Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to a vehicle and locking module, locking mechanism, locking control method, and locking control device. Background Technology

[0002] The carrier includes a mounting frame and an isolation component, such as a door. A sealing element is provided between the isolation component and the mounting frame. When the isolation component is closed, the sealing element is compressed and contracts to ensure the sealing performance of the carrier at the isolation component. However, when the carrier is operating at high speed, a relatively large pressure difference exists between the inside and outside of the carrier. This pressure difference acts on the sealing element, which may cause the seal to fail.

[0003] Therefore, how to provide a solution to overcome or alleviate the above-mentioned defects remains a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0004] To address the aforementioned technical problems, this application provides a vehicle and locking module, locking mechanism, locking control method, and locking control device. The locking module's locking tongue has multiple locking positions, and the limiting unit has multiple limiting states, so as to support and limit the locking tongue in different locking positions, thereby providing different levels of locking force and thus providing different degrees of sealing, so as to better meet the requirements of use and improve the user experience.

[0005] In a first aspect, embodiments of this application provide a locking module, specifically applicable to a vehicle, capable of locking between an isolation component and a mounting frame. The locking module includes a locking mechanism and a latch. The locking mechanism includes a latch, a drive unit, and a limiting unit. The latch includes an engaging portion. The latch switches between an unlocked position and a locked position, with at least two locked positions; wherein, in the locked position, the engaging portion locks with the latch. The drive unit and the latch are drive-coupled. The limiting unit includes at least two limiting states, with each limiting state limiting the latch in a different locked position.

[0006] In the above solution, the latch has multiple locking positions, and the limiting unit has multiple limiting states. The limiting unit in different limiting states can support and limit the latch in different locking positions, thus controlling the latch at different locking positions. It is known that the locking force exerted by the latch on the latch is different at different locking positions, and correspondingly, the compression of the sealing element between the two parts to be locked is also different. Therefore, by adjusting the locking position of the latch, different degrees of sealing can be provided, better meeting usage requirements and improving the user experience.

[0007] Taking the locking module applied to the locking between the isolation component and the mounting frame of a vehicle as an example, when the isolation component switches from the open to the closed state, a locking position with a relatively small locking force can be selected to reduce the compression of the sealing element, thereby reducing closing noise and improving the user experience at the moment of closing. Simultaneously, adjusting the compression of the sealing element to a relatively small amount also helps to ensure the service life of the sealing element. When the vehicle is operating at high speed, a locking position with a relatively large locking force can be selected to increase the compression of the sealing element, thereby improving the sealing performance between the isolation component and the mounting frame. This effectively reduces wind noise during high-speed operation and improves the user experience. Therefore, when the locking module is applied to a vehicle, it can balance the user experience during both the closing moment and high-speed operation, resulting in a vehicle with relatively better performance.

[0008] In the embodiments of this application, the number of limit states and the number of locking positions are the same, and the limit units in each limit state and the locking tongues in each locking position can be set in a one-to-one correspondence, so that the locking tongues in each locking position can be effectively supported and limited.

[0009] It should be understood that the locking module provided in this application is not limited to application in vehicles. In fact, the locking module can be applied in any scenario where locking is required. That is to say, this application does not actually limit the specific application scenario of the locking module.

[0010] In some possible implementations, the limiting unit includes an adjustable component; the shape or position of the adjustable component can be adjusted to switch the limiting state of the limiting unit, thereby enabling it to support and limit the bolt in different locking positions. In specific implementations, the bolt in each locking position may be supported and limited by the adjustable component; alternatively, the bolt in some locking positions may be supported and limited by the adjustable component, while the bolt in other locking positions may be supported and limited by other components of the limiting unit.

[0011] In some possible implementations, the limiting unit also includes a driving component, which is drively connected to the adjustable component to drive the adjustable component to change its position.

[0012] Here, "transmission connection" refers to the transmission of mechanical force between the driving component and the adjustable component, so that the adjustable component can be driven to change position by the action of this mechanical force. With this setting, this implementation method does not have special requirements for the specific material of the adjustable component, making it relatively easy to obtain and relatively low in manufacturing cost.

[0013] In some possible implementations, the limiting unit also includes a driving component, which is driven to connect with the adjustable component to change the shape of the adjustable component.

[0014] In practical operation, the driving component can apply external excitation to the adjustable component to drive it to deform, such as extend or retract, thereby changing the shape of the adjustable component to support and limit the latch in different locking positions. In this implementation, the deformation of the adjustable component mainly relies on its own material properties, and the connection structure between the driving component and the adjustable component can be relatively simple.

[0015] In this implementation, the driving component is the excitation source, the adjustable component is the responder, and the "driving connection" is a signal transmission and reception response coordination established between the excitation source and the responder, which involves excitation signal transmission, excitation signal reception, and excitation signal response.

[0016] In this implementation, the adjustable component can be an electrodeformable device, such as piezoelectric ceramics or electrostrictive ceramics, and the driving component can be a power supply device to apply electrical excitation to the adjustable component. Alternatively, the adjustable component can be a photodeformable device, such as photodeformable photosensitive polymers, and the driving component can be a light source device to apply optical excitation to the adjustable component. Alternatively, the adjustable component can be a magnetodeformable device, such as rare-earth supermagnetostrictive materials (e.g., terbium-dysprosium-iron alloys), iron-cobalt-vanadium alloys, magnetostrictive shape memory alloys, etc., and the driving component can be a magnet, such as an electromagnet, to apply magnetic excitation to the adjustable component. Alternatively, the adjustable component can also be a thermodeformable device, such as shape memory alloys, and the driving component can be a temperature control device, such as a liquid bath heating device or an electric heating device, to apply thermal excitation to the adjustable component.

[0017] In some possible implementations, the driving component is configured to drive the adjustable component to translate, thereby driving the adjustable component to change its position through translation.

[0018] In some possible implementations, the driving components include a rotary drive module and a displacement conversion module. The rotary drive module can output rotary displacement. The rotary drive module can be connected to the adjustable component through the displacement conversion module, which can be, for example, a gear and rack structure or a lead screw structure, so as to convert the rotary displacement directly output by the rotary drive module into the linear displacement required by the adjustable component, thereby driving the adjustable component to translate.

[0019] It should be understood that in some other implementations of the embodiments of this application, the driving component may also be a linear drive module that can directly output linear displacement, such as a linear cylinder or a linear hydraulic cylinder, so as to directly drive the adjustable component to translate, which is also feasible.

[0020] In some possible implementations, the drive component is configured to drive the adjustable component to rotate, thereby causing the adjustable component to change position through rotation.

[0021] In some possible implementations, the driving component includes a rotary drive module. The rotary drive module is connected to the adjustable component and can directly output rotational displacement to directly drive the adjustable component to rotate.

[0022] It should be understood that in some other implementations of the embodiments of this application, the adjustable component can be rotatably configured, and the driving component can be a linear drive module capable of directly outputting linear displacement, such as a linear cylinder or linear hydraulic cylinder. This linear drive module includes a linear drive shaft, which can drive the adjustable component to rotate. In this implementation, the linear drive shaft and the adjustable component can be in abutting fit or a rotating connection, etc., to avoid interference between the linear displacement of the linear drive shaft and the rotational displacement of the adjustable component.

[0023] In some possible implementations, the rotary drive module includes a first operating mode and a second operating mode; in the first operating mode, the rotary drive module has a first rotary output direction; in the second operating mode, the rotary drive module has a second rotary output direction, and the first rotary output direction and the second rotary output direction are opposite.

[0024] In the first operating mode, the rotary drive module outputs rotational power outward along the first rotational output direction, driving the adjustable component to move to the position corresponding to the first limit state. When in the first limit state, the limiting unit can abut and limit the latch in the locked position, where the locking position has a relatively large locking force. In the second operating mode, the rotary drive module outputs rotational power outward along the second rotational output direction, driving the adjustable component to move to the position corresponding to the second limit state. When in the second limit state, the limiting unit can abut and limit the latch in the locked position, where the locking position has a relatively small locking force. Thus, by switching between the first and second operating modes, the drive unit can flexibly adjust the setting position of the adjustable component to change the limiting state of the limiting unit, thereby facilitating the limiting of the latch in different locking positions.

[0025] In some possible implementations, the rotary drive module includes an input wheel, a ratchet assembly, and a pawl assembly. The input wheel is capable of inputting rotational power and is provided with a first drive unit and a second drive unit. The ratchet assembly includes a first ratchet and a second ratchet coaxially arranged; the first ratchet includes a first tooth, and the second ratchet includes a second tooth; the first ratchet has a first anti-rotation direction, and the second ratchet has a second anti-rotation direction, which are opposite to each other. The pawl assembly includes a first pawl and a second pawl; the first pawl is configured to mesh with the first tooth, and the second pawl is configured to mesh with the second tooth; both the first and second pawls are configured to slide to adjust the meshing state with the first and second teeth.

[0026] In the first operating mode of the rotary drive module, the input wheel rotates along the first anti-rotation direction. At this time, the first drive unit drives the first pawl to slide, disengaging it from the first gear tooth, thus releasing the anti-rotation limit between the first pawl and the first ratchet, allowing rotational power to be smoothly transmitted to the adjustable component. In the second operating mode of the rotary drive module, the input wheel rotates along the second anti-rotation direction. At this time, the second drive unit drives the second pawl to slide, disengaging it from the second gear, thus releasing the anti-rotation limit between the second pawl and the second ratchet, allowing rotational power to be smoothly transmitted to the adjustable component. In other words, regardless of whether the rotary drive module is in the first or second operating mode, rotational power can be smoothly transmitted from the input wheel to the adjustable component to drive its displacement.

[0027] After the adjustable component's position adjustment is complete and it effectively supports and limits the latch, the sealing element always possesses an elastic restoring force that returns to its uncompressed state. This elastic restoring force acts on the latch and is transmitted to the input wheel through the latch and the adjustable component. When this force causes the input wheel to tend to move in the first anti-rotation direction, the first pawl and the first ratchet engage to prevent the input wheel from rotating, thus suppressing the aforementioned movement tendency. When this force causes the input wheel to tend to move in the second anti-rotation direction, the second pawl and the second ratchet engage to prevent the input wheel from rotating, also suppressing the aforementioned movement tendency. In other words, the cooperation of the ratchet and pawl groups can also effectively limit the transmission of rotational power from the adjustable component to the input wheel. This ensures that the positions of the adjustable component and the latch remain unchanged, improves the locking reliability of the latch, and largely avoids the situation where the sealing element is compressed and then accidentally released, thus better ensuring the sealing effect of the carrier 100.

[0028] In some possible implementations, the first pawl includes a first driving surface, which can be a plane, an arcuate surface, a combination of two planes, or a combination of a plane and an arcuate surface, etc. At least a portion of the first driving surface forms an angle with the sliding direction of the first pawl. The first driving part is configured to drive the first pawl to slide via the first driving surface, so that the first pawl can disengage from the first gear teeth, thereby releasing the anti-rotation limit between the first pawl and the first ratchet.

