel opens the first opening; and / or, when the cover opens the first opening, the cover is located inside the mounting cavity.

[0012] According to the above-mentioned technical means, the cover plate in this application can be opened towards the mounting cavity or away from the mounting cavity. When the cover plate closes the first opening, it can completely cover the first opening, so that the mounting cavity is completely isolated from the external environment, thus protecting the structure of the unlocking and locking device.

[0013] Meanwhile, when the cover closes the first opening, the surface of the cover is flush with the surface of the mounting housing, which can avoid wind resistance at the cover during vehicle operation. In addition, the cover opens towards the mounting cavity, making it easy for the driver and passengers to operate.

[0014] In one possible implementation, the power component includes a cable, one end of which is connected to the mounting housing, the other end of which is connected to the lock cylinder, and the other end of which is slidably connected to the mounting housing.

[0015] The actuator includes a slider that is slidably connected to the mounting housing along a first direction perpendicular to the extension direction of the cable. Rotating the handle causes the abutment portion to push the slider to move, thereby causing the slider to slide the other end of the cable.

[0016] According to the above-mentioned technical means, when the abutting part of the handle in this application abuts against the slider, the driver or passenger continues to push the handle, and the abutting part pushes the slider to slide, so that the slider can abut against the cable and cause the cable to deform. When the cable deforms, it can generate a pulling force on the door lock cylinder connected to it, thereby causing the door lock cylinder to disengage from the lock body, thereby switching the car door to the unlocked state.

[0017] In one possible implementation, the unlocking and locking device of this application further includes a first spring member, one end of which is connected to the slider and the other end of which is connected to the mounting housing. During the sliding of the slider, the first spring member deforms.

[0018] According to the above-mentioned technical means, when the driver or passenger rotates the handle, the abutment part pushes the slider to slide. At this time, the first spring member undergoes elastic deformation and will generate a pulling force on the slider. When the driver or passenger releases the handle, the handle no longer applies force to the slider. At this time, the slider slides to the initial position under the pulling force of the first spring member.

[0019] In one possible implementation, the slider in this application forms a mounting groove on the side near the cable, and the actuator also includes a pulley, which is disposed in the mounting groove and is rotatably connected to the slider, and the cable contacts the pulley.

[0020] Based on the above technical means, this application reduces the friction between the cable and the slider by setting a pulley, so that the slider can drive the cable to move more smoothly, avoid the friction between the cable and the slider from causing damage to the cable or the slider, and increase the reliability of the locking device movement.

[0021] In one possible implementation, the actuator in this application further includes a limiting block connected to the slider. The limiting block is located on the side of the pulley away from the bottom wall of the mounting groove, and the cable passes through the gap between the limiting block and the pulley.

[0022] Based on the above technical means, the gap between the limiting block and the pulley in this application can limit the cable. At the same time, the limiting block can prevent the cable from disengaging from the pulley during movement, further improving the reliability of the locking device.

[0023] In one possible implementation, the actuator in this application includes a first sensor and a controller, connected to the mounting housing. When the abutting part abuts against the first sensor, it can trigger the first sensor to acquire first sensing information. The first sensor is electrically connected to the controller, which is configured to:

[0024] Upon receiving the first sensor information, the system controls the power component to move the lock cylinder to open the door lock.

[0025] According to the above-mentioned technical means, in this application, the driver and passenger can also turn the handle to make the contact part come into contact with the first sensing element, the first sensing element transmits the signal to the controller, and the controller controls the power component to realize the automatic opening of the door.

[0026] In one possible implementation, the unlocking and locking device of this application further includes a first drive assembly and a controller. The first drive assembly is connected to the mounting housing and the cover plate, and the first drive assembly is used to drive the cover plate to rotate.

[0027] The controller is electrically connected to the first drive component, and the controller is configured as follows:

[0028] Once the unlocking information is obtained, the first drive component is controlled to rotate the cover plate to open the first opening.

[0029] After the first opening has been open for a first preset time, the first drive component is controlled to drive the cover plate to rotate, thereby closing the first opening.

[0030] Based on the aforementioned technical means, in this application, the driver and passengers can also open the cover electrically to expose the handle from the first opening, further improving the vehicle's intelligence level.

