Description

Technical Field

[0001] This application relates to the field of door lock technology, and in particular to a latch structure, control method, device and terminal equipment. Background Technology

[0002] In various industrial equipment, smart home devices, and transportation equipment, noise, vibration, and harshness (NVH) performance has become one of the key indicators for measuring operational quality and user experience. Taking vehicles as an example, with the continuous development of vehicle technology and the increasing demands of consumers for driving and riding quality, vehicle NVH performance has become an important standard for measuring the overall comfort and premium level of a vehicle.

[0003] As an important component of the vehicle's side structure, the vehicle door locking system (hereinafter referred to as door lock) not only performs the functions of locking and unlocking the doors, but also plays a crucial role in the overall vehicle acoustic sealing system. A typical door lock usually consists of a lock body installed on the door and a latch fixed to the vehicle body. During the closing process, the lock body and the latch engage to achieve mechanical locking; at the same time, the sealing strips set on the door or body are compressed and deformed under the pressure of the door and body, thereby forming an acoustic and environmental seal in the door seam area.

[0004] However, existing door lock systems are unable to meet users' diverse needs for NVH performance. Summary of the Invention

[0005] This application provides a locking structure, control method, device, and terminal equipment to better meet users' different needs for NVH performance.

[0006] Firstly, a control method is provided, which is applied to a terminal device. This method can be executed by the terminal device, or by a module (such as a controller, processor, chip, or chip system) applied in the terminal device, or by a logic node, logic module, or software that can realize all or part of the functions of the terminal device.

[0007] The method may include: determining that the door lock of the terminal device is in a locked state; and, if the device state of the terminal device meets a first condition, adjusting the door lock from a first locking degree to a second locking degree to enhance the sealing effect of the door of the terminal device; wherein the second locking degree is greater than the first locking degree.

[0008] This solution allows for precise control of the fit between the door and the equipment body, as well as the door gap, by dynamically adjusting the lock's tightness. This enables adjustment of the door's sealing effect and flexibly responds to users' varying NVH performance needs in different scenarios. Furthermore, by actively increasing the lock's tightness, the overall sealing effect and NVH performance of the equipment can be effectively enhanced in high-noise, high-airflow-turbulence, or high-humidity environments. This significantly reduces the impact of external interference (such as changes in airflow pressure, rain / water flow impact, etc.) on the equipment's sealing performance, thereby improving the overall environmental adaptability and reliability of the equipment. At the same time, this mechanism also provides users with a quieter and more intelligent user experience.

[0009] Furthermore, this solution introduces a trigger mechanism based on equipment status, triggering locking adjustment only when the equipment status meets a first condition. This effectively identifies operating conditions with high requirements for sealing and NVH performance, avoiding unnecessary locking adjustments to some extent. This helps extend the service life of related components and improves the accuracy and rationality of locking adjustment. In addition, before performing dynamic locking adjustment, this solution first ensures the door lock is in the locked state. This better prevents ineffective and erroneous adjustments, reduces unnecessary control energy consumption, and improves the overall energy efficiency of the control logic.

[0010] In one possible implementation of the first aspect, the method further includes: adjusting the door lock from a second locking degree to a first locking degree when the device state meets the second condition.

[0011] In the above embodiments, by determining whether the equipment status meets the second condition, it is possible to effectively identify working conditions with low requirements for sealing and NVH performance. Furthermore, by resetting the door lock's tightness to the first tightness when the equipment status meets the second condition, the mechanical load on the door lock system can be reduced in working conditions where high sealing or high NVH performance requirements are not required, thereby helping to extend the service life of related components. At the same time, it can also reduce the rebound force when opening the car door, improving the user experience.

[0012] In one possible implementation of the first aspect, the device state satisfies a first condition indicating that the terminal device is in a high-speed driving state.

[0013] At high speeds, the equipment door is susceptible to outward elastic deformation due to fluctuations in external airflow pressure. This leads to a larger gap between the door and the equipment body, reducing the compression of the sealing strip and weakening the overall sealing performance. In the above embodiment, increasing the locking tightness of the door lock enhances the fit between the door and the equipment body, effectively reducing the impact of door deformation on the gap and the compression of the sealing strip, and significantly improving sealing reliability and NVH performance under high-speed conditions.

[0014] In one possible implementation of the first aspect, the first condition includes: the terminal device's travel speed is higher than the target speed.

[0015] In the above embodiments, when the driving speed of the terminal device is higher than the target speed, the locking tightness of the door lock is increased. This allows for a rapid response to changes in airflow pressure based on the dynamic relationship between the driving speed and the target speed, and timely adjustment of the door lock's locking tightness to ensure NVH performance.

[0016] In one possible implementation of the first aspect, the first condition includes: the duration for which the terminal device's speed is higher than the target speed is greater than the target duration; and if, when the door lock is in the second locking position, the duration for which the terminal device's speed is lower than or equal to the target speed is greater than the target duration, the door lock is adjusted to the first locking position.

[0017] The aforementioned dual discrimination mechanism based on speed and time can effectively suppress frequent switching or false triggering of locking due to fluctuations in driving speed, improve the stability and reliability of the system, and significantly reduce the number of start-stop cycles and mechanical shocks of the drive components, thus extending the service life of related parts.

[0018] In one possible implementation of the first aspect, the second locking degree is positively correlated with the travel speed.

[0019] This implementation allows the door lock's tightening to dynamically match air pressure changes at different driving speeds, more accurately compensating for changes in sealing caused by the elastic deformation of the door body. This helps maintain stable sealing and NVH performance during high-speed driving. Furthermore, matching the door lock's tightening to actual needs effectively reduces energy consumption and mechanical wear of the drive components, improving the energy efficiency and lifespan of the door lock system.

[0020] In one possible implementation of the first aspect, the device state satisfies a first condition indicating that the terminal device is in a rainy scenario.

[0021] In rainy conditions, raindrops impacting the device generate noise, and rainwater accumulating on the door surface may seep into the vehicle through door gaps. Furthermore, the lubricating effect of rainwater may weaken the sealing effect of the weatherstripping. This embodiment automatically increases the door lock's tightness when the device is in rain, enhancing the fit between the door and the device, significantly improving the overall sealing performance, and reducing the risk of rainwater leakage while improving NVH performance.

[0022] In one possible implementation of the first aspect, the first condition includes: the rainfall sensed by the first sensor is greater than the target rainfall.

[0023] In this embodiment, increasing the locking tightness of the door lock when the rainfall reaches a certain level can improve the NVH performance and waterproof sealing level of the equipment while reducing the locking operation in light rain scenarios. This not only helps to extend the service life of the door lock system, but also reduces the occurrence of accidental locking and improves system stability.

[0024] In one possible implementation of the first aspect, the device status satisfies a first condition indicating that the terminal device is in a device cleaning scenario.

[0025] In equipment cleaning scenarios, the equipment body is subjected to high-intensity, high-pressure water jets, especially in areas such as door gaps where instantaneous water pressure concentration can easily occur. This continuous high-pressure water jet not only generates noise but may also cause water to seep into the equipment through the door gaps. In addition, the lubricating effect of some chemical cleaning agents may weaken the sealing effect of the sealing strip. In this embodiment, during equipment cleaning, the locking tightness of the door lock is automatically increased. This enhances the fit between the door and the equipment body, significantly improving the overall sealing performance of the equipment. While improving NVH performance, it also reduces the risk of high-pressure water seeping in along the door gaps.

[0026] In one possible implementation of the first aspect, the first condition includes: the switch state of the device cleaning mode is on, or the first sensor data indicates that the terminal device is in the device cleaning state.

[0027] Based on the above implementation method, the system can flexibly determine whether the device is in a cleaning state according to its functional configuration: if the device provides a cleaning mode, the device status can be quickly identified directly based on the on / off status of the cleaning mode; if the device does not provide a cleaning mode, the device status is identified based on sensor data. This allows for better adaptation to different functional configurations and expands the applicability of the solution.