[0029] It should be understood that in some other implementations of the embodiments of this application, the first driving surface may also be disposed on the first driving part, or the first driving surface may be disposed on both the first driving part and the first pawl.

[0030] In some possible implementations, the second pawl includes a second driving surface, which can be a plane, an arcuate surface, a combination of two planes, or a combination of a plane and an arcuate surface, etc. At least a portion of the second driving surface forms an angle with the sliding direction of the second pawl. The second driving part is configured to drive the second pawl to slide via the second driving surface, so that the second pawl can disengage from the second gear teeth, thereby releasing the anti-rotation limit between the second pawl and the second ratchet.

[0031] It should be understood that in some other implementations of the embodiments of this application, the second driving surface may also be disposed on the second driving part, or the second driving surface may be disposed on both the second driving part and the second pawl.

[0032] In some possible implementations, the rotary drive module may also include an output shaft. The input wheel and output shaft are drive-coupled to drive the output shaft to rotate. The output shaft is also drive-coupled to drive the adjustable component to move, thereby adjusting the position of the adjustable component.

[0033] In some possible implementations, at least one of the first drive unit and the second drive unit is connected to the output shaft for driving the output shaft to rotate. In this way, the input wheel can transmit rotational power to the output shaft through the first drive unit and / or the second drive unit, without the need for additional transmission structures, thus simplifying the specific structure of the rotation drive module in this embodiment and reducing costs.

[0034] It should be understood that in some other implementations of the embodiments of this application, the input wheel and the output shaft can also be connected using other methods to transmit rotational power. For example, a connecting member in the form of a connecting shaft can be provided, and the input wheel and the output shaft can be connected through this connecting member, thus also realizing the transmission of power between the input wheel and the output shaft.

[0035] In some possible implementations, the output shaft is provided with a first slide groove, a first pawl is slidably connected to the first slide groove, and a first drive unit is configured to drive the output shaft to rotate via the inner wall of the first slide groove. With this configuration, the first slide groove can have two functions: firstly, to slide and guide the first pawl to ensure its displacement direction; secondly, to engage with the first drive unit to transmit rotational power from the first drive unit to the output shaft. This eliminates the need for additional structures on the output shaft to engage with the first drive unit, thus simplifying the structure of the output shaft.

[0036] The sliding direction of the first pawl can be, for example, the radial direction of the output shaft, or other directions, which are not limited here.

[0037] It should be understood that in some other implementations of the embodiments of this application, the first pawl may also be slidably connected to the input wheel.

[0038] In some possible implementations, the output shaft is provided with a second slide groove, and a second pawl is slidably connected to the second slide groove. The second drive unit is configured to drive the output shaft to rotate via the inner wall of the second slide groove. With this configuration, the second slide groove can have two functions: first, to slide and guide the second pawl to ensure its displacement direction; second, to engage with the second drive unit to transmit rotational power from the second drive unit to the output shaft. This eliminates the need for additional structures on the output shaft to engage with the second drive unit, thus simplifying the structure of the output shaft.

[0039] The sliding direction of the second pawl can be, for example, the radial direction of the output shaft, or other directions, which are not limited here.

[0040] It should be understood that in some other implementations of the embodiments of this application, the second pawl may also be slidably connected to the input wheel.

[0041] In some possible implementations, the output shaft includes a wheel section and a shaft body, with the radial dimension of the wheel section being larger than that of the shaft body. The wheel section can be located within the shaft body, and the two can be a single, integrally formed structure. Alternatively, the wheel section and shaft body can be machined separately and then assembled using methods such as welding, threaded connections, or interference fits. Specifically, the first and second pawls can be slidably connected to the wheel section. Using this approach, by setting the output shaft as a wheel section and a shaft body, the radial dimension of the wheel section only needs to be relatively large to allow for sliding engagement with the pawl assembly, while the radial dimension of the shaft body can be relatively small. This effectively reduces the overall size of the output shaft, thereby reducing material consumption and lowering costs.

[0042] The shaft body and the adjustable component are connected in a transmission manner to drive the adjustable component to move.

[0043] In some possible implementations, the pawl assembly further includes a first elastic element, which may be, for example, a spring, or an elastomer made of a material with a certain elastic deformation capacity, such as rubber, silicone, or latex. The first elastic element is configured to interact with the first pawl to drive it into engagement with the first ratchet. Specifically, when the first drive unit disengages the first pawl from the first gear teeth, the deformation of the first elastic element can increase to accumulate elastic potential energy; when the force exerted by the first drive unit on the first pawl is released, the accumulated elastic potential energy of the first elastic element can be released to drive the first pawl to reset, allowing it to re-engage with the first ratchet, thus ensuring the anti-rotation and limiting effect.

[0044] In specific implementation, at least one of the first pawl and the output shaft can be provided with a receiving groove. The receiving groove can accommodate a portion of the first elastic element and guide the expansion and contraction deformation of the first elastic element, which can reduce the situation of the first elastic element moving or deviating, and is more conducive to ensuring the stability and reliable use of the first elastic element.

[0045] It should be understood that in some other implementations of the embodiments of this application, the pawl assembly may also include a magnetic drive component. The magnetic drive component may include a first magnetic part and a second magnetic part. The first magnetic part may be installed on the output shaft part, and the second magnetic part may be installed on the first pawl. The magnetic poles at the opposite ends of the first magnetic part and the second magnetic part are the same to generate a repulsive force. This repulsive force may also drive the first pawl and the first ratchet to mesh. In this implementation, the first elastic element may not be provided.

[0046] In some possible implementations, the pawl assembly further includes a second elastic element, which may be, for example, a spring, or an elastomer made of a material with a certain elastic deformation capacity, such as rubber, silicone, or latex. The second elastic element is configured to interact with the second pawl to drive it into engagement with the second ratchet. Specifically, when the second drive unit disengages the second pawl from the second gear, the deformation of the second elastic element can increase to accumulate elastic potential energy; when the force exerted by the second drive unit on the second pawl is released, the accumulated elastic potential energy of the second elastic element can be released to drive the second pawl to reset, allowing it to re-engage with the second ratchet to ensure the anti-rotation and limiting effect.

[0047] In specific implementation, at least one of the second pawl and the output shaft can be provided with a receiving groove. The receiving groove can accommodate a portion of the second elastic element and guide the expansion and contraction deformation of the second elastic element, which can reduce the occurrence of the second elastic element moving or deviating, and is more conducive to ensuring the stability and reliable use of the second elastic element.

[0048] It should be understood that in some other implementations of the embodiments of this application, the pawl assembly may also include a magnetic drive component. The magnetic drive component may include a first magnetic part and a second magnetic part. The first magnetic part may be installed on the output shaft part, and the second magnetic part may be installed on the second pawl. The magnetic poles at the opposite ends of the first magnetic part and the second magnetic part are the same to generate a repulsive force. This repulsive force may also drive the second pawl and the second ratchet to mesh. In this implementation, the second elastic element may not be provided.

[0049] In some possible implementations, the limiting unit also includes a main body component, with adjustable components mounted on the main body component for integrated assembly via the main body component. This improves the integration and structural compactness of the limiting unit and facilitates its installation.

[0050] In practical implementation, the limiting unit can also be supported and limited by the main body component and a locking tongue in a locked position. In this case, the adjustable component in the limiting unit can only support and limit the locking tongue in a part of the locked position.

[0051] In some possible implementations, in the limited state, the limiting unit fixes the bolt through the main body component, which can improve the support stability and reliability of the bolt.

[0052] In some possible implementations, the main component is configured to switch between a working position and a clearance position. When the bolt is in the unlocked position, the main component is in the working position and interferes with the bolt's transition to the unlocked position. When the bolt is transitioning from the unlocked to the locked position, the bolt drives the main component to the clearance position to clear the bolt. When the bolt is in the locked position, the main component is in the working position.

[0053] In this implementation, when the bolt is in the unlocked position, the main component is in the working position. The main component interferes with the rotation of the bolt, therefore the distance between the main component and the bolt is relatively small, allowing for a more compact spatial layout and reducing the space occupied during installation. When the bolt switches to the locked position, the bolt itself can drive the main component to the avoidance position without the need for additional drive components. This also reduces the structural complexity of the limit unit, thereby lowering costs.

[0054] It should be understood that in some other implementations of the embodiments of this application, the locking module may also have an additional driving element, which is then used to drive the main component to switch positions. The specific type of driving element is related to the displacement form required by the main component, and is not limited here.

[0055] In some possible implementations, the limiting unit also includes an elastic reset element, which can be a spring, such as a linear spring or a torsion spring; or it can be a tension rope; or it can be an elastomer made of a material with a certain elastic deformation capacity, such as rubber, silicone, or latex. The elastic reset element interacts with the main component to drive the main component to move towards the working position.

[0056] Specifically, during the process of the latch switching from the unlocked position to the locked position, the main component switches from the working position to the avoidance position, the deformation of the elastic reset component increases, and elastic potential energy is accumulated; when the latch switches to the locked position, the latch releases its drive on the main component, the elastic potential energy accumulated by the elastic reset component is released, and the main component automatically switches back to the working position.

[0057] In some possible implementations, the main component is configured to rotate, allowing it to switch between a working position and a clearance position. In this implementation, the mounting structure of the main component is relatively simple, requiring only a single rotating axis to complete the installation.

[0058] It should be understood that in some other implementations of the embodiments of this application, the main component can also be configured to be capable of linear displacement, so as to switch between the working position and the avoidance position by translation; in this implementation, the isolation component or the mounting frame can be provided with sliding guide components in the form of slide rails, slide grooves, etc., to guide the sliding of the main component.

[0059] In some possible implementations, the bolt is configured to rotate to switch between an unlocked and locked position, thus simplifying bolt assembly. Alternatively, the bolt can be configured to translate, also enabling switching between the unlocked and locked positions.

[0060] In some possible implementations, the locking positions include a first locking position and a second locking position. The rotation angle of the bolt from the unlocked position to the first locking position is called the first angle. The rotation angle of the bolt from the unlocked position to the second locking position is called the second angle. The second angle is greater than the first angle.

[0061] In some possible implementations, the drive unit includes a drive lever configured to engage and drive the locking tongue.

[0062] In this implementation, the drive rod and the latch are in abutting engagement, and there is no fixed connection between them. This allows the drive unit to reset after driving the latch to the corresponding locking position, moving the drive rod and latch away from each other. The drive unit does not need to continuously apply force to the latch, reducing the time it spends under load. This is beneficial for extending the lifespan of the drive unit and for energy conservation and emission reduction. Furthermore, because the drive rod and latch are not fixedly connected, the latch will not switch to the unlocked position when the drive rod moves away from the latch, thus avoiding any impact on the normal locking of the latch and the latch latch.

[0063] Secondly, embodiments of this application also provide a locking mechanism, including a latch, a drive unit, and a limiting unit. The latch includes a locking portion, which switches between an unlocked position and a locked position, with at least two locking positions; wherein, in the locked position, the locking portion is configured to lock with a latch. The drive unit and the latch are drive-coupled. The limiting unit includes at least two limiting states, with the limiting unit in different limiting states limiting the latch in different locking positions.