[0031] In one possible implementation, the unlocking / locking device of this application further includes a second sensor connected to the mounting housing. When the cover plate opens the first opening, the second sensor is triggered to acquire second sensing information. The second sensor is electrically connected to a controller, which is further configured to:

[0032] Upon receiving the second sensing information, the first drive component is controlled to stop the cover plate from rotating and to remain in place for a second preset duration.

[0033] According to the above-mentioned technical means, the second sensing element in this application can obtain the opening range and opening time of the cover, allowing time for the driver and passengers to turn the handle to open the car door, so as to make the operation convenient for the driver and passengers, while avoiding injury to the driver and passengers' hands when the cover returns to its position. Moreover, the driver and passengers only need to turn the handle during the whole process, which is simple to operate and improves the performance of the car.

[0034] In one possible implementation, the unlocking and locking device of this application further includes a second spring member, which is disposed in the mounting cavity. One end of the second spring member is connected to the mounting housing, and the other end of the second spring member is connected to the cover plate. When the cover plate opens the first opening, the second spring member undergoes elastic deformation.

[0035] The controller is also configured to: after the cover plate stops rotating and the cover plate remains for a second preset time, the controller controls the first drive component to be de-energized, and the cover plate closes the first opening under the elastic force of the second return spring.

[0036] Based on the above-mentioned technical means, this application sets a second spring-loaded component so that when the car door is closed, the first drive component no longer applies force to the cover plate, and the cover plate can return to its initial position under the action of the second spring-loaded component. The automatic spring-loaded cover plate is achieved through a simple mechanical structure, which eliminates the need for the first drive component to drive the cover plate. This not only saves energy but also ensures that the cover plate can close the first opening even if the first drive component is accidentally de-energized.

[0037] In one possible implementation, the bottom wall of the mounting housing forms a drain port that connects the mounting cavity to the outside.

[0038] Based on the above-mentioned technical means, the sewage and other debris in the installation cavity can be discharged in a timely manner through the water outlet in the installation cavity, thereby further protecting the locking device.

[0039] According to a second aspect provided in this application, a vehicle door is provided, including a door body and the aforementioned unlocking and locking device, the unlocking and locking device being connected to the door body.

[0040] Based on the above-mentioned technical means, the car door in this application, by using the above-mentioned unlocking and locking device, not only reduces the complexity of opening the car door for the driver and passengers, but also simplifies the opening process of the car door. Furthermore, by hiding the handle inside the mounting cavity and preventing it from contacting the external environment, the handle can be prevented from malfunctioning in case of an accident.

[0041] In one possible implementation, the wall surface where the first opening is located is flush with the door surface.

[0042] Based on the aforementioned technical means, in this application, the housing is embedded in the vehicle body of the door, and the first opening is flush with the surface of the door, which can improve the aesthetics of the vehicle and reduce the difficulty for drivers and passengers to open the door.

[0043] In one possible implementation, the mounting housing in this application forms a mounting opening, which includes a first portion and a second portion, the first portion forming a first opening. The vehicle door in this application includes an outer door panel and a seal, the mounting opening is flush with the outer door panel, and the outer door panel blocks the second portion. The seal surrounds the mounting opening and is disposed between the mounting housing and the outer door panel, and the seal abuts against each of the mounting housing and the outer door panel.

[0044] Based on the aforementioned technical means, this application, by setting a sealing element, can further prevent external contaminants from entering the installation cavity, thereby providing further protection for the unlocking and locking device and increasing its reliability.

[0045] According to a third aspect provided in this application, a vehicle is provided, including the aforementioned door.

[0046] Based on the aforementioned technical means, the vehicle in this application has low wind resistance during driving. At the same time, the door locking and unlocking device can be completely hidden. On the one hand, this improves the vehicle's aesthetics, and on the other hand, the locking and unlocking device does not come into contact with the outside world, thus improving the vehicle's reliability.

[0047] According to the fourth aspect provided in this application, a control method for an unlocking device is provided, applied to the aforementioned unlocking device, the control method comprising:

[0048] If the unlocking information is obtained, the first drive component is controlled to drive the cover plate to rotate, so as to open the first opening;

[0049] After the first opening has been open for a first preset time, the first drive component is controlled to drive the cover plate to rotate, thereby closing the first opening.

