[0035] For example, see Figures 1 to 6 As shown: a keyless entry and starting system for a vehicle includes an upper cover 10 and a lower cover 20.

[0036] Specifically:

[0037] The upper cover 10 is made of a light-conducting material. A touch area 111 is printed on the upper surface of the upper cover 10, and a physical button 112 is provided in the middle of the upper cover 10. Obviously, the touch area 111 can be multiple and arranged around the physical button 112, for realizing various control functions such as locking and unlocking. A sealing boss 121 extending downward is provided on the edge of the lower surface of the upper cover 10, and at least two positioning bumps 122 are provided on the inner side wall of the sealing convex strip 121. The positioning bump 122 can be in the shape of a "7".

[0038] The upper surface of the lower cover 20 is provided with four assembly bosses 211 distributed in a square shape. That is, the connecting line of the assembly bosses 211 is a square or a rectangle. The edge of the lower cover 20 is provided with two upwardly extending closed rings 212, and a sealing groove 213 is formed between the two closed rings 212. That is, the sealing groove 213 is in a ring shape surrounding the edge of the lower cover 20 and the opening is facing upward. Usually, a sealing ring 214 is clamped at the bottom of the sealing groove 213.

[0039] When the upper cover 10 and the lower cover 20 are put together, a receiving space 30 is formed inside the two. At this time, the sealing boss 121 is stuck in the sealing groove 213, and the sealing ring 214 further enhances the sealing performance of the receiving space 30.

[0040] Further:

[0041] The accommodation space 30 is provided with a light guide plate 40 , a PCBI 50 , a PCB II 60 , a battery 70 , a coil 80 , and a magnetic isolation plate 90 from top to bottom.

[0042] The light guide plate 40 is provided with side through holes 41 corresponding to the touch areas 111 in pairs. That is, the positions of the touch areas 111 and the side through holes 41 are aligned in pairs, or in other words, the downward projection of the touch areas 111 and the downward projection of the side through holes 41 coincide. The middle part of the light guide plate 40 is provided with a middle through hole 42 corresponding to the physical button 112, and a press switch 43 matching the physical button 112 is provided in the middle through hole 42. That is, after pressing the physical button 112 downward, the physical button 112 just touches the press switch 43. The side of the light guide plate 40 is provided with light guide plate card slots 44 corresponding to the positioning protrusions 122 in pairs. That is, the positioning protrusions 122 are stuck in the corresponding light guide plate card slots 44, forming a better positioning. When the positioning protrusion 122 is in a “7” shape, the upper surface of the light guide plate 40 will be supported by the protruding step in the middle of the positioning protrusion 122 , so that there is a suitable gap between the light guide plate 40 and the upper cover 10 .

[0043] The upper surface of the PCBI50 is provided with sensing areas 51 corresponding to the side through holes 41 in pairs and matching the touch areas 111 in pairs. That is, after the user touches a certain touch area 111, it can be sensed by the sensing area 51. The sensing area 51 can be a variety of common forms such as an infrared sensor set there. The side of the PCBI50 is provided with PCBI card slots 52 corresponding to the positioning protrusions 122 in pairs. That is, the positioning protrusions 122 are correspondingly stuck in the corresponding PCBI card slots 52 in pairs, thereby realizing the positioning of the PCBI50. At this time, the lower part of the push switch 43 is supported on the middle part of the upper surface of the PCBI50. That is, the middle part of the PCBI50 is solid.

[0044] A rectangular through hole 61 is provided in the middle of the PCBⅡ60, and a semicircular groove 611 is provided on the side of the rectangular through hole 61, which matches the assembly boss 211 in pairs. That is, the positioning bosses 211 are just correspondingly stuck in the semicircular groove 611 in pairs, so as to achieve the positioning of the PCBⅡ60. The upper part of the battery 70 is stuck in the rectangular through hole 61. A PCBⅡ card slot 62 corresponding to the positioning protrusion 122 is provided on the side of the PCBⅡ60. That is, the positioning protrusion 122 is correspondingly stuck in the PCBⅡ card slot 62 in pairs, so as to achieve the positioning of the PCBⅡ60. In this way, the positioning of the upper cover 10 and the lower cover 20 is indirectly achieved, so that the two cannot rotate relative to each other, and the components in the accommodating space 30 are more compact.

[0045] A middle through hole 81 is defined in the middle of the coil 80 , and the lower portion of the battery 70 is locked in the middle through hole 81 .

[0046] The magnetic isolation plate 90 is in the shape of a square plate and is clamped between four assembly bosses 211 .

[0047] Thus, in specific operation, the light guide plate 40 receives light transmission, and PCBI50, PCBⅡ60, battery 70, magnetic isolation plate 90, coil 80, push switch 43, etc. realize touch and signal transmission between PEPS and the car receiving system. Since the various components of the keyless entry and start system for the car are directly and indirectly positioned and connected, the structure is extremely compact. At the same time, the structure combining touch and physical buttons is adopted, which is more convenient to use.

[0048] It should be noted that:

[0049] The side of the lower box 20 is located on a closed circle 212 on the inner side and can also be provided with positioning notches 2121 that match the positioning protrusions 122 in pairs. That is, the positioning protrusions 122 are correspondingly clamped in the positioning notches 2121 in pairs, so that the positioning of the upper box 10 and the lower box 20 is achieved.

[0050] It should be noted that the embodiments of the present invention are mainly to illustrate the connection between components, while the circuit connection and control principle belong to the prior art and will not be described in detail. The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