[0028] In one possible implementation of the first aspect, the device status satisfies a first condition indicating that the terminal device is in a low-temperature environment.

[0029] In low-temperature environments, the sealing strip between the door and the equipment body undergoes physical changes such as hardening and reduced compression resilience due to the low temperature, which weakens the sealing performance. In this embodiment, increasing the locking tightness of the door lock in low-temperature environments compensates for the loss of sealing capacity caused by changes in the physical properties of the sealing strip, thereby better ensuring the sealing performance and NVH performance of the equipment's opening and closing system in low-temperature environments.

[0030] In one possible implementation of the first aspect, the first condition includes: the ambient temperature is lower than the target temperature.

[0031] In the above embodiments, when the ambient temperature is lower than the target temperature, the locking tightness of the door lock is increased. This allows for a rapid response to changes in ambient temperature based on the dynamic relationship between the ambient temperature and the target temperature, and timely adjustment of the locking tightness of the door lock to ensure NVH performance.

[0032] In one possible implementation of the first aspect, the device state satisfies a first condition indicating that the terminal device is in a quiet mode, which includes at least one of the following modes: rest mode, audio / video playback mode, and call mode.

[0033] In quiet mode, users have high requirements for NVH performance, such as reducing the noise and vibration of terminal equipment. In this implementation, when the equipment is in quiet mode, the locking tightness of the door lock is automatically increased, which can enhance the fit between the door and the equipment body, effectively improving the overall sealing performance and NVH performance of the equipment.

[0034] In one possible implementation of the first aspect, the first condition includes: the switch state of the quiet mode read from the target controller is in the on state, or the second sensing data satisfies the condition that the terminal device is in quiet mode.

[0035] Based on the above implementation method, the system can flexibly determine whether the device is in silent mode according to its functional configuration: if the device provides a silent mode, the device status can be quickly identified directly based on the on / off state of the silent mode; if the device does not provide a silent mode, the device status is identified based on sensor data. This allows for better adaptation to different functional configurations and expands the applicability of the solution.

[0036] In one possible implementation of the first aspect, the first condition includes: a received operation command for the locking mode instructs the locking mode to be activated.

[0037] Based on this implementation method, users can flexibly adjust the locking tightness of the door lock through the locking mode as needed, thereby achieving flexible adjustment of NVH performance.

[0038] In one possible implementation of the first aspect, the method further includes: adjusting the door lock to a first locking position in response to an opening operation when the door lock is in a second locking position.

[0039] Based on this implementation method, the elastic potential energy accumulated by the sealing strip due to the large amount of compression can be effectively released, significantly reducing the impact and rebound force caused by the excessively fast rebound when the door is opened, thereby reducing abnormal noise during the opening process, making the opening action smoother and quieter, and thus improving the user experience.

[0040] In one possible implementation of the first aspect, the door lock has a cooperating lock body and a latch, the position of which is adjustable, and the locking tightness of the door lock is determined by adjusting the position of the latch.

[0041] The structure of the latch is relatively simple and easier to integrate with an adjustable design. In the above implementation, the locking adjustment function is integrated into the latch side, which can reduce system complexity and cost.

[0042] Secondly, a latch structure is provided, including: a mounting base and a latch, the latch being slidably connected to the mounting base, and the latch corresponding to different locking degrees in different sliding positions; under the first locking degree, the door lock corresponding to the latch is in a locked state; when the device state of the terminal device to which the latch is installed meets the first condition, the latch is in a second locking degree, the second locking degree being greater than the first locking degree.

[0043] In this solution, the latch position is adjustable, allowing for dynamic adjustment of the lock's tightness. This enables the regulation of the seal between the door and the equipment, flexibly responding to users' varying NVH performance needs in different scenarios. Furthermore, by actively increasing the tightness when the equipment meets certain conditions, the overall sealing and NVH performance can be effectively enhanced in high-noise, high-airflow-turbulence, or high-humidity environments. This significantly reduces the impact of external interference (such as changes in airflow pressure, rain / water flow impact, etc.) on the equipment's sealing performance, thereby improving the overall environmental adaptability and reliability of the equipment. It also provides users with a quieter and more intelligent user experience.

[0044] In one possible implementation of the second aspect, the latch structure further includes: a slider and a drive assembly; the latch is slidably connected to the mounting base along a first direction; the slider is slidably disposed within the latch, the slider having a push surface for contacting the latch, the push surface being inclined relative to the first direction; the drive assembly is connected to the slider for driving the slider to slide along a second direction; when the slider slides along the second direction, the push surface can push the latch to slide along the first direction, the second direction being different from the first direction.

[0045] In this embodiment, by controlling the sliding stroke and position of the latch through the drive component, the latch position can be automatically adjusted, improving the adaptability and intelligence of the latch structure. Furthermore, by setting a slider that slides through the latch, with the slider's pushing surface inclined relative to the first direction, when the drive component drives the slider along the second direction (e.g., vertically or obliquely), the displacement in the second direction can be efficiently converted into sliding of the latch along the first direction through the inclined surface of the pushing surface. This inclined surface transmission mechanism achieves motion reversal without complex linkage mechanisms, resulting in a simple structure that helps reduce the overall structural complexity and cost of the device, and also reduces the overall size, thus facilitating integration into space-constrained terminal devices.

[0046] In one possible implementation of the second aspect, the second direction is perpendicular to the first direction.

[0047] Based on the above implementation method, the linear displacement relationship between the slider and the latch can be easily achieved by designing the inclination of the push surface, thereby facilitating precise control of the latch stroke; in addition, it can prevent the latch from pushing the slider in the opposite direction, improving the stability of the latch position; and it can also shorten the slider stroke and improve the response speed.

[0048] In one possible implementation of the second aspect, the drive assembly includes a drive motor, a meshing gear, and a rack; the gear is connected to the drive motor, and one end of the rack is connected to a slider; the drive motor is used to drive the gear to rotate, thereby causing the rack to move along the second direction.

[0049] In this embodiment, the gear and rack transmission mechanism can efficiently and smoothly convert the rotational motion of the motor into sliding linear motion, which not only improves the accuracy and response speed of sliding control, but also facilitates precise adjustment of the slider position through motor control signals. Furthermore, this structure is compact, easy to integrate into confined installation spaces, and has a strong load capacity and reliable, stable operation.

[0050] In one possible implementation of the second aspect, the drive assembly further includes a meshing worm gear and a worm, the worm being coaxially connected to the drive shaft of the drive motor, and the worm gear being coaxially connected to a gear.

[0051] In this embodiment, the worm gear transmission mechanism can provide a high transmission ratio and a large output torque, enabling the drive motor to drive the slider to overcome a large resistance and push the latch to slide with a small power output; moreover, due to its inherent self-locking characteristics, it can effectively prevent the latch from sliding under external disturbances, improving the reliability of the locked state; in addition, based on the worm gear structure, the output shaft of the drive motor and the rack can be arranged in parallel, which can save installation space.

[0052] In one possible implementation of the second aspect, the slider and the mounting base are slidably connected along the second direction; the mounting base and the slider are provided with mutually cooperating limiting structures, which limit the slider to slide along the second direction.

[0053] Based on the above implementation method, the stability and reliability of the slider sliding can be improved.

[0054] Thirdly, an opening and closing system is provided, comprising: a door body, a lock body, and a latching structure as described in the second aspect or any embodiment thereof, wherein one of the latching structure and the lock body is mounted on the door body.

[0055] The beneficial effects of the third aspect can be found in the relevant description in the second aspect above, and will not be repeated here.

[0056] Fourthly, a control device is provided for use in a terminal device. The control device includes a determining module and an adjusting module. The determining module is used to determine that the door lock of the terminal device is in a locked state. The adjusting module is used to adjust the door lock from a first locking degree to a second locking degree to enhance the sealing effect of the door of the terminal device when the device state of the terminal device meets a first condition. The second locking degree is greater than the first locking degree.