[0050] Based on the aforementioned technical means, this application can further realize the intelligent opening of the car door, improving the user experience for drivers and passengers.

[0051] Therefore, the above-mentioned technical features of this application have the following beneficial effects:

[0052] (1) The locking and unlocking device of this application has a simple structure, is easy for drivers and passengers to operate, and has low production cost.

[0053] (2) This application achieves the concealed installation of the handle, which is isolated from the external environment, so as to avoid the handle being unable to rotate in case of an accident, thus preventing the car door from being opened normally.

[0054] (3) This application provides a control method for unlocking and locking devices, which further improves the user experience of drivers and passengers.

[0055] It should be noted that the technical effects of any of the implementation methods in the second and fourth aspects can be found in the technical effects of the corresponding implementation methods in the first aspect, and will not be repeated here.

Detailed Implementation

[0073] There are two main types of concealed door handle designs: one is the parallel outward extension type, and the other is the outward rotation type. However, the operation of door handles in this technology is complicated, and there is a risk that they cannot be opened in an emergency.

[0074] To address the aforementioned technical problems, this application provides an unlocking / locking device, comprising a mounting housing 1, a cover plate 2, a handle 3, a power component 4, and an actuator 5.

[0075] The mounting housing 1 forms a mounting cavity 101 and a first opening 1021 connecting the mounting cavity 101 to the outside. The cover plate 2 is rotatably connected to the mounting housing 1 and is used to open or close the first opening 1021. The handle 3 is located inside the mounting cavity 101 and is rotatably connected to the mounting housing 1. The handle 3 is used to open the door lock and includes an abutment part 301.

[0076] The power component 4 is connected to the mounting housing 1 and is used to connect to the lock cylinder of the door lock. The actuator 5 is connected to the mounting housing 1. Rotating the handle 3 causes the abutment part 301 to abut against the actuator 5, so that the actuator 5 controls the power component 4 to move the lock cylinder to open the door lock.

[0077] Based on this, see Figure 1 The handle 3 is located inside the mounting cavity 101. When the vehicle is in motion or when the driver or passengers do not need to turn the handle 3, the cover plate 2 closes the first opening 1021. Thus, the mounting housing 1 can hide the handle 3, achieving a completely hidden installation of the handle 3.

[0078] Furthermore, when the cover plate 2 covers the first opening 1021, the cover plate 2 and the mounting housing 1 can isolate the handle 3 from the outside world. When encountering freezing weather such as rain or snow, the structure of the handle 3 can be unaffected by the external environment and will not affect the driver and passengers from opening the car door normally.

[0079] Specifically, see Figure 1 and combined Figure 2When the driver or passenger needs to open the car door, they rotate the cover plate 2, insert their hand into the mounting cavity 101, and rotate the handle 3. During the rotation, the abutment part 301 of the handle 3 abuts against the actuator 5. As the handle 3 is rotated, the abutment part 301 of the handle 3 pushes the actuator 5 to move. One end of the actuator 5 is connected to the power component 4. When the actuator 5 moves, it can drive the power component 4 to move, thereby switching the lock cylinder of the door lock to the unlocked state.

[0080] As can be seen from the above description, the locking / unlocking device in this application has a simple structure, is easy for drivers and passengers to operate, and further improves the user experience.

[0081] In some embodiments, see Figure 1 and combined Figure 2 When the cover plate 2 closes the first opening 1021, the surface of the cover plate 2 away from the mounting cavity 101 is flush with the first surface 102 of the mounting housing 1.

[0082] Based on this, see Figure 3 When the cover plate 2 closes the first opening 1021, the surface of the cover plate 2 away from the mounting cavity 101 is flush with the first surface 102 of the mounting housing 1. The entire surface of the mounting housing 1 has no protrusions. During the vehicle's operation, the surface of the mounting housing 1 in contact with the outside world is a plane. In this way, the surface of the mounting housing 1 will not generate large wind resistance during the vehicle's operation, which improves the vehicle's stability. At the same time, it can reduce the air resistance encountered by the vehicle during operation, reduce fuel consumption, and improve fuel economy.

[0083] In some embodiments, when the cover plate 2 opens the first opening 1021, the cover plate 2 is located inside the mounting cavity 101.