[0064] In the above solution, the locking tongue has multiple locking positions, and the limiting unit has multiple limiting states. The limiting unit in different limiting states can support and limit the locking tongue in different locking positions, so as to control the locking tongue in different locking positions, thereby providing different degrees of sealing, so as to better meet the requirements of use and improve the user experience.

[0065] Thirdly, this application also provides a vehicle, which can be a transportation vehicle, such as a vehicle, ship, or aircraft. The vehicle includes a vehicle body and an isolation component. The vehicle body includes a mounting frame, which can specifically be a door frame. The isolation component can be a side door, tailgate, top door, or a hood. At least one of the isolation component and the mounting frame is provided with a sealing element in the form of a sealing ring to achieve a seal between the isolation component and the mounting frame in the closed state. The vehicle also includes a locking module involved in the first aspect or any of the implementations of the first aspect, wherein one of the locking mechanism and the latch of the locking module is installed on the isolation component and the other is installed on the vehicle body.

[0066] Since the aforementioned locking modules can provide different levels of sealing, the locking modules can be adjusted as needed during vehicle use, thereby enabling the vehicle to achieve different sealing levels to better meet usage requirements and improve the user experience.

[0067] For example, when the isolating component switches from the open to the closed state, the latch can be switched to a locking position with relatively low locking force to reduce the compression of the sealing element, thereby reducing closing noise and improving the user experience at the moment of closing. Simultaneously, adjusting the compression of the sealing element to a relatively small amount helps ensure its service life. It is understood that the above situation typically occurs when the vehicle is stationary or operating at low speed. Conversely, when the vehicle is operating at high speed, the latch can be switched to a locking position with relatively high locking force to increase the compression of the sealing element, thereby improving the sealing performance between the isolating component and the mounting frame. This effectively reduces wind noise during high-speed operation and improves the user experience. In other words, the vehicle provided in this application embodiment offers a relatively better user experience both at the moment of closing and during high-speed operation, resulting in superior performance.

[0068] Fourthly, embodiments of this application also provide a locking control method applicable to the locking module involved in the first aspect or any of the implementations of the first aspect. The locking control method includes: acquiring feature information, the feature information including at least one of speed information and road condition information; determining a target locking position based on the feature information; controlling the movement of the locking tongue based on the target locking position; and controlling a limiting unit to switch to a limiting state corresponding to the target locking position based on the target locking position, wherein the locking tongue is limited by the limiting unit to the target locking position.

[0069] With this configuration, during vehicle use, the target locking position of the latch and the limiting state of the limiting unit can be adjusted according to different feature information, so as to adjust the locking force between the latch and the latch, and thus adjust the compression of the sealing element, which can meet different usage needs and better improve the user experience.

[0070] In some possible implementations, determining the target locking position based on feature information includes: determining the target locking position as a second locking position when the vehicle speed is greater than or equal to a preset speed; wherein the locking position includes a first locking position and a second locking position; in the first locking position, the locking force between the bolt and the latch is a first locking force; in the second locking position, the locking force between the bolt and the latch is a second locking force, and the second locking force is greater than the first locking force.

[0071] With this configuration, when the vehicle's speed is greater than or equal to the preset speed (i.e., when the vehicle is at high speed), the latch can be adjusted to the second locking position to provide greater locking force to the latch. This increases the compression of the sealing element, improving sealing performance and reducing wind noise, thus enhancing the user experience when the vehicle is operating at high speed. When the vehicle's speed is less than the preset speed (i.e., when the vehicle is relatively slow or stationary), the target locking position can be the first locking position. In this case, the compression of the sealing element can be relatively smaller, resulting in less noise from the closing mechanism and improving the user experience during closing. Furthermore, adjusting the compression of the sealing element to a relatively smaller value also helps ensure the lifespan of the sealing element.

[0072] In some possible implementations, the latch is configured to rotate to switch between an unlocked position, a first locked position, and a second locked position. The rotation angle of the latch from the unlocked position to the first locked position is a first angle. The rotation angle of the latch from the unlocked position to the second locked position is a second angle, which is greater than the first angle, in order to provide a greater locking force in the second locked position.

[0073] In some possible implementations, the target locking position is determined based on feature information, including: when the road condition information indicates that the current road segment is a flooded road condition, the target locking position is determined as a third locking position; wherein the locking position includes a first locking position and a third locking position, in the first locking position, the locking force between the latch and the latch is a first locking force, and in the third locking position, the locking force between the latch and the latch is a third locking force, and the third locking force is greater than the first locking force.

[0074] With this configuration, when the vehicle is in a water-crossing condition, the latch can be moved to the third locking position to provide greater locking force to the latch, thereby increasing the compression of the sealing element, improving sealing performance, and enhancing the vehicle's water-crossing ability.

[0075] Fifthly, embodiments of this application also provide a locking control device, applicable to locking control of the locking module involved in any of the aforementioned first aspects or implementations of the first aspect. The locking control device includes: an acquisition module for acquiring feature information, the feature information including at least one of speed information and road condition information; a determination module, communicatively connected to the acquisition module, for receiving the feature information and determining a target locking position based on the feature information; a first execution module, communicatively connected to the determination module, for receiving target locking information and controlling the movement of the locking tongue based on the target locking position; and a second execution module, communicatively connected to the determination module, for receiving target locking information and controlling a limiting unit to switch to a limiting state corresponding to the target locking position based on the target locking position, wherein the locking tongue is limited by the limiting unit to the target locking position.

[0076] With this configuration, during vehicle use, the locking control device can adjust the target locking position of the latch through the first execution module and the limit state of the limit unit through the second execution module, based on different characteristic information. This allows for adjustment of the locking force between the latch and the latch, thereby adjusting the compression of the sealing element. This can meet different usage requirements and better improve the user experience. Attached Figure Description

Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0085] Please refer to Figure 1 , Figure 1 This is a structural schematic diagram of a vehicle.

[0086] This application provides a vehicle 100, which can be, for example, a transportation vehicle. Figure 1 The vehicles shown can also include, for example, ships, airplanes, etc. For ease of description, the following embodiments of this application mainly use the vehicle 100 as an example for illustration. The vehicle can be, for example, a conventional fuel vehicle equipped only with an engine, or, for example, a pure electric vehicle equipped only with an electric motor, or, for example, a hybrid vehicle equipped with both an engine and an electric motor, etc., without limitation.

[0087] The vehicle 100 includes a vehicle body 110 and an isolation component 120.

[0088] The vehicle body 110 serves as the skeleton of the vehicle 100. When the vehicle 100 is a vehicle, the vehicle body 110 can also be referred to as the vehicle body. The interior of the vehicle body 110 contains compartments (not shown in the figure). These compartments can be passenger cabins or cargo cabins, used to accommodate passengers or cargo to realize the transportation function of the vehicle 100. Alternatively, these compartments can be functional compartments, used to accommodate the functional components of the vehicle 100 itself, such as a power system.

[0089] The isolation component 120 is installed on the vehicle body 110. The isolation component 120 has a closed state and an open state. In the closed state, the isolation component 120 can cover the aforementioned compartment, achieving a certain degree of isolation between the compartment and the external environment. This reduces the intrusion of moisture, dust, and other foreign objects from the external environment into the compartment, thereby protecting passengers, cargo, and functional devices located inside the compartment. In the open state, the isolation between the external environment and the compartment can be removed. When the compartment is a passenger cabin or cargo hold, it facilitates the entry and exit of passengers and cargo. When the compartment is a functional compartment, it facilitates the installation, maintenance, or repair of relevant functional devices.

[0090] Here, the embodiments of this application do not limit the specific type of the isolation component 120. In practical applications, those skilled in the art can determine it based on the type, model, etc., of the carrier 100. For example, see... Figure 1 The aforementioned isolation component 120 may include one or more doors such as a side door 121, a tailgate 122, and a top door 123. Furthermore, the isolation component 120 may also include a hood 124. The side door 121 specifically refers to a door located in the width direction of the vehicle 100; generally, the side door 121 may include a front door 121A and a rear door 121B, which can be arranged in the length direction of the vehicle body 110; of course, when the dimensions of the vehicle 100 in the front-rear direction are relatively small, only one of the front door 121A and rear door 121B may exist. The tailgate 122 is located at the rear of the vehicle body 110 and can also be called a trunk door. The top door 123 is located at the top of the vehicle body 110 and can also be called a sunroof. The hood 124 is located at the end of the vehicle body 110 opposite to the tailgate 122, that is, at the front end of the vehicle body 110.

[0091] It should be understood that, in addition to the vehicle body 110 and the isolation component 120, the vehicle 100 may also include other components, such as a power system, transmission system, braking system, suspension system, steering system, electrical system, etc. These systems are not the focus of improvement in this application embodiment, so they will not be described in detail in this application embodiment. For specific design, please refer to the relevant technology.

[0092] Please refer to Figure 2 , Figure 2 This is a partial schematic diagram of the vehicle body at the mounting frame.

[0093] like Figure 2 As shown, the vehicle body 110 includes a mounting frame 111. Optionally, the mounting frame 111 may also be provided with a sealing element 130, which may be, for example, a sealing ring or other flexible body with a certain degree of flexibility and deformability.

[0094] The vehicle 100 is also equipped with a locking module (not shown in the figure). When the isolation component 120 is in the closed state, the locking module can lock the isolation component 120 and the mounting frame 111. In this state, the isolation component 120 can cooperate with the mounting frame 111 to compress the sealing element 130, thereby achieving a sealed isolation between the inside and outside of the vehicle 100. This solution improves the protective effect, better reducing the intrusion of foreign objects into the interior of the vehicle 100; it also provides the vehicle 100 with relatively good sound insulation, significantly enhancing the user experience.

[0095] It should be understood that in some other implementations of the embodiments of this application, the sealing element 130 may also be disposed on the isolation component 120; or, the sealing element 130 may be disposed on both the isolation component 120 and the mounting frame 111.

[0096] In related technologies, after the locking module locks the isolation component and the mounting frame, the compression of the sealing element remains constant. This results in a relatively large pressure difference between the inside and outside of the vehicle when it is operating at high speed. This pressure difference acts on the sealing element, potentially causing seal failure and generating significant wind noise, which in turn degrades the user experience. To address this, related technologies propose increasing the compression of the sealing element during the switching process from the open to the closed state of the isolation component to ensure sealing performance during high-speed operation. However, if the compression of the sealing element is too large, the switching process from the open to the closed state will generate relatively large closing noise, which will also affect the user experience.

[0097] To address this, this application provides a locking module, please refer to the following for details. Figures 3-5 , Figure 3 This is a structural diagram of a locking module, in which the locking tongue is in the unlocked position; Figure 4 This is a schematic diagram of the locking bolt when it is in the first locked position. Figure 5 This is a schematic diagram of the locking bolt in the second locked position.

