[0035] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. Figures 1 to 9 The described embodiments are exemplary and are intended to be used to explain the embodiments of the present invention, but should not be construed as limiting the present invention.

[0037] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0038] In the embodiments of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0039] In one embodiment of the present invention, Figures 1 to 9 As shown, an ashtray is provided, which includes a shell 100, and an igniter 200, an ash bin 300, a single-source multi-point synchronous drive mechanism and a cover body 400 arranged on the shell 100, the single-source multi-point synchronous drive mechanism includes a first transmission assembly 500, a second transmission assembly 600 and a drive source 700, the first transmission assembly 500 is drivingly connected to the igniter 200; the second transmission assembly 600 is drivingly connected to the ash bin 300; the output end of the drive source 700 is drivingly connected to the first transmission assembly 500 and the second transmission assembly 600; wherein the output end of the drive source 700 is delayed-driven with the second transmission assembly 600, so that the first transmission assembly 500 and the second transmission assembly 600 are driven in sequence during a single drive of the drive source 700.

[0040] In this embodiment, an induction control system 800 is provided on the shell 100, and the induction control system 800 includes a sensor and a controller. The sensor is electrically connected to the controller, and the controller is electrically connected to the driving source 700. The sensor is any one of a photoelectric switch, a distance sensor, an infrared sensor or a laser radar. The controller is a host computer. The controller transmits a working signal to the driving source 700 according to the user signal detected by the sensor. When the user's hand approaches the sensor, the controller sends a driving signal to the driving source 700, so that the cover body 400 opens and the igniter 200 and the ash bin 300 rise.

[0041] The automatic ashtray in the prior art generally integrates the functions of lifting the igniter 200, lifting the ash bin 300 and automatically flipping the cover. However, in most of the automatic ashtrays on the market, these three functions are automatically controlled and driven by a separate driving source 700. In this embodiment, the shell 100 is arranged in a cubic structure, and the shell 100 has a mounting cavity with an opening facing upward, the end of the cover body 400 is rotatably connected to the opening edge of the mounting cavity, the ash bin 300 is slidably connected in the mounting cavity, and the opening inner cavity of the ash bin 300 is arranged in the same direction as the opening of the mounting cavity.

[0042] Specifically, when the driving source 700 is started, its output end first drives the first transmission assembly 500, driving the igniter 200 to perform a lifting action. A delayed driving mechanism is set between the output end of the driving source 700 and the second transmission assembly 600, so that when the first transmission assembly 500 is in the driving operation process, the second transmission assembly 600 is in a non-working state, and the ash bin 300 is stationary; as the driving source 700 continues to operate, after a certain delay, the second transmission assembly 600 drives the ash bin 300 to perform a lifting action; compared with the prior art, the igniter 200 and the ash bin 300 of the ashtray are usually driven by independent driving sources 700. This design leads to a large number of parts, a complex structure, and increases the technical problems of manufacturing cost and maintenance difficulty. This solution realizes multi-point drive through a single driving source 700, reduces the number of components such as motors and circuits, and reduces manufacturing costs and failure rates; and the delayed driving mechanism ensures that the action is strictly executed in time, completely avoids the risk of mechanical interference, and extends the service life of the equipment. The single drive source 700 provides centralized energy and combines timing control to reduce ineffective power consumption, which is particularly suitable for battery-powered scenarios.

[0043] like Figures 1 to 9As shown, in another embodiment of the present invention, the first transmission assembly 500 includes a first connecting swing arm 510 and a lifting frame 520, one end of the first connecting swing arm 510 is rotatably connected to the movable connecting rod 720, the other end of the first connecting swing arm 510 is rotatably connected to the lifting frame 520, the lifting frame 520 is slidably connected to the shell 100, and the igniter 200 is arranged at the top of the lifting frame 520.