[0084] Based on this, see Figure 4 and combined Figure 5 When the driver or passenger needs to open the car door, they can rotate the cover plate 2, which can be completely located inside the mounting cavity 101. On the one hand, by adjusting the direction of the first opening 1021 of the cover plate 2 so that it faces the inside of the mounting cavity 101, the aesthetics of the car are improved. On the other hand, the cover plate 2 will not obstruct the driver's or passenger's hand when opening the car door. The driver or passenger can open and fix the cover plate 2 with one hand, and can also pull the handle 3 with the same hand when fixing the cover plate 2, which improves the driver's or passenger's experience.

[0085] In some embodiments, see Figure 1 and combined Figure 7 The power component 4 includes a cable 401, one end of which is connected to the mounting housing, the other end of which is connected to the lock cylinder, and the other end of which is slidably connected to the mounting housing 1.

[0086] The actuator 5 includes a slider 501, which is slidably connected to the mounting housing 1 along a first direction perpendicular to the extension direction of the cable 401. Rotating the handle 3 can cause the abutment part 301 to push the slider 501 to move, so that the slider 501 drives the other end of the cable 401 to slide.

[0087] Based on this, when the driver or passenger pulls the handle 3, the abutment part 301 abuts against the slider 501. As the handle 3 continues to rotate, the abutment part 301 generates a pushing force on the slider 501, which in turn causes the cable 401 to change position. At this time, the cable 401 will generate an unlocking force on the end of the lock cylinder connected to it. Under the action of the cable 401, the lock cylinder can switch to the unlocked state, so that the driver or passenger can open the car door normally.

[0088] Specifically, see Figure 8 and combined Figure 1 The surface of the mounting housing 1 is provided with a slide rail 105, and one side surface of the slider 501 is provided with a second slide groove 507. The second slide groove 507 is slidably connected to the slide rail 105 so that the slider 501 can slide on the surface of the mounting housing 1.

[0089] Based on this, through the cooperation of the slide groove 507 and the slide rail 105, the slider 501 can maintain a stable sliding trajectory on the surface of the mounting housing 1, avoiding swaying or deviation, thus improving the motion stability of the slider 501. At the same time, the slide groove 507 also plays a certain guiding role for the slide rail 105, further enhancing the reliability of the cooperation between the slider 501 and the mounting housing 1.

[0090] Further, see Figure 9 and combined Figure 2 The surface of the mounting housing 1 is provided with a positioning block 104, and the cable 401 passes through the positioning block 104 and is slidably connected to the positioning block 104.

[0091] In this way, the positioning block 104 not only supports the cable 401, but also guides the movement of the cable 401, further enhancing the reliability and stability of the unlocking and locking device in this application.

[0092] In some embodiments, see Figure 1 The unlocking and locking device in this application also includes a first spring-loaded member 7. One end of the first spring-loaded member 7 is connected to the slider 501, and the other end of the first spring-loaded member 7 is connected to the mounting housing 1. During the sliding of the slider 501, the first spring-loaded member 7 deforms.

[0093] Based on this, as the driver pushes the slider 501 to slide by the handle 3, the slider 501 exerts a force on the first return spring 7, causing the first return spring 7 to deform. After the driver releases the handle 3, the first return spring 7 exerts a spring force on the slider 501, allowing the slider 501 to return to its initial position. The driver does not need to manually return the parts to their original positions, thus improving the efficiency of the locking device.

[0094] For example, the first rebound element 7 can be a torsion spring, rubber, or an elastic cord. This application does not limit this.

[0095] In addition, the maintenance cost of the first spring component 7 is low, which reduces the production cost of automobiles.

[0096] In some embodiments, the slider 501 in this application forms a mounting groove 505 on the side near the cable 401, and the actuator 5 also includes a pulley 502, which is disposed in the mounting groove 505 and is rotatably connected to the slider 501, and the cable 401 contacts the pulley 502.

[0097] Based on this, by setting up a slider 501, the friction between the slider 501 and the cable 401 can be reduced, the resistance to the movement of the cable 401 can be reduced, and the movement of the cable 401 can be made easier and smoother, so that the driver and passengers can easily open the car door. At the same time, the pulley 502 can also reduce the wear of the cable 401 during the transmission process and extend the service life of the cable 401.

