Description

Semi-hidden automobile door handle structure

Technical Field

The utility model relates to an automobile decoration technical field especially relates to a semi-hidden car door handle structure.

Background

The automobile door handle is an external decoration component higher than an automobile door metal plate, and the handle can be directly pulled to unlock the door during operation. It is generally composed of a plurality of parts, such as a handle, a cover, a bracket, a spring, a transmission member, a counter weight (the part of the weight is dead weight and only generates enough inertia force to prevent the handle from moving in case of collision), a sealing member, a fastening member, etc.

Hidden handles are a trend of door handle assemblies popular in recent years and are commonly used in new energy vehicles. The vehicle door metal plate is taken in at ordinary times and can be popped up when needed, so that the air resistance of the whole vehicle is favorably reduced, and the vehicle door metal plate is more attractive. However, the assembly has the problems of numerous parts, complex system, high cost, complex installation operation and the like.

Still another semi-concealed door handle is provided which has a low cost and simple installation and operation. The common structural characteristics of the semi-hidden vehicle door handle are as follows:

1. the handle is arranged on the vehicle door metal plate, and the inside of the handle is connected with a transmission mechanism such as a pull wire or a pull rod;

2. the handle is basically flush with the vehicle door metal plate, and an operation space is reserved below the handle;

3. the handle is turned upwards and lifted, and when the handle is lifted, the handle drives the transmission mechanism to unlock;

4. part of highly configured vehicle types have two sets of electronic and mechanical unlocking mechanisms, PCBA electronic devices integrated with micro switches are arranged in the handles, a cover plate capable of moving in a small range is additionally arranged on the inner side of an operation area, and the micro switches are arranged below the cover plate; the micro switch is connected with the E-latch electronic lock. Normally, only the electronic system is required to work: when a user pulls the handle, the movable cover plate starts to move firstly and drives the microswitch to generate a signal to unlock the E-latch electronic lock; when the electronic system cannot work (such as power shortage or failure), the mechanical mechanism can be directly adopted for unlocking: namely, the handle is pulled directly, and the pull wire or the pull rod is driven by the handle to unlock.

However, there are several problems with such handles:

1. the outward-lifting type handle has certain requirements on the shape of a vehicle door metal plate to prevent movement interference;

2. the microswitch and the PCBA electronic device are integrated, so that glue can not be poured and sealed, a higher-cost mode is needed for sealing, and the problem of low-temperature failure exists;

3. the manufacturability of the part is poor, and the bowl-shaped plastic part is easy to shrink and deform after injection molding, so that the problem of matching with a finished automobile is caused;

4. when the handle bracket is assembled with the side sheet metal, the handle bracket needs to move along the X direction, so that the handle bracket is difficult to accurately position;

5. the opening of the door metal plate on the handle is difficult to be completely sealed, and water and air leakage is easy to occur.

Detailed Description

Embodiment is as shown in fig. 1-6, the utility model discloses half hidden car door handle structure includes handle body 1 and handle lid 2, door sheet metal component inboard is located to handle body 1 to connect door mechanical lock through acting as go-between or pull rod, handle lid 2 is located the door sheet metal component outside and is covered handle body 1 still includes apron 4, pivot 5, reset spring 6, micro-gap switch 7 and the PCBA electron device 8 that is equipped with unblock induction zone and shutting induction zone, handle body 1 is gone up along being equipped with horizontal elongated slot 11, apron 4 is located penetrate along both sides in the handle body 1 and on the pivot 5, pivot 5 is located in the horizontal elongated slot 11, reset spring 6 locates 5 both ends of pivot and support and lean on extremely between apron 4 and the handle body 1, handle body 1 rotates to support and lean on apron 4 winds pivot 5 upset, handle body 1 resets after, apron 4 resets under reset spring 6's effect, handle body 1 is in apron 4 one side is equipped with the installation hole site and locates micro-gap switch 7 is located the handle body contact of apron 1, the handle body is located the handle body 7 is located the handle body contacts of the electricity switch contacts 8 and the electricity is located the switch contacts of the switch.

Preferably, the handle body 1 is flush with the outer side of the vehicle door sheet metal part, and the vehicle door sheet metal part is arranged below the handle body 1 to form an operation space through stamping.

Preferably, reinforcing blocks 41 are arranged on two sides of the upper edge of the cover plate 4, the reinforcing blocks 41 are provided with transverse through holes 42, and the rotating shaft 5 penetrates through the transverse through holes 42 of the reinforcing blocks 41.

Preferably, the PCBA electronics 8 is connected to the door electronic lock via a wire harness and a connector.

In the door handle structure, a handle body contains PCBA electronic devices, a microswitch, a reset spring of a cover plate, a wiring harness, a plug-in connector and other parts; the micro switch is positioned in the anti-pinch structure area of the handle body, and a button contact of the micro switch is contacted with the cover plate; when the handle body is operated, the cover plate rotates around the rotating shaft in a small amplitude, the button contact of the microswitch is pushed to switch on a signal, and the switching on signal is transmitted to the E-latch electronic lock to realize electronic unlocking. When the cover plate continues to rotate to the maximum position, one end of the cover plate, which is far away from the rotating shaft, is in contact limit with the handle body, and the cover plate is in a static stress state. After the handle body is loosened, the cover plate rebounds to the initial position under the action of the reset spring, and the micro switch disconnects the signal.

When the rotation operating force of the handle body is large, the handle body is pulled vigorously to unlock the handle body only when the electric function fails. When the electric function is normal, only pull handle body with less power, only have the apron to rotate at this moment and arouse micro-gap switch, produce signal to door electronic lock, realize the unblock. After the door is unlocked, the handle body is continuously pulled to open the door, the pulling force at the moment is only the force for driving the door to open, and the force is smaller than the opening force for mechanically unlocking by rotating the handle body.

The inner side of the PCBA electronic device is an unlocking induction area, the tail end of the outer side of the PCBA electronic device is a locking induction area, and related functions can be completed by touching the corresponding area. The handle body can realize two functions of mechanical unlocking and electronic unlocking, and the microswitch and the PCBA electronic device are respectively assembled, so that independent sealing can be realized, the sealing performance of the whole structure is improved, and the process difficulty and the cost are reduced; meanwhile, the micro switch is innovatively arranged by utilizing the framework space of the hand clamping prevention area of the handle body, so that the thickness of the handle body and the space occupied by the whole structure are reduced, and the manufacturing cost is saved.
