Detailed Description

Various embodiments of the present invention will be described with reference to the accompanying drawings. In the drawings in the specification, elements having similar structures or functions will be denoted by the same reference numerals. It is to be understood that the drawings are for purposes of illustrating various embodiments of the invention and are not intended as an exhaustive description of the invention or as a limitation on the scope of the invention.

FIG. 1 illustrates an automobile 10 in accordance with an embodiment of the present invention. The automobile 10 is provided with a door, which the passenger can open by pulling a handle portion 21 of the door. The vehicle 10 employs a door handle assembly 20, described below, so that the doors do not open on their own in the event of a severe side impact.

Although only one common vehicle model is illustrated in fig. 1, it will be understood by those skilled in the art that the door handle assembly 20 of the present invention may be applied to various vehicle models not illustrated, such as sports cars, vans, off-road vehicles, and the like.

As shown in fig. 2, the door handle assembly 20 includes a handle portion 21, a weight 22, a mounting bracket 23, and a cable 24.

Both the handle portion 21 and the weight 22 are rotatably mounted to the mounting bracket 23. Specifically, the right end 218 of the handle portion 21 is inserted into a slot of the mounting bracket 23 and rotates about a fixed axis within the slot. The distal end 219 of the handle portion 21 is hooked to the weight 22. The mounting bracket 23 is a fixed member on the vehicle door, and only a part of the mounting bracket 23 is illustrated in fig. 2.

Referring to fig. 3, the handle portion 21 includes a handle 211 and a pull rod 212, and the handle 211 is fixedly connected to the pull rod 212 and is substantially perpendicular thereto. The mounting bracket 23 is omitted from fig. 3 for clarity of illustration. The right end 214 of the handle 211 (i.e., the right end 218 of the handle portion 21) is rotatably mounted to the mounting bracket 23, the left end 215 of the handle 211 is fixedly coupled to the fixed end 216 of the pull rod 212, and the free end 217 of the pull rod 212 (i.e., the distal end 219 of the handle portion 21) is provided with the hook portion 213. The hook 213 projects from the free end 217 of the lever 212 in the direction of the counterweight 22, the hook 213 hooking the tab 221 of the counterweight 22 (see fig. 5). The handle portion 21 rotates with the right end 214 of the handle 211 as a fulcrum. When the passenger opens the door, grips the handle 211 and pulls the handle 211 outward, and the handle 211 and the pull rod 212 rotate together in a direction away from the weight 22 (clockwise direction in fig. 3). In fig. 3, the outer casing of the handle 211 is also removed for clarity of illustration.

Referring to fig. 4 and 5, the weight 22 includes a body 222 and a pull ring 221. A pull ring 221 projects from the body 222 toward the free end 217 of the pull rod 212. The tab 221 is formed in a ring shape and is hooked to the hook 213. Alternatively, the weight 22 may be provided with any other structure that can be hooked by the hook 213, for example, another hook that is engaged with the hook 213, instead of the pull ring 221. Alternatively, a hook may be provided on the counterweight 22 and a pull ring may be provided on the pull rod 212.

As shown in fig. 4, the counterweight 22 is generally fan-shaped, and the counterweight 22 is rotatably coupled to the mounting bracket 23 via a rotational axis 26 (see fig. 3).

A spring 25 (see fig. 3) is sleeved on the rotating shaft 26, the spring 25 biases the balance weight 22 to rotate the balance weight 22 in a direction away from the pull rod 212 (counterclockwise direction in fig. 3), wherein one end of the spiral line of the spring 25 is fixed to the balance weight 22, and the other end is fixed to the mounting bracket 23, forming a torsion spring 25.

When the passenger opens the door, the pull rod 212 rotates away from the weight 22 (clockwise in fig. 3), and the hook 213 of the pull rod 212 hooks the pull ring 221, thereby rotating the weight 22 toward the pull rod 212 (clockwise in fig. 3) against the elastic force of the torsion spring 25. When the door is opened, the handle portion 21 rotates in the same direction as the weight 22.