[0057] Fifthly, a control device is provided, comprising: a memory and a processor, wherein the memory is used to store a computer program; and the processor is used to execute the method described in the first aspect or any embodiment of the first aspect when the computer program is invoked.

[0058] In a sixth aspect, a terminal device is provided, comprising: a locking structure as described in the second aspect or any embodiment thereof, or an opening and closing system as described in the third aspect, or a control device as described in the fourth or fifth aspect.

[0059] In one possible implementation of the sixth aspect, the terminal device is a vehicle, and the locking structure is located on the vehicle body.

[0060] In a seventh aspect, a program product is provided that, when the program product is run on a device, causes the device to perform the method described in the first aspect or any embodiment of the first aspect.

[0061] Eighthly, a chip system is provided, including a processor coupled to a memory, the processor executing a program stored in the memory to implement the method described in the first aspect or any embodiment thereof. The chip system may be a single chip or a chip module composed of multiple chips.

[0062] In a ninth aspect, a readable storage medium is provided having a program stored thereon that, when executed by a processor, implements the method described in the first aspect or any embodiment of the first aspect.

[0063] It is understood that the beneficial effects of aspects four through nine above can be found in the relevant descriptions in aspect one above, and will not be repeated here. Attached Figure Description

Detailed Implementation

[0065] The embodiments of this application are described below with reference to the accompanying drawings. The terminology used in the implementation section of this application is only for explaining specific embodiments and is not intended to limit the application. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0066] The NVH performance of terminal equipment is a key indicator for measuring its operational quality and user experience. Taking vehicles as an example, NVH performance has become an important standard for measuring overall vehicle comfort and premium level. Currently, vehicle door locks generally adopt a fixed locking design, meaning that the relative position of the lock body and the latch remains constant after the door is closed. However, this design has significant limitations in actual use. For example, during high-speed driving, the door is prone to elastic deformation due to changes in airflow pressure, thus increasing the door gap. The fixed locking design cannot compensate for this change in door gap, resulting in a decrease in the compression of the sealing strip between the door and the body, leading to a decline in sealing performance and consequently, a deterioration in NVH performance. In addition, in some usage scenarios, users expect a quieter in-vehicle environment, but the fixed locking design lacks adaptive adjustment capabilities and cannot further optimize the sealing effect, thus failing to meet users' diverse needs for NVH performance.

[0067] Based on this, embodiments of this application provide a locking structure and adjustment method, which adopts a locking design with adjustable locking position, and can dynamically adjust the position of the locking to adjust the locking degree, so as to better meet the user's needs for NVH performance.

[0068] The technical solutions provided in this application can be applied to vehicles or other terminal devices that require door locks, such as industrial equipment, smart home devices, and transportation equipment. For ease of description, this application mainly uses vehicles as an example for illustrative purposes. Here, "vehicle" is a broad concept and can refer to transportation vehicles (such as commercial vehicles, passenger cars, motorcycles, trains, airplanes, or ships), industrial vehicles (such as forklifts, trailers, and tractors), engineering vehicles (such as excavators, bulldozers, and cranes), agricultural equipment (such as lawnmowers and harvesters), amusement equipment, and toy vehicles. In some optional embodiments, the vehicle can be a pure electric vehicle, a hybrid electric vehicle, a range-extended electric vehicle, or a gasoline-powered vehicle. This application does not specifically limit the type of vehicle.

[0069] To facilitate understanding, the system architecture of the embodiments of this application will be introduced first below.

[0070] Figure 1 The system architecture diagram provided for the embodiments of this application is as follows: Figure 1 As shown, a vehicle door lock system (i.e., a door lock) may include a lock body 01 and a latch 02. One of the lock body 01 and the latch 02 may be installed on the door 001, and the other may be installed on the vehicle body 002. Here, by way of example, the lock body 01 is installed on the door 001, and the latch 02 is fixed to the vehicle body 002. A sealing strip 03 that matches the door 001 may be provided on the door 001 or the vehicle body 002.

[0071] It is understood that door locks can be installed on the left front door, right front door, left rear door, right rear door and trunk door of the vehicle. For ease of explanation, the left front door is used as an example in this embodiment.

[0072] Figure 2 (a) in the diagram shows the door in the open state. Figure 2 (b) in the diagram shows the door in the closed state, as shown below. Figure 2 As shown in (a) and (b), when the car door 001 is in the open state (i.e., the door is open), the latch 02 is separated from the lock body 01; when the car door 001 is closed, the latch 02 can be engaged with the lock body 01, thereby locking the car door in the closed position; when the car door 001 is opened, under the action of the door handle, the latch 02 can disengage from the lock body 01, realizing the unlocking and opening of the car door 001.

[0073] When the door 001 is in the closed state (i.e., the door is closed), the sealing strip 03 is compressed and deformed under the pressure of the door 001 and the body 002, thereby sealing the door gap area and improving the vehicle's NVH performance.

[0074] In this embodiment, the locking tightness of the door lock can be adjusted. When the door lock is in the locked state, the locking tightness of the door lock can be adjusted to achieve different NVH performance.

[0075] Figure 3 The diagram illustrates the locking states of the car door locks at different levels of tightness. Figure 3 In the first locking state shown in (a), the door lock is in the first locking degree; Figure 3 In the second locking state shown in (b), the door lock is at a second locking degree; the second locking degree is greater than the first locking degree. Compared with the first locking state, in the second locking state, the gap between the door 001 and the body 002 is smaller, the compression of the sealing strip 03 is greater, the sealing effect is better, and correspondingly, the NVH performance is better.

[0076] It is understandable that the above explanation is based on the case where the vehicle is not subjected to external forces. When the vehicle is subjected to external forces, such as when the door 001 bulges outward due to airflow pressure, the door gap and the amount of compression of the sealing strip 03 may change.

[0077] Furthermore, it is understood that in some embodiments, a sealing strip may not be provided between the door (e.g., a car door) and the device body (e.g., a vehicle body), and the door or device body may have a certain degree of elasticity; or, even if the door and device body are rigid structures, when the locking tightness of the door lock increases, the gap between the door and the device body will decrease accordingly, and the sealing effect and NVH performance can be improved accordingly. For ease of description, this application embodiment mainly uses the example of a sealing strip provided between the door and the device body for illustration.

[0078] In some embodiments, the position of the latch 02 is adjustable, and the locking tightness of the door lock can be adjusted by adjusting the position of the latch 02.

[0079] Figure 4 This is a schematic diagram of the locking structure provided in the embodiments of this application, such as... Figure 4 As shown, the locking structure may include a mounting base 1 and a locking buckle 2. The locking buckle 2 is slidably connected to the mounting base 1 along a first direction (represented by the y direction in the figure); the locking buckle 2 corresponds to different locking degrees in different sliding positions.

[0080] Figure 5 A cross-sectional view of the mounting base 1 and the latch 2 is shown, as follows: Figure 5 As shown, a groove 11 can be formed on the mounting base 1 along the y-direction, and the latch 2 can slide along the groove 11. In some examples, both ends of the latch 2 can pass through the groove 11, and a limiting structure can be used to prevent the latch 2 from disengaging from the groove 11. For example, both ends of the latch 2 can be fitted with bushings or fixed to the stop plate 12. Figure 5 The example provided uses the stop plate 12 as an example. In other examples, both ends of the latch 2 can also be fixed to the slide plate, with the slide plate slidably connected to the groove 11, and the latch 2 slidably connected to the mounting base 1 via the slide plate. The groove 11 on the mounting base 1 can include one or more grooves, for example... Figure 5 The mounting base 1 shown can have a groove 11, and the two ends of the latch 2 can pass through the groove 11; or two grooves 11 can be formed, and the two ends of the latch 2 can pass through the corresponding grooves 11 respectively. In other examples, the latch 2 can also be slidably connected to the mounting base 1 in other ways, and this embodiment does not particularly limit this.

