Detailed Description

Examples, see fig. 1-6: a keyless entry and start system for a vehicle includes an upper cover 10 and a lower cover 20.

Specifically, the method comprises the following steps:

the cover 10 is made of a light-conductive material. The upper surface of the upper cover 10 is printed with a touch area 111, and the middle of the upper cover 10 is provided with a physical key 112. Obviously, the touch area 111 may be a plurality of areas arranged around the physical key 112 for implementing various control functions such as locking and unlocking. The edge of the lower surface of the upper cover 10 is provided with a sealing boss 121 extending downwards, and the inner side wall of the sealing convex strip 121 is provided with at least 2 positioning lugs 122. The positioning protrusion 122 may have a 7 shape.

The upper surface of the lower cover 20 is provided with 4 assembling convex columns 211 which are distributed in a square shape. That is, a line connecting the fitting bosses 211 has a square or rectangular shape. The edge of the lower cap 20 is provided with 2 sealing rings 212 extending upwards, and a sealing groove 213 is formed between the 2 sealing rings 212. That is, the sealing groove 213 has a ring shape surrounding the edge of the lower cap 20 and opens upward. Typically, a seal ring 214 is captured in the bottom of the seal groove 213.

The upper cap 10 and the lower cap 20 are combined together to form a receiving space 30 therein. At this time, the sealing boss 121 is caught in the sealing groove 213, and the sealing ring 214 further enhances the sealability of the receiving space 30.

Further:

the accommodating space 30 is provided with a light guide plate 40, a PCBI50, a PCB II 60, a battery 70, a coil 80 and a magnetic isolation plate 90 from top to bottom.

The light guide plate 40 is provided with side through holes 41 corresponding to the touch regions 111 in pairs. That is, the position of the touch region 111 and the position of the side through hole 41 are aligned two by two, or the downward projection of the touch region 111 and the downward projection of the side through hole 41 are overlapped. The middle of the light guide plate 40 is provided with a middle through hole 42 corresponding to the physical key 112, and the middle through hole 42 is provided with a push switch 43 matching with the physical key 112. That is, after the physical key 112 is pressed down, the physical key 112 just touches the push switch 43. The light guide plate 40 has light guide plate slots 44 on its sides corresponding to the positioning protrusions 122. That is, the positioning protrusions 122 are locked in the corresponding light guide plate locking grooves 44, resulting in better positioning. When the positioning protrusion 122 is shaped like a letter "7", the upper surface of the light guide plate 40 is supported by the protruding step at the middle of the positioning protrusion 122, so that a proper gap is formed between the light guide plate 40 and the upper cover 10.

The upper surface of the PCBI50 is provided with sensing areas 51 which correspond to the side through holes 41 in pairs and are matched with the touch areas 111 in pairs. That is, the user can be sensed by the sensing area 51 when touching any one of the touch areas 111. The sensing region 51 may be provided with an infrared sensor or the like in various conventional manners. The side of the PCBI50 is provided with PCBI slots 52 corresponding to the positioning bumps 122 in pairs. That is, every two of the positioning bumps 122 are correspondingly clamped in the corresponding PCBI clamping slots 52, so that the PCBI50 is positioned. At this time, the lower portion of the push switch 43 is supported at the middle of the upper surface of the PCBI 50. That is, the central portion of the PCBI50 is solid.

The middle part of the PCB II 60 is provided with a rectangular through hole 61, and the side edge of the rectangular through hole 61 is provided with a semicircular groove 611 matched with the assembling convex column 211 in pairs. Namely, the positioning convex columns 211 are exactly clamped in the semicircular grooves 611 in pairs, so that the positioning of the PCB II 60 is realized. The upper portion of the battery 70 is caught in the rectangular through-hole 61. The side of the PCB II 60 is provided with a PCB II slot 62 which corresponds to the positioning lug 122 in pairs. Namely, the positioning bumps 122 are correspondingly clamped in the second PCB clamping grooves 62 in pairs, so that the second PCB 60 is positioned. Thus, the positioning of the upper cover 10 and the lower cover 20 is indirectly achieved, so that the two covers cannot rotate relatively, and the components in the accommodating space 30 are compact.

The coil 80 has a central passage 81 in the middle thereof, and the lower portion of the battery 70 is caught in the central through hole 81.

The magnetic isolation plate 90 is square plate-shaped, and the magnetic isolation plate 90 is clamped between the 4 assembling convex columns 211.

In this way, during specific operation, the light guide plate 40 transmits light, and the PCBI50, the PCB ii 60, the battery 70, the magnetic isolation plate 90, the coil 80, the push switch 43 and the like realize touch and signal transmission between the PEPS and the automobile receiving system. As the parts of the keyless entry and starting system for the vehicle are directly and indirectly positioned and clamped, the structure is extremely compact. Meanwhile, a structure combining touch and entity keys is adopted, so that the use is more convenient.

It should be noted that:

a sealing ring 212 on the opposite inner side of the lower case 20 may also be provided with positioning notches 2121 matching with the positioning protrusions 122 in pairs. That is, the positioning protrusions 122 are correspondingly engaged in the positioning notches 2121 in pairs, so as to position the upper case 10 and the lower case 20.

It should be noted that the embodiments of the present invention mainly describe the manner of clamping between components, and the circuit connection and control principle belongs to the prior art, and are not described again.

The above description is only a preferred embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by using the contents of the present specification and the accompanying drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
