Detailed Description

In the description of the present invention, it is to be understood that the terms "left", "right", "upper", "lower", "front", "rear", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

The contents of the present invention are further described in detail below with reference to the specific embodiments, and fig. 1 and fig. 2 respectively show the explosion schematic diagram and the three-dimensional assembly schematic diagram of the remote control key for a vehicle according to the present invention, it can be known that the explosion schematic diagram mainly comprises an upper housing 1, a circuit board 2, a button battery 3, a lower housing 4, a door locking and pressing button 5, a door unlocking and pressing button 6, a trunk opening and closing and pressing button 7, and a flexible sealing member 8. Wherein, the upper shell 1 and the lower shell 4 are injection-molded parts and are mutually buckled to form a mounting cavity 9. The flexible sealing element 8 is horizontally arranged in the installation cavity 9 and is clamped between the upper shell 1 and the lower shell 4 so as to divide the installation cavity 9 into an upper non-sealing installation subchamber 91 and a lower full-sealing installation subchamber 92. The circuit board 2 is built in the lower totally enclosed mounting subchamber 92. The vehicle door locking pressing induction button 5, the vehicle door unlocking pressing induction button 6 and the trunk opening and closing pressing induction button 7 are uniformly arranged right above the circuit board 2 and penetrate through the flexible sealing piece 8 until extending into the upper non-sealing installation sub-cavity 91. The button cell 3 is electrically connected to the circuit board 2 and is also embedded in the lower totally enclosed installation sub-chamber 92. Corresponding to the door locking and pressing button 5, the door unlocking and pressing button 6, and the trunk opening and closing and pressing button 7, the upper case 1 is provided with a door locking and pressing area, a door unlocking and pressing area, and a trunk opening and closing and pressing area (as shown in fig. 3-9). Therefore, on one hand, the influence of the invasion of external conductive liquid on the normal use of the button cell 3 can be effectively prevented, the occurrence of the short circuit phenomenon of the cell is avoided, and the use safety of the automobile remote control key is further ensured; on the other hand, the phenomenon that the circuit board 2 is corroded by conductive liquid can be avoided, and the control performance of the circuit board 2 is ensured to have good stability and reliability.

As a further optimization of the above-described automotive fob structure, a bead 81 may also be provided around the periphery of its flexible seal 8. When the automobile remote control key is completely assembled, the pressing edge 81 is pressed between the upper case 1 and the lower case 4 (as shown in fig. 2, 3, 4, and 7). In this way, the edge pressing 81 is subjected to self-adaptive deformation under the action of pressure, so that on one hand, the position of the flexible sealing element 8 is reliably fixed, and the phenomenon of slipping caused by vibration excitation in the subsequent use process is prevented; on the other hand, the buckling gap between the upper shell 1 and the lower shell 4 is completely plugged, and conductive liquid is prevented from invading into the lower full-sealing installation sub-cavity 92 better.

Furthermore, a circuit board receiving recess 82 may be formed in the sealing member 8 for receiving the circuit board 2 (as shown in fig. 2, 3, 4, and 8). Through adopting above-mentioned technical scheme to set up to can avoid circuit board 2 to take place the position drunkenness phenomenon under putting totally enclosed installation branch chamber 92 effectively, ensure follow-up accuracy of pressing and controlling.

As is known, the silica gel material has good elastic modulus, good fatigue resistance and low purchase cost. In view of this, the above-mentioned flexible seal 8 is preferably a silicone seal.

The following problems exist in the actual operation of the automobile remote control key: in rainy days, when the automobile remote control key is completely covered by a water film, an electromagnetic wave shielding layer is formed under the action of static charges, and the emission of wireless signals is influenced. In view of this, a vacuum deposited metal film (not shown) may be attached to both the upper case 1 and the lower case 4. The existence of the vacuum evaporation metal film can effectively avoid the formation of electromagnetic wave shielding layers on the peripheries of the upper shell 1 and the lower shell 4, and ensure the reliability and sensitivity of wireless control of the automobile.

Of course, as another modified design of the above technical solution, a hydrophobic film (not shown in the figure) may be attached to both the upper casing 1 and the lower casing 4 to prevent moisture aggregation, thereby avoiding the formation of a large-area continuous water film.

In order to display the product information, a brand Logo 10 needs to be added to the lower case 4. In the prior art, the lower shell 4 is in a lower curved cambered surface shape as a whole, so that the brand Logo 10 attached to the lower shell is easily worn and scratched by foreign objects, and the information of the product is blurred, so that the overall appearance of the automobile remote control key is influenced. In view of this, as a modified design of the technical solution, the side wall of the lower housing 4 may be recessed inward to form a Logo receiving groove 41 for receiving the brand Logo 10 (as shown in fig. 2, 3, 4, and 9).

In view of securing the fixing reliability of the brand Logo 10 and reducing the molding cost as much as possible, the brand Logo 10 is preferably fixed in the Logo accommodating groove 41 by ultrasonic welding.

Finally, it should be noted that, the automobile remote control key is additionally provided with the left counterweight block 11 and the right counterweight block 12, so as to increase the overall weight of the automobile remote control key, and further ensure that a user has a good hand-held feeling. The left counterweight block 11 and the right counterweight block 12 are symmetrically distributed along the left-right direction, and are both embedded and fixed in the upper non-sealing installation sub-cavity 91 (as shown in fig. 1-4).

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