[0098] Further reading continues Figure 9 In this application, a first groove 506 is formed on the surface of the slider 501, and the cable 401 is disposed in the first groove 506 and slidably connected to the first groove 506. In this way, under the guiding action of the first groove 506, the accuracy of the installation position of the cable 401 and the accuracy and stability of the movement trajectory during the sliding process are ensured.

[0099] In other embodiments, to further reduce wear on the cable 401, lubricating oil can be applied to the surface of the pulley 502 to make the cable 401 move more smoothly.

[0100] In some embodiments, see continue to see Figure 9 The actuator 5 also includes a limiting block 503, which is connected to the slider 501. The limiting block 503 is located on the side of the pulley 502 away from the bottom wall of the mounting groove 505. The cable 401 passes through the gap 504 between the limiting block 503 and the pulley 502.

[0101] Based on this, by setting the limit block 503, not only can the cable 401 be prevented from separating from the slider 501, but the stability of the connection between the cable 401 and the slider 501 can also be further guaranteed, thereby further improving the reliability of the locking device.

[0102] In some embodiments, see Figure 10 The actuator 5 includes a first sensor 6, which is connected to the mounting housing 1. When the abutting part 301 abuts against the first sensor 6, it can trigger the first sensor 6 so that the first sensor 6 can acquire first sensing information.

[0103] The unlocking and locking device also includes a controller, and the first sensor 6 is electrically connected to the controller, which is configured to:

[0104] Upon receiving the first sensor information, the power component 4 is controlled to move the lock cylinder to open the door lock.

[0105] For example, the first sensing element 6 is a sensor switch.

[0106] Based on this, when the driver or passenger opens the car door, they can also turn the handle to make the handle come into contact with the first sensor 6, thereby transmitting the first sensing information to the controller. After receiving the first sensing information, the controller controls the power component 4 connected to the lock cylinder to work, and the power component 4 switches the lock cylinder to the unlocked state.

[0107] For example, the power component 4 is an electric motor. When the electric motor starts working, it moves the lever or linkage of the lock cylinder through mechanical transmission, thereby opening the car door lock.

[0108] Understandably, the first sensor information is the information indicating that the door lock has been opened.

[0109] In some embodiments, the unlocking and locking device in this application further includes a first driving component and a controller. The first driving component is connected to the mounting housing 1 and the cover plate 2, and the first driving component is used to drive the cover plate 2 to rotate.

[0110] The controller is electrically connected to the first drive component, and the controller is configured as follows:

[0111] If the unlocking information is obtained, the first drive component is controlled to drive the cover plate 2 to rotate, so as to open the first opening 1021.

[0112] After the first opening 1021 has been open for a first preset time, the first drive assembly is controlled to drive the cover plate 2 to rotate, so as to close the first opening 1021.

[0113] It should be noted that the first preset duration is the total time from when the driver or passenger moves to the front of the car door and pulls the handle to open the door until the driver or passenger's hand is removed from the mounting cavity 101. This first preset duration can be set by the driver or passenger. For example, the first preset duration is 30 seconds.

[0114] For example, the cover plate 2 is rotated at an angle of 72° so that the driver or passenger can reach into the mounting cavity 101 to rotate the handle 3.

[0115] For example, the car sensor can sense the distance between the car door key carried by the driver and the car. The car sensor transmits the information to the controller, and the unlocking information is that the distance between the car door key and the car is less than or equal to a preset distance. In addition, the unlocking information can also be the unlocking information remotely issued by the driver or passenger using the car door key, and this application does not limit it.

[0116] Specifically, the first drive component includes a motor, the output end of which is connected to a rotating shaft. The cover plate 2 is fitted onto the rotating shaft. When the motor is powered on, it can drive the rotating shaft to rotate, thereby causing the rotating shaft to drive the cover plate 2 to rotate and open the first opening 1021.

[0117] Furthermore, when the motor is powered off, the shaft is in an automatic state, and the driver and passengers can push the cover 2 to open the first opening 1021. In this way, even if the car experiences an unexpected power outage, the driver and passengers can still successfully open the car door.

[0118] Furthermore, in case of unexpected situations, such as heavy snow or cold weather, if the opening is frozen and the cover 2 is difficult to open, even if the driver and passengers need to break the cover 2 to open the door, it will not affect the operation of the internal handle 3. This ensures that even in extreme weather conditions, the driver and passengers can open the door normally through the hidden door handle 3.

