[0002] As a representative of individuality and fashion in the automotive industry, convertibles are increasingly favored by consumers. As a classic style of convertibles, soft-top convertibles occupy an important position in the convertible market with their advantages such as simple structure, small space occupation and low cost. When the roof is not opened, the roof folding mechanism is stored in the rear cover box. When the roof folding mechanism moves, the rear cover box also needs to move. As one of the core mechanisms of the rear cover box, the rear cover locking mechanism has a direct impact on the movement trajectory of the roof folding mechanism and the shape of the entire vehicle.

In order to avoid the interference between the folding mechanism of the soft-top convertible and the rear cover during the opening process, the existing technology generally adopts an outward-turning opening (towards the rear of the vehicle) of the rear cover. The locking device required for this movement process has the disadvantages of being complicated, costly, easy to damage and inconvenient to repair; and the complex locking device structure also causes the convertible vehicle to open and close malfunctions, and has poor reliability.

[0031] Unless otherwise defined, all technical and scientific terms used in this utility model have the same meaning as those commonly understood by technicians in the technical field of this utility model. The terms used in the specification of this utility model are only for the purpose of describing specific embodiments and are not intended to limit this utility model. The term "and / or" used in this utility model includes any and all combinations of one or more related listed items.

[0032] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0033] The utility model provides a vehicle, please refer to Figure 1 , specifically a vehicle with a convertible structure. The vehicle includes a convertible rear cover 013 and a locking device, and the locking device is installed on the convertible rear cover 013. The convertible rear cover 013 has an upward movement trajectory, which fully guarantees the appearance shape space of the convertible rear cover 013 and the design space of the luggage compartment. The locking device is used to lock the convertible rear cover 013 after it is closed.

[0034] In one implementation, please refer to Figures 2 to 4 The locking device includes a mounting bracket 003, a first rod 004 and a locking tongue 002; wherein the first rod 004 is rotatably connected to the mounting bracket 003; the locking tongue 002 is rotatably connected to the first rod 004, and the first rod 004 drives the locking tongue 002 to move so that the locking tongue 002 engages with the locking ring 001 or unlocks the locking ring 001.

[0035] Specifically, the mounting bracket 003 may be a flat plate structure, and the first rod 004 may be rotatably mounted on the mounting bracket 003. The first rod 004 may be in the shape of a long bar.

[0036] Optionally, the mounting bracket 003 is fixedly connected to the convertible rear cover 013. The mounting bracket 003 may be provided with a first fixing hole 016 and a second fixing hole 017, and the mounting bracket 003 is fixedly connected to the convertible rear cover 013 through the first fixing hole 016 and the second fixing hole 017.

[0037] The lock tongue 002 is connected to the first rod 004, so that the mounting bracket 003, the first rod 004 and the lock tongue 002 together form a linkage structure. That is, the first rod 004 can rotate relative to the mounting bracket 003, and when the first rod 004 rotates, the lock tongue 002 can be driven to move.

[0038] Optionally, the locking tongue 002 is used to be connected and fixed with the locking ring 001. It can be understood that the locking device includes a locked state and an unlocked state. In the locked state, the locking tongue 002 and the locking ring 001 are engaged, so that the convertible rear cover 013 is closed and cannot be opened; in the unlocked state, the locking tongue 002 moves to escape from the locking ring 001, so that the convertible rear cover 013 can be opened.

[0039] The utility model provides a locking device, which is applied in a vehicle, and in particular in a convertible rear cover 013 of a convertible. The locking device comprises a mounting bracket 003, a first rod 004 rotatably connected to the mounting bracket 003, and a locking tongue 002 connected to the first rod 004. Driven by the first rod 004, the locking tongue 002 can move along a specific trajectory to complete the task of locking or unlocking; the device has a simple structure, low manufacturing cost, is not easy to be damaged, and is easy to maintain, so that the convertible opening and closing reliability of the convertible vehicle is high.

[0040] In one implementation, please refer to Figures 2 to 4 The locking device includes a first fixing member 008 , the first fixing member 008 is mounted on the mounting bracket 003 , the first rod 004 is connected to the first fixing member 008 , and the locking tongue 002 is rotatably connected to the first rod 004 through the first fixing member 008 .

[0041] In one implementation, please refer to Figures 2 to 4The lock tongue 002 is provided with a lock tongue slot, which is used to clamp the lock ring 001. The lock tongue slot extends along an arc from one end of the lock tongue 002. The first fixing member 008 has a preset motion trajectory, which is consistent with the extension direction of the lock tongue slot on the lock tongue 002.

