Description

Technical Field

[0001] This application relates to the field of automotive body doors and door locks, specifically to an automotive vehicle. Background Technology

[0002] Current car tailgates typically employ various opening methods, including single-door, double-door, side-opening, and hatchback tailgates. Double-door tailgates, with their wider opening and convenient access to items, are widely used. A double-door tailgate usually consists of two door panels connected by side hinges, and features a main lock and a secondary lock. The main lock connects and locks the left and right tailgates. To ensure the main lock remains engaged with the vehicle while it is in motion, a secondary lock is installed to assist in locking the tailgate. The combined action of the main and secondary locks achieves the locking of the tailgate to the vehicle body. However, current vehicle tailgate secondary locks use a latch-type structure, where the latch engages with the latch via a pawl along the vehicle's direction of travel. This latch occupies a significant amount of space in the trunk, protrudes, and poses a risk of head injury. Furthermore, the secondary lock's complex structure, large size, and high unlocking force result in a less intuitive operation. Utility Model Content

Detailed Implementation

[0040] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0041] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0042] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0043] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0044] The existing automotive configuration's advantage in opening the tailgate lies in providing users with good passage convenience and quick loading and unloading of items. However, the existing tailgate's secondary lock structure has problems such as head bumping when passing through and difficulty in unlocking. In order to improve the concealment of the vehicle's secondary lock installation and the ease of unlocking, this application provides an automotive 100. Figure 1 This is a schematic diagram of the structure of a car provided in an embodiment of this application. Figure 2 This is a structural diagram of a tailgate auxiliary lock structure for an automobile provided in an embodiment of this application, as shown below. Figure 1 and Figure 2 As shown, the vehicle 100 includes a tailgate 10 and a roof 20. The tailgate 10 is provided with a door handle 11. The vehicle 100 also includes a tailgate auxiliary lock structure 30, which includes a latch 31, a lock body assembly 32, and a linkage assembly 33. The latch 31 is installed on the roof 20, and the vertical projection of the latch 31 on the roof 20 is located inside the outer edge of the roof 20.

[0045] The lock body assembly 32 includes a lock body bracket 321 and a bolt 322 movably installed in the lock body bracket 321. The bolt 322 can be engaged in the latch 31. The door handle 11 is connected to the bolt 322 through the linkage assembly 33, driving the bolt 322 to move until it is unlocked.

[0046] In this application, the latch 31 is concealed within the outer edge of the roof 20, preventing it from protruding from the roof 20 of the vehicle 100. This structure eliminates the risk of head injury caused by the latch 31 protruding when a person passes through the tailgate 10 or retrieves goods. Simultaneously, the door handle 11 drives the linkage component 33, which in turn drives the latch 322 to move vertically out of the latch 31, thus unlocking the vehicle. This reduces the movement space of the latch 322 and simplifies the locking structure, significantly reducing the risk of head injury caused by the protruding latch 31 in existing vehicles. The tailgate secondary lock structure of this application is simple and effortless to operate, and convenient for repeated use.

[0047] To make the technical solution, purpose, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. Furthermore, for ease of understanding, the vehicle 100 is used as a reference frame for direction. The vehicle 100 is horizontally positioned on the ground, with the direction extending towards the front of the vehicle defined as forward, and vice versa. The direction perpendicular to the horizontal and away from the ground is defined as upward, and vice versa. Standing at the rear of the vehicle and facing it, the left hand direction is defined as the left side, and the right hand direction as the right side.

[0048] The rear box of the car 100 in this application (not shown) is a square frame structure, with side panels covering the left and right sides of the rear box (not shown), and a canopy 20 on the top of the rear box (not shown).

[0049] Figure 3 This is a cross-sectional schematic diagram of a tailgate auxiliary lock structure for an automobile, provided in an embodiment of this application. Figure 4 This is a partial structural diagram of a tailgate auxiliary lock structure for an automobile, provided in an embodiment of this application. Figure 3 and Figure 4 As shown, the ceiling 20 is a double-layered panel structure with spaced intervals. The ceiling 20 includes a ceiling body 22 and a ceiling trim 23 located above the ceiling body 22. The ceiling body 22 is provided with an avoidance notch 221. The latch 31 passes through the avoidance notch 221 and is installed on the lower surface of the ceiling trim 23. The latch 31 is accommodated between the ceiling body 22 and the ceiling trim 23.

