Due to the force operation during installation, the shape or structure of the handle body along the X direction cannot be hindered, that is, the anti-pinch hand area of the handle must be very small. Otherwise, more parts need to be added to complete the assembly, which is high in cost.

[0005] 2. The appearance treatment of the handle of the vehicle is limited. The X direction pulling is easy to scratch the surface of the anti-pinch hand structure of the handle, so the anti-pinch hand area cannot be treated by spraying paint or electroplating, but only can be treated by surface texture processing with the original color of the material.

[0006] 3. It is not suitable for an integrated handle, that is, the handle and the cover are combined together. The cover area of the original handle is easy to scratch the paint surface of the door panel during assembly.

[0007] 4. The rotating rod is directly opposite to the handle in the X direction, and the handle recess of the door panel, the handle body and the rotating rod are at the same height in the Z direction, which occupies more space in the Y direction, resulting in a large thickness of the door.

[0026] The rod body of the rotating rod 5 is provided with a semicircular disc 51, a special-shaped protrusion 52 is arranged on one side of the top surface of the semicircular disc 51, a limiting baffle 53 is arranged on the other side along the thickness direction of the semicircular disc 51, an arc-shaped protrusion 54 is arranged on the outer circle of the rod body of the rotating rod 5 along the axial direction, and a protrusion 55 is arranged on the outer circular arc surface of the arc-shaped protrusion 54; the clamping piece 7 comprises spaced upper and lower legs 72 and 73, the adjacent surfaces of the upper and lower legs 72 and 73 are provided with a notch 74, and the lower leg 73 is provided with a protruding part 75, the bracket 1 is provided with a limiting baffle 13 on one side of the pin hole 12, and a first sliding groove 14 and a second sliding groove 15 are sequentially and spaced arranged in the lower part of the pin hole 12;

[0027] When the rotating rod 5 is fitted into the pin hole 12 through the pin shaft 8, the semicircular disc 51 of the rotating rod 5 is located in the first sliding groove 14 of the bracket 1, the arc-shaped protrusion 54 is located in the second sliding groove 15 of the bracket 1, and the protrusion 55 on the outer circular arc surface of the arc-shaped protrusion 54 is abutted to the notch of the second sliding groove 15 of the bracket 1, the protruding part 75 of the lower leg 73 of the clamping piece 7 is abutted to the limiting baffle 53 of the semicircular disc 51, and the two jointly limit the rotation of the rotating rod 5 around the pin shaft 8; at this time, the handle body 2 and the cover 3 are clamped into the bracket 1 through the notch 74 between the upper and lower legs 72 and 73 of the clamping piece 7; in this state, the spring 9 is in the maximum torque and is compressed in the axial direction by the rotating rod 5, that is, the spring 9 simultaneously realizes the functions of a torsional spring and a compression spring, and the torque and the pressure are both maximum;

[0028] When the assembly fastening bolt 71 is screwed, the clamp 7 moves outward in the bracket slot 11, the protrusion 75 of the lower leg 73 of the clamp 7 is out of contact with the limiting baffle 53 of the semicircular disc 51, the convex 55 of the outer arc surface of the arc-shaped block 54 is out of the slot of the second sliding groove 15 of the bracket 1, and the rotary lever 5 rotates to the side 57 of the semicircular disc 51 under the action of the torque of the spring 9 and abuts against the limiting baffle 13 on one side of the pin hole 12 of the bracket 1; at this time, the rotary lever 5 moves along the axial direction to the side of the hook 22 of the handle body 2 (i.e. the working position of the rotary lever) under the action of the elasticity of the spring 9, the side 57 of the semicircular disc 51 of the rotary lever 5 is out of contact with the limiting baffle 13 on one side of the pin hole 12 of the bracket 1, the semicircular disc 51 falls into the first sliding groove 14 and limits the rotary lever in the Z-axis direction, the limiting baffle 53 of the semicircular disc 51 of the rotary lever 5 is out of position with the protrusion 75 of the lower leg 73 of the clamp 7 in the Z-axis direction, when the protrusion 75 of the clamp 7 is out of the range of the rotary radius of the rotary lever 5, it is no longer limited and there is no movement interference or limitation, and the rotary lever 5 rotates under the action of the torque of the spring 9 so that the arc-shaped block 54 of the rotary lever 5 is connected with the hook 22 of the handle body 2. The first sliding groove 14 ensures that the rotary lever 5 rotates without interference, and on the other hand, the width of the first sliding groove 14 also limits the rotary lever in the Z direction, so that the rotary lever 5 cannot be separated from the hook of the handle body in the Z direction.

[0029] Preferably, after the arc-shaped block 54 of the rotary lever 5 is connected with the hook 22 of the handle body 2, the assembly fastening bolt 71 is screwed to move the clamp 7 inward in the bracket slot 11, so that the slot 74 of the adjacent surface of the upper leg 72 and the lower leg 73 of the clamp 7 clamps and fixes the lock block 4 or the false shell, and the free ends of the upper leg 72 and the lower leg 73 of the clamp 7 are located in the movement track of the handle body 2, and when the handle body 2 is pulled to the maximum opening position, the protrusion 75 of the lower leg 73 of the clamp 7 limits the maximum opening position of the handle body 2.

[0030] Preferably, the limiting baffle 53 in the thickness direction of the semicircular disc 51 of the rotary lever 5 is provided with a through hole 56, and the lock block 4 or the false shell is connected with the through hole 56 through a pull wire or a pull rod.

[0031] The structure enables the handle to be assembled without moving in the X direction, the rotary lever avoids the installation space of the handle in the Z direction when the bracket is not assembled with the handle body, so that the handle body and the cover can be freely assembled in the Y direction without being pulled in the X direction. When the handle body is installed to the correct position of the bracket, the clamp is pulled to unlock the rotary lever, the rotary lever can be automatically inserted into the hook of the handle body in the Z direction under the joint action of the rotary lever itself, the bracket structure and the spring, the handle body is pulled, the rotary lever is driven through the hook, the rotary lever drives the lock block through the pull wire or the pull rod, and the door is opened.

[0032] The rotary rod of the structure can realize segmented multi-state floating movement in the support. The hook of the rotary rod and the handle body and the door panel handle pocket area are located at different heights in the Z direction, forming a height staggered layout. The hook of the handle body, the door panel handle pocket and the rotary rod of the traditional door handle structure are usually at the same height in the Z direction, which leads to complex assembly and other disadvantages. The rotary rod of the structure can move within a certain range in the Z direction. Under the action of the support, the clamp, the spring and the special structure of the rotary rod itself, the rotary rod can be positioned at the two extreme positions in the Z direction, achieving the purpose of simplifying the installation process.

[0033] The structure does not change the number of parts of the traditional door handle structure. The handle body can complete the assembly of the door handle structure without pulling in the X direction. The problem of limited anti-pinch area of the traditional door handle structure and the problem of limited assembly of the integrated handle are solved. The rotary rod of the structure avoids the position of the door panel handle pocket, so that the rotary rod can be arranged more outward in the Y direction. The space occupied by the support is reduced, the Y direction size of the door can be further reduced, and the overall appearance and application performance of the automobile handle are improved.
