[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] Please refer to the attached document. Figures 1-3 The embodiments of this application provide a locking system for a trunk lid, which is suitable for locking a trunk lid 4 on a vehicle. The trunk lid 4 is hinged and installed in the trunk or other storage compartment of the vehicle body (such as the storage compartment in the front engine compartment), dividing the space inside the compartment into a bottom hidden space and a storage space for placing luggage and other items. The trunk lid 4 is used to cover the bottom hidden space and form the bottom plate of the storage space.

[0026] The locking system includes a lock and a control assembly. The lock includes a latch 1 and a locking mechanism. The locking mechanism includes a lock seat 3 and an actuator 2. The control assembly includes a command component and a controller. The latch 1 and the locking mechanism are respectively installed on the trunk lid 4 and the vehicle body. The latch 1 has a lock hole. The lock seat 3 has a lock groove for inserting the latch 1 and a guide hole located on one side of the lock groove and communicating with the lock groove. The actuator 2 has a locking rod 21 for inserting into the latch 1 to achieve locking, and a power component that drives the locking rod 21 to move into or out of the latch 1. The power component can be a cylinder or a motor, etc. The actuator 2 is located on one side of the lock seat 3. The locking rod 21 can be inserted into the latch 1 located in the lock groove through the guide hole to achieve locking by passing through the interlock seat 3 and the latch 1.

[0027] The locking lever 21 can be located within the guide hole. When the trunk lid 4 is closed, the latch 1 will be inserted into the lock groove in the lock seat 3, with the lock hole aligned with the guide hole. When it is necessary to lock the trunk lid 4, the power component of the actuator 2 pushes the locking lever 21, causing the locking lever 21 located within the guide hole to extend forward and insert into the latch 1 located in the lock groove. In this way, the trunk lid 4 is locked in the closed position.

[0028] The instruction components include independently configured unlocking components with dedicated information (such as dedicated remote control switches with specific remote control signals), and / or components capable of inputting instruction information (such as information components used to collect or receive unlocking-specific authorization information, unlocking instructions, locking instructions, etc.), and instruction information capable of sending unlocking-specific authorization information, unlocking instructions, and locking instructions to the controller.

[0029] The controller is electrically connected to the actuator 2 and the command unit. It has an unlocking start module for verifying the unlocking authorization information, an information processing module, etc., and is used to control the displacement of the locking rod 21 of the actuator 2 to unlock or lock according to the unlocking or locking command after verifying the unlocking authorization information: according to the unlocking command, the actuator 2 is controlled to drive the locking rod 21 away from the latch 1; according to the locking command, the actuator 2 is controlled to drive the locking rod 21 to insert into the latch 1.

[0030] With this configuration, the luggage compartment lid locking system provided in this application not only locks the luggage compartment lid 4, but also limits unlocking permissions: after the luggage compartment lid 4 is locked, it can only be unlocked by a component with unlocking permission information or a component that requires the input of unlocking permission information before the unlocking command can be entered, thus achieving unlocking protection; unauthorized users cannot open the luggage compartment lid 4, thereby effectively protecting the components of the control system located below the luggage compartment lid 4 from vandalism and avoiding situations that affect driving safety, such as accidental damage or human interference.

[0031] The trunk lid locking system provided in this application is very suitable for highly intelligent vehicles. It is also very suitable for placing components that are not suitable for the driver or passengers to touch under the trunk lid 4, such as components of the vehicle's central control unit, information collector, and other control systems that are maintained by after-sales maintenance personnel or the manufacturer. It is also very suitable for the application scenarios of car rental, improving the protection and security of vehicle information.

[0032] Specifically, the instruction components include any one or any combination of an operation control panel, a voice collector, a fingerprint collector, and a remote control switch.

[0033] For example, in a preferred embodiment, the instruction component includes an operation control screen, which is the vehicle's central control screen, and the controller is the vehicle's central control host connected to the central control screen. This eliminates the need for additional switches that need to be detached from the vehicle body, thus avoiding the risk of loss. When unlocking is required (e.g., when the host needs maintenance or repair), simply logging into an account with operating permissions, entering unlocking verification information, or enabling unlocking permissions by activating the central control host's debugging mode will allow the controller to obtain dedicated unlocking permission information. Then, an unlocking command can be entered on the central control screen to unlock the vehicle.

[0034] When a voice acquisition device is set up, specific voice information for verifying unlocking permissions can be pre-stored in the controller as dedicated unlocking permission information; when the acquired voice command is combined with the pre-stored specific voice information, the verification is successful, and then the unlocking voice command can be entered.

[0035] When a fingerprint scanner is installed, the corresponding unlocking fingerprint is pre-stored in the controller as dedicated unlocking permission information. When the input fingerprint matches the pre-stored fingerprint, the verification is successful and the lock can be opened.

[0036] like Figure 1 As shown, both the latch 1 and the locking mechanism are located in the hidden space at the bottom of the trunk lid 4, which is enclosed by the trunk. In this way, the lock is concealed and not exposed, which is not only aesthetically pleasing but also avoids occupying external space and prevents damage.

