Description

Technical Field

[0001] The utility model relates to the technical field of vehicle door locks, in particular to a vehicle and a tailgate lock installation structure thereof. Background Art

[0002] In order to cope with the development trend of the automotive industry towards electrification, automation and interconnection, a large number of pure electric vehicles on the market are currently equipped with more intelligent modules, through-type taillights and reinforced sound insulation glass. This has led to a significant increase in the weight of the car's tailgate, and the sealing reaction force of the tailgate system has also been greatly increased. This has posed severe challenges to technologies such as sealing strips, buffer blocks and support rod systems.

[0003] Due to the increase in sealing reaction force, the elastic potential energy stored in the tailgate and sealing strip system will increase significantly. At the moment the tailgate lock is unlocked, the elastic potential energy is released through the tailgate lock buckle, transmitted through the tailgate lock, and then converted into tailgate vibration and radiated noise, forming a very obvious unlocking noise, which seriously affects the overall quality of the vehicle.

[0004] Traditional noise reduction and vibration reduction technologies generally reduce impact noise by installing buffer blocks, rubber pads, rubber sleeves or vibration isolators on the lock body; or detect the contact pressure of the lock pin and the card through a strain spring sheet to control the rigid body vibration to suppress noise; or increase the rigidity of the lock structure to reduce vibration noise; or install a vibration isolation rubber layer specifically in the lock structure area to absorb vibration; or install rubber pads and adjust the rigid body mode of the tailgate to suppress road noise; or install a vibration sensor to obtain vibration information to resist the rigid body modal vibration caused by road excitation to suppress road noise; or obtain vehicle speed and tailgate status information and control the motor to drive the electric strut to resist the drum sound caused by road excitation.

[0005] In the above technologies, the buffer layer, rubber pads, vibration isolators and other components are all directly installed on the lock body, and there is still a rigid connection between the lock body or the lock installation area and the vehicle. Rigid collisions will still occur during vehicle operation or tailgate opening and closing, generating noise, and the vibration isolation and noise reduction effect is not significant; the vibration reduction structures such as electric struts, motor assistance, and sensor control are complex, costly, and the effect is not ideal.

[0042] The utility model also provides a vehicle in an embodiment, which includes a tailgate lock installation structure as described in any one of the above items.

[0043] The characteristics and functions of the present invention can be further understood through the following description.

[0044] A tailgate lock installation structure of the present embodiment is provided. Since pure electric vehicles are equipped with more intelligent modules, through-type taillights and reinforced soundproof glass in order to cope with the development trend of the electrification, automation and interconnection of the automobile industry, the weight of the automobile tailgate is greatly increased, the sealing reaction force of the tailgate system is greatly improved, and the elastic potential energy stored in the tailgate and sealing strip system is greatly increased. At the moment of unlocking, the elastic potential energy is released through the tailgate lock buckle, converted into tailgate vibration through the tailgate lock, and radiates noise, forming an unlocking noise problem that seriously affects the overall quality of the vehicle. Therefore, the utility model aims to solve the tailgate unlocking noise problem of such pure electric vehicles.

[0045] The tailgate lock installation structure of the utility model adopts a passive control method. Compared with the existing active control technology, it does not require data acquisition, servo mechanism and control unit. The tailgate lock installation structure has the advantages of simple structure, low cost and reliable use. The tailgate lock installation structure adopts a detachable structure. Compared with the existing technology, it can quickly meet the needs of various vehicle models through the universal design of flexible connecting parts, and has higher universal performance advantages. The tailgate lock installation structure does not need to use the vulcanization process and has a lower cost. The tailgate lock installation structure is designed with a positioning bolt hole, which can effectively reduce the risk of torque attenuation of the installation bolt.

[0046] The principle and function of the tailgate lock installation structure of the utility model are described as follows:

[0047] The tailgate lock (not shown) is mounted on the tailgate lock mounting plate 1. The flexible connector 10 composed of the mounting sleeve 2, the vibration isolation pad 3 and the vibration isolation sleeve 4 is mounted in the mounting holes 11 at both ends of the tailgate lock mounting plate 1. Bolts are used in the mounting sleeve 2 to mount the tailgate lock system on the mounting point. The upper end of the mounting sleeve 2 is designed with a positioning bolt hole 23 with a conical surface (such as Figure 2 During installation, first put the vibration isolation gasket 3 on the installation sleeve 2, then pass the vibration isolation sleeve 4 from bottom to top through the installation hole 11 of the tailgate lock installation plate 1, and finally pass the installation sleeve 2 and the vibration isolation gasket 3 together into the vibration isolation sleeve 4 from top to bottom.

[0048] After the tailgate is closed, the flexible connector 10 composed of the mounting sleeve 2, the vibration isolation gasket 3 and the vibration isolation sleeve 4 can separate the rigid connection between the tailgate lock mounting plate 1 connected to the tailgate and the mounting point bolts to form a flexible connection, thereby reducing the sealing reaction force when the tailgate is closed and reducing the elastic potential energy reserve when the tailgate is closed. When the tailgate is unlocked, the conversion of the elastic potential energy to the tailgate vibration through the tailgate lock is reduced, thereby reducing the unlocking noise.

[0049] The mounting sleeve 2 is made of metal, and serves to guide, position, and prevent torque failure of the bolts. The vibration isolation gasket 3 and the vibration isolation sleeve 4 can be made of rubber or wire mesh. The vibration isolation gasket 3 and the vibration isolation sleeve 4 are detachable universal parts, and can be designed with different hardness and stiffness according to different vehicle models.

[0050] In summary, the vehicle and its tailgate lock installation structure provided by the utility model enable the tailgate lock installation plate to be flexibly connected to the vehicle through a flexible connector, thereby reducing the reserve of elastic potential energy of the tailgate and the sealing system, thereby reducing the conversion of elastic potential energy to tailgate vibration through the tailgate lock at the moment of unlocking the tailgate lock, and solving the unlocking noise problem. The flexible connector of the utility model is a universal design that can be quickly adapted to various vehicle models. Flexible connectors of different sizes can be selected according to different vehicle models. The flexible connector can reduce the wear of the tailgate sealing strip by reducing the sealing reaction force of the tailgate, and extend the service life of the tailgate sealing strip. At the same time, the good positioning design function of the flexible connector can effectively ensure the sealing performance of the tailgate system.

[0051] The above is only a specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
