[0030] As a frequently used part of a car, the tailgate is usually switched between open and closed states through a lock body and a lock catch. As people's requirements for the appearance of the car body increase, the exposed tailgate lock catch is increasingly complained by users. In order to improve the aesthetics of the B-side, a flap structure is usually added to the door sill trim so that the lock catch can be covered by the flap structure after the car door is opened.
[0031] However, after the vehicle body is added with a flip cover structure, the lateral limit block previously arranged on the lock buckle to overcome the slight friction noise between the lock buckle and the lock body needs to be removed to avoid the flipping space of the flip cover structure. Without the fixed limit of the lateral limit block, the lock body is easy to shift laterally relative to the lock buckle, and the lock body and the lock buckle rub against each other to produce abnormal noise. Therefore, the vehicle body still needs to add a lateral limit structure to fix the lock body, but it needs to avoid the layout space of the flip cover structure.
[0032] In view of this, the embodiment of the utility model provides a tailgate lock, a tailgate and a vehicle, wherein a limiting structure is movably arranged on the vehicle body, and in the initial state, the limiting structure is away from the lock buckle and has a preset distance with the lock buckle. When the lock body is engaged with the lock buckle, the limiting structure can move toward the lock buckle and abut against the side of the lock body, and the limiting structure applies a force to the lock body, and the lock body is kept in a fixed state with the lock buckle under the action of the limiting structure, thereby preventing the lock body and the lock buckle from rubbing against each other and making abnormal noises, thereby improving the driving experience. Since the limiting structure is movably arranged on the vehicle body, the movement space of the flap can be avoided, and the opening and closing of the flap will not be interfered with, so as to ensure that the flap can play the effect of covering the lock buckle after the tailgate is opened, thereby improving the aesthetics of the vehicle body trim.
[0033] In order to better understand the above technical solution, the above technical solution is described in detail below with reference to the accompanying drawings.
[0034] like Figure 1 As shown, the embodiment of the utility model provides a tailgate lock, which is applied to a tailgate, and the tailgate is rotatably arranged on the vehicle body, and the tailgate lock includes:
[0035] A lock body 10 is provided on the tailgate;
[0036] A lock buckle 20 is provided on the vehicle body, and the lock buckle 20 is used to cooperate with the lock body 10; and
[0037] The limiting structure 30 is movably arranged on the vehicle body; when the lock body 10 and the lock buckle 20 are engaged, the limiting structure 30 moves toward the lock body 10 to abut against the side surface of the lock body 10; when the limiting structure 30 and the lock body 10 are separated, the lock buckle 20 releases the lock body 10.
[0038] In the technical solution adopted in this embodiment, the lock body 10 can be engaged with the lock buckle 20 to close the tailgate, and the lock body 10 can be separated from the lock buckle 20 to open the tailgate, thereby realizing the opening and closing of the tailgate. During the driving process of the vehicle, the lock body 10 is easy to move relative to the lock buckle 20, and the friction between the lock body 10 and the lock buckle 20 produces abnormal noise. To this end, the embodiment of the utility model is provided with a limiting structure 30, which is movably arranged on the vehicle body. In the initial state, the limiting structure 30 is away from the lock buckle 20 and has a preset distance with the lock buckle 20. When the lock body 10 is engaged with the lock buckle 20, the limiting structure 30 can move toward the lock buckle 20 and abut against the side of the lock body 10. The limiting structure 30 applies a force to the lock body 10. Under the action of the limiting structure 30, the lock body 10 remains in a fixed state with the lock buckle 20, thereby preventing the lock body 10 and the lock buckle 20 from rubbing against each other and producing abnormal noise, thereby improving the driving experience. When the tailgate needs to be opened, the limiting structure 30 moves away from the lock buckle 20, the limiting structure 30 is separated from the lock body 10, and then the lock body 10 and the lock buckle 20 are unlocked, so that the tailgate is opened. In addition, the limiting structure 30 is movably arranged on the vehicle body, which can avoid the movement space of the flip cover 40 and will not interfere with the opening and closing of the flip cover 40, ensuring that the flip cover 40 can cover the lock buckle 20 after the tailgate is opened, thereby improving the aesthetics of the vehicle body trim.
[0039] Specifically, the tailgate lock is applied to the tailgate of a car. An opening is provided on the body of the car, and the tailgate is rotatably connected to the body. By rotating the tailgate, the opening can be opened or closed, thereby realizing the opening or closing of the trunk.
