Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology, specifically relating to an automotive door handle. Background Technology

[0002] Door handles are mechanical devices in automobiles used for opening and closing doors. They achieve the door opening and closing function through a mechanical connection with the door lock opening arm. Currently, many door handle locks on the market have drawbacks such as inconvenient unlocking, complex locking and unlocking actions, and difficulty in operation. Utility Model Content

[0003] The purpose of this invention is to provide a car door handle that is simple in structure and easy to operate.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A car door handle includes a handle, a lock cylinder, a swing arm, a screw assembly, and a swing arm return spring. The lock cylinder has a lock spring assembly inside, and a lock cylinder limiting sleeve is provided at the bottom of the lock spring assembly. When a matching key is inserted and rotated at a certain angle, the bottom of the lock spring assembly can be inserted into the lock cylinder limiting sleeve. The screw assembly push rod passes through the inside of the lock cylinder limiting sleeve. After the lock spring assembly is pressed, it is inserted into the lock cylinder limiting sleeve and pushes the push rod downward. At this time, the moving end at the end of the screw assembly abuts against the door lock opening arm. The door lock is opened by rotating the door lock opening arm.

[0006] As a preferred technical solution of this utility model, a lock cylinder return spring is provided on the outer side of the lock cylinder internal lock spring assembly. When the downward pressing force of the lock spring assembly is eliminated, the lock spring assembly returns to its initial position under the action of the lock cylinder return spring.

[0007] As a preferred technical solution of this utility model, the swing arm is installed below the lock cylinder through a swing arm mounting bracket. When the matching key is inserted and rotated at a certain angle, the swing arm rotates at a certain angle together with the lock spring assembly and the lock cylinder limiting sleeve. At the same time, a swing arm return spring is installed above the swing arm. Through the elastic force of the swing arm return spring, the initial position of the swing arm and the lock cylinder limiting sleeve is returned to the correct position. At this time, when the lock spring assembly is subjected to downward pressing force, it cannot be inserted into the lock cylinder limiting sleeve, thereby locking the car door.

[0008] As a preferred technical solution of this utility model, when unlocking is required, the matching key is inserted and rotated in the opposite direction by a certain angle. The lock spring assembly drives the lock cylinder limiting sleeve and the swing arm to rotate together. At this time, the lock spring assembly can be inserted into the lock cylinder limiting sleeve again. Through the elastic force of the swing arm return spring, the swing arm position is returned to the correct position again. When the lock spring assembly is subjected to downward pressing force, it can be inserted into the lock cylinder limiting sleeve. When the lock spring assembly is subjected to downward pressing force, it drives the moving end of the screw assembly to abut against the door lock opening arm, thereby opening the car door lock.

[0009] As a preferred technical solution of this utility model, after the door lock is opened, the door lock opening arm returns to its initial position under the action of its return spring. At this time, the moving end of the screw assembly is squeezed again, pushing the push rod to enter the lock cylinder limiting sleeve again.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] The car door handle proposed in this utility model allows the door to be opened by pressing the lock cylinder, and to be locked and unlocked by rotating the key, which drives the swing arm. Furthermore, the up-and-down movement of the lock cylinder and the rotational movement of the swing arm do not interfere with each other. This structural design is novel and has high market application prospects. Attached Figure Description

[0021] The present invention will be further described in detail below with reference to the embodiments and accompanying drawings.

[0022] like Figure 1-7 As shown, the automobile door handle proposed in this utility model mainly includes: a handle 1, a lock cylinder 2, a swing arm 3, a swing arm mounting bracket 4, a screw assembly 5, a swing arm return spring 6, a lock cylinder return spring 7, a moving end 8, a lock cylinder limiting sleeve 10, a push rod 11, and a lock spring assembly 12. The handle 1 is installed on the outer door of the vehicle, and the lock cylinder 2 is installed on one side of the handle. The lock cylinder 2 is used to realize the opening and locking actions of the door.

[0023] The lock cylinder 2 has a lock spring assembly 12 inside. A lock cylinder limiting sleeve 10 is located at the bottom of the lock spring assembly 12. When the matching key is inserted and rotated a certain angle, the bottom of the lock spring assembly 12 can be inserted into the lock cylinder limiting sleeve 10. A push rod 11 of the screw assembly 5 passes through the inside of the lock cylinder limiting sleeve 10. After the lock spring assembly 12 is pressed, it inserts into the lock cylinder limiting sleeve 10 and pushes the push rod 11 downwards. At this time, the moving end 8 at the end of the screw assembly 5 abuts against the door lock opening arm 9. The door lock is opened by rotating the door lock opening arm 9. When the downward pressure is released, the lock spring assembly 12 returns to its initial position under the action of the lock cylinder return spring 7.

[0024] A rotatable swing arm 3 is installed below the lock cylinder 2. The swing arm 3 is installed below the lock cylinder via a swing arm mounting bracket 4. When the matching key is inserted and rotated at a certain angle, the swing arm 3 rotates at a certain angle together with the lock spring assembly 12 and the lock cylinder limiting sleeve 10. At the same time, a swing arm return spring 6 is installed above the swing arm 3. Through the elastic force of the swing arm return spring 6, the swing arm 3 and the lock cylinder limiting sleeve 10 are returned to their initial positions. At this time, when the lock spring assembly 12 is subjected to downward pressing force, it cannot be inserted into the lock cylinder limiting sleeve 10, thus locking the car door.

[0025] When unlocking is required, insert the matching key and rotate it in the opposite direction at a certain angle. The lock spring assembly 12 drives the lock cylinder limiting sleeve 10 and the swing arm 3 to rotate together (the lock spring assembly 12 cannot be inserted into the lock cylinder limiting sleeve 10 before it is fully rotated. Only when the lock spring assembly 12 is inserted into the lock cylinder limiting sleeve 10 can the push rod 11 move downward by pressing down). At this time, the lock spring assembly 12 can be inserted into the lock cylinder limiting sleeve 10 again, and the swing arm 3 is returned to its original position by the elastic force of the swing arm return spring 6. At the same time, when the lock spring assembly 12 is subjected to downward pressure, it can be inserted into the lock cylinder limiting sleeve 10. When the lock spring assembly 12 is subjected to downward pressure, it drives the moving end 8 of the screw assembly 5 to abut against the door lock opening arm 9, thereby opening the car door lock.

[0026] After the door lock is opened, the door lock opening arm 9 returns to its initial position under the action of its return spring. At this time, the moving end 8 of the screw assembly 5 is squeezed again, pushing the push rod 11 to enter the lock cylinder limiting sleeve 10 again.