[0098] like Figure 3 As shown, the locking module 140 includes a locking mechanism 1000 and a latch 2000.

[0099] Of the locking mechanism 1000 and the latch 2000, one can be disposed on the isolation component 120 and the other can be disposed on the mounting frame 111. In this way, when the locking mechanism 1000 and the latch 2000 are locked, the isolation component 120 and the mounting frame 111 can be pressed together, thereby compressing the sealing element 130.

[0100] The locking mechanism 1000 includes a locking tongue 1100, a drive unit 1200, and a limiting unit 1300. The locking tongue 1100 includes a locking part 1110.

[0101] In some implementations, the latch 1100 is configured to rotate to switch between an unlocked position and a locked position. In the unlocked position, such as... Figure 3 As shown, the latch 2000 can be inserted into or disengaged from the locking part 1110 to accommodate the switching of the isolation member 120 between the open and closed states. In the locked position, as Figure 4 and Figure 5 As shown, the locking part 1110 of the latch 1100 and the latch 2000 are locked together. The latch 1100 can limit the latch 2000 and prevent the latch 2000 from disengaging from the locking part 1110. In this way, the locking between the isolation component 120 and the mounting frame 111 can be achieved in the closed state.

[0102] In this embodiment, the number of locking positions is at least two. The rotation angle of the latch 1100 when switching from the unlocked position to different locking positions is different, and the locking force applied by the latch 1100 to the latch 2000 is also different. Correspondingly, the compression of the sealing element 130 can also be different, thereby achieving different degrees of sealing.

[0103] With this configuration, the locking position of the latch 1100 can be adjusted according to different scenarios during the use of the vehicle 100, thereby meeting different sealing requirements. For example, when the isolating component 120 is switching from the open state to the closed state, a locking position with relatively low locking force can be selected, and the latch 1100 can be switched to this locking position to reduce the compression of the sealing element 130, thereby reducing closing noise and improving the user experience when the isolating component 120 is closed. At the same time, adjusting the compression of the sealing element 130 to a relatively small value helps to ensure the service life of the sealing element 130. It can be seen that the above situation usually occurs when the vehicle 100 is stationary or running at low speed. For example, when the vehicle 100 is operating at high speed, a locking position with a relatively large locking force can be selected, and the locking tongue 1100 can be switched to this locking position to increase the compression of the sealing element 130. This improves the sealing performance between the isolation component 120 and the mounting frame 111, effectively reducing wind noise of the vehicle 100 at high speed and enhancing the user experience. In other words, the vehicle 100 provided in this embodiment can provide a relatively better user experience both when the isolation component 120 is closed and during high-speed operation, resulting in better performance for the vehicle 100.

[0104] In some implementation methods, combined Figure 3 and Figure 4 The locking tongue 1100 can have a first locked position, and the rotation angle of the locking tongue 1100 when switching from the unlocked position to the first locked position is a first angle α1. Combined with... Figure 3 and Figure 5 The locking tongue 1100 may have a second locking position. The rotation angle of the locking tongue 1100 when switching from the unlocking position to the second locking position is the second angle α2. The second angle α2 is greater than the first angle α1. Accordingly, the locking force that the locking tongue 1100 can provide in the second locking position is greater than the locking force that the locking tongue 1100 can provide in the first locking position.

[0105] With this configuration, when the isolation component 120 switches from the open state to the closed state, the latch 1100 can be switched to the first locking position to reduce the compression of the sealing element 130, thereby effectively controlling the closing noise; when the vehicle 100 is in a high-speed running state, the latch 1100 can be switched to the second locking position to increase the compression of the sealing element 130, thereby improving the sealing performance and reducing wind noise.

[0106] It should be understood that the locking position is not limited to the aforementioned first and second locking positions. The locking tongue 1100 can also have more locking positions, such as a third locking position, a fourth locking position, etc. In this way, the locking tongue 1100 can have higher adjustability to adapt to different scenarios faced by the vehicle 100 during operation, thereby greatly improving the user experience. For example, the locking tongue 1100 can also have a third locking position. The rotation angle of the locking tongue 1100 when switching from the unlocked position to the third locking position is the third angle, which is greater than the second angle. That is, the locking tongue 1100 in the third locking position can provide a greater locking force than the locking tongue 1100 in the second locking position. In this case, the high-speed operation state can also be graded, including a first-level state and a second-level state. The speed in the second-level state can be greater than the speed in the first-level state. When the vehicle 100 is in the first-level state, the locking tongue 1100 can be in the second locking position. When the vehicle 100 is in the second-level state, the locking tongue 1100 can be in the third locking position, so as to adjust the compression of the sealing element 130 according to the different high-speed operation states.

[0107] Here, the embodiments of this application do not limit the specific structural form of the locking part 1110. In practical applications, those skilled in the art can choose according to specific needs, as long as it can meet the requirements of use. For example, the locking part 1110 can be a recessed part in the form of a lock groove, lock hole, etc., and the latch 2000 can include a protruding part in the form of a lock block, lock pin, etc., and the protruding part of the latch 2000 can be inserted into the locking part 1110. As another example, the locking part 1110 can be a protruding part in the form of a lock block, lock pin, etc., and the latch 2000 can be provided with a recessed part in the form of a lock groove, lock hole, etc., and the locking part 1110 can be inserted into the recessed part of the latch 2000.

[0108] The drive unit 1200 is configured to drively couple with the latch 1100 for switching the position of the latch 1100.

[0109] In some implementations, such as Figure 3 As shown, the drive unit 1200 may include a first power generation unit 1210, a drive wheel 1220, and a drive rod 1230.

[0110] The first power generating unit 1210 can be, for example, a motor, a rotary cylinder, etc. The first power generating unit 1210 includes a first power shaft 1211, which outputs rotational power outwards. The first power generating unit 1210 can be coupled with the drive wheel 1220 to drive the drive wheel 1220 to rotate. The drive rod 1230 is connected to the drive wheel 1220, and the drive wheel 1220 can drive the locking tongue 1100 to abut against the drive rod 1230.

[0111] In this implementation, the drive rod 1230 and the latch 1100 are in abutting engagement, and there is no fixed connection between them. Thus, when the drive unit 1200 drives the latch 1100 to the corresponding locking position, the drive unit 1200 can also reset, causing the drive rod 1230 and the latch 1100 to move away from each other. The drive unit 1200 does not need to continuously apply force to the latch 1100, reducing the time the drive unit 1200 is under load. This is beneficial for extending the service life of the drive unit 1200 and for energy conservation and emission reduction. Furthermore, since the drive rod 1230 and the latch 1100 are not fixedly connected, when the drive rod 1230 moves away from the latch 1100, the latch 1100 will not switch to the unlocked position under the drive rod 1230's influence, thus avoiding any impact on the normal locking of the latch 1100 and the latch 2000.

[0112] In this implementation, the locking tongue 1100 can be reset to the unlocked position by means of elastic elements such as springs or tension ropes.

[0113] The drive rod 1230 can be rotatably connected to the drive wheel 1220. In this case, when the drive wheel 1220 rotates, the drive rod 1230 does not rotate with it, but can move in a straight line to drive the latch 2000. Alternatively, the drive rod 1230 can be fixedly connected to the drive wheel 1220. In this case, the drive rod 1230 can rotate together with the drive wheel 1220, thus also driving the bolt 1100.

[0114] Here, the embodiments of this application do not limit the connection method between the first power shaft 1211 and the drive wheel 1220. In specific implementation, those skilled in the art can choose according to specific needs, as long as it can meet the requirements of use. For example, the drive wheel 1220 can be directly installed on the first power shaft 1211 so that it can rotate directly under the drive of the first power shaft 1211. As another example, there can also be some transmission structure between the first power shaft 1211 and the drive wheel 1220 to realize the indirect connection between the first power shaft 1211 and the drive wheel 1220. Such transmission structure can be, for example, a wire drawing, a pulley, a gear, a sprocket, etc.

[0115] It should be understood that the above description of the specific structural form of the drive unit 1200 is mainly based on... Figure 3The illustration provided is an example and should not be construed as affecting the scope of implementation of the carrier 100 and locking module 140 provided in this application. The drive unit 1200 can also adopt other structural forms while satisfying its functional requirements. For example, the drive unit 1200 may not include the drive wheel 1220, and may be directly connected to the first power shaft 1211 and the drive rod 1230. Alternatively, the first power generation unit 1210 may be a linear drive module capable of directly outputting linear displacement, such as a linear cylinder or linear hydraulic cylinder. In this case, the drive rod 1230 may serve as the linear drive shaft of the first power generation unit 1210. Furthermore, the drive unit 1200 may be connected to the locking tongue 1100. In this case, the switching of the locking tongue 1100 from the unlocked position to the locked position, and the switching of the locking tongue 1100 from the locked position to the unlocked position, can both be completed under the action of the drive unit 1200.

[0116] like Figures 3-5 As shown, the limiting unit 1300 has at least two limiting states. The limiting unit 1300 in different limiting states can respectively limit the bolt 1100 in different locking positions, ensuring that the bolt 1100 can be stably placed in the corresponding locking position. It is understood that the setting of the limiting unit 1300 is a key factor in enabling the drive unit 1200 to directly release the bolt 1100 after driving it to the locking position. This ensures that the bolt 1100 will not return to the unlocked position under the action of other external forces, guaranteeing the stability and reliability of the locking mechanism. It also prevents the drive unit 1200 from being under load for extended periods, thus contributing to the service life of the drive unit 1200 and energy conservation and emission reduction.

[0117] In this embodiment, the number of limit states and the number of locking positions are the same, and the limit unit 1300 in each limit state and the locking tongue 1100 in each locking position can be set in a one-to-one correspondence, so that the locking tongue 1100 in each locking position can be effectively supported and limited.

[0118] Please refer to Figure 6 , Figure 6 This is a schematic diagram of another locking module, in which the locking tongue is in the unlocked position and the limiting unit is not shown.

[0119] In some implementations, the latch 1100 is also configured to be capable of linear displacement in order to switch between the unlocked and locked positions.

[0120] like Figure 6As shown, the drive unit 1200 may include a first drive subunit 1240 and a second drive subunit 1250. The first drive subunit 1240 and the second drive subunit 1250 can be independent of each other, and both the first drive subunit 1240 and the second drive subunit 1250 are configured to output linear displacement. The specific structural form of the first drive subunit 1240 and the second drive subunit 1250 is not limited here. In practical applications, those skilled in the art can choose according to specific needs, as long as the requirements of use are met.

[0121] When the isolation component 120 is switched to the closed state, the first drive subunit 1240 can be activated to drive the latch 1100 to move along the first direction X, thereby realizing the insertion and engagement of the latch 1100 and the latch 2000. At this time, the latch 1100 can be in a locked position, capable of locking the latch 2000. During the operation of the carrier 100, if it is necessary to adjust the compression of the sealing element 130, the second drive subunit 1250 can be activated to drive the latch 1100 to move along the second direction Y, thereby switching the locked position of the latch 1100. The second direction Y and the first direction X can form an angle, such as 90 degrees.

