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 in describing the present invention and simplifying the description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.
The following describes the present invention in further detail with reference to specific embodiments, and fig. 1 and fig. 2 respectively show an explosion diagram and a three-dimensional assembly diagram of the automobile remote control key according to the present invention, and it can be understood that the automobile remote control key mainly comprises a circuit board 1, an upper case 2, a button battery 3, a lower case 4, a door locking and pressing sensing button 5, a door unlocking and pressing sensing button 6, a trunk opening and closing and pressing sensing button 7, and an auxiliary top plate 9. Wherein the upper case 2 and the lower case 4 are fastened to each other to form a mounting cavity 8. The circuit board 1, the button cell 3, the door locking and pressing induction button 5, the door unlocking and pressing induction button 6 and the trunk opening and closing and pressing induction button 7 are all arranged in the installation cavity 8. The button cell 3 and the circuit board 1 are fixed and electrically connected. 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 between the upper shell 2 and the circuit board 1. The upper case 2 is provided with a door lock pressing area 21 corresponding to the door lock pressing button 5, a door unlock pressing area 22 corresponding to the door unlock pressing button 6, and a trunk open/close pressing area 23 corresponding to the trunk open/close pressing button 7, respectively. The auxiliary ceiling plate 9 is built in and fixed in the mounting cavity 8, and is fixed by the lower case 4. A battery limit sink groove 91 and a control module limit sink groove 92 extend downwards from the upper plane of the auxiliary top supporting plate 9, so as to be respectively used for placing the button battery 3 and the control module of the circuit board 1 (as shown in fig. 3-8). Therefore, the relative fixing positions of the button cell 3 and the circuit board 1 are effectively kept unchanged in the installation inner cavity 8 all the time, the phenomenon that the wiring terminal of the button cell 3 is pulled off from the circuit board 1 due to the action of exciting force or external impact force in the specific using process is avoided, and the reliability and the stability of electric conduction are ensured.
As a further refinement of the structure of the automobile remote control key, the button battery 3 and the control module of the circuit board 1 are preferably inserted into the battery limit sunken groove 91 and the control module limit sunken groove 92 in a transition fit manner. Therefore, on one hand, the maximum relative displacement between the button cell 3 and the control module of the circuit board 1 can be effectively controlled by reasonably controlling the insertion gap; on the other hand, the difficulty of inserting and assembling the control modules of the button cell 3 and the circuit board 1 is reduced, and the assembling efficiency is improved.
It is known that various designs can be used to achieve the fixing of the auxiliary ceiling plate 9 in the mounting cavity 8. However, an embodiment with simple design, easy component formation and efficient assembly is proposed herein, which is as follows: the auxiliary ceiling plate 9 is in a flat state and fixed to the lower case 4 by its periphery (as shown in fig. 1 to 4).
In the assembling process of the automobile remote control key, the upper shell 2, the circuit board 1, the button cell 3, the door locking pressing induction button 5, the door unlocking pressing induction button 6 and the trunk opening and closing pressing induction button 7 are assembled into an upper assembly body, the lower shell 4 and the auxiliary top supporting plate 9 are assembled into a lower assembly body, and then the upper assembly body is directly buckled and covered on the lower assembly body, so that better operation feasibility is required. It should be noted that, when the final capping operation is performed, the alignment precision of the button cell 3 with respect to the cell limit sinking groove 91 and the alignment precision of the control module of the circuit board 1 with respect to the control module limit sinking groove 92 need to be strictly controlled, so as to avoid the occurrence of the phenomenon that the button cell 3 and the control module of the circuit board 1 are damaged by the pressing force.
Furthermore, as a further optimization of the structure of the automobile remote control key, four mounting posts 93 may also extend upwards from the auxiliary top supporting plate 9 to support and fix the circuit board 1. When the circuit board 1 is put in place with respect to the mounting posts 93, it is fastened by means of screwing or soldering (as shown in fig. 1-4, 8), and the implementation process is quick and fast. In addition, enough accommodating space is reserved for installing the button cell 3, and the light and thin design of the automobile remote control key is well paved.
In order to ensure the alignment accuracy of the auxiliary top board 9 with respect to the lower housing 4 and further ensure the alignment accuracy with the button cell 3 and the control module of the circuit board 1 in the subsequent assembly process, a plurality of limiting notches 94 may be uniformly distributed around the peripheral edge of the auxiliary top board 9, and correspondingly, a plurality of limiting protrusions 41 (shown in fig. 1-4 and 6) adapted to the limiting notches 94 extend inward from the inner side wall of the lower housing 4.
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 water-repellent film (not shown) may be attached to both the upper case 2 and the lower case 4. The existence of the hydrophobic film can effectively prevent the moisture aggregation phenomenon, so that an electromagnetic wave shielding layer influencing the emission of wireless signals cannot be generated, and the reliability and the sensitivity of the wireless control of the automobile are further ensured.
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 42 for receiving the brand Logo 10 (as shown in fig. 1 to 4 and 7).
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 42 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 mounting cavity 8 (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.