[0050] The rear end of the rear box (not shown) is equipped with a double-opening tailgate 10. The tailgate 10 includes an inner panel 12, an outer panel 13 and a top panel 15. The top panel 15 is provided with a lock tongue through hole 151. The lock body bracket 321 is installed on the inner panel 12 near the top panel 15.

[0051] Specifically, in combination Figure 1As shown, the tailgate 10 includes a left door 16 and a right door 17, and the tailgate 10 has a square frame structure. The front of the tailgate 10 is an inner panel 12, the rear of the tailgate 10 is an outer panel 13, and the top of the tailgate 10 is provided with a top panel 15. That is, the tailgate 10 is a hollow door structure formed by the inner panel 12, the outer panel 13, and the top panel 15 sandwiched between them.

[0052] In order to maintain the neatness of the appearance of the tailgate 10 and improve its aesthetics, the lock body bracket 321 is installed between the inner panel 12 and the outer panel 13 of the left door 16 and fixed to the inner panel 12, so that the lock body bracket 321 is hidden inside the left door 16.

[0053] The tailgate 10 is equipped with an opening handle 11, a main tailgate lock structure (not shown), and a secondary tailgate lock structure 30. The main tailgate lock structure (not shown) is used to lock the closed tailgate 10 with a key; it cannot be unlocked without a key and is used infrequently. The secondary tailgate lock structure 30, however, is the tailgate lock used frequently in daily life. Whether people are getting in or out of the tailgate 10, or when items need to be accessed, simply pulling the opening handle 11 unlocks and opens the tailgate 10, and simply pushing the tailgate 10 closes automatically locks the secondary tailgate lock structure 30. Therefore, the secondary tailgate lock structure 30 is convenient to use and is used more frequently.

[0054] In this application, the tailgate 10 of the automobile is formed by cold rolling and stamping. In other embodiments, metal alloys, engineering plastics or other materials can be used for forming by sheet metal methods, die casting methods, vacuum forming methods or injection molding methods, etc., and no limitation is made here.

[0055] In the above solution, the tailgate 10 of the car adopts a double-layer structure that can accommodate the installation of the lock and the installation of the door handle 11. This structure can improve the strength of the tailgate 10 and also improve the neatness and aesthetics of the tailgate 10.

[0056] Figure 5 This is a schematic diagram of the structure of a car latch provided in an embodiment of this application, as shown below. Figure 5 As shown, the latch 31 includes a latch bracket 311, the latch bracket 311 has an insertion hole 3111 in the middle, the latch tongue 322 can be locked in the insertion hole 3111, and the latch bracket 311 has first mounting holes 3112 at both ends.

[0057] Specifically, the main body of the latch bracket 311 is a groove-shaped part in the middle. Two edges from the opening of the groove-shaped structure protrude away from the center of the latch bracket 311 to form the left and right fixing parts of the latch bracket 311. Furthermore, a limiting stop 3113 protrudes from the bottom of the groove-shaped structure towards the front of the vehicle and bends to form the latch bracket 3111. The limiting stop 3113 is used to prevent the latch bracket 311 from shifting after installation. The insertion hole 3111 is a square hole located in the middle of the groove-shaped structure and adjacent to the limiting stop 3113. The left and right fixing parts each have a through first mounting hole 3112 for installing bolts to fix the latch bracket 311 to the inner panel 12 of the left side door 16.

[0058] Please continue reading. Figure 4 The latch 31 is installed on the lower surface of the ceiling panel 22, and the vertical projection of the latch 31 on the ceiling body 21 is located within the outer edge of the ceiling body 21. Understandably, the latch 31 is installed within the clearance opening 211 of the ceiling 21 and does not protrude from the lower edge of the ceiling body 21. The latch 31 is concealed between the ceiling body 21 and the ceiling panel 22 to facilitate passage of people and access to goods without causing scratches or collisions.

[0059] The latch 31 of this application can be formed by cold rolling and stamping. In other embodiments, it can be formed by machining, die casting or other methods using metal alloys or other materials, and no limitation is made here. The latch 31 has a simple structure and occupies little space. The latch 31 is installed below the outer edge of the canopy 20, which facilitates the passage of people and the retrieval of goods.

