The photoelectric plate through hole is provided between the light emitting end and the light receiving end and is provided in conjunction with the slider light shielding plate, and a light-transmitting hole that cooperates with the light emitting end and the light receiving end is provided on the slider light shielding plate; the weak spring is provided between the button and the slider The strong spring is arranged between the button and the button back shell, the weak spring force is less than the elastic force of the handle elastic reset device, and the strong spring force is greater than the elastic force of the handle elastic reset device; the interface plate, the reduction motor, and the driving push rod are respectively connected to the handle mounting plate, the interface plate and the reduction motor are connected to the car controller, the interface plate is also connected to the photoelectric board, the reduction motor output shaft is connected to the driving push rod, the driving push rod is rotatably connected to the handle mounting plate, and the driving push rod is arranged corresponding to the inner side of the handle head end; the bottom of the groove on the handle mounting plate is provided with bottom through holes corresponding to the light guide column and the driving push rod respectively.

[0007] This solution adopts a new type of bidirectional trigger photoelectric switch designed independently, combined with the inherent structure of the car's invisible door handle, which can not only detect the state of the door handle's tail end being pressed, but also the state of the door handle's head end being pressed and the tail end being tilted, that is, the user can trigger the bidirectional trigger photoelectric switch by pressing the head end or the tail end of the door handle. The reduction motor and the drive push rod of the electric lifting device of this solution are linked to automatically push out the head end of the door handle for the user to open the car door; in the specific use process, the user presses the head end or the tail end of the door handle, and the sinking or tilting action of the door handle's tail end causes the light guide column, button and slider in the bidirectional trigger photoelectric switch to produce displacement in two directions, and the movement of the slider causes the light shielding plate on the slider to produce a blocking or opening effect between the light emitting end and the light receiving end of the photoelectric panel, thereby making the light The receiving end cannot receive or receives a signal (generally an infrared signal).

The car controller then drives the reduction motor to work and drives the driving push rod to work, thereby automatically pushing out the front end of the door handle; the door handle itself has a rebound force. In this solution, this rebound force is greater than the weak spring force and less than the strong spring force. When the door handle is not touched, the door handle rebound force compresses the weak spring and extends the strong spring. At this time, the slider light shield is also in the middle position between the infrared emission and reception of the photoelectric panel. The infrared receiver cannot receive any signal, and there is no trigger signal at this time; the bottom of the groove on the handle mounting plate is provided with bottom through-holes corresponding to the light guide column and the driving push rod, respectively, which can allow the light guide column and the driving push rod to pass through the bottom through-holes and contact the handle.

[0008] As a preferred embodiment of the present invention, the button is provided with a sliding groove on its outer side, and a sliding bar is provided within the button housing, wherein the sliding groove and the sliding bar cooperate with each other. The button of this embodiment utilizes the cooperation of the sliding groove and the sliding bar within the button housing to restrict the button's rotation, thereby preventing the light shielding plate on the slider from rotating due to button rotation and thus losing its shielding function between the light emitting end and the light receiving end. Simultaneously, the light shielding plate on the slider passes through the light shielding plate through-hole on the button, thereby also providing a positioning restriction for the slider.

[0009] As a preferred embodiment of the present invention, the photoelectric panel is provided with a lighting lamp, the light guide column has a light guide hole in the middle, and the light guide hole is arranged corresponding to the lighting lamp. The end of the light guide column that is in close contact with the end of the handle is provided with a silicone sleeve. This embodiment can be equipped with a lighting lamp to indicate the location of the door handle in dark environments.

[0010] As a preferred embodiment of the present invention, the slider's dome-shaped body has a weak spring retaining groove on the side closest to the button, and the button has a strong spring retaining groove on the side closest to the button's rear housing. This arrangement allows for end positioning and limiting of both the weak and strong springs; the button's rear housing can also be equipped with a strong spring retaining groove identical to that on the button.

[0011] As a preferred solution of the present invention, a positioning boss is provided on the inner side of the button rear shell. The shape of the positioning boss matches the through hole of the photoelectric panel. A light-transmitting groove is provided in the middle of the positioning boss, and the photoelectric panel passes through the positioning boss and is connected to the button rear shell. The light-emitting end and the light-receiving end on the photoelectric panel are located on both sides of the light-transmitting groove. The top of the positioning boss is provided with an inwardly recessed light-shielding plate slot. The light-shielding plate and the light-shielding plate slot are pluggable. Because the slider will produce linear displacement in two directions starting from the initial position, sufficient space needs to be reserved at the bottom end of the slider light-shielding plate. This solution adopts a hollow positioning boss for the slider light-shielding plate to be inserted, and the photoelectric panel is inserted on the outside of the positioning boss, so that the relative positions of the slider light-shielding plate and the photoelectric panel can be positioned.

