Description

Technical Field

[0001] This utility model relates to the field of vehicle-related technology, and in particular to an external door handle and a door. Background Technology

[0002] Some existing vehicle models use concealed external handles. However, concealed external handles are inconvenient to operate in cold environments, and pose a safety hazard in emergency situations.

[0003] To address this, existing technologies have proposed semi-concealed external handles. Semi-concealed external handles balance the need for a smooth vehicle appearance with customer considerations for ease of operation and safety, and are showing a trend towards wider application.

[0004] The existing semi-recessed door handles are installed from the outside of the vehicle towards the inside. The sheet metal has two mounting holes formed at both ends of the handle for bolt fixing. The door handle is connected to the door lock outwards via a lever. At the same time, the position of the door handle must be higher than the door lock (in the vehicle height direction) to form the unlocking movement of pressing down on the lever.

[0005] Existing semi-concealed external handles use mechanical or electronic controls to operate the door lock. However, electronic controls have certain risks of failure, especially in the event of a collision, making mechanical controls more reliable.

[0006] However, existing semi-concealed mechanical control external handles are linked to the door lock linkage. The door lock is unlocked by pressing down on the door lock linkage. However, if the external handle is positioned at the same height as the door lock, or if the external handle is higher than the door lock, the door lock linkage cannot work. This results in a fixed relative position between the door lock and the external handle, limiting the placement and selection of the handle. Utility Model Content

[0046] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0047] like Figure 1The diagram shows a structural schematic of an exterior door handle according to an embodiment of the present invention. It includes an exterior handle assembly 2 mounted on a door sheet metal 1 and an outward-opening pull cable 3 connected to the exterior handle assembly 2. The exterior handle assembly 2 includes an exterior handle 21, a handle base 22, a handle shaft 23, a connecting rod 24, and a return torsion spring 25. The handle shaft 23 is inserted into the exterior handle 21 and is fixedly connected to the handle base 22. The return torsion spring 25 is sleeved on the handle shaft 23, with one end fixedly connected to the handle base 22 and the other end fixedly connected to the exterior handle 21. The exterior handle 21 includes gripping portions connected in sequence. 211, connecting part 213 and handle rotating arm 212, the handle rotating shaft 23 is inserted into the connecting part 213, the outward pull handle 21 can rotate around the handle rotating shaft 23, the back of the handle base 22 is fixedly connected to the connecting rod rotating shaft 221, the connecting rod rotating shaft 221 is inserted into the middle of the connecting rod 24, and the connecting rod rotating shaft 221 is fitted with a connecting rod return spring 27 connected to the connecting rod 24, the connecting rod 24 can rotate around the connecting rod rotating shaft 221, the upper rotating arm 241 of the connecting rod 24 contacts the handle rotating arm 212, the lower rotating arm 242 of the connecting rod 24 is connected to one end of the outward opening pull cable 3, and the other end of the outward opening pull cable 3 is connected to the lock body 4.

[0048] Specifically, the exterior door handle of this utility model is a semi-concealed exterior handle. Preferably, the exterior door handle of this utility model is an upward-opening exterior handle.

[0049] The outer handle assembly 2 is installed on the door sheet metal 1. The outer handle assembly 2 is connected to the lock body 4 through the outer opening pull cable 3. The outer handle assembly 2 pulls the lock body 4 through the outer opening pull cable 3 to unlock.

[0050] In one embodiment, the outward-opening pull cable 3 is connected to the lock body 4 via a connector 5.