[0060] In this application, the latch 31 is installed on the roof 20 of the vehicle 100, and the roof 20 has a relatively neat appearance. In order to maintain the neatness of the appearance of the tailgate 10 and improve its aesthetics, the lock body assembly 32 is installed on the tailgate 10, that is, the lock body assembly 32 is installed between the inner panel 12 and the outer panel 13 of the left door 16 and fixed to the inner panel 12, so that the lock body bracket 321 is concealed inside the left door 16.

[0061] In some embodiments, the lock body assembly 32 includes a lock body bracket 321 and a bolt 322 movably mounted within the lock body bracket 321, the bolt 322 being able to engage within the latch 31. It is understood that the lock body assembly 32 is the main component of the tailgate auxiliary lock structure 30 of this application.

[0062] Figure 6 Please refer to the schematic diagram of a car lock body assembly provided in this application embodiment. Figure 4 and Figure 6The lock body bracket 321 is vertically fixed to the inner panel 12 of the left door 16 in the vertical direction and is concealed inside the left door 16. The lock body bracket 321 includes a bottom plate 3211, an upper bracket 3212 and a lower bracket 3213 connected to each other. The bottom plate 3211 is installed on the top plate 15 of the tailgate 10. The upper bracket 3212 is connected to the bottom plate 3211 and extends towards the bottom of the car. The lower bracket 3213 is connected to the end of the upper bracket 3212 away from the bottom plate 3211.

[0063] Please continue reading. Figure 6 Specifically, the base plate 3211 has a sheet-like structure. The base plate 3211 has second mounting holes 32111 at both ends. Both second mounting holes 32111 are round holes that penetrate the base plate 3211. A through hole 32112 is provided between the two second mounting holes 32111. The through hole 32112 is a square hole that penetrates the base plate 3211 to facilitate the installation of related components of the locking tongue 322.

[0064] To simplify the structure of the lock body bracket 321 and reduce its volume and weight, the upper bracket 3212 and the lower bracket 3213 are U-shaped structures, and the base plate 3211, the upper bracket 3212 and the lower bracket 3213 are connected in sequence. The U-shaped structure is used to accommodate at least part of the lock tongue 322.

[0065] Specifically, the projections of the upper bracket 3212 and the lower bracket 3213 in the front-to-back direction are both U-shaped frame structures, with the length of the upper bracket 3212 being greater than the length of the lower bracket 3213. The projection of the lower bracket 3213 in the left-to-right direction is bent, meaning that the bottom plate 3211 of the lock body is fixed to the top plate 15 of the left door 16. The distance between the upper bracket 3212 and the surface of the inner plate 12 is less than the distance between the lower bracket 3213 and the inner plate 12, meaning that the lower bracket 3213 protrudes towards the rear of the vehicle. With this structure, the portion of the lock body bracket 321 below the lower bracket 3213 is located between the inner plate 12 and the outer plate 13 and will not rub against either the inner plate 12 or the outer plate 13.

[0066] The open end of the U-shaped frame of the upper support 3212 is connected to the bottom of the base plate 3211, and the open end of the U-shaped frame of the lower support 3213 is connected to the bottom of the U-shaped frame of the upper support 3212. Thus, the base plate 3211, upper support 3212, and lower support 3213 are sequentially connected from top to bottom to form a double-U combined frame structure. A first receiving area 3215, which is rectangular, is formed between the base plate 3211 and the upper support 3212. A second receiving area 3216, also rectangular, is formed between the upper support 3212 and the lower support 3213. In order to connect the two first receiving areas 3215 and the second receiving area 3216 so as to facilitate the installation of the locking tongue 322 and related components, a first through hole 3217 is provided between the upper bracket 3212 and the lower bracket 3213 for the locking tongue 322 to be installed, and a second through hole 3218 is provided at the bottom of the lower bracket 3213 for the installation of related linkage components 33.

[0067] The base plate 3211, upper support 3212 and lower support 3213 in this application can be formed by cold rolling and stamping. In other embodiments, they can be formed by machining, die casting or other methods using metal alloys or other materials. The connection between the base plate 3211, upper support 3212 and lower support 3213 can be made by spot welding, laser welding or other connection methods, and there are no restrictions here.