A cable 24 is connected to one side of the counterweight 22, and when the cable 24 is pulled, the lock of the door is unlocked. When the passenger opens the door, the counterweight 22 rotates in a direction approaching the pull rod 212, and when the counterweight 22 rotates by a predetermined angle, the counterweight 22 pulls the pull cable 24, and the door lock is unlocked. If the weight 22 is rotated by an angle less than a predetermined angle, the cable 24 cannot be pulled and the door lock cannot be opened. The connection structure of the cable 24 and the lock of the vehicle door may adopt a common connection structure in the art, and will not be described in detail.

Referring to fig. 4 and 5, the weight 22 is provided with a stopper 27. The stopper 27 is provided on the body 222 and protrudes from the body 222 toward the free end 217 of the pull rod 212. The stopper portion 27 is configured to: when the handle portion 21 is not rotated and the weight 22 is rotated in a direction approaching the pull rod 212, the hook portion 213 is abutted so that the rotation angle of the weight 22 is smaller than a predetermined angle; and is displaced from the hook portion 213 when the handle portion 21 is rotated to rotate the weight 22 so that the rotation angle of the weight 22 is greater than or equal to a predetermined angle. Thus, in an unexpected situation such as a severe side collision of the vehicle, the lock of the door is not opened by itself as long as the handle portion 21 is not pulled, but is normally opened when the door is normally opened and the handle portion 21 is pulled.

In the present embodiment, the stopper portion 27 has a flat structure so as to be offset from the hook portion 213 when the door is normally opened. Alternatively, the stopper portion 27 may be formed in other shapes.

The stopper portion 27 is provided at the center of the body 222 in the direction of the rotation shaft 26, so that a torque in the direction of the rotation shaft 26 is less likely to be generated in the weight 22 when the stopper portion 27 abuts against the hook portion 213.

The stopper portion 27 protrudes from the body 222 by a length shorter than that of the tab 221, so that it is not easily interfered with the hook portion 213 when the door is normally opened.

The working principle of the stopper portion 27 is explained below with reference to fig. 6 to 8.

Fig. 6 illustrates the door handle assembly 20 when the door latch is normally open. The handle 211 is pulled outward, the handle 211 and the pull rod 212 rotate together in a direction (clockwise direction in fig. 6) away from the weight 22, and the weight 22 is hooked by the pull rod 212 and also rotates in a direction (clockwise direction in fig. 6) toward the pull rod 212, and at this time, the pull rod 212 is retreated in the clockwise direction, and although the weight 22 also rotates in the clockwise direction, the stopper 27 does not abut against the hook portion 213, the weight 22 smoothly rotates through a predetermined angle, the cable 24 is pulled, and the door lock is normally opened.

Fig. 7 illustrates the door handle assembly 20 in the event of a severe side impact to the vehicle 10. When the automobile 10 is seriously crashed on the side, although the handle portion 21 is not rotated, the weight 22 is rotated in a direction (clockwise direction in fig. 7) to approach the pull rod 212 due to inertia, and when the weight 22 is rotated to an angle shown in fig. 7, the stopper portion 27 abuts against the hook portion 213, so that the weight 22 cannot be rotated any more, and the angle shown in fig. 7 is smaller than the predetermined angle, so that the cable 24 cannot be pulled, and the lock of the door cannot be opened.

Fig. 8 is a comparison view of fig. 7, which is used for explaining the operation of the stopper portion 27 and is not used for limiting the present invention. In fig. 8, only the stopper portion 27 is removed, and the other structures are the same as those of the door handle assembly 20 of fig. 7. When the vehicle 10 has a severe side impact after the stopper portion 27 is removed, although the handle portion 21 is not rotated, the weight 22 is rotated in a direction (clockwise direction in fig. 8) close to the pull rod 212 by inertia, and since there is no hindrance from the stopper portion, the weight 22 can be rotated to a maximum angle at which it can be rotated, which is larger than the above-mentioned predetermined angle, so that even if the passenger does not operate the handle portion 21, the cable 24 is pulled, and the lock of the door is automatically opened.