[0051] Among them, such as Figures 2 to 4As shown, the external handle assembly 2 includes an external handle 21, a handle base 22, a handle shaft 23, a connecting rod 24, and a return torsion spring 25. The handle shaft 23 is inserted into the external handle 21 and is fixedly connected to the handle base 22. The return torsion spring 25 is sleeved on the handle shaft 23, with one end fixedly connected to the handle base 22 and the other end fixedly connected to the external handle 21. The external handle 21 includes a gripping part 211, a connecting part 213, and a handle arm 212 connected in sequence. The handle shaft 23 is inserted into the connecting part 213, allowing the external handle 21 to rotate around the handle shaft. 23 rotates, and the back of the handle base 22 is fixedly connected to the connecting rod shaft 221. The connecting rod shaft 221 is inserted into the middle of the connecting rod 24, and the connecting rod shaft 221 is fitted with a connecting rod return spring 27 connected to the connecting rod 24. The connecting rod 24 can rotate around the connecting rod shaft 221. The upper connecting arm 241 of the connecting rod 24 contacts the handle arm 212. The lower connecting arm 242 of the connecting rod 24 is connected to one end of the outward opening pull cable 3, and the other end of the outward opening pull cable 3 is connected to the lock body 4.

[0052] The connecting rod 24 adopts a seesaw structure: one end is the upper rotating arm 241 of the connecting rod, which contacts the outer pull handle 21, and the other end is the lower rotating arm 242 of the connecting rod, which is connected to one end of the outer pull cable 3. The connecting rod 24 rotates around the connecting rod shaft 221.

[0053] When the handle grip 211 is flipped upwards, the outer pull handle 21 rotates around the handle pivot 23. The handle arm 212 of the outer pull handle 21, located on the back of the handle base 22, contacts the upper arm 241 of the connecting rod, pushing the connecting rod 24 to rotate synchronously around the connecting rod pivot 221. Figure 5 and Figure 6 As shown, the outer pull handle 21 rotates around the handle pivot 23, having an open position and a closed position. The synchronously rotating connecting rod 24 also has an open position and a closed position.

[0054] The lower rotating arm 242 of the linkage is connected to the outward opening cable 3. When the outward pulling handle 21 is rotated to the open position, it pushes the linkage 24 to rotate to the open position of the linkage 24. When the displacement generated by the lower rotating arm 242 of the linkage and the outward opening cable 3 exceeds the door lock opening stroke, the outward pulling handle 21 reaches the open position. Similarly, the linkage 24 also reaches the open position, and the door opens.

[0055] During the rotation of the outer handle 21 to the open position, the return torsion spring 25 tightens. When the user releases the handle, the return torsion spring 25 relaxes and resets, returning the outer handle 21 to the closed position. At the same time, there is a connecting rod return spring 27 between the connecting rod 24 and the connecting rod shaft 221. One end of the connecting rod return spring 27 is fixedly connected to the handle base 22, and the other end is connected to the connecting rod 24. The connecting rod return spring 27 generates a preload force that returns the connecting rod 24 to the closed position.

[0056] Throughout the opening and closing process of the pull handle 21, under the force of the linkage return spring 27, the linkage 24 is always in contact with the handle arm 212.

[0057] In some embodiments, the lower pivot arm 242 of the connecting rod is provided with a ball-and-socket structure 2421, and the end of the outward-opening pull cable 3 is connected to the ball head structure 30, which is assembled inside the ball-and-socket structure 2421. When the connecting rod 24 rotates in the open position direction, the ball-and-socket structure 2421 of the lower pivot arm 242 drives the ball head structure 30 to move. When the displacement generated by the ball head exceeds the door lock opening stroke, the door opens.

[0058] The linkage 24 converts the up-and-down flipping motion of the handle into a linear motion of the outward pull cable 3 in the up-and-down or left-and-right directions. Therefore, the relative arrangement of the outward pull handle and the door lock in the up-and-down or front-and-back directions is relatively flexible.

[0059] The exterior door handle of this invention connects the outer pull handle to the upper end of a connecting rod, and the lower end of the connecting rod is connected to an outward-opening cable. This allows the upward rotation of the outer pull handle to be converted into a linear motion of the door lock's outward-opening cable. Therefore, the relative positional relationship between the door lock and the outer handle is relatively flexible, enabling more flexible arrangement and selection to meet different design requirements.