[0081] Different levels of tightness can be achieved by adjusting the sliding position of the latch 2 in the slide groove 11. Taking the upper end of the latch 2 near the car door as an example, in... Figure 3 In the first locking state shown in (a), the latch 2 can be located at the upper end of the slide groove 11; when adjusted from the first locking state to... Figure 3 In the second locking state shown in (b), the latch 2 can slide downwards to increase the locking tightness.

[0082] In some embodiments, the latch 2 can correspond to two fixed locking degrees. That is, the door lock can switch between a fixed first locking degree and a fixed second locking degree. The first locking degree can be the initial locking degree corresponding to when the door lock switches from the unlocked state to the locked state, and the latch 2 can be located at the uppermost end of the slide groove 11. The latch 2 corresponding to the second locking degree can be located at the lowermost end of the slide groove 11. That is, the latch 2 can be positioned at the uppermost or lowermost end of the slide groove 11 to achieve two-level adjustment.

[0083] In some implementations, the latch 2 can correspond to more than three fixed locking degrees, meaning the door lock can switch between these multiple fixed locking degrees. The latch 2 can be positioned at multiple locations on the slide rail 11 to achieve multi-level adjustment. For example, the latch 2 can be positioned at the uppermost, middle, or lowermost end of the slide rail 11 to achieve three locking degrees, and the first and second locking degrees mentioned above can be any two of these locking degrees.

[0084] In some implementations, the locking tightness corresponding to latch 2 can be steplessly adjusted. It is understood that stepless adjustment is relative to the multi-level adjustment mentioned above, and it has a finer adjustment granularity. Compared with multi-level adjustment, stepless adjustment has a wider range of adjustment, that is, the door lock can be adjusted between more locking tightness levels, and latch 2 can be positioned in more sliding positions.

[0085] In some embodiments, an adjustment mechanism such as a toggle, push-pull, or rotation structure that cooperates with the latch 2 can be provided. The sliding position of the latch 2 can be adjusted by manually operating the adjustment mechanism, thereby adjusting the tightness.

[0086] In some embodiments, such as Figure 4 As shown, the locking structure may also include a slider 3 and a drive assembly 4. The slider 3 is slidably inserted into the locking 2. The slider 3 has a push surface 30 for contacting the locking 2. The push surface 30 is inclined relative to the first direction (i.e., the y direction). The drive assembly 4 is connected to the slider 3 and is used to drive the slider 3 to slide along the second direction. When the slider 3 slides along the second direction, the push surface 30 can push the locking 2 to slide along the y direction.

[0087] The second direction differs from the first direction (i.e., the y-direction). In some examples, the second direction can be parallel to the tilt direction of the push surface 30 to reduce the required driving force. In some examples, the second direction can be perpendicular to the first direction. In this way, the tilt angle of the push surface 30 (e.g., 45 degrees) can be designed to easily achieve a linear displacement relationship between the slider 3 and the latch 2, thereby facilitating precise control of the latch stroke. In addition, it can prevent the latch 2 from pushing the slider 3 in the opposite direction, improving the stability of the latch position; and it can also shorten the slider stroke and improve the response speed. Figure 4The example given is that the second direction can be perpendicular to the first direction. This second direction is the x-direction. For ease of description, this example will be used in the following explanations.

[0088] The upper push surface 30 of the slider 3 is inclined relative to the first direction (i.e., the y-direction), forming an inclined surface. When this inclined surface contacts the latch 2, it generates a driving force along its normal direction. This driving force has a component in the y-direction, which can push the latch 2 to slide along the y-direction. That is, through the inclined design of the push surface 30, the movement of the slider 3 in the second direction is converted into a driving force in the y-direction acting on the latch 2.

[0089] The tilt direction of the upper push surface 30 of slider 3 can be as follows: Figure 4 As shown, the slider 3 is tilted from the upper left to the lower right. When the slider 3 moves to the left, the push surface 30 can push the latch 2 downward; when the slider 3 moves to the right, the latch 2 can slide upward. In other examples, the tilt direction of the push surface 30 on the slider 3 can also be from the lower left to the upper right. When the slider 3 moves to the right, the push surface 30 can push the latch 2 downward; when the slider 3 moves to the left, the latch 2 can slide upward. For ease of description, the following uses... Figure 4 The tilt direction shown is used as an example for explanation.

[0090] In some examples, one side of the slider 3 facing the latch 2 is an inclined push surface 30, for example, Figure 4 The lower end face of the middle slider 3 can form a pushing surface 30. When the slider 3 moves to the left, the pushing surface 30 can push the latch 2 to slide downward. When the slider 3 moves to the right, the latch 2 can slide upward under the counter-pulling action of the door. Alternatively, an elastic element can be provided at the lower end of the latch 2, and the latch 2 can slide upward under the rebound action of the elastic element.

[0091] In other examples, see Figure 4 The two opposing surfaces of the slider 3 facing the latch 2 are both inclined push surfaces 30, and these two push surfaces 30 are parallel. In this way, the latch 2 can be pushed to slide in one direction of the y-direction (e.g., upward) by one push surface 30, and pushed to slide in the other direction of the y-direction (e.g., downward) by the other push surface 30. That is, the latch 2 can be driven bidirectionally by the bidirectional movement of the slider 3, which helps to simplify the overall structure. Moreover, the symmetrical push surfaces 30 on both sides of the slider 3 can make the latch 2 more evenly stressed during the movement, thereby helping to improve the smoothness of the movement.

[0092] In some embodiments, an inclined surface can be provided at the position where the latch 2 contacts the push surface 30 of the slider 3. The inclined surface cooperates with the push surface 30, so that the inclined surface can guide the push surface 30 and guide it to slide smoothly. Moreover, it can make the force transmission between the latch 2 and the slider 3 more uniform, effectively reduce the phenomenon of motion jamming, and thus improve the sliding smoothness of the latch 2.

[0093] In some examples, the inclined surface on the latch 2 can be parallel to the push surface 30 to form a surface contact structure. This can increase the contact area between the latch 2 and the slider 3, making the force distribution between them more uniform. At the same time, it can suppress the possible offset and wobbling phenomenon during the relative sliding of the latch 2 and the slider 3, thereby improving the sliding stability of the latch 2.

[0094] In other examples, the inclined surface on the latch 2 can also form a preset angle with the push surface 30, which can reduce the contact area between the latch 2 and the slider 3, reduce the frictional resistance when the two slide relative to each other, and improve the smoothness of sliding.

[0095] In specific implementation, any of the above implementation methods can be selected as needed, and this embodiment does not impose any particular limitation on this.

[0096] In some embodiments, the slider 3 can be slidably connected to the mounting base 1 along a second direction (i.e., the x-direction). Optionally, the mounting base 1 and the slider 3 can be provided with mutually cooperating limiting structures, which can limit the sliding of the slider 3 along the x-direction to improve the stability and reliability of the slider 3's sliding. For example, one of the mounting base 1 and the slider 3 can have a limiting groove along the x-direction, and the other can have a limiting block that cooperates with the limiting groove. The limiting block can be embedded in the limiting groove and slide along the x-direction within the limiting groove. In other embodiments, the slider 3 can also be mounted on other fixed structures and slidably connected to those fixed structures. This embodiment does not particularly limit the fixing method of the slider 3.

[0097] In some embodiments, the drive assembly 4 may include a drive motor 41, a meshing gear 42, and a rack 43; wherein the gear 42 is connected to the drive motor 41, and one end of the rack 43 is connected to the slider 3; the drive motor 41 is used to drive the gear 42 to rotate, so as to drive the rack 43 to move in the x direction, thereby driving the slider 3 to slide in the x direction.

[0098] In this embodiment, the gear and rack transmission mechanism can efficiently and smoothly convert the rotational motion of the motor into sliding linear motion, which not only improves the accuracy and response speed of sliding control, but also facilitates precise adjustment of the slider position through motor control signals. Furthermore, this structure is compact, easy to integrate into confined installation spaces, and has a strong load capacity and reliable, stable operation.

[0099] In some embodiments, gear 42 can be coaxially connected to the output shaft of drive motor 41, and when drive motor 41 drives output shaft to rotate, it can drive gear 42 to rotate.