[0012] As a preferred solution of the present invention, the electric lifting device includes a mounting bracket and a motor cover. The mounting bracket and the motor cover are connected to form an equipment compartment. The mounting bracket is connected to the handle mounting plate. The interface board, reduction motor, and drive push rod are arranged in the equipment compartment. The button housing is connected to the mounting bracket. The equipment compartment is located outside the handle mounting plate. The drive push rod is rotatably connected to the mounting bracket, and the drive push rod is partially exposed outside the equipment compartment. This solution adopts the method of adding an electric lifting device and a two-way trigger photoelectric switch to the original handle mounting plate installed by the factory, rather than using an alternative integrated product. This is because the replacement handle mounting plate is not an original product and its quality cannot be guaranteed. In addition, installing this product on the original handle mounting plate is suitable for vehicle modification requirements.

[0013] As a preferred solution of the present invention, the output shaft of the reduction motor is connected to the driving gear, and the driving mandrel is provided with a passive gear or a plurality of passive teeth. In this solution, the reduction motor and the driving mandrel are connected by a gear meshing transmission. The driving mandrel can be provided with a passive gear, or only with a partial toothed belt and toothed ring. Because the driving mandrel has a limited rotation angle and needs to rotate back after rotation, the reduction motor also needs to be able to rotate forward and reverse.

[0014] As a preferred embodiment of the present invention, the driving push rod includes a semicircular push rod and a rotating shaft perpendicularly passing through the center of the semicircular push rod. The rotating shaft is connected to the semicircular push rod, and both ends of the rotating shaft are rotatably connected to the mounting bracket. The head of the semicircular push rod is exposed outside the equipment compartment, and the head of the semicircular push rod is arranged to cooperate with the inner side of the handle head end. The outer surface of the semicircular push rod is provided with a plurality of passive teeth that cooperate with the active gear. The semicircular push rod of the driving push rod of this embodiment is exposed, which facilitates its rotation and ejection of the door handle head end. After ejection, it rotates back after a delay, and the door handle can return to its original position through an elastic reset device.

[0015] As a preferred solution of the present invention, a thickness-adjustable fixing cover is provided at the connection between the mounting bracket and the handle mounting plate. During installation, fixing covers of varying thicknesses are added at the connection between the mounting bracket and the handle mounting plate to adjust the distance between the mounting bracket and the handle mounting plate to suit the actual installation environment.

[0016] Compared with the prior art, the beneficial effects of the present invention are: it adopts a new type of bidirectional trigger photoelectric switch with long service life and low failure rate; it is convenient for users to use, that is, pressing the front end or the rear end of the door handle can push out the front end of the door handle through the electric drive system.

[0053] A thickness adjustment fixing cover 81 is provided at the connection between the mounting bracket 8 and the handle mounting plate 2 .

[0054] The specific working process is: in the initial state, the handle 1 of the car's invisible door handle has a rebound force under the action of the elastic reset device. This rebound force is greater than the elastic force of the weak spring 46 and less than the elastic force of the strong spring 44. When the user does not touch the handle 1, the rebound force of the handle 1 compresses the weak spring 46, and the strong spring 44 is in an extended state. At this time, the shading plate 472 of the slider 47 is in the shading plate slot 423 of the positioning boss 421 on the button rear shell 42, and blocks the infrared light between the light emitting end 431 and the light receiving end 432 of the photoelectric panel 43, that is, the shading plate 472 is located in the middle position between the infrared emission and reception, and the infrared receiver cannot receive any signal, and there is no trigger signal at this time.

[0055] When the user presses the tail end of the handle 1 of the car's invisible door handle, the handle 1 transmits pressure to the silicone sleeve 49, the light guide column 48, the slider 47, the button 45, and the strong spring 44 in sequence. The strong spring 44 contracts under the force, and the slider 47 moves downward toward the button rear shell 42. The light-transmitting hole 474 on the light-shielding plate 472 of the slider 47 is located between the light-emitting end 431 and the light-receiving end 432 of the photoelectric panel 43 after the slider 47 moves downward. The infrared light between the light-emitting end 431 and the light-receiving end 432 can pass through the light-transmitting hole 474 and the light-transmitting groove 422 on the positioning boss 421. When the infrared receiver receives the signal, it is amplified and processed by the subsequent signal and then connected to the car controller through the interface board 5. The controller controls the reduction motor 6 to rotate and the lighting lamp lights up. The reduction motor 6 drives the driving push rod 7 to rotate and pushes the head end of the handle 1 out.

[0056] When the user presses the front end of the handle 1 of the car's invisible door handle, the rear end of the handle 1 rises, and the weak spring 46 that was compressed in the original state extends. The weak spring 46 drives the slider 47 to move up in the direction away from the button rear shell 42. The bottom of the light shielding plate 472 of the slider 47 moves up and leaves the space between the light emitting end 431 and the light receiving end 432 of the photoelectric panel 43. At this time, the space between the light emitting end 431 and the light receiving end 432 of the photoelectric panel 43 is no longer blocked by the light shielding plate 472. The infrared light between the light emitting end 431 and the light receiving end 432 can pass through the light-transmitting groove 422 on the positioning boss 421. When the infrared receiver receives the signal, it is amplified and processed by the subsequent signal and then connected to the car controller through the interface board 5. The controller controls the reduction motor 6 to rotate and the lighting lamp lights up. The reduction motor 6 drives the driving push rod 7 to rotate and pushes the front end of the handle 1 out.

[0057] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