[0060] like Figures 1 to 12 As shown, another embodiment of this utility model provides an exterior door handle, comprising: an exterior handle assembly 2 mounted on a door sheet metal 1 and an outward-opening pull cable 3 connected to the exterior handle assembly 2. The exterior handle assembly 2 includes: an exterior handle 21, a handle base 22, a handle shaft 23, a connecting rod 24, and a return torsion spring 25. The handle shaft 23 is inserted into the exterior handle 21 and is fixedly connected to the handle base 22. The return torsion spring 25 is sleeved on the handle shaft 23, with one end fixedly connected to the handle base 22 and the other end fixedly connected to the exterior handle 21. The exterior handle 21 includes gripping portions 211 connected in sequence. The lock consists of a connecting part 213 and a handle rotating arm 212. The handle rotating shaft 23 is inserted into the connecting part 213, and the outward pull handle 21 can rotate around the handle rotating shaft 23. The back of the handle base 22 is fixedly connected to the connecting rod rotating shaft 221. The connecting rod rotating shaft 221 is inserted into the middle of the connecting rod 24, and a connecting rod return spring 27 connected to the connecting rod 24 is sleeved on the connecting rod rotating shaft 221. The connecting rod 24 can rotate around the connecting rod rotating shaft 221. The upper rotating arm 241 of the connecting rod 24 contacts the handle rotating arm 212. The lower rotating arm 242 of the connecting rod 24 is connected to one end of the outward pull cable 3, and the other end of the outward pull cable 3 is connected to the lock body 4.

[0061] A base block 222 is fixedly connected to the lower end of the back of the handle base 22, and a sliding groove 223 is fixedly connected below the base block 222. A slider 26 that can slide up and down along the sliding groove 223 is fitted on the sliding groove 223.

[0062] The slider 26 includes: a slider body 262, a slider spring 261 fixedly connected to the upper end of the slider body 262, and one or more fixing ribs 263 fixedly connected to the lower end of the slider body 262. The slider body 262 has a notch that mates with the slide groove 223. The slider body 262 is inserted into the slide groove 223 and can move up and down along the slide groove 223. The end of the slider spring 261 abuts against the base block 222, and the fixing ribs 263 partially extend out of the handle base 22.

[0063] The lower end of the fixing rib 263 is a guide slope 264, which slopes downward from away from the handle base 22 toward closer to the handle base 22;

[0064] The slider 26 also includes a limiting spring piece 265 fixedly connected to the lower end of the slider body 262, and a limiting block 224 is fixedly connected to the lower end of the back of the handle base 22, the limiting block 224 being located below the limiting spring piece 265.

[0065] The outward-opening pull cable 3 includes a first pull cable 31 and a second pull cable 32. The first end of the first pull cable 31 is connected to the lower rotating arm 242 of the connecting rod, the first end of the second pull cable 32 is connected to the lock body 4, and the second end of the first pull cable 31 is connected to the second end of the second pull cable 32 through a connector 5.

[0066] Specifically, in this embodiment, the door handle is a semi-concealed handle. The handle assembly 2 is installed on the door sheet metal 1. The handle assembly 2 is connected to the lock body 4 through the outward opening cable 3. The handle assembly 2 pulls the lock body 4 through the outward opening cable 3 to unlock.

[0067] The outer handle assembly 2 includes a connecting rod 24. The connecting rod 24 employs a seesaw structure, with one end's upper rotating arm 241 contacting the handle rotating arm 212, and the other end's lower rotating arm 242 connected to the outward-opening pull cable 3. The connecting rod 24 rotates around the connecting rod pivot 221. The outward-opening pull cable 3 includes a first pull cable 31 and a second pull cable 32, with the lower rotating arm 242 connected to the first end of the first pull cable 31.

[0068] When the handle grip 211 is flipped upwards, the outer handle 21 rotates around the handle pivot 23. Since the handle pivot 23 is inserted into the connecting part 213 between the grip 211 and the handle arm 212, when the grip 211 is flipped upwards, the handle arm 212 flips downwards, contacting the upper arm 241 of the connecting rod, thus pushing the connecting rod 24 to rotate synchronously around the connecting rod pivot 221. Figure 5 and Figure 6 As shown, the outer pull handle 21 rotates around the handle pivot 23, having an open position and a closed position. The synchronously rotating connecting rod 24 also has an open position and a closed position. The grip portion 211 is located in the closed position at the bottom and in the open position at the top. When the grip portion 211 is flipped upward, it flips from the closed position to the open position.

