Description

Technical Field

[0001] The invention relates to the technical field of automobile exterior handles, and in particular to an automobile exterior handle with a limiting structure. Background Art

[0002] The automobile handle limit structure refers to a structure used to limit and control the movement range or usage position of the handle. Its function is to ensure that the owner or passenger does not exceed the designed movement range when using the automobile door handle, thereby avoiding damage to the door handle system or other components, and ensuring the safety and smoothness of the door operation.

[0003] The current existing technology still has the following areas for improvement: the existing automobile handle limit structure usually uses a claw to lock the handle frame by rotation to limit the forward and backward swing of the handle in the vehicle. This structure has low stability and is prone to loosening after the handle is pulled back and forth for a long time, causing the handle to fall off, affecting the normal opening and closing of the car door. The handle has low reliability and a low user experience. Summary of the invention

[0004] In order to solve the above problems existing in the prior art, the present invention provides an automobile outer handle with a limiting structure, which can achieve stable and firm installation of the handle at a preset position. The structures fit tightly and are not easy to loosen, thereby improving the reliability and texture of the handle.

[0005] The purpose of the present invention can be achieved through the following technical solutions:

[0006] An automobile exterior handle with a limiting structure comprises a body sheet metal, a handle, a limiting assembly, a transmission assembly and a locking assembly, wherein a through hole is provided on the body sheet metal, the handle passes through the through hole of the body sheet metal, and the handle is connected to the body sheet metal through the limiting assembly;

[0007] The limiting assembly includes a base and a locking clamp, wherein the base is fixedly connected to the body sheet metal, and the locking clamp is arranged on the inner side of the base;

[0008] The transmission assembly includes a first connecting member, a spring, a sensor, and a second connecting member, wherein the first connecting member is rotatably connected to the base, the spring is sleeved on the first connecting member, the second connecting member is rotatably connected to the first connecting member, one end of the second connecting member is connected to an unlocking mechanism, and the sensor is fixedly connected to the base;

[0009] The locking assembly comprises a fixed block and a door lock core, wherein the fixed block is fixedly connected to the inner side of the base, and the door lock core is fixedly connected to the fixed block.

[0010] Preferably, a first buckle and two groups of symmetrically arranged limiting grooves are provided on one side of the base, and a mounting groove is provided on the other side of the base.

[0011] Preferably, the locking pliers are provided with a groove, a second buckle, a locking slot, a pre-installed slot and two groups of symmetrically arranged limit blocks and limit holes, the limit blocks match the limit slots, and the locking slot matches the first buckle.

[0012] Preferably, a handle pin is provided at one end of the handle, and the other end of the handle is arranged in a T-shape, and the T-shaped section of the handle is provided with a matching T-shaped protective sleeve.

[0013] Preferably, the handle pin matches the limiting hole, and the handle pin is arranged at the limiting hole.

[0014] Preferably, the handle cover is provided with one end of the protective cover arranged at the mounting groove.

[0015] Preferably, a protruding block is provided on one side of the protective cover.

[0017] Preferably, a circular hole is provided at the other end of the upper half of the first connecting member, and the second connecting member is located at the circular hole of the first connecting member.

[0018] Preferably, the position of one end of the sensor corresponds to the position of the first connecting member at an adjacent end.

[0019] The beneficial effects of the present invention are:

[0020] (1) By setting a limit assembly and a transmission assembly, the technical effect that can be achieved is that the fixed block is fixedly connected to the inner side of the base, the door lock cylinder is fixedly connected to the fixed block, and mechanical unlocking can be performed when the intelligent unlocking fails. The door switch is controlled by the cooperation of the handle, the first connecting member, and the second connecting member. When the handle is pulled to open or close the door, the first connecting member is driven to rotate, and the first connecting member drives the second connecting member to rotate so that the unlocking mechanism is unlocked to open the door. The position of one end of the sensor corresponds to the position of the first connecting member at the adjacent end, so that the sensor can detect the position of the handle movement through the change of the rotation position of the first connecting member.

[0021] (2) By setting the locking component, the technical effect that can be achieved is that the limit block and the limit slot are matched, which is convenient for limiting and installing the locking pliers. The locking card slot matches the first buckle. By setting the pre-installed card slot, the locking pliers can be pre-positioned and pre-installed on the base, saving the time required for adjusting the position of the locking pliers when the handle is subsequently installed, thereby improving production efficiency. The locking card slot cooperates with the first buckle to stably fix the locking pliers on the base, and is convenient for disassembly and assembly, and easy for maintenance.

[0022] (3) The T-section sleeve of the handle is provided with a matching T-shaped protective sleeve, which can reduce the friction of the handle when it is pulled, making it smoother for the user to pull the handle, and reducing abnormal noise when pulling, thereby improving the user's comfort when using it. The handle pin shaft matches the limiting hole, and the handle pin shaft is arranged at the limiting hole. The handle pin shaft is fixed between the locking clamp and the base by means of a latch to prevent the handle from falling out. The limiting hole of the locking clamp and the base form a closed shaft rotation cavity, so that the handle pin shaft can rotate freely in the cavity to achieve the closing and opening of the handle. The cooperation between the locking clamp and the base can realize the stable and firm installation of the handle in the preset position. The structures are tightly matched and not easy to loosen, thereby improving the reliability and texture of the handle. BRIEF DESCRIPTION OF THE DRAWINGS