[0122] It should be understood that in some other implementations of the embodiments of this application, the drive unit 1200 may also adopt other structural forms, as long as they can meet the requirements of use. For example, the first drive subunit 1240 and the second drive subunit 1250 may also be integrated. For instance, the first drive subunit 1240 may be integrated into the second drive subunit 1250, so that the second drive subunit 1250 can drive the locking tongue 1100 and the first drive subunit 1240 to move synchronously along the second direction Y.

[0123] Please refer to Figures 7-10 , Figure 7 This is a schematic diagram of the structure of a limiting unit in some implementation methods; Figure 8 This is a schematic diagram of another limiting unit in some implementation methods; Figure 9 This is a schematic diagram of another type of limiting unit in some implementation methods; Figure 10 This is a schematic diagram of another limiting unit in some implementation methods.

[0124] In some implementations, such as Figures 7-10 As shown, the limiting unit 1300 may include an adjustable component 1310. The adjustable component 1310 may have different shapes in different limiting states in order to support and limit the bolt 1100 in different locking positions.

[0125] Specifically, the limiting unit 1300 may further include a driving component 1320, which can be drivenly connected to the adjustable component 1310. In operation, the driving component 1320 can apply external excitation to the adjustable component 1310 to drive it to deform along a set direction P, such as by extending or retracting, thereby changing the shape of the adjustable component 1310. In this implementation, the deformation of the adjustable component 1310 mainly relies on its own material properties, and the connection structure between the driving component 1320 and the adjustable component 1310 can be relatively simple.

[0126] In other words, in the embodiments of this application, the driving component 1320 is the excitation source, the adjustable component 1310 is the responder, and the "driving connection" is a signal transmission and reception response coordination established between the excitation source and the responder, which involves excitation signal transmission, excitation signal reception, and excitation signal response.

[0127] Here, the embodiments of this application do not limit the specific types of the driving component 1320 and the adjustable component 1310 described above. In practical applications, those skilled in the art can select according to specific needs, as long as the requirements of use are met. For example, see [link to relevant documentation]. Figure 7 The adjustable component 1310 may employ an electrostrictive device, such as piezoelectric ceramic or electrostrictive ceramic, which can generate strain under the influence of an electric field. Correspondingly, the driving component 1320 may be a power supply device for applying electrical excitation to the adjustable component 1310. For example, see [reference needed]. Figure 8 The adjustable component 1310 can be a photodeformable device, such as a photodeformable photosensitive polymer, which can change its shape under light. Correspondingly, the driving component 1320 can be a light source device to apply light excitation to the adjustable component 1310. For example, see [reference needed]. Figure 9 The adjustable component 1310 can be a magnetostrictive device, such as a rare-earth super magnetostrictive material (e.g., terbium-dysprosium-iron alloy), an iron-cobalt-vanadium alloy, or a magnetostrictive shape memory alloy, which can change shape under the influence of a magnetic field. Correspondingly, the driving component 1320 can be a magnet, such as an electromagnet, to apply magnetic excitation to the adjustable component 1310. For example, see [reference needed]. Figure 10 The adjustable component 1310 can also be a thermo-deformable device, such as a shape memory alloy, which can adapt to external temperature changes and generate strain. Correspondingly, the driving component 1320 can be a temperature control device, such as a liquid bath heating device or an electric heating device, to apply thermal excitation to the adjustable component 1310.

[0128] In this embodiment, the latch 1100 in each locking position can be supported and limited by the adjustable component 1310. Alternatively, only some locking positions may have the latch 1100 supported and limited by the adjustable component 1310, while the latch 1100 in other locking positions may be supported and limited by other components in the limiting unit 1300.

[0129] Please refer to Figure 11-14 , Figure 11 This is a schematic diagram of the fifth type of limiting unit; Figure 12 This is a schematic diagram of the sixth type of limiting unit; Figure 13 This is a schematic diagram of the structure of the seventh type of limiting unit; Figure 14 This is a schematic diagram of the eighth type of limiting unit.

[0130] In some implementations, such as Figures 11-14 As shown, the limiting unit 1300 may include an adjustable component 1310. The position of the adjustable component 1310 may be different in different limiting states, so as to support and limit the locking tongue 1100 in different locking positions.

[0131] Specifically, the limiting unit 1300 may further include a driving component 1320, which is tractively connected to the adjustable component 1310 and used to drive the adjustable component 1310 to move, thereby changing the position of the adjustable component 1310. In this implementation, the driving component 1320 can directly drive the adjustable component 1310 to move, so as to adjust the limiting state of the limiting unit 1300 by changing the position of the adjustable component 1310. Therefore, this implementation does not have special requirements for the specific material of the adjustable component 1310, so that the manufacturing cost of the adjustable component 1310 can be relatively low.

[0132] It should be understood that the "transmission connection" in the embodiments of this application is different from the aforementioned "drive connection". "Transmission connection" refers to the transmission of mechanical force between the two connected components (the aforementioned drive component 1320 and adjustable component 1310) so as to drive the adjustable component 1310 to adjust its position.

[0133] In some implementations, the drive component 1320 is configured to drive the adjustable component 1310 to translate along a set direction P, so as to change the position of the adjustable component 1310 by translation.

[0134] like Figure 11As shown, in some solutions, the drive component 1320 can be a linear drive module that can directly output linear displacement, such as a linear cylinder or linear hydraulic cylinder. This linear drive module includes a linear drive shaft, and an adjustable component 1310 can be connected to the linear drive shaft to perform linear displacement along a set direction P under the drive of the linear drive shaft. In this solution, the drive component 1320 can directly output linear displacement, and its structure can be relatively simple.

[0135] like Figure 12 As shown, in some other embodiments, the drive component 1320 may include a rotary drive module 1321 and a displacement conversion module 1322. The rotary drive module 1321 can output a rotary displacement. The rotary drive module 1321 can be connected to the adjustable component 1310 through the displacement conversion module 1322. The displacement conversion module 1322 may be, for example, a gear and rack structure, a lead screw structure, a pulley structure, etc., which can convert the rotary displacement directly output by the rotary drive module 1321 into the linear displacement required by the adjustable component 1310, thereby realizing the translational drive of the adjustable component 1310 along the set direction P.

[0136] In some implementations, the drive component 1320 is configured to drive the adjustable component 1310 to rotate, thereby changing the position of the adjustable component 1310 by rotation.

[0137] like Figure 13 As shown, in some embodiments, the drive component 1320 may include a rotary drive module 1321, which is capable of outputting rotational displacement. The rotary drive module 1321 may be connected to the adjustable component 1310 and can be used to directly drive the adjustable component 1310 to rotate.

[0138] like Figure 14 As shown, in some other solutions, the adjustable component 1310 can be rotated, and the drive component 1320 can also be a linear drive module capable of directly outputting linear displacement, such as a linear cylinder or linear hydraulic cylinder. This linear drive module includes a linear drive shaft 1323, which can drive the adjustable component 1310 to rotate. In this solution, the linear drive shaft 1323 and the adjustable component 1310 can be in a butt-fitting configuration, thus preventing interference between the linear displacement of the linear drive shaft 1323 and the rotational displacement of the adjustable component 1310. Alternatively, the linear drive shaft 1323 and the adjustable component 1310 can be connected by a rotational connection or other methods to avoid displacement interference between them.

[0139] In this embodiment, the latch 1100 in each locking position can be supported and limited by the adjustable component 1310. Alternatively, only some locking positions may have the latch 1100 supported and limited by the adjustable component 1310, while the latch 1100 in other locking positions may be supported and limited by other components in the limiting unit 1300.

[0140] The rotary drive module 1321 includes a first operating mode and a second operating mode.

[0141] In the first operating mode, the rotary drive module 1321 has a first rotary output direction. When the rotary drive module 1321 outputs rotary power outward along the first rotary output direction, the position of the adjustable component 1310 can be changed to limit it with the locking tongue 1100 in the locked position, where the locking position has a relatively large locking force. As described above... Figure 4 and Figure 5 Taking the first and second locking positions shown as examples, the locking force of the locking tongue 1100 in the second locking position is relatively large. Therefore, the rotary drive module 1321 is in the first working mode. The rotary drive module 1321 can drive the adjustable component 1310 to move so as to abut and limit the locking tongue 1100 in the second locking position.

[0142] In the second operating mode, the rotary drive module 1321 has a second rotary output direction, which is opposite to the first and second rotary output directions. When the rotary drive module 1321 outputs rotary power outward along the second rotary output direction, the position of the adjustable component 1310 can be changed to limit it with the locking tongue 1100 in the locking position, where the locking position has a relatively small locking force. As described above... Figure 4 and Figure 5 Taking the first and second locking positions shown as examples, the locking force of the locking tongue 1100 in the first locking position is relatively small. Therefore, the rotary drive module 1321 is in the second working mode. The rotary drive module 1321 can drive the adjustable component 1310 to move so as to abut and limit the locking tongue 1100 in the first locking position.

[0143] By switching between the first and second working modes, the drive unit 1200 can flexibly adjust the setting position of the adjustable component 1310 to change the limiting state of the limiting unit 1300, thereby facilitating the limiting of the latch 1100 in different locking positions.

[0144] Please refer to Figures 15-20 , Figure 15 This is a schematic diagram of the structure of a rotary drive module; Figure 16 This is a schematic diagram of an input wheel structure; Figure 17 This is a connection structure diagram of the first drive unit, the second drive unit, the ratchet group, the pawl group, and the output shaft. Figure 18 This is a diagram showing the connection structure of the first ratchet, the first pawl, and the output shaft. Figure 19 This is a diagram showing the connection structure of the second ratchet, the second pawl, and the output shaft. Figure 20 This is a projected view of the output shaft along its axial direction.

[0145] In some implementations, such as Figure 15 and Figure 17 As shown, the rotary drive module 1321 may include an input wheel 1321A, a ratchet assembly 1321B, a pawl assembly 1321C, an output shaft 1321D, and a second power generation unit 1321E.

[0146] The second power generation unit 1321E can be, for example, a motor, a rotary cylinder, etc. The second power generation unit 1321E includes a second power shaft 1321E1, which can be coupled to the input wheel 1321A to drive the input wheel 1321A to rotate. Here, this embodiment does not limit the transmission coupling method between the second power shaft 1321E1 and the input wheel 1321A. In practical applications, those skilled in the art can choose according to specific needs, as long as the requirements are met. For example, the second power shaft 1321E1 can be directly connected to the input wheel 1321A to directly drive the input wheel 1321A to rotate. Alternatively, the second power shaft 1321E1 can also be indirectly driven by gears, pulleys, sprockets, etc.