[0037] Actuator 2 and lock seat 3 can be installed on the sill beam 5 of the trunk, specifically on the inner side of the sill beam 5. Lock 1 is installed on the trunk lid 4, located on the inner side of the lid facing the bottom wall of the trunk. After the trunk lid 4 is closed onto the sill beam 5, lock 1 is precisely inserted into the lock groove, and the lock hole aligns with the guide hole on the lock seat 3. Actuator 2 is installed on one side of the lock seat 3. In its original state, the locking rod 21 is inserted into the guide hole on the lock seat 3. When the controller receives a locking command, it can drive the locking rod 21 to insert into lock 1 to achieve locking.

[0038] In some embodiments, the control component is further provided with a first sensor for detecting that the trunk lid 4 has been opened, and the first sensor is electrically connected to the controller. In this way, the controller can receive information in a timely manner when the trunk lid 4 is accidentally opened, and promptly send an alarm or information to the relevant personnel in the background, such as the manager of the rental car.

[0039] Specifically, in some embodiments, the first sensor is a pressure sensor and is located on the area of ​​the sill beam 5 that supports the trunk lid 4. When the trunk lid 4 is opened, the pressure sensor senses the pressure change and can promptly send a signal to the controller.

[0040] In some embodiments, the locking mechanism or control component further includes a second sensor, which is mounted on the lock seat 3 and used to sense whether the latch 1 is inserted into the lock slot. The controller activates the actuator 2 to lock based on the signal from the second sensor. Thus, when the trunk lid 4 is closed, the second sensor generates a sensing signal, which forms a locking command. The controller directly activates the actuator 2 based on the signal from the second sensor to insert the locking lever 21 into the latch 1 located in the lock seat 3 to complete the locking. This eliminates the need for the operator to generate a command at the central control screen in the driver's seat, simplifying the operation.

[0041] The second sensor can be a pressure sensor and is set on the bottom wall of the lock groove or on the lock seat 3 in the area where it abuts against the latch 1, such as the abutting plane described below; the second sensor can also be a photoelectric sensor and is set on the side wall of the lock groove. When the latch 1 is inserted, the light emitted by it is triggered and sensed.

[0042] To ensure the alignment of the latch 1 and the guide hole, in some embodiments, such as Figure 1 As shown, the lock base 3 can be block-shaped with a recessed lock groove. The lock base 3 has abutment surfaces arranged on both sides of the lock groove opening. The latch 1 includes a locking plate with a lock hole and outer wing plates located on both sides of the locking plate. Both the locking plate and the locking plate body are plate-shaped, and the outer wing plates are used to abut against the abutment surfaces. This arrangement allows the locking plate to connect smoothly to the luggage compartment lid 4 and to flatly abut against the lock base 3, thus providing a positioning function and aligning the lock hole with the guide hole on the lock groove. This ensures that the locking rod 21 on the actuator 2 can be accurately inserted into the lock hole on the latch 1.

[0043] In some embodiments, the width of the locking groove can gradually decrease along the direction from the opening to the bottom of the groove, that is, the locking groove is V-shaped or V-shaped, which facilitates the insertion of the locking plate of the latch 1 into the locking groove and can accurately limit the insertion depth to ensure that the lock hole and the guide hole are aligned.

[0044] To ensure a tight fit between the locking rod 21 and the latch 1, in some embodiments, the locking rod 21 has a frustum section. The diameter of the frustum section gradually decreases along the axial direction near the lock groove, and it has a locking section that matches the size of the lock hole of the latch 1. This allows for quick insertion of the locking rod 21 into the latch 1, and stops displacement when the locking section of the frustum section is inserted into the lock hole and tightly fitted with it. This ensures that the locking rod 21 is tightly inserted into the lock hole on the latch 1, with no large gap between them. This prevents excessive gaps between the locking rod 21 and the lock hole from causing vibration and noise during vehicle operation.

[0045] In some embodiments, the outer surface of the locking rod 21 is embedded with elastic balls. These elastic balls are spring-loaded onto the locking rod 21 and can roll and move elastically along the axial direction of the locking rod 21. When the locking rod 21 is inserted into the latch 1, the elastic balls are compressed by the latch 1 until they are fully embedded in the locking rod 21, allowing the section with the embedded elastic balls to pass through the lock hole. After passing through, the elastic balls return to their original position and partially protrude from the surface of the locking rod 21, thus providing a certain degree of anti-disengagement effect on the latch 1 and enhancing the tight connection between the locking rod 21 and the lock hole.

[0046] In some embodiments, a backup remote control switch electrically connected to the actuator 2 may also be provided. When the vehicle is deformed due to a collision or the central control screen becomes unusable for other reasons, the backup remote control switch can be used to send an unlocking command to open the trunk lid 4 to maintain the central control unit or retrieve information from the central control unit.

[0047] Embodiments of this application also provide a vehicle, including a vehicle body and a locking system for the trunk lid as described in any of the above embodiments. This vehicle possesses the aforementioned protective and security features that effectively prevent the trunk lid 4 from being opened arbitrarily, which will not be elaborated further here.