[0100] In some embodiments, the drive motor 41 can drive the gear 42 to rotate via a meshing worm gear 44 and worm 45. The worm 45 is coaxially connected to the drive shaft of the drive motor 41, and the worm gear 44 is coaxially connected to the gear 42.

[0101] In this embodiment, the worm gear transmission mechanism can provide a high transmission ratio and a large output torque, so that the drive motor 41 can drive the slider 3 to overcome a large resistance and push the latch 2 to slide with a small power output; moreover, due to its inherent self-locking characteristics, it can effectively prevent the latch 2 from sliding under external disturbances, thus improving the reliability of the locked state; in addition, based on the worm gear structure, the output shaft of the drive motor 41 and the rack 43 can be arranged in parallel, which can save installation space.

[0102] Optionally, the worm gear 45 can be fixedly connected to the end of the output shaft of the drive motor 41. The worm wheel 44 is coaxially and fixedly connected to the gear 42. In some examples, the diameter of the worm wheel 44 can be smaller than the diameter of the gear 42, so that when the worm wheel 44 rotates, the gear 42 can drive the rack 43 to move at a faster speed, thereby achieving faster adjustment of the locking position. In other examples, the diameter of the worm wheel 44 can be larger than the diameter of the gear 42, so that when the worm wheel 44 and the gear 42 rotate at the same angle, the circumferential distance of the gear 42 is smaller, that is, the displacement of the rack 43 is smaller, which helps to achieve fine adjustment of the locking position and improve locking accuracy.

[0103] The aforementioned drive assembly 4 can be fixed to the mounting base 1 or other fixed structure. In other embodiments, the drive motor 41 can also drive the slider 3 to slide through other transmission mechanisms. For example, a lead screw that is threaded into the slider 3 can be used. The drive motor 41 can drive the lead screw to rotate through the drive gear 42 on the output shaft and the driven gear 42 on the lead screw, thereby driving the slider 3 to slide. This embodiment does not particularly limit the specific implementation of the drive assembly 4.

[0104] In some embodiments, the position adjustment of the latch 2 can also be achieved through other structures. For example, a sliding base can be provided on the side of the mounting base 1 away from the latch 2. After the two ends of the latch 2 pass through the mounting base 1, they are fixedly connected to the sliding base. The sliding base can be driven to slide in the first direction by the drive assembly 4, thereby causing the latch 2 to slide in the first direction. Alternatively, the end of the drive assembly 4 can be directly connected to the latch 2. For example, the end of the rack 43 can be connected to both ends or one end of the latch 2. The drive motor 41 can drive the rack 43 to move in the first direction, thereby causing the latch 2 to slide in the first direction.

[0105] In some embodiments, the position of the lock body is adjustable, and the locking tightness of the car door lock can be adjusted by adjusting the position of the lock body. For example, a drive mechanism connected to the lock body can be provided to drive the lock body to move away from the latch 2, thereby increasing the locking tightness of the car door lock; or the drive mechanism can drive the lock body to move closer to the latch 2, thereby decreasing the locking tightness of the car door lock. Alternatively, other methods can be used, such as the lock body engaging with the latch 2 via a pawl, and the pawl being rotated by a drive mechanism to adjust its locking position, thereby adjusting the locking tightness. This application does not specifically limit the implementation method of adjusting the lock body position or the locking tightness. For ease of explanation, the embodiments of this application will be referred to as... Figure 4 The locking structure shown is used as an example for illustration.

[0106] As mentioned above, in the embodiments of this application, the locking tightness of the door lock can be dynamically adjusted in different scenarios. The following describes the control method.

[0107] Figure 6 This is a flowchart illustrating the control method provided in an embodiment of this application. This method can be executed by a terminal device, a module applied within the terminal device (e.g., a controller, processor, chip, or chip system), or a logic node, logic module, or software capable of implementing all or part of the terminal device's functions. Taking a vehicle as an example, the controller can be a vehicle domain controller (VDC), body domain controller (BDC), vehicle integration unit (VIU), or cockpit domain controller (CDC), etc. For ease of description, the following explanation uses the VDC in the vehicle as the executing entity of this method. Figure 6 As shown, the method may include some or all of the following steps: S110. When the door lock of the terminal device is in the locked state and the device state meets the first condition, adjust the door lock from the first locking degree to the second locking degree; the second locking degree is greater than the first locking degree.

[0108] S120. If the equipment status meets the second condition, adjust the door lock from the second locking degree to the first locking degree.

[0109] VDC can detect the locking status of the door lock through sensors built into the lock, such as Hall effect sensors or microswitches, to detect the position of the pawl or other components in the lock body to determine the locking status. This embodiment does not particularly limit the implementation method of detecting the locking status of the door lock.

[0110] In addition to determining the locking state of the door lock, VDC can determine the state of the vehicle (i.e., the device state). Based on the determined device state, it can identify whether the vehicle is in a target scenario where the locking tightness can be increased. When the device state meets the first condition, it can be determined that the vehicle is in the target scenario. At this time, the door lock can be adjusted from the first locking tightness to the second locking tightness.

[0111] When the door lock is in the second locking position, the VDC can identify whether the vehicle has left the target scene based on the determined device status; when the device status meets the second condition, it can be determined that the vehicle has left the target scene, at which point the door lock can be adjusted back to the first locking position.

[0112] In some examples, the device status can be characterized by device status parameters. The VDC can obtain the device status parameters of the vehicle and determine whether the device status meets the corresponding conditions by judging whether the device status parameters meet the first condition or the second condition.

[0113] In some examples, VDC can also use a preset state recognition model to identify device states, or it can directly obtain device states identified by other controllers. When the identified or obtained device state belongs to the device state category corresponding to the target scenario, it can be determined that the device state meets the first condition; when the identified or obtained device state belongs to the device state category not corresponding to the target scenario, it can be determined that the device state meets the second condition.

[0114] For ease of description, the following explanation will primarily use the example of representing device status through device status parameters.

[0115] It should be noted that the process of VDC determining the door lock status and the process of determining whether the device status meets the first condition can be executed sequentially or in parallel. This embodiment does not impose any particular limitation on this.

[0116] As mentioned earlier, in some examples, the door lock can switch between a fixed first locking degree and a fixed second locking degree. The first locking degree can be the initial locking degree when the door lock is engaged, and the second locking degree can be the maximum locking degree corresponding to the latch being at the bottom of the slide. In other examples, the door lock can switch between more locking degrees, and the first and second locking degrees can be any two of the multiple locking degrees. For ease of description, the following explanation will primarily use the first locking degree as the initial locking degree as an example.

[0117] The target scenario can include one or more scenarios, and different scenarios can correspond to different device state parameters, first conditions, and second conditions. VDC can increase the locking degree when any target scenario is identified, and decrease the locking degree after the vehicle leaves the target scenario.

[0118] The following section introduces some possible scenarios.

[0119] High-speed driving scenario VDC can adjust the door locks from the first locking position to the second locking position when the vehicle is traveling at high speed; and adjust the door locks back to the first locking position after the vehicle stops traveling at high speed.

[0120] At high speeds, vehicle doors are susceptible to outward elastic deformation due to fluctuations in external airflow pressure, leading to increased door gaps. This reduces the compression of the sealing strip between the door and the vehicle body, weakening the overall sealing performance. In the above embodiment, increasing the door lock tightness while the vehicle is traveling at high speed enhances the fit between the door and the body, effectively reducing the impact of door deformation on door gaps and sealing strip compression, significantly improving sealing reliability and NVH performance under high-speed conditions. Furthermore, resetting the door lock tightness after the vehicle exits high-speed driving reduces the mechanical load on the door lock system in situations where high sealing requirements are not necessary, thus extending the lifespan of related components. It also reduces the rebound force when opening the door subsequently, improving the user experience.

