Description

Technical Field

[0001] The utility model relates to the technical field of automobiles, and more specifically, to an in-vehicle door handle. Background Art

[0002] Automobiles are one of the very important means of transportation in modern life. Generally composed of four basic parts: an engine, a chassis, a body, and electrical equipment, they have the advantage of facilitating people's travel. Existing car doors generally integrate an in-handle assembled on the inner side of the door and an out-handle assembled on the outer side of the door. Both the in-handle and the out-handle are connected to the lock body assembly inside the door, and when the in-handle / out-handle is pulled, the lock body can be controlled by a wire to lock / unlock, thus ensuring that passengers and drivers can freely enter and exit the carriage.

[0003] Existing in-handles generally include a mounting base, a handle, and a connecting shaft. The mounting base is embedded in the interior trim panel of the door and locked by fasteners. The handle is hinged to the mounting base through the connecting shaft and connected to the lock body assembly through a wire. An elastic reset member is installed between the mounting base and the handle. The user can pull the handle, causing the handle to rotate around the connecting shaft and pull the wire, thereby unlocking the lock body assembly. After unlocking, the elastic reset member can pull the handle to rotate back to its original position, ensuring the normal operation of the in-vehicle door handle.

A spring for pressing the pressing plate 301 to rebound is connected to the spring connection buckle 103, and the photoelectric sensor 104 is connected to the vehicle control device, which can play a proximity detection function during the pressing process of the pressing plate 301. The sliding groove 105 is used for the sliding block of the driving structure 5 to be limited and slide.

[0028] The handle structure 2 includes an in-vehicle door handle 201, a pulling buckle 202, a first ear 203, a connecting rod 204, a pulling groove 205, and a pulling rod 206. A pulling buckle 202 is fixedly arranged on the in-vehicle door handle 201, a pulling groove 205 is opened on the pulling buckle 202, the pulling groove 205 is connected to a pulling rod 206, first ears 203 are fixedly arranged on both sides of the in-vehicle door handle 201, a connecting rod 204 is arranged on one side of the first ear 203, and the connecting rod 204 is fixedly installed on the in-vehicle door handle 201. The first ear 203 of the handle structure 2 is rotatably connected to the first damping groove 403. During the rotation of the in-vehicle door handle 201 on the rotating shaft structure 4, the pulling groove 205 of the pulling buckle 202 will drive the pulling rod 206 to move. The pulling rod 206 is connected to the control cable, and the door is unlocked through the cooperation of the control assembly. The connecting rod 204 is connected to one end of the second spring 604, so that it can automatically rebound after the in-vehicle door handle 201 is pulled open.

One end of the first spring 603 is connected with a connecting sleeve 605, and the connecting sleeve 605 is fixedly sleeved in the docking groove 402. The driving motor 501 of the driving structure 5 drives the threaded rod 504 to rotate through the transmission of the first bevel gear 502 and the second bevel gear 503. The threaded rod 504 drives the threaded transmission block 505 and the push rod 506 to move. The push rod 506 moves directionally under the restriction of the sliding blocks and the sliding groove 105, driving the fixed sleeve of the resistance structure 6 to adjust its position. By adjusting the position of the fixed sleeve, the elastic forces of the first spring 603 and the second spring 604 can be adjusted, so that the resilience force can be adjusted.

[0032] To facilitate the understanding of the above technical solution of the present utility model, the working principle or operation mode of the present utility model in the actual process will be described in detail below.

[0033] The installation shell 101 of the bottom shell structure 1 is generally installed on the inner side of the car door. A spring is connected to the spring connection buckle 103 for pressing the pressing plate 301 to rebound. The photoelectric sensor 104 is connected to the vehicle control device and can perform proximity detection during the pressing process of the pressing plate 301. The sliding groove 105 is used to limit the sliding of the sliding block of the driving structure 5. The first ear 203 of the handle structure 2 is rotatably connected to the first damping groove 403. When the inner handle 201 rotates on the rotating shaft structure 4, the pulling groove 205 of the pulling buckle 202 will drive the pulling rod 206 to act. The pulling rod 206 is connected to the control cable, and the car door is unlocked through the cooperation of the control assembly. The connecting rod 204 is connected to one end of the second spring 604, so that it can automatically rebound after the inner handle 201 is pulled open. The pressing plate 301 is correspondingly connected to the second damping groove 404 of the rotating shaft rod 401 through the second ear 302. The first adjusting airbag 405 and the second adjusting airbag 406 of the rotating shaft structure 4 are filled with gas. Both sides of the adjusting airbag are connected with electromagnets, and the electromagnets are connected to the vehicle control assembly. The suction force of the electromagnets on both sides of the adjusting airbag can be controlled by controlling the magnetism of the electromagnets. When the suction force of the two electromagnets increases, the adjusting airbag will be compressed, causing the middle part of the airbag to expand. The surface of the adjusting airbag is made of a friction material, which will increase the rotational resistance with the first ear 203 and the second ear 302. The driving structure 5 and the resistance structure 6 can cooperate to adjust and control the resilience, thereby realizing the adjustment of the damping force. The damping can be adjusted according to actual needs. The driving motor 501 of the driving structure 5 drives the threaded rod 504 to rotate through the transmission of the first bevel gear 502 and the second bevel gear 503. The threaded rod 504 drives the threaded transmission block 505 and the push rod 506 to transmit. The push rod 506 moves directionally under the restriction of the sliding block and the sliding groove 105, driving the fixed sleeve of the resistance structure 6 to adjust its position. By adjusting the position of the fixed sleeve, the elasticity of the first spring 603 and the second spring 604 can be adjusted, so that the resilience can be adjusted.

[0034] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