[0068] In the above solution, the base plate 3211, the upper bracket 3212 and the lower bracket 3213 have a simple and lightweight structure, and are located in the middle of the inner panel 12 and the outer panel 13 of the left door 16, which is convenient for installation and maintenance and has a high cost performance.

[0069] In this application, the lock body bracket 321 is a fixed component vertically installed inside the left side door 16, while the lock tongue 322 is a movable component installed in the first receiving area 3215 and the second receiving area 3216, capable of vertical movement. The two components, one movable and one stationary, together form the lock body assembly 32. When the tailgate 10 is closed, the lock tongue 322 automatically inserts into the latch 31, and the lock tongue 322 moves vertically.

[0070] In some implementations, such as Figure 6 As shown, the locking tongue 322 includes a pin 3221, a return spring 3222, and a connector 32211 extending from the pin 3221. The connector passes through the first through hole and is received in the second receiving area. The connector is used to connect the linkage component.

[0071] Specifically, the pin 3221 is a long and narrow structure that is larger at the top and smaller at the bottom. The upper end of the pin 3221 is a wedge-shaped locking tongue 322. The pin extends downward from the upper part of the pin 3221 and tapers to form a connector 32211. The end of the connector 32211 away from the pin 3221 is provided with a third mounting hole 32212. The third mounting hole 32212 is an oblong hole structure and can be connected to the related linkage component 33.

[0072] In some implementations, please refer to [the relevant documentation]. Figure 6 The reset spring 3222 is installed in the first receiving area 3215, and the end of the reset spring 3222 away from the pin 3221 abuts against the side wall of the upper bracket 3212. The reset spring 3222 drives the pin 3221 to move vertically to reset.

[0073] Specifically, the return spring 3222 is a compression spring. The return spring 3222 is installed in the first receiving area 3215, and the pin 3221 passes through the first through hole 3217 into the first receiving area 3215. In this structure, the return spring 3222 and the connector 32211 at the lower end of the pin 3221 are in a sliding fit, allowing the pin 3221, along with the connector 32211, to move up and down within the first receiving area 3215. Simultaneously, the connector 32211 can continue downwards through the first through hole 3217 to the second receiving area 3216, facilitating connection of the connector 32211 to the associated linkage component 33 via the third mounting hole 32212.

[0074] Because the first receiving area 3215 is equipped with a return spring 3222, when the tailgate 10 is closed, the compressed return spring 3222 can rebound and push the pin 3221 to move upward, and then the latch 322 automatically inserts into the insertion hole 3111 of the latch 31, and the latch 322 is in a vertical movement state.

[0075] The pin 3221 and the connector 32211 extending from the pin 3221 in this application are formed by cold rolling and stamping. In other embodiments, they can also be formed by machining, die casting or other methods using metal alloys or other materials, and no limitation is made here.

[0076] In the above solution, the combination of the pin 3221 and the return spring 3222 enables the locking tongue 322 to have elasticity and mobility. Its structure is simple and lightweight, requires little installation space, and has a good cost performance.

[0077] The lock body assembly 32 and the linkage assembly 33 are connected to form a linkage combination mechanism. That is, pulling the door handle 11 is connected to the bolt 322 through the linkage assembly 33, which drives the bolt 322 to move vertically until it is unlocked. Therefore, the linkage assembly 33 is the intermediate transmission component of this application, which has the function of transmitting driving force and changing the direction of driving force.

[0078] Figure 7 Please refer to the schematic diagram of a linkage component for an automobile provided in this application embodiment. Figure 1 and Figure 7 In order to maintain the neatness and aesthetics of the car tailgate 10, the linkage component 33 is installed on the car tailgate 10. That is, the linkage component 33 is installed between the inner panel 12 and the outer panel 13 of the left door 16 and fixed on the inner panel 12, so that the linkage component 33 is hidden inside the left door 16.

[0079] To reduce the thickness of the linkage assembly 33 in the front-to-back direction and simplify the linkage structure, the linkage assembly 33 includes a connected swing arm 331, a bracket 332, a first pull cable 333 and a second pull cable 335 connected to the swing arm 331; the first pull cable 333 is connected to the door handle 11, and the second pull cable 335 is connected to the latch 322; moreover, the first pull cable 333 has a connecting cable head 336 at one end near the linkage assembly 33; both ends of the second pull cable 335 have connecting cable heads 336. The third mounting hole 32212 of the pin 3221 is connected to the connecting cable head 336.