[0042] Specifically, the lock tongue 002 may be in the shape of a rod, and a linkage structure is formed between the lock tongue 002, the first rod 004 and the mounting bracket 003. The lock tongue 002 moves along a specific trajectory, and the contour of its motion trajectory is consistent with the notch contour line 021; the lock tongue 002 is separated from the lock ring 001 along the notch contour line 021, which is the unlocking process. Therefore, the convertible rear cover 013 fixed to the mounting bracket 003 moves along the notch contour line 021 (lift-up type).

[0043] In one implementation, please refer to Figures 2 to 4 The locking device includes a second fixing member 014 , which is mounted on the mounting bracket 003 , and one end of the first rod 004 away from the first fixing member 008 is connected to the second fixing member 014 , and the first rod 004 rotates around the second fixing member 014 .

[0044] Specifically, the second fixing member 014 may be a bolt. The second fixing member 014 is fixedly connected to the mounting bracket 003, and one end of the first rod 004 is rotatably connected to the second fixing member 014. The first fixing member 008 and the second fixing member 014 may define a motion trajectory of the first rod 004, so that the first rod 004 rotates around the axis of the second fixing member 014.

[0045] In one implementation, please refer to Figures 2 to 4 The locking device includes a third fixing member 015, which is connected to the mounting bracket 003 and the lock tongue 002; and the third fixing member 015 is spaced apart from the first fixing member 008. Through the restriction of the first fixing member 008 and the third fixing member 015, the first rod 004 drives the lock tongue 002 to move along a preset motion trajectory to unlock or lock.

[0046] In one implementation, please refer to Figures 2 to 4 The locking device includes a second rod 006, which is rotatably connected to the mounting bracket 003; the second rod 006 is also rotatably connected to the third fixing member 015.

[0047] Specifically, the second rod 006 and the first rod 004 are rotatably mounted on the mounting bracket 003. The second rod 006 and the first rod 004 can both be in the shape of long bars, and the second rod 006 and the first rod 004 are spaced apart on the mounting bracket 003.

[0048] The lock tongue 002 connects the second rod 006 and the first rod 004, so that the mounting bracket 003, the second rod 006, the first rod 004 and the lock tongue 002 together form a four-bar linkage structure. That is, the second rod 006 and the first rod 004 can rotate relative to the mounting bracket 003, and when the second rod 006 and the first rod 004 rotate, the lock tongue 002 can be driven to move.

[0049] It should be explained that in the length direction of the second rod 006, the mounting bracket 003 and the locking tongue 002 are respectively connected to the two opposite ends of the second rod 006; in the length direction of the first rod 004, the mounting bracket 003 and the locking tongue 002 are respectively connected to the two opposite ends of the first rod 004.

[0050] For example, when the second rod 006 and the first rod 004 drive the locking tongue 002 to move, the two rods rotate in the same direction relative to the mounting bracket 003; that is, when the second rod 006 rotates clockwise, the first rod 004 also rotates clockwise. Figure 5 As shown, in the locked state, the second rod 006 has an angle α1 with the first direction, the first rod 004 has an angle β1 with the second direction, the lock tongue 002 has an angle γ1 with the second rod 006, and the lock tongue 002 has an angle δ1 with the first rod 004. Then, in the process of switching from the locked state to the unlocked state, it is necessary to drive the second rod 006 and the first rod 004 to drive the lock tongue 002 to rotate. In the unlocked state, the second rod 006 has an angle α2 with the first direction, the first rod 004 has an angle β2 with the second direction, the lock tongue 002 has an angle γ2 with the second rod 006, and the lock tongue 002 has an angle δ2 with the first rod 004. Moreover, α1 and α2 may be different, β1 and β2 may be different, γ1 and γ2 may be different, and δ1 and δ2 may be different.

[0051] Optionally, the locking device can be automatically controlled or manually controlled. The external power can act on the second rod 006 or the first rod 004. For example, the external power can act on the first rod 004 to rotate the first rod 004, so that the first rod 004 drives the lock tongue 002 to move, and the lock tongue 002 is unlocked in a preset path under the restriction of the second rod 006.

[0052] Optionally, the second rod 006 and the first rod 004 have different lengths, that is, the second rod 006 and the first rod 004 have different rotation radius. It can be understood that the second rod 006 and the first rod 004 both rotate relative to the mounting bracket 003, so the rotation paths of the second rod 006 and the first rod 004 are both arc-shaped. In addition, the rotation radius of the second rod 006 is the length of the second rod 006, and the rotation radius of the first rod 004 is the length of the first rod 004.