[0069] The lower rotating arm 242 of the linkage is connected to the outward opening cable 3. When the linkage 24 rotates, the lower rotating arm 242 drives the outward opening cable 3 to move. When the grip 211 reaches the open position, the displacement generated by the outward opening cable 3 exceeds the door lock opening stroke, and the door opens.

[0070] By reversing the linkage 24, the up-and-down flipping motion of the handle is converted into a linear motion of the outward pull cable 3 in the up-and-down or left-and-right directions; at the same time, the relative arrangement of the outward pull handle and the door lock in the up-and-down or front-and-back directions is relatively free.

[0071] In some embodiments, the lower pivot arm 242 of the connecting rod is provided with a ball-and-socket structure 2421, and the end of the outward-opening pull cable 3 is connected to the ball head structure 30, which is assembled inside the ball-and-socket structure 2421. When the connecting rod 24 rotates in the open position direction, the ball-and-socket structure 2421 of the lower pivot arm 242 drives the ball head structure 30 to move. When the displacement generated by the ball head exceeds the door lock opening stroke, the door opens.

[0072] like Figures 7 to 11 As shown, a slider 26 is provided on the back of the handle base 22, and the slider body 262 can move up and down along the groove 223 of the handle base 22. When the handle is in the single-piece state, the slider spring 261 is pressed by the base stop 222.

[0073] When the outer handle is installed from the outside of the vehicle to the inside, the slider fixing rib 263 has a guide bevel 264. At this time, the edge of the door sheet metal 11 pushes the slider 26 upward to move it. When the fixing rib 263 passes the edge of the door sheet metal 11, the slider spring 261 is squeezed by the base stop 222, pushing the slider 26 downward to move it. This causes the fixing rib 263 to be constrained by the edge of the door sheet metal 11 and cannot come out of the vehicle.

[0074] In some embodiments, the back of the handle base 22 is further provided with a first mounting hole 225 and a second mounting hole 226. The first mounting hole 225 is fixedly connected to the door sheet metal 1 by bolts, and the second mounting hole 226 is fixedly connected to the door sheet metal 1 by bolts.

[0075] When the handle is used normally or flipped upward by force F, the slider 26 forms a three-point stable fixing structure with the first mounting hole 225 and the second mounting hole 226, which improves the stability and rigidity of the fit with the sheet metal.

[0076] like Figure 12 As shown, the outward-opening pull cable 3 between the outer handle and the door lock body is divided into two parts: a first pull cable 31 pre-connected to the outer handle assembly 2, and a second pull cable 32 pre-connected to the lock body 4. A connector 5 is provided between the first pull cable 31 and the second pull cable 32, thereby improving the ease of cable assembly when the outer handle assembly is installed from the exterior sheet metal to the interior sheet metal.

[0077] Assembly Step 1: The lock body 4 is pre-fixed to the door sheet metal assembly, and the second pull cable 32 and connector 5 are in a free state.

[0078] Assembly Step 2: The outer handle assembly 2, along with the first pull cable 31, is assembled from the opening on the outside of the door sheet metal 1 into the inside of the sheet metal. After the outer handle assembly 2 is fixed to the door sheet metal 1, the second end of the first pull cable 31 is in a free state.

[0079] Assembly Step 3: Assemble the second end of the first pull wire 31 and the second end of the second pull wire 32 through the connector 5, and fix them to the door sheet metal reinforcement with clips.

[0080] This embodiment of the semi-concealed handle assembly features a reversing mechanism that redirects the upward rotation of the outer handle to a linear motion of the door lock's outward-opening cable. This allows for more flexible arrangement and selection of the relative positions of the door lock and the outer handle. Furthermore, the base in this embodiment features a stable connection structure to ensure a stable fixation between the handle and the door panel under normal or strong force.
