Technical Field

[0001] This invention relates to the technical field of automotive exterior handles, and more specifically to an automotive exterior handle with a limiting structure. Background Technology

[0002] A car door handle limiting structure is a structure used to limit and control the range of movement or position of the handle. Its function is to ensure that when the car owner or passengers use the car door handle, they will not exceed the designed range of movement, thereby avoiding damage to the door handle system or other components, and ensuring the safety and smoothness of door operation.

[0003] The existing technology still has the following areas for improvement: The existing car handle limiting structure usually uses a claw to lock the handle frame by rotation to limit the amount of back and forth movement of the handle in the whole vehicle. This structure has low stability and is prone to loosening after long-term reciprocating use, causing the handle to fall off, affecting the normal opening and closing of the car door. The handle has low reliability and a poor user experience. Summary of the Invention

[0004] To address the aforementioned problems in the prior art, this invention provides an automotive external handle with a limiting structure, which enables the handle to be stably and securely installed in a preset position. The structures fit together tightly, preventing loosening and improving the reliability and feel of the handle.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0006] An automotive exterior handle with a limiting structure includes a body sheet metal, a handle, a limiting component, a transmission component, and a locking component. The body sheet metal has a through hole, 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 component.

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

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

[0009] The locking assembly includes a fixing block and a door lock cylinder. The fixing block is fixedly connected to the inner side of the base, and the door lock cylinder is fixedly connected to the fixing block.

[0010] Preferably, one side of the base is provided with a first buckle and two sets of symmetrically arranged limiting grooves, and the other side of the base is provided with an installation groove.

[0011] Preferably, the locking clamp is provided with a groove, a second buckle, a locking slot, a pre-installed slot, and two sets of symmetrically arranged limiting blocks and limiting holes. The limiting blocks and the limiting slots are matched, and the locking slots are matched with the first buckle.

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

[0013] Preferably, the handle pin is matched with the limiting hole, and the handle pin is disposed at the limiting hole.

[0014] Preferably, the end of the glove with the protective sleeve is positioned in the mounting groove.

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

[0016] Preferably, the first connector is an integral upper and lower part, the upper part of the first connector is hook-shaped, the lower part of the first connector is cylindrical, and one end of the upper part of the first connector is located between the T-shaped horizontal section of the protective sleeve and the protruding block.

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

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

[0019] The beneficial effects of this invention are as follows:

[0020] (1) By setting limit components and transmission components, the technical effect that can be achieved is that the fixed block is fixedly connected to the inner side of the base, and the door lock cylinder is fixedly connected to the fixed block. It can mechanically unlock when the intelligent unlocking fails. The door opening and closing is controlled by the cooperation of the handle, the first connecting piece and the second connecting piece. When the handle is pulled to open or close the door, the first connecting piece is driven to rotate. The first connecting piece drives the second connecting piece to rotate, so that the unlocking mechanism unlocks and opens the door. The position of one end of the sensor corresponds to the position of the adjacent end of the first connecting piece, so that the sensor can detect the position of the handle movement by the change of the rotation position of the first connecting piece.

[0021] (2) By setting the locking component, the technical effect that can be achieved is that the limit block and the limit groove match, which makes it easy to limit and install the locking pliers. The locking slot matches the first buckle. By setting the pre-installation slot, the locking pliers can be pre-positioned and pre-installed on the base, saving the time required to adjust the position of the locking pliers when installing the handle later, and improving production efficiency. The locking slot cooperates with the first buckle to fix the locking pliers stably on the base, and is easy to disassemble and install, and easy to maintain.

[0022] (3) The T-section of the handle is fitted with a matching T-shaped protective sleeve, which can reduce the friction of the handle when pulling, making it smoother for the user to pull the handle, and reducing abnormal noise when pulling, thus improving the user's comfort. The handle pin is matched with the limit hole. The handle pin is set at the limit hole and is fixed between the locking clamp and the base by a pin to prevent the handle from coming out. The limit hole of the locking clamp and the base form a closed rotating cavity, allowing the handle pin to rotate freely in the cavity to achieve the closing and opening of the handle. The cooperation between the locking clamp and the base can ensure that the handle is stably and firmly installed in the preset position. The structure fits tightly and is not easy to loosen, improving the reliability and feel of the handle. Attached Figure Description

[0038] Reference Figures 1 to 10 The present invention discloses an external handle for automobiles with a limiting structure, including a body sheet 1, a handle 2, a limiting component, a transmission component and a locking component. The body sheet 1 is provided with a through hole, the handle 2 passes through the through hole of the body sheet 1, and the handle 2 is connected to the body sheet 1 through the limiting component.

[0039] The limiting component includes a base 3 and a locking clamp 4. The base 3 is fixedly connected to the body sheet metal 1, and the locking clamp 4 is located inside the base 3.

[0040] The transmission assembly includes a first connector 8, a spring 9, a sensor 10, and a second connector 11. The first connector 8 is rotatably connected to the base 3, the spring 9 is sleeved on the first connector 8, the second connector 11 is rotatably connected to the first connector 8, one end of the second connector 11 is connected to an unlocking mechanism, and the other end of the second connector 11 is connected to a car door unlocking mechanism. The sensor 10 is fixedly connected to the base 3.

[0041] The locking assembly includes a fixing block 6 and a door lock cylinder 7. The fixing block 6 is fixedly connected to the inside of the base 3, and the door lock cylinder 7 is fixedly connected to the fixing block 6, enabling mechanical unlocking when the smart unlocking fails.

[0042] Reference Figures 6 to 10 The base 3 has a first buckle 301 and two sets of symmetrically arranged limiting grooves 303 on one side, and an installation groove 302 on the other side. The locking clamp 4 has a groove 401, a second buckle 402, a locking groove 405, a pre-installation groove 406, and two sets of symmetrically arranged limiting blocks 403 and limiting holes 404. The limiting blocks 403 and the limiting grooves 303 match each other to facilitate the limiting and installation of the locking clamp 4. The locking groove 405 matches the first buckle 301. By setting the pre-installation groove 406, the locking clamp 4 can be pre-positioned and pre-installed on the base 3, saving the time required to adjust the position of the locking clamp 4 when installing the handle 2 later, and improving production efficiency. The locking groove 405 cooperates with the first buckle 301 to stably fix the locking clamp 4 on the base 3, and is easy to disassemble and maintain.

[0043] Reference Figures 1 to 7 One end of the handle 2 is provided with a handle pin 201, and the other end of the handle 2 is T-shaped. The T-shaped section of the handle 2 is fitted with a matching T-shaped protective sleeve 5, which can reduce the friction of the handle 2 when pulled, making it smoother for the user to pull the handle 2, reducing abnormal noise when pulling, and improving the user's comfort. The handle pin 201 matches the limiting hole 404. The handle pin 201 is set at the limiting hole 404 and is fixed between the locking clamp 4 and the base 3 by a pin. To prevent the handle 2 from coming off, the limiting hole 404 of the locking clamp 4 and the base 3 form a closed rotating cavity, allowing the handle pin 201 to rotate freely within the cavity, thus enabling the handle 2 to be closed and opened. The cooperation between the locking clamp 4 and the base 3 enables the handle 2 to be stably and firmly installed in the preset position. The structures fit tightly together, making it less prone to loosening, thus improving the reliability and feel of the handle. One end of the handle 2 covered with the protective sleeve 5 is located at the mounting groove 302. A protruding block 501 is provided on one side of the protective sleeve 5.
