[0002] The intelligent assisted driving of existing vehicles, including electric vehicles and engineering vehicles, is limited to a whole set of accessories pre-installed on the vehicle to achieve remote control. This method greatly limits the scope and range of intelligent driving coverage, especially gear control, which relies heavily on a whole set of instruments and sensors.

[0003] The existing patent, patent application number 201720113478.4, entitled "An FSAE pneumatic shifting device with data recording function," possesses the characteristics of "the FSAE pneumatic shifting device and method with data recording function described in this utility model has low cost, can greatly improve the driver's shifting efficiency, improve the level of shifting automation, and reduce the driver's burden when shifting gears. It can also display the vehicle's running status, record various vehicle condition information, and provide prompts to the driver when necessary." However, it still has some shortcomings, such as the double-acting cylinder and shifting rocker arm only being able to perform shifting actions in a single direction, and not being able to be directly installed on existing equipment. Due to the direct connection during installation, the device is difficult to simultaneously accommodate manual control. Therefore, a shifting device that can be remotely controlled is proposed.

[0024] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0027] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0028] like Figures 1-3As shown in the figure, the present invention proposes a shift device capable of remote control, including a platform plate 1. A through groove hole 11 is recessed in the middle of the platform plate 1. A shift lever 10 passes upward from below the through groove hole 11. A cylinder 1 5 is provided on each of the front and rear surfaces of the platform plate 1. A push plate 1 9 is provided at the movable end of the cylinder 1 5. A cylinder 2 6 is provided on each side of the platform plate 1. A push plate 2 8 is provided at the movable end of the cylinder 2 6. The length of the push plate 2 8 is greater than that of the push plate 1 9. The cylinder 1 5 and the cylinder 2 6 are arranged around the through groove hole 11. The through groove hole 11 is a rectangle with chamfers at all four corners;

[0029] Both the cylinder 1 5 and the cylinder 2 6 are connected to a solenoid valve 12 through a connecting air pipe 1 7. The solenoid valve 12 is connected to a manifold 14 through a connecting air pipe 2 13. A manifold 14 is provided on the connecting air pipe 2 13. The manifold 14 is connected to a gas supply member 15.

[0030] Four support frames 2 are provided at the bottom of the platform plate 1. The support frames 2 are arranged vertically. Fixed holes are provided at the bottom ends of the support frames 2;

[0031] The support frames 2 facilitate the fixing of the platform plate 1 on the foundation.

[0032] The platform plate 1 is connected to the cylinder 1 5 through a mounting bracket 3. The mounting bracket 3 is in a U - shape. The lower side of the push plate 1 9 is higher than the upper side of the push plate 2 8;

[0033] The mounting bracket 3 enables the cylinder 2 6 and the cylinder 1 5 to work at different heights, thus not interfering with each other.

[0034] The gas supply member 15 is a gas supply pipeline or a high - pressure gas cylinder;

[0035] A driving high - pressure gas is provided by using a gas supply pipeline or a high - pressure gas cylinder.

[0036] A fixing plate 4 is provided at the bottom of the cylinder 2 6. The fixing plate 4 is fixedly connected to the upper side of the platform plate 1.

[0037] A shift baffle 16 is fixed above the through groove hole 11. A shift groove 17 is recessed in the shift baffle 16. The shift groove 17 is in a king - character shape;

[0038] The shift groove 17 is used to limit the movement track of the shift lever 10. The shift positions: 1, 2, 3, 4, 5 and R are marked on the shift baffle 16.

[0039] The model of the solenoid valve 12 is ZS - 15.

[0040] The specific implementation method is as follows: the air supply and demand are controlled by the solenoid valve 12, thereby controlling the action of cylinder 5 and cylinder 6: cylinder 5 and cylinder 6 extend or shorten, and the extension or shortening of cylinder 5 and cylinder 6 will adjust the posture of the shift lever 10. By using cylinder 5 and cylinder 6 to control the swing of the shift lever 10, the two cylinders 6 control the lateral relative position of the shift lever 10 and the shift groove 17, and the two cylinders 5 control the vertical relative position of the shift lever 10 and the shift groove 17.

[0041] This allows the gear shift lever 10 to precisely reach one of the gears 1, 2, 3, 4, 5, and R along the gear shift groove 17, thereby achieving remote positioning and adjustment of the gear and enabling remote control of electric vehicles and engineering vehicles, thus cooperating with other equipment to achieve intelligent assisted driving.

[0042] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0043] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