[0053] In one implementation, please refer to Figures 2 to 4The locking device includes a fourth fixing member 009 , which is connected to the mounting bracket 003 , an end of the second rod 006 away from the third fixing member 015 is connected to the fourth fixing member 009 , and the second rod 006 rotates around the fourth fixing member 009 .

[0054] Specifically, the fourth fixing member 009 may be a bolt. The fourth fixing member 009 is fixedly connected to the mounting bracket 003, and one end of the second rod 006 is rotatably connected to the fourth fixing member 009. The second fixing member 014 is fixedly connected to the mounting bracket 003, and one end of the first rod 004 is rotatably connected to the second fixing member 014.

[0055] Optionally, the second rod 006 is sleeved on the fourth fixing member 009, and a fixing nut 010 is installed on the side of the second rod 006 facing away from the mounting bracket 003. Similarly, the first rod 004 is sleeved on the second fixing member 014, and a fixing nut 010 is also installed on the side of the third connecting rod facing away from the mounting bracket 003. A plastic gasket 018 is provided between the second rod 006 and the mounting bracket 003, and a plastic gasket 018 is also provided between the first rod 004 and the mounting bracket 003.

[0056] Furthermore, one end of the second rod 006 away from the fourth fixing member 009 is connected to the third fixing member 015 and rotates around the third fixing member 015, one end of the first rod 004 away from the second fixing member 014 is connected to the first fixing member 008 and rotates around the first fixing member 008, and the locking tongue 002 is rotationally connected to the third fixing member 015 and the first fixing member 008.

[0057] Optionally, the third fixing member 015 can be a bolt with a hole at the tail, and the first fixing member 008 can be a common bolt. The other end of the second rod 006 is connected to the third fixing member 015 in a rotational manner. The other end of the first rod 004 is connected to the first fixing member 008 in a rotational manner. Then, the lock tongue 002 is connected to the second rod 006 through the third fixing member 015, and the lock tongue 002 is also connected to the first rod 004 through the first fixing member 008.

[0058] Optionally, along the length direction of the lock tongue 002 , the lock tongue notch, the third fixing member 015 and the first fixing member 008 are arranged in sequence.

[0059] In one embodiment, a first slot 020 is formed on the mounting bracket 003 , and the first fixing member 008 extends into the first slot 020 and slides along the extending direction of the first slot 020 .

[0060] In one embodiment, a second slot 019 is formed on the mounting bracket 003 , and the third fixing member 015 extends into the second slot 019 and slides along the extension direction of the second slot 019 . The extension direction line of the second slot 019 is the same as the extension direction line of the first slot 020 .

[0061] Specifically, the second notch 019 and the first notch 020 are both arc-shaped. It can be understood that since the second rod 006 rotates around the fourth fixing member 009 and the first rod 004 rotates around the second fixing member 014, the rotation paths of the second rod 006 and the first rod 004 are also arc-shaped. The second notch 019 and the first notch 020 are used to accommodate the third fixing member 015 and the first fixing member 008, and are used to limit the rotation distance of the second rod 006 and the first rod 004.

[0062] Among them, the third fixing member 015 extends into the second notch 019 on the mounting bracket 003, and the first fixing member 008 extends into the first notch 020 on the mounting bracket 003. The third fixing member 015 slides in the second notch 019, so the locking tongue 002 connected to the third fixing member 015 also slides relatively; the first fixing member 008 slides in the first notch 020, so the locking tongue 002 connected to the first fixing member 008 also slides relative to the first notch 020. Therefore, the third fixing member 015 slides along the second notch 019, the first fixing member 008 slides along the first notch 020, and the locking tongue 002 is fixedly connected to the third fixing member 015 and the first fixing member 008 respectively, so the locking tongue 002 also moves relative to the fixing bracket.

[0063] In one implementation, please refer to Figures 2 to 4 The mounting bracket 003 includes a first surface and a second surface facing each other, the second notch 019 and the first notch 020 both extend from the first surface to the second surface, the second rod 006 and the first rod 004 are both mounted on the first surface, and the locking tongue 002 is mounted on the second surface.

[0064] In one implementation, please refer to Figures 2 to 4 The locking device also includes a fixed shaft 007 and an elastic member 005. The fixed shaft 007 is connected and fixed to the mounting bracket 003. The two ends of the elastic member 005 are respectively connected to the fixed shaft 007 and the third fixing member 015. The elastic member 005 is telescopically deformed along the fixed shaft 007 toward the direction of the third fixing member 015.