The door handle assembly 20 of the present invention prevents the door lock from being opened when the handle portion 21 is not rotated by the operator by providing the stopper portion 27 on the counterweight 22, thereby preventing the door lock from being accidentally opened. The vehicle employs the door handle assembly 20 to prevent accidental door latch opening during a severe side impact.

Further, as shown in fig. 9, the door handle mounting bracket 23 is provided with a recessed portion 231, the weight 22 is provided in the recessed portion 231, and the bottom surface of the recessed portion 231 is provided with two reinforcing ribs 232.

When the passenger needs to open the door, the handle 211 is pulled to rotate in a direction (clockwise direction in fig. 3) away from the counterweight 22, so as to drive the pull rod 212 to rotate in a direction (clockwise direction in fig. 3) away from the counterweight 22, at this time, the hook-shaped portion 213 of the pull rod 212 hooks the pull ring 221 of the counterweight 22, and the pull rod 212 drives the counterweight 22 to rotate in a direction (clockwise direction in fig. 3) away from the door handle mounting bracket 23. The cable 24 is connected to one side of the weight 22, and the weight 22 rotates clockwise to pull the cable 24 to the left in fig. 3, so that the vehicle lock is unlocked.

Referring to fig. 10, when the door is opened when the door is unlocked, the occupant releases the handle 211 and the counterweight 22 loses the tension of the rod 212 and thus snaps back under the action of the spring 25 to hit the bottom surface of the door handle mounting bracket 23. Since the bottom surface of the door handle mounting bracket 23 is provided with the elongated reinforcing bead 232 as shown in fig. 5. The reinforcing ribs 232 are aligned in a direction parallel to the rotational axis 26 of the weight 22 (vertical direction in fig. 9) and extend in a direction perpendicular to the rotational axis 26 (horizontal direction in fig. 9). During collision, the balance weight 22 abuts against the reinforcing rib 232 and is in contact with the reinforcing rib 232, so that the contact area is reduced, and the balance weight 22 is prevented from directly contacting with the bottom surface of the mounting bracket 23 to make loud sound.

In the present embodiment, the number of the reinforcing ribs 232 is two, thereby forming a stable support structure for the weight 22. Of course, alternatively, the number of the reinforcing ribs 232 may be set as needed.

In the present embodiment, the rib 232 has an arc-shaped structure as shown in fig. 11, and when the weight 22 is rotated, the surface of the weight 22 abuts against a point on the arc. The weight 22 is in point contact with the rib 232. Alternatively, the reinforcing rib may have a triangular structure, and the balance weight abuts against the apex of the triangular structure. Alternatively, as shown in fig. 12, the reinforcing ribs 232' may also be formed in a ramp-like structure. The counterweight 22 'abuts a point on the slope of the stiffener 232'. Alternatively, the ribs may be of rectangular configuration such that the weight is in contact with the reinforcing rib line.

In other embodiments, instead of the elongated rib, a dot-shaped protrusion or a hemispherical protrusion may be provided. Thus, when the balance weight is rotated, the generated sound is reduced because the balance weight is only contacted with the protruding point.

In other embodiments, the protrusion or bead may be a resilient member. For example, they may be made of rubber or the like and fixed to the bottom surface of the door handle mounting bracket 23. Thus, when the weight 22 is rotated, since the elastic member is collided, the collision is buffered, not only the sound generated is reduced, but also the fatigue failure of the material due to long-term impact is avoided, and the service life of the weight 22 and the door handle mounting bracket 23 is prolonged.

While specific embodiments of the invention have been described above, it will be appreciated by those skilled in the art that this is by way of example only, and that the scope of the invention is defined by the appended claims. Various changes and modifications to these embodiments may be made by those skilled in the art without departing from the spirit and scope of the invention, and these changes and modifications are within the scope of the invention.
