[0031] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, 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. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0032] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0033] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0034] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this application is in use.

In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0035] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0036] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0037] like Figures 1 to 7 As shown, this application embodiment provides an integrated backrest lock with two unlocking methods and two warning signals, including a lock shell 1. The lock shell 1 is provided with a lock cylinder 2, a handle 3, a cable unlocking component 4, an electrical signal warning component 5, and a mechanical signal warning component 6. The handle 3 is throttle-connected to the lock cylinder 2, and the cable unlocking component 4, the electrical signal warning component 5, and the mechanical signal warning component 6 are all throttle-connected to the handle 3.

[0038] The integrated backrest lock design reduces the number of parts, has a high degree of integration, optimizes assembly efficiency, and improves adaptability.

[0039] When it is necessary to unlock the seat back, the handle 3 can be turned directly to unlock the lock cylinder 2, or the handle 3 can be turned indirectly to unlock the lock cylinder 2 by pulling the cable unlocking component 4. Users can choose the close-range pry-hand unlocking function or the remote cable unlocking function. The two unlocking methods increase the functionality and flexibility of the seat back lock. Different unlocking methods can meet the needs of different scenarios. For example, one unlocking method is used for normal daily opening, and the other unlocking method is used for quick opening in emergency situations.

[0040] When the lock cylinder 2 is in the unlocked state, the electrical signal warning component 5 and the mechanical signal warning component 6 will operate simultaneously. The electrical signal warning component 5 can transmit electrical signals and can be connected to the vehicle's dashboard or alarm system to provide electronic warnings, making it easy for users to remotely confirm the locking status. The mechanical signal warning component 6 can provide intuitive visual prompts to ensure that users can clearly perceive the locking status. It is simple and reliable. The two warning signals can remind users of the changes in the lock status from different angles, improving the safety and convenience of use.

[0041] like Figures 1 to 7 As shown, in this embodiment, the cable-type unlocking component 4 includes an unlocking cable 41 and a handle 42. The unlocking cable 41 passes through the lock housing 1 and is connected to the handle 3. The handle 42 is connected to the handle 3 through the unlocking cable 41.

[0042] When in use, pulling the handle 42 causes the lever 3 to rotate via the unlocking cable 41, which in turn causes the lock cylinder 2 to unlock. This design allows the unlocking operation to be completed outside the lock housing 1 via the handle 42. Users can operate the handle 42 to unlock from different locations (such as the side of the trunk), improving convenience. This external handle 42 unlocking method is especially practical in situations where space is narrow or operation is inconvenient. One end of the unlocking cable 41 is connected to the lever 3, and the other end is connected to the handle 42.

[0043] like Figures 1 to 7 As shown, in this embodiment, the electrical signal warning component 5 includes a micro switch 51, which is fixedly installed inside the lock housing 1, and the handle 3 can press the micro switch 51.

[0044] When in use, as the handle 3 rotates to unlock the lock cylinder 2, the handle 3 simultaneously presses the micro switch 51 to transmit an electrical signal. When the backrest is locked, the handle 3 resets and separates from the micro switch 51, cutting off the electrical signal and thus providing real-time feedback on the locking status. The micro switch 51 can be linked with the vehicle's electronic system to provide audible and visual alarms or dashboard prompts, enhancing safety. Moreover, the micro switch 51 responds quickly, ensuring immediate feedback on status changes.

[0045] like Figures 1 to 7 As shown, in this embodiment, the mechanical signal warning component 6 includes a warning plate 61, which is disposed inside the lock housing 1. The handle 3 can drive the warning plate 61 to extend or retract into the lock housing 1.

[0046] When in use, as the handle 3 rotates to unlock the lock cylinder 2, the handle 3 simultaneously causes the warning plate 61 to extend out of the lock housing 1. When the backrest is locked, the handle 3 returns to its original position, and the handle 3 will cause the warning plate 61 to retract into the lock housing 1 and hide. Users can directly judge the locking status by the position of the warning plate 61 without relying on electronic devices. The extension or retraction of the warning plate 61 is simple and reliable, and can provide effective warning information in various environments, enhancing the visibility, operability, and security of the backrest lock. The warning plate 61 can be made of bright and eye-catching colors such as red, making it easy for users to quickly and clearly perceive the locking status.

[0047] like Figures 1 to 7 As shown, in this embodiment, a warning insert 62 is provided on the top of the warning plate 61. When in use, the warning insert 62 will be more prominently displayed on the outside of the lock case 1, further enhancing the warning effect. The color of the warning insert 62 can be set to be the same as the color of the lock case 1 and the handle 3, so that only the warning insert 62 can be seen when locked, and the red warning plate 61 can be seen when unlocked, so that the two different states of unlocking and locking can be seen intuitively. The warning insert 62 can also be made of reflective material or fluorescent coating to improve the warning effect and enhance visibility in night or low light environments.

[0048] like Figures 1 to 7 As shown, in this embodiment, a torsion spring 31 is installed on the handle 3; the torsion spring 31 provides the handle 3 with a restoring force, ensuring that the handle 3 automatically returns to its original position when no external force is applied, thus keeping the lock cylinder 2 stable.

[0049] like Figures 1 to 7 As shown, in this embodiment, a compression spring 63 is installed on the warning plate 61. The installation of the compression spring 63 ensures the smoothness and accuracy of the movement of the warning plate 61. It can ensure that the warning plate 61 moves smoothly during the extension and retraction process, and at the same time prevent the warning plate 61 from loosening in the lock housing 1, thereby improving the reliability and service life of the mechanical signal warning component 6.

[0050] like Figures 1 to 7 As shown, in this embodiment, a locking interface 11 is provided through the lock housing 1. The unlocking cable 41 passes through the locking interface 11 and engages with it. The locking interface 11 restricts the displacement of the cable, prevents the cable from loosening, ensures the connection stability between the cable and the handle 3, and ensures that the unlocking cable 41 can effectively transmit the pulling force to drive the handle 3 to achieve the unlocking function, thereby improving the reliability of the transmission.

[0051] like Figures 1 to 7 As shown, in this embodiment, a switch bracket 12 is fixedly installed inside the lock housing 1, and a micro switch 51 is installed on the switch bracket 12. The switch bracket 12 fixes the position of the micro switch 51, ensuring that the action of the handle 3 accurately triggers the micro switch 51 to turn on and off, avoiding mis-triggering or failure caused by the micro switch 51 shifting, and improving the reliability and sensitivity of the electrical signal warning component 5.

[0052] Working principle: The integrated backrest lock provided in this application has two unlocking methods and two warning signals. When it is necessary to unlock the seat back, the handle 3 can be turned directly to unlock the lock cylinder 2, or the handle 42 can be pulled. The handle 42 drives the handle 3 to rotate through the unlocking cable 41, and the handle 3 indirectly drives the lock cylinder 2 to unlock. Users can choose the close-range prying unlocking function or the remote cable unlocking function.

[0053] When the handle 3 rotates to unlock the lock cylinder 2, the handle 3 simultaneously presses the micro switch 51 to transmit an electrical signal. This signal can be connected to the vehicle's dashboard or alarm system to provide electronic warnings and provide real-time feedback on the locking status. This allows users to remotely confirm the locking status. In addition, the handle 3 simultaneously causes the warning plate 61 to extend out of the lock housing 1, providing an intuitive visual prompt and ensuring that users can clearly perceive the locking status. This is simple and reliable.

[0054] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