[0080] Specifically, such as Figure 2 As shown, the linkage component 33 is similar to a lever structure connected between two cables. The swing arm 331 acts as the lever, and the bracket 332 acts as the fulcrum. The first cable 333 connects to the power arm of the adjacent swing arm 331 and drives the swing arm 331. Under the driving force, the swing arm 331 swings around the fulcrum. Understandably, when the tailgate 10 is opened, pulling the door handle 11 causes the first cable 333 to pull the swing arm 331. The swing arm 331 then drives the second cable 335 and pulls the latch 322 vertically out of the latch 31.

[0081] For details, please continue reading Figure 7The swing arm 331 is a long, strip-shaped structure with a first hole 3311, a second hole 3312, and a third hole 3313 on its surface. The first hole 3311 and the third hole 3313 are located at both ends of the swing arm 331 and are used to connect the first cable 333 and the second cable 335, respectively. The second hole 3312 is located between the first hole 3311 and the third hole 3313, and the distance from the first hole 3311 to the second hole 3312 is greater than the distance from the third hole 3313 to the second hole 3312. Understandably, the length of the power arm of the swing arm 331 is greater than the resistance arm, which can reduce driving resistance.

[0082] In the above scheme, the lever arm 331 has a relatively simple structure, and by setting three holes, the direction of the driving force can be changed, and the locking tongue 322 can be driven with a smaller force. It has low manufacturing cost, small space occupation, and is conducive to installation and maintenance.

[0083] For details, please continue reading Figure 7 The bracket 332 has an arch bridge-shaped structure. A hole is provided in the middle of the protrusion of the bracket 332 for connecting the fulcrum of the swing arm 331, namely the second hole 3312. A fourth mounting hole 3321 is provided on the straight part formed by the extension of the arch bridge structure at both ends of the bracket 332. The fourth mounting hole 3321 is used to install bolts to fix the bracket 332, that is, to fix the fulcrum formed by the swing arm 331 and the bracket 332.

[0084] In the above scheme, the lever principle-based swing arm 331 and bracket 332 have a relatively simple structure. Moreover, the swing arm 331 changes the direction of the driving force, and a smaller force can be used to drive the locking tongue 322. It has low manufacturing cost, small space occupation, and is conducive to installation and maintenance.

[0085] Specifically, please refer to the following: Figure 6 and Figure 7 The main body of the first cable 333 is a steel wire rope. One end of the first cable 333 is connected to the door handle 11, and the other end of the first cable 333 is provided with a connecting cable head 336 and connected to the first hole 3311 of the swing arm 331. The main body of the second cable 335 is a steel wire rope. Both ends of the second cable 335 are provided with connecting cable heads 336. One end of the second cable 335 is connected to the third hole 3313 of the swing arm 331, and the other end of the second cable 335 passes through the second through hole 3218 and is connected to the third mounting hole 32212 of the pin 3221. Thus, the first cable 333 and the second cable 335 connect the door handle 11 at the front end, the linkage component 33 in the middle and the locking tongue 322 at the rear end into a whole linkage mechanism combination.

[0086] Figure 8 This is a schematic diagram of the structure of a car connector cable head provided in an embodiment of this application, as shown below. Figure 8As shown, in order to achieve quick connection between the first cable 333, the second cable 335 and related components, the connecting cable head 336 in this application is provided with a buckle 3361. The connecting cable head 336 of the first cable 333 is connected to the swing arm 331 through the buckle 3361. The connecting cable head 336 at one end of the second cable 335 is connected to the swing arm 331 through the buckle 3361. The connecting cable head 336 at the other end of the second cable 335 is connected to the locking tongue 332 through the buckle 3361, thereby realizing the convenience of connecting the first cable 333, the second cable 335 and related components and the speed of installation.

[0087] Specifically, the connecting cable head 336 includes a main body bent snap-fit ​​portion 3362 and an anti-detachment portion 3363 extending from the snap-fit ​​portion 3362. The snap-fit ​​portion 3362 has a 90° bent structure, and the end of the snap-fit ​​portion 3362 is provided with a connecting hole 33621. One end of the first cable 333 and the second cable 335 are inserted into the connecting hole 33621 and snapped tightly. The anti-detachment portion 3363 extends from a direction away from the connecting hole 33621 and in a direction parallel to the connecting hole 33621.

