[0031] in, Figure 1 The reference direction coordinate system of this utility model embodiment is given below, in conjunction with Figure 1 The embodiments of this utility model will be described in the directions shown.

[0032] See Figures 1-3 An embodiment of this utility model provides a car tailgate structure, including a tailgate and a locking device 100. The tailgate includes a hatchback tailgate component 201 and a trunk lid tailgate component 202. The hatchback tailgate component 201 is provided with a first hinge (not shown in the figure) for connecting to the car body. The first hinge can be disposed at the front end of the hatchback tailgate component 201. The trunk lid tailgate component 202 is disposed at the rear of the hatchback tailgate component 201 and is connected to the rear of the hatchback tailgate component 201 through a second hinge 203.

[0033] See Figure 6The locking device 100 is disposed between the hatchback tailgate component 201 and the trunk lid tailgate component 202, and is used to lock or unlock the hatchback tailgate component 201 and the trunk lid tailgate component 202 in different open states. Specifically, the locking device 100 can lock the hatchback tailgate component 201 and the trunk lid tailgate component 202, so that the hatchback tailgate component 201 and the trunk lid tailgate component 202 form a whole and can be opened or closed around the first hinge; the locking device 100 can unlock the hatchback tailgate component 201 and the trunk lid tailgate component 202, so that the trunk lid tailgate component 202 can be opened or closed independently around the second hinge 203.

[0034] Combination Figures 1-3 In this utility model, the tailgate includes a hatchback tailgate component 201 and a trunk lid tailgate component 202, configured as a dual tailgate opening method. This allows the same vehicle to simultaneously have both hatchback and trunk lid opening methods. After the locking device 100 is unlocked, the trunk lid tailgate component 202 can be opened or closed independently around the second hinge 203, thus achieving the trunk lid opening method. When the locking device 100 is locked, the hatchback tailgate component 201 and the trunk lid tailgate component 202 form a whole, allowing them to be opened or closed around the first hinge, thus achieving the hatchback opening method. In over 90% of daily scenarios, the trunk lid opening method is used for convenience. When loading or unloading large items, the hatchback opening method is used. This greatly expands the usage scenarios of the car tailgate.

[0035] It is understood that the locking device 100 may be an electromagnet-type locking device or a pin-type locking device. See also the following embodiments: Figures 1-6 The locking device 100 includes a lock seat 101, which is provided with an electric lock tongue 102. The electric lock tongue 102 can be driven by a motor or an electromagnet and can be extended or retracted by electric drive. The lock seat 101 is located at the rear of the hatchback tailgate component 201, and the tailgate component 202 is provided with a lock hole that can cooperate with the electric lock tongue 102. When it is necessary to lock the hatchback tailgate component 201 and the tailgate lid component 202, the electric latch 102 of the lock base 101 extends and inserts into the lock hole. The hatchback tailgate component 201 and the tailgate lid component 202 are locked together by the electric latch 102 to form a synchronous opening structure, preventing the tailgate lid component 202 from opening or closing independently around the second hinge 203. When it is necessary to unlock the hatchback tailgate component 201 and the tailgate lid component 202, the electric latch 102 of the lock base 101 retracts and exits from the lock hole. At this time, the tailgate lid component 202 can be opened or closed independently around the second hinge 203.

[0036] Furthermore, in some embodiments, see Figure 4 , Figure 5 , Figure 6The lock seat 101 is provided with a mounting part 103. The lock seat 101 is mounted to the rear of the hatchback tailgate component 201 through the mounting part 103. The lock seat 101 extends rearward from the hatchback tailgate component 201. The electric lock tongue 102 is laterally telescopically mounted on the lock seat 101. The tailgate component 202 is provided with a lock block 204 that is laterally offset from the lock seat 101. The lock hole 205 is provided on the side of the lock block 204 facing the lock seat 101. In this embodiment, an independent lock block 204 is provided on the tailgate component 202, and the lock seat 101 extends rearward from the hatchback tailgate component 201, thereby forming a structure that is laterally offset. The locking and unlocking of the hatchback tailgate component 201 and the tailgate component 202 are achieved by means of the laterally arranged electric lock tongue 102 and the lock hole 205.

[0037] Furthermore, in some embodiments, see Figures 4-6 The lock base 101 has a first protrusion 104 extending laterally at its bottom, and a first support surface 105 formed at the top of the first protrusion 104. The lock block 204 has a second protrusion 206 extending laterally at its top, and a second support surface 207 formed at the bottom of the second protrusion 206. The second support surface 207 of the second protrusion 206 can overlap with the first support surface 105 along with the tailgate / tailgate component 202. In this embodiment, the overlapping cooperation of the first support surface 105 and the second support surface 207 improves the alignment accuracy between the electric lock tongue 102 and the lock hole 205, ensuring that the electric lock tongue 102 and the lock hole 205 can be accurately matched.

[0038] Furthermore, in some embodiments, see Figure 4 , Figure 5 The electric latch 102 includes a first electric latch 106 disposed on the top side face of the lock base 101 and a second electric latch 107 disposed on the side face of the first boss 104. The lock hole 205 includes a first lock hole 208 disposed on the side face of the second boss 206 and a second lock hole 209 disposed on the bottom side face of the lock block 204. In this embodiment, the electric latch 102 is provided in two stages on the lock base 101, and the lock hole 205 is provided in two stages on the lock block 204, which fully ensures the stability of the hatchback tailgate component 201 and the tailgate lid tailgate component 202 after locking, and avoids locking failure.

[0039] In some embodiments, see Figure 6 The hatchback tailgate component 201 includes an outer frame 210 and a rear windshield 211 disposed on the outer frame 210. After the locking device 100 is locked, the hatchback tailgate component 201 and the tailgate lid component 202 form a whole, thereby enabling it to be opened or closed around the first hinge, that is, realizing a hatchback opening mode, which can meet the needs of loading and unloading larger items in the rear trunk of the car.

[0040] In some embodiments, Figure 1 , Figure 2 , Figure 3 , Figure 6 The hatchback tailgate component 201 is equipped with an electric strut 300 for connection to the vehicle body. With the help of the electric strut 300, the hatchback tailgate component 201 and the tailgate tailgate component 202 can be opened more conveniently after the locking device 100 is locked.

[0041] The electric strut 300 has one end mounted to the rear inner panel of the outer frame 210 via a ball joint, and the other end mounted to the side panel of the vehicle via a ball joint.

[0042] See Figure 1 , Figure 2 , Figure 3 , Figure 6 The second hinge 203 is installed on the rear inner panel of the outer frame 210, and the second hinge 203 is connected to the inner panel of the tailgate assembly 202 via a hook-shaped bracket 212. The hook-shaped bracket ensures that when the tailgate assembly 202 is opened alone, it avoids interference with the hatchback tailgate assembly 201.