[0147] Combination Figure 16 The input wheel 1321A may include an input wheel body 1321A1. A first driving part 1321A2 and a second driving part 1321A3 may be provided on one axial side of the input wheel body 1321A1. Both the first driving part 1321A2 and the second driving part 1321A3 can be cylindrical structures, or they can be protruding structures of other shapes; no limitation is made here, as long as they meet the usage requirements. The input wheel 1321A is also coupled to the output shaft 1321D to drive the output shaft 1321D to rotate. The output shaft 1321D can be coupled to the adjustable component 1310 to drive the adjustable component 1310 to move.

[0148] Ratchet assembly 1321B may include a first ratchet 1321B1 and a second ratchet 1321B2 coaxially arranged; combined Figures 17-19The first ratchet 1321B1 may include a first gear tooth 1321B11, and the second ratchet 1321B2 may include a second gear 1321B21. The pawl assembly 1321C may include a first pawl 1321C1 and a second pawl 1321C2, wherein the first pawl 1321C1 is configured to mesh with the first gear tooth 1321B11, and the second pawl 1321C2 is configured to mesh with the second gear 1321B21.

[0149] The first ratchet 1321B1 has a first anti-rotation direction M, and the second ratchet 1321B2 has a second anti-rotation direction N. The first anti-rotation direction M and the second anti-rotation direction N can be opposite. Specifically, as shown... Figure 18 As shown, without any other external force, due to the meshing relationship between the first pawl 1321C1 and the first gear tooth 1321B11, the first pawl 1321C1 can only rotate relative to the first ratchet 1321B1 in the direction opposite to the first anti-rotation direction M (i.e., the second anti-rotation direction N), and cannot rotate along the first anti-rotation direction M; as Figure 19 As shown, without any other external force, due to the meshing relationship between the second pawl 1321C2 and the second gear tooth 1321B21, the second pawl 1321C2 can only rotate relative to the second ratchet 1321B2 in the opposite direction to the second anti-rotation direction N (that is, the first anti-rotation direction M), and cannot rotate along the second anti-rotation direction N.

[0150] The first pawl 1321C1 is configured to slide, allowing it to switch between an engagement position abutting against the first gear tooth 1321B11 and a disengaged position. In the disengaged position, the first ratchet wheel 1321B1 can no longer limit the rotation of the first pawl 1321C1 along the first anti-rotation direction M. Similarly, the second pawl 1321C2 is also configured to slide, allowing it to switch between an engagement position abutting against the second gear tooth 1321B21 and a disengaged position. In the disengaged position, the second ratchet wheel 1321B2 can no longer limit the rotation of the second pawl 1321C2 along the second anti-rotation direction N.

[0151] When the rotary drive module 1321 is in its first operating mode, the input wheel 1321A will rotate along the first anti-rotation direction M, as shown in the reference. Figure 18At this time, the first drive unit 1321A2 will drive the first pawl 1321C1 to slide, causing the first pawl 1321C1 to disengage from the first gear tooth 1321B11, thereby releasing the anti-rotation limit between the first pawl 1321C1 and the first ratchet 1321B1, allowing the rotational power to be smoothly transmitted to the output shaft 1321D. When the rotation drive module 1321 is in the second operating mode, the input wheel 1321A will rotate along the second anti-rotation direction N, referring to... Figure 19 At this time, the second drive unit 1321A3 will drive the second pawl 1321C2 to slide, causing the second pawl 1321C2 to disengage from the second gear 1321B21, thereby releasing the anti-rotation limit between the second pawl 1321C2 and the second ratchet 1321B2, allowing the rotational power to be smoothly transmitted to the output shaft 1321D. In other words, whether the rotary drive module 1321 is in the first working mode or the second working mode, the rotational power can be smoothly transmitted from the input wheel 1321A to the output shaft 1321D to effectively drive the adjustable component 1310.

[0152] As previously described, after the latch 1100 reaches the designated locking position and the adjustable component 1310 and the latch 1100 are in contact and limited, the sealing element 130 can be compressed. However, the sealing element 130 always possesses an elastic restoring force that returns to the uncompressed state. This elastic restoring force can ultimately act on the latch 1100 and, through the latch 1100 and the adjustable component 1310, act on the output shaft 1321D, causing the output shaft 1321D and the input wheel 1321A to tend to move. Combined with... Figure 18 When the output shaft 1321D tends to move in the first anti-rotation direction M, the first pawl 1321A2 and the first ratchet 1321B1 can cooperate to prevent the output shaft 1321D and the input wheel 1321A from rotating, thereby suppressing the aforementioned movement tendency. Figure 19 When the output shaft 1321D tends to move in the second anti-rotation direction N, the second pawl 1321C2 and the second ratchet 1321B2 can cooperate to prevent the rotation of the output shaft 1321D and the input wheel 1321A, and also suppress the aforementioned movement tendency. In other words, through the cooperation of the ratchet group 1321B and the pawl group 1321C, the transmission of rotational power from the output shaft 1321D to the input wheel 1321A can be better restricted. In this way, the positions of the adjustable component 1310 and the locking tongue 1100 can be kept unchanged, which can improve the locking reliability of the locking tongue 1100 and thus largely avoid the situation where the sealing element 130 is tightened and then accidentally released.

[0153] In some implementations, such as Figure 17 and Figure 18 As shown, the first pawl 1321C1 may include a first driving surface 1321C11, at least a portion of which may form an angle with the sliding direction of the first pawl 1321C1. Thus, when the input wheel 1321A rotates, the first driving part 1321A2 can apply a driving force to the first pawl 1321C1 through the first driving surface 1321C11 to drive the first pawl 1321C1 to slide, thereby releasing the anti-rotation limit between the first pawl 1321C1 and the first ratchet 1321B1.

[0154] It can be seen that the aforementioned first driving surface 1321C11 can also be disposed on the first driving part 1321A2, which can also drive the first pawl 1321C1. For example, in the aforementioned implementation in which the first driving part 1321A2 is set as a cylindrical structure, the first driving surface 1321C11 can be naturally formed on the outer wall surface of the first driving part 1321A2.

[0155] Here, the embodiments of this application do not limit the sliding direction of the first pawl 1321C1. In practical applications, those skilled in the art can select it according to specific needs, as long as it meets the requirements of use. For example, it can be combined with Figure 18 The first pawl 1321C1 can slide along a diameter direction Q of the output shaft portion 1321D.

[0156] In some implementations, such as Figure 17 and Figure 19 As shown, the second pawl 1321C2 may include a second driving surface 1321C21, at least a portion of which may form an angle with the sliding direction of the second pawl 1321C2. Thus, when the input wheel 1321A rotates, the second driving part 1321A3 can apply a driving force to the second pawl 1321C2 through the second driving surface 1321C21 to drive the second pawl 1321C2 to slide, thereby releasing the anti-rotation limit between the second pawl 1321C2 and the first ratchet 1321B2.

[0157] It can be seen that the aforementioned second driving surface 1321C21 can also be provided on the second driving part 1321A3, which can also drive the second pawl 1321C2. For example, in the aforementioned implementation in which the second driving part 1321A3 is set as a cylindrical structure, the second driving surface 1321C21 can be naturally formed on the outer wall surface of the second driving part 1321A3.

[0158] Here, the embodiments of this application do not limit the sliding direction of the second pawl 1321C2. In practical applications, those skilled in the art can select it according to specific needs, as long as it meets the requirements of use. For example, it can be combined with Figure 19 The second pawl 1321C2 can slide along a diameter direction Q of the output shaft 1321D.

[0159] In some implementations, at least one of the first drive unit 1321A2 and the second drive unit 1321A3 can be connected to the output shaft 1321D via a transmission connection. In this way, the input wheel 1321A can transmit rotational power to the output shaft 1321D via the first drive unit 1321A2 and / or the second drive unit 1321A3, eliminating the need for additional transmission structures. This simplifies the structure of the rotation drive module 1321 in this embodiment and reduces costs.

[0160] like Figure 17 and Figure 18 As shown, the output shaft portion 1321D may be provided with a first slide groove 1321D4, and the first pawl 1321C1 may be slidably connected to the first slide groove 1321D4. The first drive portion 1321A2 is configured to drive the output shaft portion 1321D to rotate through the inner wall surface of the first slide groove 1321D4. Here, the embodiments of this application do not limit the specific forming method of the first slide groove 1321D4. In practical applications, those skilled in the art can select according to specific needs, as long as it can meet the requirements of use. For example, in Figure 17 and Figure 18 In this design, the output shaft portion 1321D may further include two spaced-apart first baffles 1321D3. Both first baffles 1321D3 can be disposed on the output shaft portion 1321D, and the aforementioned first groove 1321D4 can be formed between the two first baffles 1321D3. In this design, it is possible to avoid grooving the output shaft portion 1321D, thereby reducing the impact on the strength of the output shaft portion 1321D and helping to ensure the service life of the output shaft portion 1321D. Alternatively, a groove can be directly formed on the output shaft portion 1321D to serve as the aforementioned first groove 1321D4, which is also feasible.

[0161] like Figure 17 and Figure 19As shown, the output shaft portion 1321D may be provided with a second slide groove 1321D6, and the second pawl 1321C2 may be slidably connected to the second slide groove 1321D6. The second drive portion 1321A3 is configured to drive the output shaft portion 1321D to rotate via the inner wall surface of the second slide groove 1321D6. Here, the embodiments of this application do not limit the specific forming method of the second slide groove 1321D6. In practical applications, those skilled in the art can select according to specific needs, as long as it can meet the requirements of use. For example, in Figure 17 and Figure 19 In this design, the output shaft portion 1321D may further include two spaced-apart second baffles 1321D5. Both second baffles 1321D5 can be disposed on the output shaft portion 1321D, and the aforementioned second groove 1321D6 can be formed between the two second baffles 1321D5. In this design, it is possible to avoid grooving the output shaft portion 1321D, thereby reducing the impact on the strength of the output shaft portion 1321D and helping to ensure the service life of the output shaft portion 1321D. Alternatively, a groove can be directly formed on the output shaft portion 1321D to serve as the aforementioned second groove 1321D6, which is also feasible.

[0162] It should be understood that in some other implementations of the embodiments of this application, the first driving part 1321A2 and the second driving part 1321A3 may only be used to drive the first pawl 1321C1 and the second pawl 1321C2 to slide. In this case, the input wheel 1321A and the output shaft 1321D may also be implemented in other ways to transmit rotational power. For example, a connecting member in the form of a connecting shaft may be provided, and the input wheel 1321A and the output shaft 1321D may be connected through the connecting member. In this way, power transmission between the input wheel 1321A and the output shaft 1321D can also be realized.

[0163] In some implementations, such as Figure 20 As shown, the output shaft portion 1321D may include a disc portion 1321D1 and a shaft body 1321D2, with the radial dimension of the disc portion 1321D1 being larger than that of the shaft body 1321D2. The disc portion 1321D1 may be located on the shaft body 1321D2, and the two may be an integrally formed structure. Alternatively, the disc portion 1321D1 and the shaft body 1321D2 may be machined separately and then assembled by welding, threaded connection, interference fit, or other methods, which is also feasible.