[0121] VDC can acquire device status parameters (hereinafter referred to as first status parameters) used to identify high-speed driving status. When the first status parameters meet the corresponding first condition, it is determined that the vehicle is in high-speed driving status; when the first status parameters meet the corresponding second condition, it is determined that the vehicle has exited high-speed driving status.

[0122] The first state parameter may include the vehicle speed. In some examples, VDC can obtain the vehicle speed when the vehicle is in drive (i.e., D gear) to save power consumption.

[0123] In some implementations, the first condition may include a driving speed higher than the target speed, and the second condition may include a driving speed lower than or equal to the target speed. That is, VDC can increase the door lock tightness when the vehicle speed is higher than the target speed, and reset the door lock tightness when the vehicle speed is lower than or equal to the target speed. This method can quickly respond to changes in airflow pressure based on driving speed, promptly adjusting the door lock tightness to ensure NVH performance.

[0124] The target speed can be, for example, 60 km / h or 80 km / h, and the specific value can be set according to actual needs. This embodiment does not make any special limitation on this.

[0125] In some implementations, the first condition may include a duration during which the vehicle speed is higher than the target speed for a period longer than the target duration, and the second condition may include a duration during which the vehicle speed is lower than or equal to the target speed for a period longer than the target duration. That is, VDC can increase the locking tightness of the door lock when the vehicle speed is higher than the target speed for a period longer than the target duration, and reset the locking tightness of the door lock when the vehicle speed is lower than or equal to the target speed for a period longer than the target duration.

[0126] The aforementioned dual discrimination mechanism based on speed and time can effectively suppress frequent switching or false triggering of locking due to fluctuations in driving speed, improve the stability and reliability of the system, and significantly reduce the number of start-stop cycles and mechanical shocks of the drive components, thus extending the service life of related parts.

[0127] The target duration can be, for example, 3 seconds (s) or 5 seconds, and the specific duration can be set according to actual needs. This embodiment does not make any special limitation on this.

[0128] In some implementations, the second locking degree is a fixed locking degree. For example, the second locking degree may be a maximum locking degree.

[0129] In some implementations, the second locking degree can be positively correlated with the driving speed. That is, when entering a high-speed driving scenario, a larger locking degree can be used if the driving speed is high, and a smaller locking degree can be used if the driving speed is relatively low. In high-speed driving scenarios, the locking degree of the door lock can be increased accordingly as the driving speed increases, and decreased accordingly as the driving speed decreases. This design allows the door lock locking degree to dynamically match the air pressure changes at different driving speeds, more accurately compensating for changes in sealing caused by the elastic deformation of the door, thereby helping to maintain stable sealing performance and NVH performance during high-speed driving. In addition, matching the door lock locking degree with actual needs can also effectively reduce the energy consumption and mechanical wear of the drive components, improving the energy efficiency and lifespan of the door lock system.

[0130] As mentioned earlier, the door lock can have multiple locking positions, and each locking position corresponds to a driving speed range. When the driving speed is within the driving speed range corresponding to a certain locking position, the door lock can be adjusted to that locking position.

[0131] Rain scene VDC can adjust the door locks from the first locking level to the second locking level when the vehicle is in a rainy situation; and adjust the door locks back to the first locking level after the vehicle leaves the rainy situation.

[0132] In rainy conditions, raindrops impacting the vehicle body generate noise, and rainwater accumulating on the door surfaces can seep into the interior through door gaps. Furthermore, the lubricating effect of rainwater can weaken the sealing effect of the weatherstripping. This implementation automatically increases the door lock tightness when the vehicle is in rain, enhancing the fit between the door and the body, significantly improving the overall sealing performance of the vehicle, improving NVH performance, and reducing the risk of rainwater leakage. After the vehicle leaves the rainy environment, the door lock tightness is reset. This reduces the mechanical load on the door lock system in conditions where high sealing requirements are not necessary, thus helping to extend the service life of related components. It also reduces the rebound force when opening the door subsequently, improving the user experience.

[0133] VDC can acquire device status parameters (hereinafter referred to as second status parameters) used to identify rainy scenarios. When the second status parameters meet the corresponding first condition, it is determined that the vehicle is in a rainy scenario; when the second status parameters meet the corresponding second condition, it is determined that the vehicle has exited the rainy scenario.

[0134] The second state parameter may include rainfall, which can be a rainfall intensity value, rainfall level, or other parameter value that can indicate rainfall. The Vehicle Control Center (VDC) can sense rainfall through relevant sensors (referred to here as the first sensor), which may include, but is not limited to, a rain sensor, a camera, and a piezoelectric sensor. The VDC can determine rainfall based on data detected by one or more sensors. For example, in some examples, the VDC can determine that the vehicle is in a rainy scene if the rainfall detected by the rain sensor reaches a preset threshold; in some examples, the VDC can input the rainfall detected by the rain sensor and the vehicle surface pressure detected by the piezoelectric sensor into a prediction model to determine whether the vehicle is in a rainy scene. This application does not specifically limit the method of identifying rainy scenes.

[0135] In some implementations, the rain scenario can be any rain scenario, such as light rain or heavy rain. That is, VDC can increase the locking tightness of the door lock after detecting rain, and reset the locking tightness of the door lock after the rain stops.

[0136] In some implementations, the rain scenario can specifically be a heavy rain scenario. Correspondingly, the first condition can include rainfall exceeding a target rainfall amount, and the second condition can include rainfall less than or equal to the target rainfall amount. The impact of rainfall intensity on door sealing performance varies significantly. Light rain has a relatively small impact on door sealing performance; however, heavy rain or downpours cause a strong impact on the vehicle body, significantly increasing noise and the risk of water leakage. In this implementation, increasing the door lock tightness when rainfall reaches a certain level can improve vehicle NVH performance and waterproof sealing rating while reducing locking operations in light rain scenarios. This not only helps extend the lifespan of the door lock system but also reduces the possibility of accidental locking triggers, improving system stability.

[0137] The target rainfall can be the rainfall corresponding to scenarios such as moderate rain or heavy rain. The specific amount can be set according to actual needs, and this embodiment does not make any special limitations on it.

[0138] Optionally, to further improve the stability and reliability of the system, similar to the high-speed driving scenario described above, a dual discrimination mechanism based on rainfall and time can be adopted. That is, the first condition may include a duration for which the rainfall is greater than the target rainfall exceeding a first duration, and the second condition may include a duration for which the rainfall is less than or equal to the target rainfall exceeding the first duration. The first duration may be, for example, 1 minute or 3 minutes, and the specific duration can be set according to actual needs; this embodiment does not impose any particular limitation on it.

[0139] In some implementations, the second locking degree can be a fixed locking degree.

[0140] In some implementations, the second locking degree can be positively correlated with the amount of rainfall. That is, when rain is detected, a larger locking degree can be used if the rainfall is heavy, and a smaller locking degree can be used if the rainfall is light. In rainy conditions, the locking degree of the door lock can increase accordingly as the rainfall increases, and decrease accordingly as the rainfall decreases. This design allows the locking degree of the door lock to dynamically match the sealing requirements under different rainfall levels, thereby helping to maintain stable sealing performance and NVH performance in rainy conditions. In addition, matching the locking degree of the door lock to actual needs can also effectively reduce the energy consumption and mechanical wear of the drive components, improving the energy efficiency and lifespan of the door lock system.

[0141] As mentioned earlier, the door lock can have multiple locking positions, and each locking position corresponds to a rainfall range. When the rainfall is within the rainfall range corresponding to a certain locking position, the door lock can be adjusted to that locking position.

[0142] Car wash scene VDC can adjust the door locks from the first locking position to the second locking position when the vehicle is in a car wash scenario; and adjust the door locks back to the first locking position after the vehicle leaves the car wash scenario.

