Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of automobile parts, and relates to an intelligent automobile door handle. BACKGROUND

[0002] Now most new energy vehicles are equipped with hidden handles, which greatly improve the appearance of the vehicle, but there are also safety hazards, and in traffic accidents, the handle cannot be pulled open, the door cannot be pulled open, and rescue is delayed. Therefore, the semi-hidden handle not only has low cost, but also does not delay rescue. The unlocking mechanism is also arranged on the semi-hidden handle, the handle is pulled on the handle body, and the thumb is pressed on the unlocking button of the handle body to pull open the door. However, the handle body is relatively thin, and the unlocking mechanism cannot be completely arranged in the handle body. For example, in the Chinese utility model patent with application No. 2021207943581, the micro-motion button is arranged on the upper lifting handle, and the micro-motion switch is arranged on the fixed handle seat. In the normal state, the micro-motion button is separated from the micro-motion switch, and when the micro-motion button is pressed, the micro-motion button presses the contact of the micro-motion switch to realize unlocking or locking of the door. Compared with the unlocking mechanism with only the micro-motion switch, the above-mentioned handle has a micro-motion button, and the micro-motion button is swingingly connected to the upper lifting handle in cooperation with the torsional spring. Once the micro-motion button is damaged or the torsional spring is disabled, unlocking cannot be realized. CONTENT OF THE UTILITY MODEL

[0003] The utility model aims at the above-mentioned problems existing in the prior art, and provides an intelligent automobile door handle, which cancels the micro-motion button and directly presses the contact of the micro-motion switch to realize unlocking or locking, thereby reducing the cost of manufacturing the micro-motion button, prolonging the service life, and being not easy to be damaged.

[0004] The utility model discloses a kind of intelligent automobile door handles, including handle seat being installed on the door panel of car, handle body, it is characterized in that, handle seat bottom has two protruding installation arms, two installation arms are connected with pivot, handle body has two protruding swing arms, pivot is rotatably connected on the swing arm front end, handle seat is fixed with micro-motion switch, handle body upper end surface is opened with the unlocking hole for the upper end of micro-motion switch to expose.

[0005] Further, the upper end surface of the micro-motion switch is flush with the upper end surface of the handle body.

[0006] Further, a reset torsional spring is sleeved on the pivot, one end of the reset torsional spring is buckled on the protruding portion of the handle seat, and the other end of the reset torsional spring is buckled on the swing arm.

[0007] Further, the micro-motion switch has a mounting ear, a bolt hole is opened on the mounting ear, and the micro-motion switch is connected to the bottom surface of the handle seat through a bolt.

[0008] Further, the end surface of the handle seat and the handle body is fixed with several rubber pads.

[0009] Further, the one mounting arm is fixed with a disc damper, the disc damper is connected with a gear, the oscillating arm corresponding to the mounting arm has an arc-shaped tooth portion, and the arc-shaped tooth portion is engaged with the gear.

[0010] Further, the unlocking hole is square, and the distance between the micro switch and the unlocking hole is 0.4-0.6 mm.

[0011] The micro switch is connected to the vehicle-mounted circuit board through a signal line, after the micro switch is pressed by a finger, the vehicle-mounted circuit board receives the instruction through the signal line and starts the door lock mechanism through a control line, and the door lock mechanism performs the action of opening or locking the door. The handle body does not need to install the micro switch, which improves the structural strength, and when pulling the handle body to open the door, the micro switch is avoided due to the setting of the unlocking hole, so as not to affect the micro switch.

[0012] Compared with the prior art, the intelligent automobile door handle has the following advantages:

[0013] 1. The micro switch is installed on the handle seat, which does not occupy the space of the handle body, and only needs to open the unlocking hole on the handle body to expose the micro switch.

[0014] 2. The micro switch is simple and quick to replace, and the micro switch can be replaced without disassembling the handle body.

[0015] 3. It has a disc damper, which avoids the reset torsion spring from quickly bouncing the handle body to the handle seat, the gear of the damper drives the oscillating arm, so that the entire handle body slowly oscillates to the original position, avoiding direct collision and damage and noise.

[0016] 4. The handle body does not need to install the micro switch, and can be designed as a solid structure to improve the strength of the handle body. BRIEF DESCRIPTION OF DRAWINGS

[0023] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0024] like Figures 1-3 As shown, this smart car door handle includes a handle base 2 and a handle body 3 mounted on the car door sheet metal 1. The bottom of the handle base 2 has two protruding mounting arms 23, and a rotating shaft 5 is connected between the two mounting arms 23. The handle body 3 has two protruding swing arms 6. The bottom of the handle base 2 has a clearance hole 21 for the swing arms 6 to pass through. The front end of the swing arm 6 is rotatably connected to the rotating shaft 5. A micro switch 7 is fixed on the handle base 2. The upper surface of the handle body 3 has an unlocking hole 31 for the upper end of the micro switch 7 to be exposed.

[0025] like Figure 4 As shown, a reset torsion spring 8 is fitted on the rotating shaft 5. One end of the reset torsion spring 8 is snapped onto the protrusion 22 of the handle seat 2, and the other end of the reset torsion spring 8 is snapped onto the swing arm 6.

[0026] like Figure 5 As shown, the upper surface of the micro switch 7 is flush with the upper surface of the handle body 3. The micro switch 7 has a mounting ear 71 with bolt holes. The micro switch 7 is connected to the bottom surface of the handle seat 2 by bolts.

[0027] Several rubber pads 9 are fixed on the end face where the handle seat 2 and the handle body 3 fit together. The rubber pads 9 play a buffering role to prevent the handle body 3 from impacting the handle seat 2 and the friction generated between the two contact surfaces when the car is moving under the force of the return spring.

[0028] A disc damper 4 is fixed to one of the mounting arms 23, and a gear 41 is connected to the disc damper 4. The swing arm 6 corresponding to the mounting arm 23 has an arc-shaped tooth 24, which meshes with the gear 41. The gear 41 of the damper drives the swing arm 6, causing the entire handle body 3 to swing slowly back to its original position, avoiding direct collision and damage or noise.

[0029] The unlocking hole 31 is square, and the distance between the micro switch 7 and the unlocking hole 31 is 0.4-0.6mm. When the handle body 3 and the handle base 2 are in contact, the upper end of the micro switch 7 passes through the unlocking hole 31. The distance is set to avoid the edge of the unlocking hole 31 from contacting or being squeezed by the micro switch 7.

[0030] The micro switch 7 is connected to the vehicle-mounted circuit board through a signal line. After the micro switch 7 is pressed by a finger, the vehicle-mounted circuit board receives the instruction through the signal line and starts the door lock mechanism through a control line. The door lock mechanism performs the action of opening or locking the door. The handle body 3 does not need to be installed with the micro switch 7, which improves the structural strength, and when the handle body 3 is pulled to open the door, the micro switch 7 is not affected because the unlocking hole 31 is arranged to avoid the contact point on the micro switch 7.

[0031] The specific embodiments described herein are merely illustrative of the spirit of the present application. Those skilled in the art of the present application can make various modifications or supplements to the described specific embodiments or replace them with similar ways, but will not deviate from the spirit of the present application or exceed the scope defined by the appended claims.