[0040] The tailgate lock includes a lock body 10, a lock catch 20 and a limiting structure 30. The lock body 10 is arranged on the tailgate and can rotate synchronously with the tailgate. The lock body 10 is used to cooperate with the lock catch 20 to lock and fix the tailgate to the vehicle body, realize the closure of the tailgate, and prevent the tailgate from opening accidentally. The lock catch 20 is arranged on the threshold trim 50 of the vehicle body, and is used to cooperate with the lock body 10 to realize the opening and closing of the tailgate. The flap 40 is arranged on the threshold trim 50, and is used to cover the lock catch 20, so as to enhance the aesthetics of the vehicle body. In this embodiment, the lock body 10, the lock catch 20 and the flap 40 can adopt the product structure commonly used on the market. They are not the technical improvement focus of the utility model and are not limited here.
[0041] The limiting structure 30 is disposed on the threshold trim 50 of the vehicle body and can move on the threshold trim 50. That is, the limiting structure 30 can move on the threshold trim 50, so as to move toward or away from the lock buckle 20. In the initial state, the limiting structure 30 is located on one side of the lock buckle 20, and there is a preset distance between the limiting structure 30 and the lock buckle 20 to avoid the movement of the flip cover 40. The preset distance can be set according to the movement space of the flip cover 40, which is not limited here. When the lock body 10 needs to be limited, that is, after the lock body 10 is engaged with the lock buckle 20, the limiting structure 30 moves toward the lock buckle 20 until the limiting structure 30 abuts against the side of the lock body 10, and generates a force on the lock body 10 to limit the lateral movement of the lock body 10, thereby preventing the lock body 10 and the lock buckle 20 from rubbing against each other and generating abnormal noise. When the tailgate needs to be opened, the limiting structure 30 is first moved away from the lock catch 20 to separate the limiting structure 30 from the lock body 10, and then the lock body 10 and the lock catch 20 are unlocked to open the tailgate. In one embodiment, the limiting structure 30 can be a slide bar or a slider, which is slidably disposed on the threshold trim 50 of the vehicle body, and can move toward or away from the lock catch 20 through the movement of the slide bar or the slider. In order to ensure that the slide bar or the slider slides in a predetermined direction, a slide groove or a slide rail can be disposed on the threshold trim 50, and the slider or the slide bar can be slidably disposed in the slide groove or the slide rail.
[0042] For example, in one embodiment of the present invention, the limiting structure 30 is arranged on one side of the lock buckle 20 along the width direction of the vehicle body. The space of the vehicle body is limited. In order to reduce the occupation of storage space such as the trunk of the car, the limiting structure 30 is arranged on one side of the lock buckle 20 along the width direction of the vehicle body. In this way, the space in the width direction of the vehicle body is used to set the limiting structure 30, which reduces the space occupation in the length direction of the vehicle body, thereby preventing the limiting structure 30 from extending toward the trunk and occupying the trunk space, thereby ensuring the spaciousness of the trunk space to place more items.
[0043] Exemplarily, in one embodiment of the utility model, the angle between the movement direction of the limiting structure 30 and the width direction of the vehicle body is zero degree or an acute angle. It is understandable that in order to ensure the reliability of the side contact between the limiting structure 30 and the lock body 10, the angle between the movement direction of the limiting structure 30 and the width direction of the vehicle body is zero degree or an acute angle. In other words, the movement direction of the limiting structure 30 is perpendicular to the side of the lock body 10, so that the limiting structure 30 can be closely contacted with the side of the lock body 10. Specifically, if the side of the lock body 10 is a plane parallel to the length direction of the vehicle body, the angle between the movement direction of the limiting structure 30 and the width direction of the vehicle body is zero degree, that is, the movement direction of the limiting structure 30 and the width direction of the vehicle body, the limiting structure 30 can be closely contacted with the side of the lock body 10, thereby improving the reliability of the fixed limit of the lock body 10. If the side surface of the lock body 10 is an inclined surface inclined with respect to the length direction of the vehicle body, the included angle between the movement direction of the limiting structure 30 and the width direction of the vehicle body is an acute angle, so that the limiting structure 30 can also be closely abutted against the side surface of the lock body 10. In actual application, the preferred selection can be made according to the specific conditions of the side surface of the lock body 10, and no limitation is made here.