[0143] In a car wash scenario, the vehicle body is subjected to high-intensity, high-pressure water jets, especially in areas like door gaps where instantaneous water pressure concentration can occur. This continuous high-pressure water jet not only generates noise but can also cause water to seep into the vehicle through door gaps. Furthermore, the lubricating effect of some chemical cleaning agents can weaken the sealing effect of the weatherstripping. This implementation automatically increases the door lock tightness while the vehicle is in a car wash scenario. This enhances the fit between the door and the vehicle body, significantly improving the overall sealing performance of the vehicle. This improves NVH performance while reducing the risk of high-pressure water seepage through door gaps. After the vehicle leaves the car wash scenario, the door lock tightness is reset. This reduces the mechanical load on the door lock system in situations where high sealing requirements are not required, thus helping to extend the service life of related components. It also reduces the rebound force when opening the door subsequently, improving the user experience.

[0144] VDC can acquire device status parameters (hereinafter referred to as third status parameters) used to identify car wash scenarios. When the third status parameter meets the corresponding first condition, it is determined that the vehicle is in a car wash scenario; when the third status parameter meets the corresponding second condition, it is determined that the vehicle has exited the car wash scenario.

[0145] In some implementations, when the vehicle provides a car wash mode switch function, the VDC can identify the car wash scenario based on the on / off state of the car wash mode (i.e., the equipment cleaning mode). That is, the third state parameter may include the on / off state of the car wash mode, the first condition may include the on / off state of the car wash mode being in the on state, and the second condition may include the on / off state of the car wash mode being in the off state.

[0146] In some implementations, the VDC can detect in real time whether the vehicle is in a car wash state based on sensor data (referred to here as first sensor data). That is, the third state parameter may include the first sensor data, the first condition may include the first sensor data indicating that the vehicle is in a car wash state (i.e., the equipment is being cleaned), and the second condition may include the first sensor data indicating that the vehicle is in a non-car wash state.

[0147] The first sensing data may include, but is not limited to, rainfall data detected by a rain sensor, radar data detected by ultrasonic radar, visual data detected by a camera, position data collected by a position sensor, and motion state data detected by sensors such as an inertial measurement unit (IMU). The VDC can combine multiple sensing data to identify whether a vehicle is in a car wash state, thereby improving the accuracy of the identification results. For example, a vehicle can be determined to be in a car wash state if the following conditions are met: rainfall data indicates a large amount of water; radar data detects a nearby reciprocating object; visual data identifies the car wash machine / water gun; position data indicates the vehicle is located at a car wash; and motion state data indicates the vehicle is stationary or moving at a slow, uniform speed. This application does not specifically limit the method of identifying the car wash state.

[0148] Optionally, the second locking degree can be a preset locking degree, such as the maximum locking degree. The specific size of the second locking degree is not specifically limited here.

[0149] Low temperature scenarios VDC can adjust the door locks from the first locking level to the second locking level when the vehicle is in a low-temperature environment; and adjust the door locks back to the first locking level when the vehicle leaves the low-temperature environment.

[0150] In low-temperature environments, sealing strips undergo physical changes such as hardening and reduced compression resilience due to the low temperature, which weakens sealing performance. This implementation increases the door lock tightness when the vehicle is in a low-temperature environment. This compensates for the loss of sealing ability caused by changes in the physical properties of the sealing strip, thus better ensuring the sealing and NVH performance of the door system in low-temperature conditions. When the vehicle leaves the low-temperature environment, the door lock tightness is reset. This allows the door lock to be reset promptly after the sealing strip returns to a soft state, reducing the mechanical load on the door lock system in conditions where high sealing requirements are not required. This helps extend the service life of related components and also reduces the rebound force when opening the door, improving the user experience.

[0151] VDC can acquire device status parameters (hereinafter referred to as the fourth status parameters) used to identify low-temperature scenarios. When the fourth status parameters meet the corresponding first condition, it is determined that the vehicle is in a low-temperature scenario; when the fourth status parameters meet the corresponding second condition, it is determined that the vehicle has exited the low-temperature scenario.

[0152] The fourth state parameter may include ambient temperature, which can be detected by a temperature sensor.

[0153] In some implementations, the first condition may include an ambient temperature lower than the target temperature, and the second condition may include an ambient temperature higher than or equal to the target temperature.

[0154] The target temperature can be 5°, 0°, or -5°, etc., and the specific value can be set according to actual needs. This embodiment does not impose any special limitations on this.

[0155] Optionally, to further improve the stability and reliability of the system, similar to the high-speed driving scenario described above, a dual discrimination mechanism of temperature and time can also be adopted. That is, the first condition may include the duration for which the ambient temperature is lower than the target temperature being greater than a second duration, and the second condition may include the duration for which the ambient temperature is higher than or equal to the target temperature being greater than the second duration. The second duration may be, for example, 5 minutes or 10 minutes, etc., and the specific duration can be set according to actual needs. This embodiment does not impose any particular limitation on this.

[0156] In some implementations, the second locking degree can be a fixed locking degree.

[0157] In some implementations, the second locking degree can be negatively correlated with the ambient temperature; that is, a larger locking degree can be used when the ambient temperature is low, and a smaller locking degree can be used when the ambient temperature is relatively high. Optionally, each locking degree setting can correspond to a temperature range, and when the ambient temperature is within the temperature range corresponding to a certain locking degree setting, the door lock can be adjusted to that locking degree setting.

[0158] In some embodiments, the VDC can control the door lock tightness in conjunction with the vehicle's driving status. Optionally, the VDC can increase the door lock tightness when the vehicle is in a low-temperature environment and in motion; and reset the door lock tightness when the vehicle leaves the low-temperature environment or is in motion (i.e., is stationary). This can more accurately meet the vehicle's sealing performance requirements and improve system reliability.

[0159] Tranquil scene VDC can adjust the door locks from the first locking position to the second locking position when the vehicle is in Quiet Mode; and adjust the door locks back to the first locking position after the vehicle exits Quiet Mode.

[0160] In Quiet Mode, users have higher requirements for NVH performance. In this implementation, when the vehicle is in Quiet Mode, the door lock tightness is automatically increased. This enhances the fit between the door and the vehicle body, effectively improving overall sealing and NVH performance. After the vehicle exits Quiet Mode, the door lock tightness is reset. This reduces the mechanical load on the door lock system in conditions where high NVH performance requirements are not necessary, thus helping to extend the lifespan of related components. It also reduces the rebound force when opening the door subsequently, improving the user experience.

[0161] Quiet mode may include, but is not limited to: rest mode, audio / video playback mode, and call mode.

[0162] VDC can acquire device status parameters (hereinafter referred to as the fifth status parameter) used to identify the quiet mode. When the fifth status parameter meets the corresponding first condition, it is determined that the vehicle is in quiet mode; when the fifth status parameter meets the corresponding second condition, it is determined that the vehicle has exited quiet mode.

[0163] In some implementations, the VDC can obtain the on / off state of the quiet mode from a target controller (e.g., a cockpit domain controller) to determine whether the vehicle is in quiet mode. That is, the fifth state parameter may include the on / off state of the quiet mode obtained from the target controller, the first condition may include the quiet mode being in an on state, and the second condition may include the quiet mode being in a off state.

[0164] In some implementations, VDC can detect in real time whether the vehicle is in quiet mode based on sensor data (referred to herein as second sensor data). That is, the third state parameter may include the second sensor data, with a first condition that the second sensor data satisfies the condition that the vehicle is in quiet mode, and a second condition that the second sensor data satisfies the condition that the vehicle is in non-quiet mode.

[0165] For example, the Vehicle Control Center (VDC) can determine that the vehicle is in rest mode when seat sensor data indicates that the seat position is semi-reclined or fully reclined, or when image data captured by the camera indicates that the user has entered a rest state. The VDC can determine that the vehicle is in audio / video playback mode when speaker output data is an audio / video signal or touch sensor data indicates that a playback option has been triggered. The VDC can determine that the vehicle is in call mode when the microphone is in pickup mode, the speaker is switched to hands-free mode, touch sensor data indicates that an answer option has been triggered, or image data captured by the camera indicates that the user is in a call state. It is understood that this is merely an illustrative explanation of the recognition methods for each quiet mode, and this embodiment does not impose any particular limitations on them.

