DETAILED DESCRIPTION

[0032] It should be noted that the following detailed descriptions are exemplary and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0033] Example 1

[0034] In a typical embodiment of the present invention, Figure 1-Figure 5 As shown, a hidden door handle is provided, including an upper door bowl 1, a door handle 2 and a lower door bowl 3, wherein the upper door bowl 1 and the lower door bowl 3 are symmetrically arranged about the door handle 2; the inner sides of the upper door bowl 1 and the lower door bowl 3 are connected to the handle base through a telescopic structure, and the telescopic structure drives the upper door bowl 1 and the lower door bowl 3 away from or close to the handle base, and the telescopic structure includes a first telescopic structure and a second telescopic structure, wherein the first telescopic structure adopts a motor drive structure, and the second telescopic structure adopts a spring press rebound structure.

[0035] In this embodiment, the first telescopic structure includes a motor 11, a motor connecting rod 13, a stretching rod 15 and a fixed shaft 14 connected in sequence; one end of the motor connecting rod 13 is fixedly connected to the motor output shaft 12, the other end of the motor connecting rod 13 is hinged to one end of the stretching rod 15, the other end of the stretching rod 15 is fixedly connected to the fixed shaft 14, and the fixed shaft 14 is rotatably mounted on the inner side of the door bowl. Furthermore, the motor connecting rod 13 and the stretching rod 15 are arranged at an obtuse angle, and the motor connecting rod 13 is vertically fixedly connected to the motor output shaft 12. The working principle of the first telescopic structure is that the motor output shaft 12 of the motor 11 rotates, thereby driving the motor connecting rod 13 to rotate around the axis of the motor output shaft at a certain angle, and the rotation process of the motor connecting rod 13 pulls the stretching rod 15, and the stretching rod 15 is connected to the door bowl through the fixed shaft 14 to move.

[0036] Since the first telescopic structure needs to be powered on to be realized, and considering that in extreme cases, the circuit may fail and the car door cannot be opened, a second telescopic structure is provided, wherein the second telescopic structure includes a pressing rod 8, a sleeve 7, a rotating tooth 6, a rotating base 18 and a spring base 5; the pressing rod 8 and the rotating tooth 6 extend into the sleeve 7, the rotating tooth 6 abuts against the rotating base 18, the rotating base 18 is located in the spring base 5, and a spring 17 is connected between the rotating base 18 and the spring base 5.

[0037] Furthermore, one end of the pressing rod 8 is fixedly connected to the inner side surface of the door bowl, the other end of the pressing rod 8 is provided with a second saw tooth 801, and a plurality of protrusions 703 are provided on the side wall surface of the pressing rod 8, one end of the protrusion 703 is the same shape as the second saw tooth 801, and the other end is arc-shaped, and the position of the protrusion 703 corresponds to the position of the second saw tooth.

[0038] Furthermore, a slide groove 702 is provided on the wall surface of the sleeve 7, a first serration 701 is provided on the end surface of the sleeve 7, and the sleeve 7 is fixed to the vehicle door body through a fixing plate 19; a rack 601 is provided on the rotating tooth 6, and the rack 601 and the protrusion 703 on the pressing rod 8 fit in the slide groove 702 of the sleeve 7, therefore, the number of racks 601, protrusions 703 and slide grooves 702 are the same.

[0039] Furthermore, the spring base 5 is fixed on the handle base 4 .

[0040] The working principle of the second telescopic structure is as follows: in the initial state, under the elastic force of the spring 17, the rack 601 and the protrusion 703 fit together in the slide groove 702 through the inclined surface, and the arc end of the protrusion 703 is close to the end of the slide groove 702. When the door bowl is pressed for the first time, the pressing rod 8 moves to the right. Since the protrusion 703 and the rack 601 are matched with an inclined surface, when the pressing rod 8 pushes the rotating tooth 6 out of the sleeve 7, the rotating tooth 6 rotates and compresses the spring through the rotating base 18. The inclined surface on the rack 601 fits with the inclined surface of the second serration 801 at the end of the sleeve 7. At this time, the door bowl can be maintained in a certain position; when the door bowl is pressed for the second time, the serrations between the two protrusions 703 push the end of the rack 601 in the sleeve 7, thereby causing the rotating tooth 6 to rotate again, so that the end of the rack 601 contacts the inclined surface 704 and enters the slide groove 702 again. Under the elastic force of the spring 17, the door bowl is reset. The working principle of the second telescopic structure is similar to the pressing and rebounding principle of a ballpoint pen. Of course, those skilled in the art can also select other pressing and rebounding structures according to needs.

[0041] In this embodiment, a limiting track 16 is provided on the door wall, and the upper end surface of the upper door bowl 1 and the lower end surface of the lower door bowl 3 are installed on the limiting track 16. The upper door bowl 1 and the lower door bowl 3 are limited by the limiting track 16 to ensure the accuracy of the movement process of the upper door bowl 1 and the lower door bowl 3.

[0042] Specifically, an inner opening pressure hand 9 and an inner pressure spring plate 10 are provided on the inner side surface of the door handle 2, and the vehicle door is opened by pressing the inner opening pressure hand 9 and the inner pressure spring plate 10. The structure here adopts the existing structure and will not be repeated here.

[0043] The usage process of the hidden door handle provided in this embodiment is as follows:

[0044] When the vehicle is unlocked, the motor 11 receives a working signal, drives the motor output shaft 12 to pull the stretching rod 15 through the motor connecting rod 13 to drive the fixed shaft 14 to move inward, and at the same time drives the upper door bowl 1 and the lower door bowl 3 to move inward together, forming a door bowl effect, so that the door handle 2 remains in the same position, and there is space for the hand to reach into all four doors of the vehicle. After the hand is reached in, the inner opening pressure hand 9 is pressed to drive the inner pressure spring plate 10 to achieve the purpose of unlocking the vehicle door.

[0045] When the vehicle is driving, the motor 11 receives a signal to resume working, drives the motor output shaft 12 to push the stretching rod 15 through the motor connecting rod 13 to drive the fixed shaft 14 to move outward, and at the same time drives the upper door bowl 1 and the lower door bowl 3 to move outward together, forming a state of restoring the door handle 2 to the same position height, keeping the overall plane of the vehicle body flat and without bumps.

[0046] In extreme cases, when the door needs to be unlocked manually, an outsider presses the surface of the upper door bowl 1 and the lower door bowl 3. Under the action of the limit track 16, the pressure is transmitted to the spring 17 through the pressing rod 8, the rotating gear 6, and the rotating base 18, and the spring 17 is kept in a compressed state through the sleeve 7, so that the upper door bowl 1 and the lower door bowl 3 sink synchronously to form a door bowl effect. There is space for the hand to reach into all four doors of the vehicle. After the hand reaches in, the inner opening pressure hand 9 is pressed to drive the inner pressure spring plate 10 to achieve the purpose of unlocking the vehicle door. It is convenient for outsiders to quickly open the door for rescue and other operations.

[0047] In extreme cases, when it is necessary to manually restore the upper door bowl 1 and the lower door bowl 3 to a position parallel to the vehicle body, an outsider can put his hand into the door bowl, and press the surface of the upper door bowl 1 and the lower door bowl 3 under the action of the limit track 16, and the spring 17 will reset, so that the upper door bowl 1 and the lower door bowl 3 will be synchronously ejected outwards to form a parallel position with the vehicle body. This will not affect the integrity of the vehicle appearance and prevent dust and rain from entering.