[0119] In addition, even if the cover plate 2 is damaged, its repair cost is low, which can save drivers and passengers the expenses incurred during vehicle repair and further improve the user experience.

[0120] In some embodiments, a second spring member 8 is also included. The second spring member 8 is disposed in the mounting cavity 101. One end of the second spring member 8 is connected to the mounting housing 1, and the other end of the second spring member 8 is connected to the cover plate 2. When the cover plate 2 opens the first opening 1021, the second spring member 8 undergoes elastic deformation.

[0121] For example, the second rebound element 8 in this application can be a torsion spring, rubber, or an elastic rope. This application does not limit the application in this regard.

[0122] The controller is also configured to: after the cover plate 2 stops rotating and the cover plate 2 remains for a second preset time, the controller controls the first drive component to be de-energized, and the cover plate 2 closes the first opening 1021 under the elastic force of the second return spring 8.

[0123] Based on this, after acquiring the unlocking information, the controller controls the first drive component to be powered on, so as to rotate and open the first opening 1021. After the cover plate 2 is opened for a first preset time, the controller drives the first drive component to be powered off, or the controller drives the output voltage of the first drive component to be reduced, so as to reduce the torque applied to the cover plate 2. The cover plate 2 can return to the initial position under the action of the second spring member 8, so that the handle 3 is completely hidden in the mounting cavity 101.

[0124] In some embodiments, this application further includes a second sensor connected to the mounting housing 1. When the cover 2 opens the first opening 1021, the second sensor is triggered to acquire second sensing information. The second sensor is electrically connected to a controller, which is further configured to:

[0125] Upon receiving the second sensing information, the first drive component is controlled to stop the cover plate 2 from rotating and to remain on the cover plate 2 for a second preset duration.

[0126] It should be noted that the second sensing information is the cover plate 2 rotating to its maximum angle.

[0127] Based on this, see Figure 3 and Figure 4 In order to avoid the cover plate 2 from colliding with the mounting housing 1 due to excessive rotation, a second sensor is provided in the mounting cavity 101 in this application. After the second sensor detects that the cover plate 2 has rotated to the maximum angle, the first drive component controls the cover plate 2 to stop rotating and stays at the maximum angle position for a second preset time to provide time for the driver and passengers to open the car door.

[0128] For example, see Figure 6 The second sensing element is a sensor switch 13. When the cover plate 2 is rotated to the maximum angle and when the cover plate 2 is rotated to the initial position, it can contact the second sensing element so that the controller can obtain the position of the cover plate 2.

[0129] It should be noted that the second preset duration can be set by the driver or passenger. For example, the second preset duration is 0.8 seconds.

[0130] Furthermore, when the cover plate 2 rotates to its maximum angle position, it abuts against the first inductive switch, and when the cover plate 2 rotates to its initial position, it abuts against the second inductive switch.

[0131] Further, see Figure 6This application also includes a limiting rod 9 and a locking block 10. One end of the limiting rod 9 is rotatably connected to the mounting housing 1, and the other end of the limiting rod 9 is connected to the cover plate 2. When the cover plate 2 rotates, it can drive the limiting rod 9 to rotate. The locking block 10 is connected to the mounting housing 1, and when the cover plate 2 closes the first opening 1021, the limiting rod 9 and the locking block 10 are engaged to prevent the cover plate 2 from rotating outside the mounting cavity 101 under the action of the second spring member 8, thereby causing the cover plate 2 to protrude from the surface of the mounting housing 1, which not only affects the overall aesthetics, but also causes the cover plate 2 to generate wind resistance during vehicle operation.

[0132] In some embodiments, the bottom wall of the mounting housing 1 forms a drain outlet 103 that connects the mounting cavity 101 with the outside.

[0133] Based on this, even if water enters the mounting cavity 101, the mounting housing 1 can still drain the water through the drain outlet 103.

[0134] In some embodiments, this application also provides a vehicle door, which includes a door body and the aforementioned unlocking and locking device, the unlocking and locking device being connected to the door body.

[0135] Based on this, drivers and passengers can open the car door normally using the simple unlocking and locking device described in this application. The operation is simple, and the entire unlocking and locking device is located inside the door, which improves the aesthetics of the car door.