[0164] Specifically, the first pawl 1321C1 and the second pawl 1321C2 can be slidably connected to the wheel portion 1321D1. That is, the aforementioned first baffle 1321D3 and second baffle 1321D5 can both be provided on the wheel portion 1321D1 to form a first groove 1321D4 and a second groove 1321D6 on one axial side of the wheel portion 1321D1. For the implementation method of directly providing slots in the output shaft portion 1321D to form the first groove 1321D4 and the second groove 1321D6, the corresponding slots can be directly provided in the wheel portion 1321D1.

[0165] By adopting the above solution, and configuring the output shaft portion 1321D as a wheel portion 1321D1 and a shaft body 1321D2, the output shaft portion 1321D only needs to have a relatively large radial dimension of the wheel portion 1321D1 to facilitate sliding engagement with the pawl assembly 1321C, while the radial dimension of the shaft body 1321D2 can be made relatively small. This effectively reduces the overall size of the output shaft portion 1321D, thereby reducing material consumption and lowering costs.

[0166] The shaft body 1321D2 and the adjustable component 1310 are connected in a transmission manner to drive the adjustable component 1310 to move.

[0167] It should be understood that in some other implementations of the embodiments of this application, the output shaft portion 1321D may not include the wheel portion 1321D1. In this case, the first baffle 1321D3 and the second baffle 1321D5 may both be provided on an axial end face of the shaft body 1321D1 to form a first groove 1321D4 and a second groove 1321D6 on one axial side of the shaft body 1321D1. For the implementation where the first groove 1321D4 and the second groove 1321D6 are formed by directly setting a groove in the output shaft portion 1321D, the corresponding groove can be directly provided in the shaft body 1321D1.

[0168] In addition, in some other implementations of the embodiments of this application, the first pawl 1321C1 and the second pawl 1321C2 may both be slidably connected to the input wheel body 1321A1; or, of the first pawl 1321C1 and the second pawl 1321C2, one may be slidably connected to the input wheel body 1321A1, while the other may be slidably connected to the output shaft portion 1321D.

[0169] In some implementations, such as Figure 18 As shown, the pawl assembly 1321C may also include a first elastic element 1321C3.

[0170] The first elastic element 1321C3 can be, for example, a spring, or, for example, an elastomer made of a material with a certain elastic deformation capacity such as rubber, silicone, or latex. The first elastic element 1321C3 is configured to interact with the first pawl 1321C1 to drive the first pawl 1321C1 to engage with the first ratchet 1321B1. Specifically, when the first drive unit 1321A2 drives the first pawl 1321C1 to disengage from the first gear tooth 1321B11, the deformation of the first elastic element 1321C3 can increase to accumulate elastic potential energy; when the force exerted by the first drive unit 1321A2 on the first pawl 1321C1 is released, the elastic potential energy accumulated by the first elastic element 1321C3 can be released to drive the first pawl 1321C1 to reset, allowing the first pawl 1321C1 to engage with the first ratchet 1321B1 again.

[0171] In specific implementation, at least one of the first pawl 1321C1 and the shaft body 1321D2 may be provided with a receiving groove (not shown in the figure). The receiving groove can accommodate a portion of the first elastic element 1321C3 and guide the expansion and contraction deformation of the first elastic element 1321C3, which can reduce the occurrence of the first elastic element 1321C3 moving or deviating, and is more conducive to ensuring the stability and reliable use of the first elastic element 1321C3.

[0172] It should be understood that in some other implementations of the embodiments of this application, the first elastic element 1321C3 may not be provided. In this case, other types of driving elements can be configured to drive the first pawl 1321C1 to reset, thereby engaging with the first ratchet 1321B1. For example, a magnetic drive component can be configured, which may include a first magnetic part and a second magnetic part. The first magnetic part can be mounted on the shaft body 1321D4, and the second magnetic part can be mounted on the first pawl 1321C1. The magnetic poles at opposite ends of the first magnetic part and the second magnetic part are the same to generate a repulsive force. This repulsive force can also drive the first pawl 1321C1 to engage with the first ratchet 1321B1.

[0173] In some implementations, such as Figure 19 As shown, the pawl assembly 1321C may also include a second elastic element 1321C4.

[0174] The second elastic element 1321C4 can be, for example, a spring, or the first elastic element 1321C3 can be, for example, an elastomer made of a material with a certain elastic deformation capacity, such as rubber, silicone, or latex. The second elastic element 1321C4 is configured to interact with the second pawl 1321C2 to drive the second pawl 1321C2 to engage with the second ratchet 1321B2. Specifically, when the second drive unit 1321A3 drives the second pawl 1321C2 to disengage from the second gear tooth 1321B2, the deformation of the second elastic element 1321C4 can increase to accumulate elastic potential energy; when the force exerted by the second drive unit 1321A3 on the second pawl 1321C2 is released, the elastic potential energy accumulated by the second elastic element 1321C4 can be released to drive the second pawl 1321C2 to reset, so that the second pawl 1321C2 can engage with the second ratchet 1321B2 again.

[0175] In specific implementation, at least one of the second pawl 1321C2 and the shaft body 1321D2 may be provided with a receiving groove (not shown in the figure). The receiving groove can accommodate a portion of the second elastic element 1321C4 and guide the expansion and contraction deformation of the second elastic element 1321C4, which can reduce the occurrence of the second elastic element 1321C4 moving or deviating, and is more conducive to ensuring the stability and reliable use of the second elastic element 1321C4.

[0176] It should be understood that in some other implementations of the embodiments of this application, the second elastic element 1321C4 may not be provided. In this case, other types of driving elements can be configured to drive the second pawl 1321C2 to reset, thereby engaging with the second ratchet 1321B2. For example, a magnetic drive component can be configured, which may include a first magnetic part and a second magnetic part. The first magnetic part can be mounted on the shaft body 1321D4, and the second magnetic part can be mounted on the second pawl 1321C2. The magnetic poles at opposite ends of the first magnetic part and the second magnetic part are the same to generate a repulsive force. This repulsive force can also drive the second pawl 1321C2 to engage with the second ratchet 1321B2.

[0177] Please refer to Figure 21 and Figure 22 , Figure 21 This is a schematic diagram of the structure when the limiting unit and the locking tongue in the first locking position are in contact. Figure 22 This is a schematic diagram of the structure of a limiting unit when the locking tongue abuts in the second locking position.

[0178] In some implementations, such as Figure 21 and Figure 22 As shown, the limiting unit 1300 may also include a main body component 1330, and the limiting unit 1300 can be installed and fixed through the main body component 1330.

[0179] Both the adjustable component 1310 and the drive component 1320 can be mounted on the main component 1330 for integrated assembly via the main component 1330. This improves the integration and structural compactness of the limiting unit 1300 and facilitates its installation. The adjustable component 1310 can change its shape or position relative to the main component 1330.

[0180] When the limiting unit 1300 is in the limiting state, the limiting unit 1300 fixes the locking tongue 1100 through the main body component 1330.

[0181] In this implementation, the limiting unit 1300 can also be supported and limited by the main body component 1330 and a locking tongue 1100 in a locked position. In this case, the adjustable component 1310 in the limiting unit 1300 can only support and limit the locking tongue 1100 in a partial locked position. Taking the locking position including a first locking position and a second locking position as an example, such as... Figure 21 As shown, in the first locked position, the latch 1100 can be supported and limited by the main body component 1330. At this time, the adjustable component 1310 may not undergo any change in shape or position; as Figure 22 As shown, in the second locked position, the drive component 1320 can drive the adjustable component 1310 to change its shape or position, and the locking tongue 1100 can be supported and limited by the adjustable component 1310.

[0182] It should be understood that the main component 1330 is not a necessary component. In some other implementations of the embodiments of this application, the limiting unit 1300 may also include only the adjustable component 1310 and the driving component 1320, which is also feasible.

[0183] Please refer to Figures 23-25 , Figure 23 This is a structural diagram showing the lock tongue in the unlocked position and the main body component in the working position. Figure 24 This is a structural diagram showing the main body component in the avoidance position during the process of the locking tongue switching to the first locking position; Figure 25 This is a structural diagram showing the locking tongue in the first locking position and the main body component in the working position.

[0184] In some implementations, the main component 1330 is configured to be displaceable to switch between a working position and an avoidance position.

[0185] like Figure 23As shown, when the latch 1100 is in the unlocked position, the main body component 1330 can be in the working position; at this time, the main body component 1330 is on the displacement path of the latch 1100 switching from the unlocked position to the locked position, that is, the main body component 1330 will interfere with the switching of the latch 1100 to the locked position. Figure 24 As shown, when the latch 1100 is switched from the unlocked position to the locked position, the latch 1100 can generate a driving force on the main body component 1330 to drive the main body component 1330 to a clearance position, thereby avoiding interference with the displacement of the latch 1100. Figure 25 As shown, when the latch 1100 is in the locked position, the main body component 1330 can return from the avoidance position to the working position, and the limiting unit 1300 can be in the limiting state, thereby supporting and limiting the latch 1100 in the locked position.

[0186] In this implementation, when the latch 1100 is in the unlocked position and the main body 1330 is in the working position, the main body 1330 will interfere with the rotation of the latch 1100. Therefore, the distance between the main body 1330 and the latch 1100 is relatively small, and the two can be more compact in spatial layout, which can reduce the space occupied for installation. When the latch 1100 switches to the locked position, the latch 1100 itself can drive the main body 1330 to switch to the avoidance position without the need for additional drive elements. This can also reduce the structural complexity of the limit unit 1300, thereby reducing costs.

[0187] In some implementations, the limiting unit 1300 may also include an elastic reset member 1340, which can interact with the main body component 1330 to drive the main body component 1330 to move towards the working position.

[0188] With this configuration, during the process of the latch 1100 switching from the unlocked position to the locked position, the main body component 1330 can switch from the working position to the avoidance position, and the deformation of the elastic reset component 1340 can increase to accumulate elastic potential energy; when the latch 1100 switches to the locked position, the drive of the latch 1100 on the main body component 1330 is released, and the elastic potential energy accumulated by the elastic reset component 1340 can be released, which can drive the main body component 1330 to automatically switch back to the working position.

[0189] The aforementioned elastic reset element 1340 can be a spring, such as a linear spring or a torsion spring. Alternatively, the aforementioned elastic reset element 1340 can also be a tension rope. Alternatively, the aforementioned elastic reset element 1340 can also be an elastomer made of materials with a certain elastic deformation capacity, such as rubber, silicone, or latex.

[0190] In some implementations, the main component 1330 can be configured to rotate, switching between a working position and a clearance position via rotational displacement. In this implementation, the mounting structure of the main component 1330 is relatively simple, requiring only a single rotating axis to complete the mounting of the main component 1330.

[0191] In addition, the main component 1330 can also be configured to perform linear displacement, so as to switch between working position and avoidance position by translation; in this implementation, the isolation component 120 or the mounting frame 111 can be provided with sliding guide components in the form of slide rails, slide grooves, etc., to guide the sliding of the main component 1330.

