[0032] For a clearer understanding of the technical features, objectives, and effects of the utility model, the detailed implementation manner of the utility model will now be described with reference to the accompanying drawings. In each figure, the same reference numerals denote components having the same or similar structures but the same functions.
[0033] In this document, "schematic" means "serving as an example, instance, or illustration", and any illustration or implementation manner described as "schematic" in this document should not be construed as a more preferred or more advantageous technical solution.
[0034] Figure 1 It is a schematic structural diagram of a schematic implementation manner of an automobile engine hood opening and closing device. Figure 2 It is a schematic diagram of the usage state of an automobile engine hood opening and closing device. In Figure 2 the first direction W is perpendicular to the page direction. Referring to Figure 1 and Figure 2 , the automobile engine hood 70 can rotate about an axis parallel to the first direction W to open or close. The automobile engine hood opening and closing device includes a track 10, a driving motor 20, and an electric telescopic support rod 30.
[0035] The track 10 can be fixed to the inner side of the automobile engine hood 70, and the track 10 extends in a direction perpendicular to the first direction W. The body of the driving motor 20 can be fixed to the engine compartment of the automobile, and the output shaft of the driving motor 20 is parallel to the first direction W.
[0036] The electric telescopic strut 30 is composed of a motor, a speed reducer, a threaded rod, etc., and is perpendicularly connected to the output shaft of the driving motor 20 in the first direction W. Figure 3 and Figure 4 FIG. is a schematic diagram of the use state of the automobile hood opening and closing device. In Figure 3 and Figure 4 the first direction W is perpendicular to the page direction. Referring to Figures 2 to 4 , the electric telescopic strut 30 has a support end 32. The support end 32 can move within the track 10, and the support end 32 can also rotate relative to the track 10 about an axis parallel to the first direction W. In the illustrative embodiment, the support end 32 includes a roller 33. The roller 33 can rotate about an axis parallel to the first direction W, and the support end 32 moves within the track 10 through the roller 33. The structure of the roller 33 is simple and convenient for production and processing. However, it is not limited thereto. In other illustrative embodiments, the support end 32 can also adopt other structures capable of moving within the track 10.
[0037] Referring to Figure 2 and Figure 3 , the driving motor 20 can drive the electric telescopic strut 30 to rotate and cooperate with the elongation of the electric telescopic strut 30 to drive the opening and support of the closed automobile hood 70. The driving motor 20 and the electric telescopic strut 30 can cooperate to support the automobile hood 70 at any angle. For example, in Figure 2 the automobile hood 70 is in a fully open state, and in Figure 3 the automobile hood 70 is in a semi-open state. Referring to Figure 4 , the driving motor 20 can also drive the electric telescopic strut 30 to rotate and cooperate with the shortening of the electric telescopic strut 30. When the opened automobile hood 70 lacks support, it will close under the action of gravity.
[0038] For the automobile hood opening and closing device provided by the present utility model, the driving motor 20 fixed to the engine compartment of the automobile drives the electric telescopic strut 30 to rotate, cooperates with the telescopic movement of the electric telescopic strut 30, and utilizes the support end 32 of the electric telescopic strut 30 to slide within the track 10 fixed to the inner side of the automobile hood 70, realizing the functions of automatically opening and closing the automobile hood, which is convenient for users.
[0039] In the illustrative embodiment, referring to Figure 1, the automobile hood opening and closing device further includes a driving member 21 and a strut base 31.

[0041] Figure 5 FIG. is a partial structural schematic diagram of another schematic embodiment of the automobile hood opening and closing device. Referring to Figure 5 , which is the same as or similar to the automobile hood opening and closing device in Figure 1 will not be described in detail. The difference is that the automobile hood opening and closing device further includes a controller 40 which is connected to the driving motor 20 and the electric telescopic strut 30 through a cable. The controller 40 can send control signals to control the driving motor 20 and the electric telescopic strut 30 to drive the automobile hood 70 to open or close. In a schematic embodiment, the controller 40 is an in-vehicle host system, whereby the opening or closing of the automobile hood can be controlled through the screen operating system in the vehicle.
[0042] In a schematic embodiment, referring to Figure 5 , the automobile hood opening and closing device further includes a remote controller 50 which can communicate with the controller 40 wirelessly. The remote controller 50 can be operated and send wireless signals to the controller 40. The controller 40 can receive the wireless signals and send control signals to control the driving motor 20 and the electric telescopic strut 30. Thereby, the remote control of opening and closing the automobile hood 70 is realized. In a schematic embodiment, the remote controller 50 is an automobile remote control key. Integrating the opening and closing functions of the automobile hood into the automobile remote control key is more convenient for the user to operate and control.