[0136] In some embodiments, the wall surface where the first opening 1021 is located is flush with the door surface.

[0137] Based on this, during the vehicle's operation, the cover plate 2 closes the first opening 1021 to make the door surface flat, thereby reducing the wind resistance generated during the vehicle's operation.

[0138] In some embodiments, the mounting housing 1 forms a mounting opening, which includes a first portion and a second portion, the first portion forming a first opening 1021. The vehicle door in this application includes an outer door panel 11 and a seal 12, the mounting opening is flush with the outer door panel 11, and the outer door panel 11 blocks the second portion.

[0139] See Figure 1 and combined Figure 11 The sealing element 12 is disposed around the mounting opening and between the mounting housing 1 and the outer door panel 11, and the sealing element 12 abuts against each of the mounting housing 1 and the outer door panel 11. The sealing element 12 can further protect the mounting cavity 101 so that no foreign matter can enter the mounting cavity 101.

[0140] Based on this, the wall of the mounting cavity 101 near the outside can be surrounded by the sheet metal of the door body, and the first opening 1021 is set on the sheet metal of the door body, which reduces the thickness of the door along the width direction of the vehicle and further improves the integration of the internal structure of the door body.

[0141] In some embodiments, this application also provides a vehicle including the aforementioned door.

[0142] Based on this, during vehicle operation, the vehicle in this application will not generate wind resistance at the door locking / unlocking device, further improving the vehicle's stability during operation and enhancing its aesthetics. As a result, the user experience of the vehicle in this application is further improved.

[0143] In some embodiments, see Figure 12 This application also provides a control method for an unlocking / locking device, applied to the aforementioned unlocking / locking device, comprising:

[0144] S001, The controller obtains the unlocking information and controls the first drive component to drive the cover plate 2 to rotate, so as to open the first opening 1021.

[0145] S002, The controller receives the first sensing information and controls the power component 4 to move the lock cylinder to open the door lock.

[0146] S003. After the first opening 1021 has been open for a first preset time, the controller controls the first drive component to drive the cover plate 2 to rotate, so as to close the first opening 1021.

[0147] Step S002 further includes: the controller receiving the second sensing information, the controller controlling the first drive component to control the cover plate 2 to stop rotating, and the controller controlling the cover plate 2 to remain for a second preset time.

[0148] Step S003 further includes: after the cover plate 2 stops rotating and after the cover plate 2 stays for a second preset time, the controller controls the first drive component to be de-energized, and the cover plate 2 closes the first opening 1021 under the elastic force of the first return member 7.

[0149] Based on this, this application automates the opening of the unlocking device cover 2, improving the vehicle's intelligence level. When opening the door, the driver and passengers only need to pull the handle to open the door without having to operate the cover 2, further enhancing the driver and passengers' experience.

[0150] In some embodiments, the controller in this application can directly power the cover 2 so that the process of opening the cover 2 can be faster, thereby improving the user experience of the driver and passengers.

[0151] Specifically, see Figure 13 and Figure 14 , Figure 13 This is one of the schematic diagrams illustrating the operation of a controller driving the cover 2 to open according to an exemplary embodiment. Figure 14 This is the second schematic diagram illustrating the operation of the controller driving the cover 2 to open according to an exemplary embodiment. Figure 13 and Figure 14 In this context, V represents the controller's output voltage, and t represents the controller's operating time. Figure 13 In this context, V1 represents the peak voltage at which the controller drives the cover plate 2 to open, and T1 represents the time during which the controller controls the cover plate 2 to rotate. Figure 14 V2 in the figure represents the peak voltage at which the controller keeps cover 2 open, and T2 represents the time during which the controller keeps cover 2 open.

[0152] It should be noted that the value of V1 is greater than V2 because when the controller opens the cover plate 2, the force applied by the controller to the cover plate 2 needs to be greater than the force applied to the cover plate 2 by the second spring-loaded component 8. When the controller needs to hold the cover plate 2 in a certain position, the force applied by the controller to the cover plate 2 needs to be equal to the force applied to the cover plate 2 by the second spring-loaded component 8. When the cover plate 2 needs to return to the initial position, the controller interrupts the torsional force output to the cover plate 2, and the cover plate 2 returns to the initial position under the action of the second spring-loaded component 8.

[0153] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