[0192] It should be understood that the above description of the scheme for switching the locking tongue 1100 driving the main body component 1330 from the working position to the avoidance position is only an exemplary description made in conjunction with the accompanying drawings of the embodiments of this application. It cannot be regarded as a limitation on the implementation scope of the carrier 100 and the locking module 140 provided in the embodiments of this application. Under the condition of satisfying the function, the main body component 1330 may also adopt other driving schemes. For example, a driving element can be provided, which then drives the main body component 1330 to switch positions. The specific type of driving element is related to the displacement form required by the main body component 1330, and is not limited here. In this implementation, the driving element and the main body component 1330 can be connected. In this case, the switching of the main body component 1330 to the working position and to the avoidance position can both be driven by the driving element, without the need to provide the aforementioned elastic reset member 1340. Alternatively, in this implementation, the driving element and the main body component 1330 can also be in contact, that is, there may be no fixed connection between them. In this case, the driving force for the main body component 1330 to switch from the working position to the avoidance position and the driving force for the main body component 1330 to switch from the avoidance position to the working position can be provided by the driving element, while the other can be provided by the aforementioned elastic reset member 1340.

[0193] Please refer to Figure 26 and Figure 27 , Figure 26 This is a flowchart illustrating a locking control method. Figure 27 for Figure 26 A schematic diagram illustrating one step in the process.

[0194] like Figure 26As shown, this application embodiment also provides a locking control method applicable to the locking module 140 involved in the aforementioned implementations. The locking control method includes: step S100, acquiring feature information, the feature information including at least one of speed information and road condition information; step S200, determining the target locking position based on the feature information; step S300, controlling the movement of the locking tongue 1100 based on the target locking position; step S400, controlling the limiting unit 1300 to switch to the limiting state corresponding to the target locking position based on the target locking position, and the locking tongue 1100 is limited by the limiting unit 1300 at the target locking position.

[0195] With this configuration, during the use of the vehicle 100, the target locking position of the locking tongue 1100 and the limiting state of the limiting unit 1300 can be adjusted according to different feature information, so as to adjust the locking force between the locking tongue 1100 and the latch 2000, and thus adjust the compression of the sealing element 130, which can meet different usage needs and better improve the user experience.

[0196] Here, the embodiments of this application do not limit the execution order of steps S300 and S400. In practice, those skilled in the art can flexibly adjust the order as long as it meets the requirements of use. For example, step S300 can be executed first, and then step S400 can be executed. That is, the locking tongue 1100 can be switched to the target locking position first, and then the limiting unit 1300 can be switched to the limiting state corresponding to the target locking position. Alternatively, step S400 can be executed first, and then step S300 can be executed. That is, the limiting unit 1300 can be switched to the limiting state corresponding to the target locking position first, and then the locking tongue 1100 can be switched to the target locking position. Furthermore, steps S300 and S400 can also be executed synchronously.

[0197] In some implementations, such as Figure 27 As shown, the feature information may include speed information. Step S200 may include: Step S210, when the speed of the vehicle 100 is greater than or equal to a preset speed, determining the target locking position as a second locking position. The locking position may include a first locking position and a second locking position. In the first locking position, the locking force between the latch 1100 and the latch 2000 is a first locking force. In the second locking position, the locking force between the latch 1100 and the latch 2000 is a second locking force, and the second locking force is greater than the first locking force.

[0198] With this configuration, when the vehicle 100's speed is greater than or equal to the preset speed (i.e., when the vehicle 100 is at high speed), the latch 1100 can be adjusted to move to the second locking position to provide greater locking force to the latch 2000. This increases the compression of the sealing element 130, improving sealing performance and reducing wind noise, thus enhancing the user experience when the vehicle 100 is operating at high speed. When the vehicle 100's speed is less than the preset speed (i.e., when the vehicle 100 is at a relatively low speed or stationary), the target locking position can be the first locking position. In this case, the compression of the sealing element 130 can be relatively small, and the closing noise of the isolation component 120 can be relatively low, improving the user experience at the moment of closing. At the same time, adjusting the compression of the sealing element 130 to be relatively small is also beneficial to ensuring the service life of the sealing element 130.

[0199] Here, the embodiments of this application do not limit the specific value of the preset speed. In practical applications, those skilled in the art can determine it by combining relevant simulation experiments, etc. In specific practice, the preset speed may be a fixed value that has been preset at the factory of the vehicle 100 and cannot be adjusted by the user; or, although the preset speed has been preset at the factory of the vehicle 100, the user may flexibly adjust the preset speed based on their own physical sensations during actual use.

[0200] The locking tongue 1100 can be switched by rotation. The rotation angle of the locking tongue 1100 from the unlocked position to the first locked position is the first angle, and the rotation angle of the locking tongue 1100 from the unlocked position to the second locked position is the second angle. The second angle can be greater than the first angle in order to provide a greater locking force in the second locked position.

[0201] In some implementations, such as Figure 27 As shown, the feature information may include road condition information. Step S200 may further include: Step S220, when the road condition information indicates that the current road segment is a flooded road, determining the target locking position as a third locking position. The locking position includes a first locking position and a third locking position. The locking force between the latch and the latch in the first locking position is the first locking force, and the locking force between the latch and the latch in the third locking position is the third locking force. The third locking force is greater than the first locking force.

[0202] With this configuration, when the vehicle 100 is in a water-crossing condition, the locking tongue 1100 can be adjusted to move to the third locking position to provide a greater locking force to the latch 2000, thereby increasing the compression of the sealing element 130, improving the sealing performance, and improving the water-crossing performance of the vehicle 100.

[0203] The locking tongue 1100 can be switched by rotation. The rotation angle of the locking tongue 1100 from the unlocked position to the first locked position is the first angle, and the rotation angle of the locking tongue 1100 from the unlocked position to the third locked position is the third angle. The third angle can be greater than the first angle so as to provide a greater locking force in the third locked position.

[0204] It should be noted that in steps S210 and S220, the second locking position and the third locking position can be two different locking positions. In this case, the second angle and the third angle can be different. Alternatively, in steps S210 and S220, the second locking position and the third locking position can also be the same locking position. They are only distinguished because the scenarios are different. In this case, the second angle and the third angle can be the same.

[0205] In addition to the aforementioned speed and road condition information, the feature information can also include user-generated commands, such as voice input or key input, so that the user can flexibly adjust the locking position of the latch 1100 as needed.

[0206] Please refer to Figure 28 and Figure 29 , Figure 28 A schematic diagram of a locking control device; Figure 29 This is a schematic diagram of the structure of a defined module.

[0207] like Figure 28 As shown, this application embodiment also provides a locking control device 150, which is suitable for locking control of the locking module 140 involved in the aforementioned implementation methods. The locking control device 150 may be integrated into the controller and includes an acquisition module 151, a determination module 152, a first execution module 153 and a second execution module 154.

[0208] The acquisition module 151 can communicate with some sensors inside the vehicle 100 to acquire feature information, which includes at least one of speed information and road condition information. Here, this embodiment does not limit the types of sensors described above; in practical applications, those skilled in the art can determine the type based on the type of feature information. For example, when the feature information is speed information, the sensor can be a speed sensor. As another example, when the feature information is road condition information, the sensor can be a camera, radar, or other sensing elements capable of displaying the road conditions around the vehicle 100 in real time.

[0209] The determination module 152 and the acquisition module 151 are communicatively connected. The determination module 152 is used to receive feature information and determine the target lock position based on the feature information. The specific correspondence between the feature information and the target lock position is not limited here.

[0210] The first execution module 153 and the determining module 152 are communicatively connected. The first execution module 153 is used to receive target locking information and to control the movement of the locking tongue 1100 according to the target locking position, so as to drive the locking tongue 1100 to the target locking position.

[0211] The second execution module 154 and the determination module 152 are communicatively connected. The second execution module 154 is used to receive target locking information and to control the limit unit 1300 to switch to the limit state corresponding to the target locking position according to the target locking position, so that the locking tongue 1100 is limited by the limit unit 1300 at the target locking position.

[0212] With this configuration, during the use of the vehicle 100, the locking control device 150 can adjust the target locking position of the locking tongue 1100 through the first execution module 153 and adjust the limiting state of the limiting unit 1300 through the second execution module 154, so as to adjust the locking force between the locking tongue 1100 and the latch 2000, thereby adjusting the compression of the sealing element 130, which can meet different usage needs and better improve the user experience.

[0213] In some implementations, such as Figure 29 As shown, the determining module 152 may further include a first determining submodule 152A, which can be communicatively connected to the acquiring module 151. When the feature information is vehicle speed information, the first determining submodule 152A can determine the target locking position as the second locking position when the speed of the vehicle 100 is greater than or equal to a preset speed.

[0214] In some implementations, such as Figure 29 As shown, the determining module 152 may further include a second determining submodule 152B, which can be communicatively connected to the acquiring module 151. When the feature information is road condition information, the second determining submodule 152B can determine the target locking position as the third locking position if the road condition information indicates that the current road segment is a flooded road.

[0215] The aforementioned controller may include at least one processor, which is a circuit with signal processing capabilities. In one implementation, the processor may be a circuit with instruction read and execute capabilities, such as a central processing unit (CPU), a microprocessor unit (MPU), a graphics processing unit (GPU) (which can be understood as a type of microprocessor), or a digital signal processor (DSP). In another implementation, the processor can implement certain functions through the logical relationships of hardware circuits. These logical relationships of hardware circuits are fixed or reconfigurable. For example, the processor may be a hardware circuit implemented using an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as a field-programmable gate array (FPGA). In reconfigurable hardware circuits, the process of the processor loading a configuration document and configuring the hardware circuit can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units. Furthermore, the processor can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a neural network processing unit (NPU), tensor processing unit (TPU), deep learning processing unit (DPU), etc. Additionally, the controller may include memory for storing instructions, which some or all of the processor can call to implement corresponding functions. The controller can control the vehicle's functions based on inputs received from various subsystems (e.g., sensing systems). In some embodiments, the controller can be used to provide control over many aspects of the vehicle and its subsystems.

[0216] Specifically, in the embodiments of this application, the acquisition module 151, the determination module 152, the first execution module 153, and the second execution module 154 can each correspond to a processor; the first determination submodule 152A and the second determination submodule 152B can also each correspond to a processor. Alternatively, at least two of the acquisition module 151, the determination module 152, the first execution module 153, and the second execution module 154 can also correspond to a processor; for example, the acquisition module 151 and the determination module 152 can be integrated into a processor; for example, the first determination submodule 152A and the second determination submodule 152B can be integrated into a processor. In other words, in specific implementations, the number of modules integrated into each processor and the functions of the corresponding processors can be flexibly adjusted in the embodiments of this application.

[0217] This document uses specific examples to illustrate the principles and implementation methods of this application. The descriptions of the above embodiments are only for the purpose of helping to understand the methods and core ideas of this application. It should be noted that those skilled in the art can make several improvements and modifications to this application without departing from the principles of this application, and these improvements and modifications also fall within the protection scope of this application.