[0065] Specifically, the fixed shaft 007 can be a bolt with a hole at the rear, and the fixed shaft 007 is fixedly connected to the mounting bracket 003, and the elastic member 005 is a spring, and the two ends of the elastic member 005 are respectively connected to the fixed shaft 007 and the third fixing member 015. The fixed shaft 007 is fixed on the mounting bracket 003 and does not move, and the third fixing member 015 slides in the groove, and the elastic member 005 fixed to the fixed shaft 007 and the third fixing member 015 is stretched or compressed due to the sliding of the third fixing member 015 in the second notch 019.

[0066] Optionally, a gasket 011 is also provided on the fixed shaft 007 to increase the contact area, reduce pressure, prevent loosening between components, and protect the mounting bracket 003 and the fixed shaft 007 from damage.

[0067] It can be understood that the elastic member 005 can exert an elastic force on the third fixing member 015, thereby driving the third fixing member 015 and the second rod 006 to move. In the locked state, the elastic member 005 can be in a normal state, that is, the elastic member 005 does not undergo elastic deformation and does not have elastic potential energy. In the process of switching from the locked state to the unlocked state, the elastic member 005 is stretched and deformed under the drive of the second rod 006. In the unlocked state, the elastic member 005 is in a stretched state, that is, the elastic member 005 is deformed and has elastic potential energy. Therefore, after the external power is removed, the elastic member 005 can drive the second rod 006 to recover.

[0068] In one implementation, please refer to Figures 2 to 4 , the length of the first rod 004 is greater than the length of the second rod 006. Specifically, the length of the first rod 004 is greater than the length of the second rod 006, so the rotation radius of the first rod 004 is larger than that of the second rod 006.

[0069] In one implementation, please refer to Figure 4 and Figure 6 The locking device also includes a ball head 012, a ball socket 023 and a support rod 022. The ball head 012 is connected to the first rod 004, and the ball head 012 is also connected to the support rod 022 through the ball socket 023.

[0070] Specifically, the locking device includes a ball head 012, a ball socket 023, a support rod 022 and a piston rod 024. The ball head 012 is fixedly connected to the first fixing member 008 and is located at one end of the first fixing member 008 on the first surface. The ball socket 023 is connected to the ball head 012, the support rod 022 is connected to the ball socket 023, and the piston rod 024 is connected to the support rod 022. The locking device is driven by the telescopic movement of the piston rod 024, thereby linking the ball head 012 to drive the first fixing member 008 to move in the first slot 020.

[0071] In one embodiment, if Figure 2 As shown, at this time, the lock tongue 002 is stuck in the lock ring 001, the elastic member 005 is in an undeformed state, and the third fixing member 015 connected to the elastic member 005 is subjected to the tension in the X direction (including the X1 direction), so the lock tongue 002 connected to the third fixing member 015 is also subjected to the X direction force of the tension spring, and deviates away from the Y direction (including the Y1 direction), ensuring that the lock tongue 002 is firmly stuck in the lock ring 001, reducing the risk of the lock tongue 002 and the lock ring 001 not being stuck (locked) tightly and having a gap. If the convertible cover is not locked tightly, it may cause problems such as abnormal noise of the vehicle and poor wading performance.

[0072] In one embodiment, in order to avoid abnormal noise that may be generated during the clamping process of the lock tongue 002 and the surface friction between the lock ring 001 and the mounting bracket 003, the relevant parts of the lock tongue 002 can be plastic-coated.

[0073] In one embodiment, when the gas spring or electric spring pulls the ball head 012 to move along the first slot 020 of the mounting bracket 003, the elastic member 005 is stretched; because the lock tongue 002 is connected to the ball through the first fixing member 008, the lock tongue 002 will also move relatively when the gas spring or electric spring pulls the ball head 012 to move. Since the third fixing member 015 is fixedly connected to the lock tongue 002, when the lock tongue 002 moves relatively, the third fixing member 015 will also slide between the second slot 019 of the mounting bracket 003.

[0074] In one embodiment, one end of the second rod 006 is connected to the mounting bracket 003 through the fourth fixing member 009, and the other end is connected to the third fixing member 015; one end of the first rod 004 is connected to the mounting bracket 003 through the second fixing member 014, and the other end is connected to the first fixing member 008; when the gas spring or the electric spring pulls the ball head 012 to move (negative X direction), a four-bar linkage is formed between the lock tongue 002, the second rod 006, the first rod 004 and the mounting bracket 003, and the lock tongue 002 moves along a specific trajectory.

[0075] In one embodiment, if Figure 1 As shown, when the convertible rear cover 013 is opened along the track of the locking tongue slot, the soft-top convertible folding structure unfolds.