[0044] For example, refer to Figure 1-Figure 3 In one embodiment of the utility model, the limiting structure 30 includes a telescopic member 31, the free end of the telescopic member 31 is slidably connected to the vehicle body, the fixed end of the telescopic member 31 is fixedly connected to the vehicle body, the free end of the telescopic member 31 is extended to abut against the lock body 10, and the free end of the telescopic member 31 is contracted to separate from the lock body 10. Specifically, the limiting structure 30 includes a telescopic member 31, the telescopic member 31 has a free end and a fixed end, the fixed end of the telescopic member 31 is fixedly set on the vehicle body, and has a preset distance with the lock buckle 20, through the connection between the fixed end of the telescopic member 31 and the vehicle body, the telescopic member 31 can be installed on the vehicle body, and the reliable movement of the free end of the telescopic member 31 is guaranteed. The free end of the telescopic member 31 is movably connected to the vehicle body, that is, the free end of the telescopic member 31 is telescopic relative to the fixed end of the telescopic member 31, and the sliding setting with the vehicle body is achieved by the telescopic free end of the telescopic member 31. It is understandable that when the free end of the telescopic member 31 is extended, the free end of the telescopic member 31 slides relative to the vehicle body and moves toward the lock buckle 20 until it abuts against the side of the lock body 10; when the free end of the telescopic member 31 is retracted, the free end of the telescopic member 31 slides relative to the vehicle body and moves away from the lock buckle 20 until it is separated from the lock body 10. In this embodiment, the lock body 10 is fixed in position by setting the telescopic member 31. The telescopic member 31 is smaller in size in the retracted state, which can reduce the space occupied and can be installed and used in a small space to improve versatility. In one embodiment, the telescopic member 31 can be an electric support rod, a cylinder, etc., which is not limited here.
[0045] For example, refer to Figure 1-Figure 3In one embodiment of the utility model, the limiting structure 30 further includes an elastic member 32, which is arranged at the free end of the telescopic member 31, and the elastic member 32 is used to elastically contact the lock body 10. By setting the elastic member 32, the limiting structure 30 can be prevented from rigidly abutting the side of the lock body 10, thereby reducing the possibility of damaging the lock body 10. Moreover, the elastic member 32 will be deformed and generate elastic force when it is squeezed between the limiting structure 30 and the lock body 10, thereby forming a reaction force on the lock body 10, and cooperate with the abutment force of the limiting structure 30 to jointly limit and fix the lock body 10, thereby improving the reliability of the lock body 10. Specifically, the elastic member 32 is arranged at the free end of the telescopic member 31, and the free end of the telescopic member 31 is extended, so that the elastic member 32 is sandwiched between the side of the lock body 10 and the free end of the telescopic member 31, and jointly abuts against the lock body 10. In one embodiment, the elastic member 32 can be a rubber pad, a silicone pad, etc., which is not limited here.
[0046] Exemplarily, in one embodiment of the utility model, the free end of the telescopic member 31 is provided with a mounting groove, and the elastic member 32 protrudes from the mounting groove. In order to facilitate the assembly of the elastic member 32, a mounting groove is provided at the free end of the telescopic member 31, one end of the elastic member 32 is embedded in the mounting groove, and the other end of the telescopic member 31 protrudes from the mounting groove for abutting the side of the lock body 10. It can be understood that by setting the mounting groove, the elastic member 32 can be better fixed, and the elastic member 32 can be prevented from bending and affecting the deformation. In one embodiment, the elastic member 32 is interference fit with the mounting groove, so that the reliability of the elastic member 32 being fixed in the mounting groove can be improved. In other embodiments, the elastic member 32 can also be fixed in the mounting groove by bonding, which is not limited here.
[0047] For example, refer to Figure 1 and Figure 3 In one embodiment of the utility model, the limiting structure 30 includes a limiting groove 33 provided on the vehicle body, and the fixed end of the telescopic member 31 is provided in the limiting groove 33. In order to better fix the telescopic member 31, a limiting groove 33 is provided on the door sill trim 50 of the vehicle body, and the fixed end of the telescopic member 31 is fixed in the limiting groove 33. The fixed end of the telescopic member 31 can be limited by the limiting groove 33, thereby improving the firmness of the fixed end of the telescopic member 31 fixed to the vehicle body. In one embodiment, the fixed end of the telescopic member 31 is interference fit with the limiting groove 33, which can further improve the reliable fixation of the fixed end of the telescopic member 31. Of course, in other embodiments, the fixed end of the telescopic member 31 can also be fixed in the limiting groove 33 by means of clamping, welding, and screwing, which are not limited here.
[0048] For example, refer to Figure 1-Figure 3In one embodiment of the utility model, the tailgate lock further comprises a flip cover 40, which is rotatably connected to the vehicle body to cover the lock catch 20. Specifically, the lock catch 20 can be covered by the provided flip cover 40, thereby improving the aesthetics of the vehicle body after the tailgate is opened. The specific structure of the flip cover 40 can refer to the structure of existing products on the market, and is not limited here.