[0088] Specifically, Figure 9 This is a schematic diagram of the structure of a car clip provided in an embodiment of this application, such as... Figure 9 As shown, the buckle 3361 includes a limiting part 33611 and an insertion part 33612 extending from the limiting part 33611. Both the limiting part 33611 and the insertion part 33612 are circular structures with a third through hole 33613 at the center. The diameter of the limiting part 33611 is larger than that of the insertion part 33612. The top end of the insertion part 33612 is conical, and the top end face of the insertion part 33612 radiates radially and extends towards the limiting part 33611 to form at least two slits, making the insertion part 33612 of the buckle 3361 elastic. The third through hole 33613 of the buckle 3361 can be engaged with the anti-detachment part 3363 of the connecting cable head 336. Understandably, when the connecting cable head 336 at one end of the first cable 333 is connected to the first hole 3311 of the swing arm 331, and the connecting cable heads 336 at both ends of the second cable 335 are connected to the third hole 3313 of the swing arm 331 and the third mounting hole 32212 of the pin 3221 respectively, a buckle 3361 is installed at the connection point and locked in the anti-detachment part 3363 of the connecting cable head 336, so that the connection is tighter and more secure.

[0089] In the above scheme, the arrangement of the first cable 333 and the second cable 335 reduces the size of the linkage component 33, and the transmission structure is flexible and lightweight; the bent connecting cable head 336, together with the elastic buckle 3361, makes the connection between the first cable 333, the second cable 335 and the linkage component 33 and the locking tongue 322 faster, easier to install and maintain, lower cost, and smaller installation space.

[0090] The swing arm 331 and bracket 332 in this application can be formed by cold rolling and stamping processes. In other embodiments, they can be formed by machining, die casting or other methods using metal alloys or other materials. The main body of the first cable 333 and the second cable 335 can be made of steel wire rope or other high-strength rope. The connecting cable head 336 can be made of steel, aluminum or other materials. The first cable 333, the second cable 335 and the connecting cable head 336 can be connected by crimping, welding, riveting or other methods. The buckle 3361 can be made of plastic or metal. No restrictions are imposed here.

[0091] In the application of the tailgate auxiliary lock structure 30 of the automobile 100 of this application, two sets of tailgate auxiliary lock structures 30 are installed at the upper and lower ends of either side door. When the automobile tailgate 10 is closed, the left door 16 and the right door 17 are combined. Under the action of the return spring 3222 of the latch 322, the pin 3221 of the latch 322 moves vertically upward along the installation direction of the lock body bracket 321, first passing through the latch through hole 151 of the top plate 15 of the left door 16, and then moving upward to insert into the insertion hole 3111 of the latch 31, thus completing the locking; opening When the tailgate 10 is opened, pulling the door handle 11 causes the first cable 333 of the linkage component 33 to pull the first hole 3311 of the swing arm 331. Under the upward pulling force of the first cable 333, the swing arm 331 swings counterclockwise around the second hole 3312. That is, the third hole 3313 of the swing arm 331 drives the second cable 335 to move downward, which in turn drives the pin 3221 of the latch 322 to move vertically downward out of the insertion hole 3111 of the latch 31, thus completing the unlocking.

[0092] In summary, the latch 31 in this application is concealed within the outer edge of the roof 20, ensuring that it does not protrude from the roof 20 of the vehicle 100. This structure eliminates the risk of head injury caused by the latch 31 protruding when a person passes through the tailgate 10 or retrieves goods. Simultaneously, the linkage mechanism formed by the door handle 11 driving the linkage component 33 and the latch 322, which moves the latch 322 vertically out of the latch 31, reduces the movement space of the latch 322 and simplifies the locking structure. This solves the problems of the existing vehicle 100's secondary lock latch 31 protruding and exposed, leading to the risk of head injury, high unlocking force, and poor operational feel. The tailgate secondary lock structure 30 of this application has the advantages of small size, concealed installation, and easier door opening, improving the convenience of getting in and out of the vehicle and providing good operability.