[0166] Optionally, the second locking degree can be a preset locking degree, such as the maximum locking degree. The specific size of the second locking degree is not specifically limited here.

[0167] User adjustment scenario The vehicle can provide a locking mode switch function. When the locking mode is on, the VDC can adjust the door lock from the first locking degree to the second locking degree; when the locking mode is off, it can adjust the door lock back to the first locking degree.

[0168] In this implementation, users can flexibly adjust the locking tightness of the door lock through the locking mode as needed, thereby achieving flexible adjustment of NVH performance.

[0169] VDC can acquire device status parameters (hereinafter referred to as the sixth status parameter) used to identify the locking mode switch status. When the sixth status parameter meets the corresponding first condition, it is determined that the vehicle is in the locking mode; when the sixth status parameter meets the corresponding second condition, it is determined that the vehicle is in the locking mode.

[0170] Optionally, the vehicle may provide an option to turn the locking mode on or off via a control center or desktop interface, which the user can activate or deactivate by triggering the option. Alternatively, the vehicle may provide a mechanical button for turning the locking mode on or off, which the user can operate to activate or deactivate the locking mode. Alternatively, the user can also control the vehicle to turn the locking mode on or off via remote control options provided on other devices.

[0171] That is, the sixth state parameter may include the received operation command, the first condition may include the received operation command indicating to open the locking mode, and the second condition may include the received operation command indicating to close the locking mode.

[0172] The operation instructions may include, but are not limited to, touch operation instructions, voice instructions, remote control instructions, etc.; touch operation instructions may be button / click operation instructions or gesture operation instructions, etc.; this embodiment does not make any special limitations on this.

[0173] In some implementations, the second locking degree can be a fixed locking degree.

[0174] In other embodiments, the second locking degree is adjustable; that is, the vehicle provides a function to adjust the second locking degree, which the user can dynamically adjust. Similar to the on / off function of the locking mode described above, the vehicle can provide an option for adjusting the second locking degree in an interface such as a control center or desktop, which the user can activate to adjust the second locking degree. Alternatively, the vehicle can also provide a mechanical button for adjusting the second locking degree, which the user can operate to adjust the second locking degree. Alternatively, the user can also control the vehicle to adjust the second locking degree via remote control options provided on other devices.

[0175] Bumpy road conditions VDC can adjust the door locks from the first locking position to the second locking position when the vehicle is on a bumpy road, and adjust the door locks back to the first locking position when the vehicle switches to a smooth road.

[0176] Under bumpy road conditions, the vehicle body is subjected to high-frequency, high-intensity vibrations and impacts, causing slight relative displacement between the door and the body, which weakens the sealing effect of the door seals. In the above embodiment, increasing the door lock tightness when the vehicle is on a bumpy road enhances the rigid connection between the door and the body, suppresses relative movement, and improves sealing reliability and NVH performance under bumpy road conditions. Furthermore, when the vehicle switches to a smooth road surface, resetting the door lock tightness reduces the mechanical load on the door lock system in situations where high sealing requirements are not required, thus helping to extend the service life of related components. It also reduces the rebound force when opening the door subsequently, improving the user experience.

[0177] VDC can acquire device status parameters (hereinafter referred to as the seventh status parameter) used to identify bumpy road conditions. When the seventh status parameter meets the corresponding first condition, it is determined that the vehicle is on a bumpy road; when the seventh status parameter meets the corresponding second condition, it is determined that the vehicle is on a smooth road.

[0178] The seventh state parameter may include sensor data (referred to here as third sensor data) that can be used to identify road conditions. A first condition may include the third sensor data indicating that the vehicle is on a bumpy road, and a second condition may include the third sensor data indicating that the vehicle is on a smooth road. The third sensor data may include, but is not limited to: vertical acceleration detected by an IMU or accelerometer, suspension travel detected by suspension system sensors, and road surface data detected by a camera or lidar. The VDC may use one or more sensor data to identify road conditions. For example, it may determine that the vehicle is on a bumpy road when multiple conditions are met: vertical acceleration is greater than a first acceleration, suspension travel is greater than a preset travel, and road surface data indicates the presence of potholes. This application does not specifically limit the road condition identification method.

[0179] Optionally, the second locking degree can be a preset locking degree, such as the maximum locking degree. The specific size of the second locking degree is not specifically limited here.

[0180] Strong wind scene VDC can adjust the door locks from the first locking level to the second locking level when the vehicle is in a windy environment; and adjust the door locks back to the first locking level when the vehicle leaves the windy environment.

[0181] In windy conditions, high-speed airflow generates significant dynamic wind pressure on the vehicle body, especially in the door area. This wind pressure can not only produce wind noise at door gaps but also cause slight door deformation, weakening the sealing effect of the weatherstripping. In the above implementation, increasing the door lock tightness when the vehicle is in a windy environment enhances the fit between the door and the vehicle body, improving the door's sealing effect and thus suppressing wind noise and improving NVH performance. Furthermore, after the vehicle leaves the windy environment, resetting the door lock tightness reduces the mechanical load on the door lock system in conditions where high sealing requirements are not necessary, helping to extend the lifespan of related components. It also reduces the rebound force when opening the door subsequently, improving the user experience.

[0182] VDC can acquire device status parameters (hereinafter referred to as the eighth status parameter) used to identify strong wind scenarios. When the eighth status parameter meets the corresponding first condition, it is determined that the vehicle is in a strong wind scenario; when the eighth status parameter meets the corresponding second condition, it is determined that the vehicle has exited the strong wind scenario.

[0183] The eighth state parameter may include sensor data (referred to here as the fourth sensor data) that can be used to identify windy conditions. The first condition may include the fourth sensor data indicating that the vehicle is in a windy condition, and the second condition may also include the fourth sensor data indicating that the vehicle is in a windy condition. The fourth sensor data may include, but is not limited to: lateral acceleration detected by an IMU or accelerometer, yaw rate detected by a yaw rate sensor, etc. The VDC may use one or more sensor data to identify road conditions. For example, it may determine that the vehicle is on a bumpy road if one or more of the following conditions are met: lateral acceleration greater than a second acceleration, and yaw rate greater than a preset angular velocity. This application does not specifically limit the road condition identification method.

[0184] Optionally, the second locking degree can be a preset locking degree, such as the maximum locking degree. The specific size of the second locking degree is not specifically limited here.

[0185] The above describes some possible scenarios for adjusting the locking degree. It is understood that dynamic adjustment of the locking degree can also be applied to other scenarios, and this embodiment does not make any special limitations on this.

[0186] In some embodiments, when the door lock is in the second locking position, the VDC can adjust the door lock to the first locking position in response to the door opening operation. This can effectively release the elastic potential energy accumulated by the sealing strip due to the large compression, significantly reduce the impact and rebound force caused by excessively rapid rebound at the moment of opening the door, thereby reducing abnormal noise during the door opening process, making the door opening action smoother and quieter, and thus improving the user experience.

[0187] Door opening operations may include, but are not limited to: pressing the mechanical / electronic door lock button on the vehicle, pulling the door handle on the door, issuing an opening command via a display screen, voice command, or remote control application, etc.

[0188] The first locking degree can be the initial locking degree when the car door is closed.

[0189] It is understood that any of the above examples can be considered an independent solution, or any combination of the above examples can also be considered an independent solution. This application does not impose any particular restrictions here.

[0190] In the above solution, the sealing effect between the door and the equipment body can be adjusted by dynamically regulating the locking tightness of the door lock, thus flexibly responding to users' differentiated NVH performance needs in different scenarios. Furthermore, by actively increasing the locking tightness, the overall sealing effect and NVH performance of the equipment can be effectively enhanced in external environments with high noise, high airflow disturbance, or high humidity, significantly reducing the impact of external interference (such as changes in airflow pressure, rain / water flow impact, etc.) on the equipment's sealing performance, thereby improving the overall environmental adaptability and reliability of the equipment. At the same time, this mechanism also provides users with a quieter and more intelligent user experience.