[0044] like Figures 1 to 9 As shown, in another embodiment of the present invention, a third transmission assembly 900 is provided at the top of the lifting frame 520, and the third transmission assembly 900 is used to drive the end of the cover body 400 to rotate and move. Specifically, the third transmission assembly 900 includes a driving tooth block 910 and a driven tooth block 920, the driving tooth block 910 is formed at the top of the lifting frame 520, and the driven tooth block 920 is provided at the rotating end of the cover body 400, the driving tooth block 910 and the driven tooth block 920 are meshed and matched through the teeth of their outer side walls, and during the movement and lifting of the lifting frame 520, the driving tooth block 910 is lifted and lowered, and its teeth move linearly compared with the driven tooth block 920 and drive the driven tooth block 920 to rotate through the teeth on the driven tooth block 920, thereby rotating the cover body 400 to open or close the installation cavity. In this way, when the user needs to use the ashtray, the driving source 700 is started, the first transmission assembly 500 drives the igniter 200 to move upward through the lifting frame 520, and the lifting frame 520 drives the cover body 400 to rotate through the driving gear block 910 and the driven gear block 920, so that its end is away from the shell 100. When the lifting frame 520 moves to a preset height, the second transmission assembly 600 drives the ash bin 300 to rise, and the single driving source 700 drives the igniter 200, the ash bin 300 and the flip cover in a preset order through multi-point transmission.

[0045] like Figures 1 to 9As shown, in another embodiment of the present invention, the second transmission assembly 600 includes a lifting plate 610 and a second connecting swing arm 620, the lifting plate 610 is fixedly arranged on the ash bin 300, both ends of the lifting plate 610 are slidingly connected to the inner wall of the shell 100, one end of the second connecting swing arm 620 is rotatably connected to the output end of the driving source 700, and a connecting slide groove 630 is arranged on the lifting plate 610, and the other end of the second connecting swing arm 620 is slidably connected in the connecting slide groove 630. Specifically, when the second connecting swing arm 620 is driven by the driving source 700, the end of the second connecting swing arm 620 can move on the lifting plate 610 along the length direction of the connecting slot 630. During the movement of the second connecting swing arm 620, the lifting plate 610, the shell 100 and the ash bin 300 are in a relatively static state; when the end of the second connecting swing arm 620 abuts against the extreme position end of the connecting slot 630, the second connecting swing arm 620 cannot continue to move along the connecting slot 630. Under the driving force of the driving source 700, the two ends of the second connecting swing arm 620 adapt to the rotational deflection compared with the output end of the driving source 700 and the lifting plate 610, thereby driving the lifting plate 610 to move in a straight line, so that the ash bin 300 moves.

[0046] like Figures 1 to 9 As shown, in another embodiment of the present invention, the moving direction of the output end of the driving source 700 is arranged parallel to the length direction of the lifting plate 610, and the connecting slide groove 630 is arranged parallel to the length direction of the lifting plate 610. In this embodiment, the housing 100 is placed on a horizontal plane, the lifting plate 610 is fixedly connected to the middle position of the bottom of the ash bin 300, and the lifting plate 610 can drive the ash bin 300 to move linearly in the vertical direction under the driving action of the driving source 700.

[0047] like Figures 1 to 9 As shown, in another embodiment of the present invention, the connecting groove 630 is arranged in a waist-shaped structure. During the sliding process of the end of the second connecting swing arm 620 along the straight section of the connecting groove 630, the lifting plate 610 and the shell 100 are relatively stationary.

The use of two groups of symmetrically arranged second connecting swing arms 620 is conducive to improving the moving stability of the lifting plate 610, and preventing the second transmission assembly 600 from being subjected to unidirectional force, which affects the moving effect of the lifting plate 610.

[0049] like Figures 1 to 9 As shown, in another embodiment of the present invention, the lifting plate 610 is provided in a plate strip structure, the inner wall of the shell 100 is vertically provided with a guide shaft 110, both ends of the lifting plate 610 are slidably connected to the guide shaft 110, and the lifting plate 610 is provided with a receiving groove 640 for accommodating the end of the second connecting swing arm 620 along its axis, the receiving groove 640 is connected to the connecting slide 630, and the end of the second connecting swing arm 620 close to the connecting slide 630 is provided in a T-shaped structure.

The ash bin 300 is slidably connected to the guide shaft 110.

[0050] like Figures 1 to 9 As shown, in another embodiment of the present invention, the driving source 700 includes a driving member 710 and a movable connecting rod 720, one end of the movable connecting rod 720 is rotatably connected to the second connecting swing arm 620, and the other end of the movable connecting rod 720 is rotatably connected to the first transmission assembly 500, the output end of the driving member 710 is drivingly connected to the end of the movable connecting rod 720 and the driving member 710 is used to drive the movable connecting rod 720 to move linearly in the shell 100.

Wherein, the length of the first connecting swing arm 510 is greater than that of the second connecting swing arm 620.

[0052] In this embodiment, the driving member 710 includes a driving motor 711, a driving gear 712 and a driving rack 713.
